Introduction

Among botanists and explorers of the 20th century in tropical South America, Augusto Weberbauer is clearly one of the most renowned, thanks to his collections and publications about the vegetation and flora of Peru (Weberbauer, 1911, 1936, 1945). Weberbauer arrived in Peru in November of 1901, and over a period of approximately 35 years (1901-1905, 1908-1939) collected over 8000 plant specimens (Velarde, 1968), almost one-fifth of which were recognized as new to science.

Weberbauer’s collections were mostly described by botanists at Berlin-Dahlem (B), where his main collection was sent, in addition to duplicates distributed to American and other European institutions, including to the herbarium of the Museum of Natural History (WRSL) in his city of birth, Breslau (Wroclaw), presently located in Poland (Velarde, 1968). Most of his collections at Berlin were destroyed during World War II (WWII), and many present-day botanists do not realize that a substantial set of his collections is currently kept in the Weberbauer Herbarium (MOL) of the Universidad Nacional Agraria La Molina, in Lima, Peru, with a few collections held at Herbarium San Marcos (USM) of the Universidad Nacional Mayor de San Marcos, also in Lima. Unfortunately, some lectotypifications and neotypifications have even left out those of his specimens kept in Peru.

The type legacy of Weberbauer in Peru was partially accounted for by Velarde (1968, 1969), who as discussed by León et al. (2006), involuntarily lectotypified some names using duplicates kept at the MOL herbarium. Velarde’s papers followed the arrangement of Engler’s classification system, but only listed a total of 700 names for several families (except those in the subclass Sympetalae), and thus did not include the Ericaceae. However, thanks to the recent cataloguing of his complete collection at MOL (see León et al., 2006); it is possible to clarify both nomenclature and geographical data.

The Ericaceae are one of the most conspicuous families in the Andean flora, and thus Weberbauer mentioned several species as important elements of the montane forest flora community. He (Weberbauer, 1911, 1945) also included illustrations of some taxa probably based on his own collections vouchered at MOL.

As documented in this paper, a total of 108 Weberbauer collection numbers are known to be Ericaceae, of which 48 are currently found at MOL; these are listed below. Based on our herbarium search, a total of 49 species of Ericaceae have had their types based on Weberbauer collections and, theoretically, duplicates of these may have been deposited at MOL. Of these potential 49 Ericaceae type collections, however, only 18 have been located at MOL and are herein newly designated lectotypes or isotypes. In addition to these 18 newly designated Weberbauer type collection numbers at MOL, 11 more Weberbauer lectotypes or isotypes are herein designated at F (1), G (2), NY (7), and US (1).

Ericaceae collected by Weberbauer

The following list gives all the known Weberbauer collection numbers of Ericaceae based on literature reports and extant herbarium collections. Those numbers in boldface italics have been used as the bases for types; those numbers with an additional boldface asterisk (*) in front of them have been designated as lectotypes (or isolectotypes) at MOL. The scientific name, following the Weberbauer collection number, is the identity given to the original collection. Two isotypes have also been located at the herbarium in the Museo de Historia Natural of the Universidad Nacional Mayor de San Marcos (USM) in Lima.

975 Pernettya prostrata (Cav.) DC. – Luteyn (1995a) annotated this Weberbauer collection number as P. prostrata (Cav.) DC. The specimen at MOL bears their bar code no. 3582.

1081 Cavendishia peruviana Hoerold – The holotype at B was destroyed during WWII and there are no known isotypes. The lectotype (designated by Luteyn, 1983) is the photo of the B holotype specimen represented by ACS neg. 13-A. The photo shows two separate twigs of which the larger-leaved (lower right-hand side) agrees with the protologue and that piece was designated as lectotype. Luteyn (1983) recognized this collection number as C. bracteata (Ruiz & Pavón ex J. St.-Hil.) Hoerold.

1081a Cavendishia pubescens (Kunth) Hemsley var. microphylla Hoerold – The holotype at B was destroyed during WWII and there are no known isotypes. The lectotype (designated by Luteyn, 1983) is the NY sheet with fragments ex B attached to a photo of the B holotype specimen represented by ACS neg. 15. Luteyn (1983) annotated this collection number as C. bracteata (Ruiz & Pavón ex J. St.-Hil.) Hoerold.

1090 Gaultheria sp. – This Weberbauer collection number has not been found in any Peruvian herbarium or elsewhere, and its identity is unknown. It was cited by Weberbauer (1945: 573).

1150 Gaultheria sp. – This Weberbauer collection number has not been found in any Peruvian herbarium or elsewhere, and its identity is unknown. It was cited by Weberbauer (1945: 573).

*1770 Cavendishia ulbrichiana Hoerold – The holotype at B was destroyed during WWII. Luteyn (1983) designated the photo of the B holotype specimen, represented by ACS neg. 19, as the lectotype. However, the discovery of a duplicate sheet of Weberbauer 1770 at MOL means that the actual sheet at MOL, bearing their bar code no. 3567, is herein designated as the lectotype of C. ulbrichiana, overturning Luteyn’s designation in 1983. Luteyn (1983) also annotated this collection number as C. bracteata (Ruiz & Pavón ex J. St.-Hil.) Hoerold, and this was verified by EO in 2006.

1971 Bejaria glauca Bonpl. – Clemants (1995) annotated this Weberbauer collection number as B. aestuans L. The duplicate at MOL bearing their bar code no. 3511 has been annotated by EO as B. aestuans.

1972 Cavendishia kraenzliniana Hoerold – The holotype at B was destroyed during WWII and there are no known isotypes. This number is not present at any Peruvian herbarium. The lectotype (designated by Luteyn, 1983) is the photo of the B holotype specimen represented by F neg. 4669 and ACS neg. 178. Luteyn (1983) also annotated this collection number as C. punctata (Ruiz & Pavón ex J. St.-Hil.) Sleumer.

2055 Thibaudia engleriana Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4626 and ACS neg. 131. This number is not present at any Peruvian herbarium. This species is restricted to Peru (León, 2007).

The MOL isotype sheet with their bar code no. 3576 is herein designated as the lectotype of T. apophysata. The fragment at NY ex the B holotype is herein designated as an isotype. This taxon is restricted to Peru (León, 2007).

2077 Ericaceae – Luteyn (1995b) recognized this Weberbauer collection number as Gaultheria tomentosa Kunth. The duplicate sheet at MOL bears their bar code no. 3660 and was annotated by Luteyn in 2006. This collection may have been the basis for the illustration on p. 523 of El Mundo Vegetal (Weberbauer, 1945).

*2079 Disterigma weberbaueri Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4643. There are fragments ex the B holotype at both F and NY. A full and complete isotype of this collection number is at MOL bearing their bar code no. 3673, and it is herein designated as the lectotype of D. weberbaueri by Dr. Paola Pedraza (former New York Botanical Garden graduate student who monographed Disterigma) [= D. empetrifolium (Kunth) Drude].

2086 Gaultheria glomerata (Cav.) Sleumer – The sheet of Weberbauer 2086 at G (with fragment at L) was mistakenly determined by Sleumer as an isotype of G. apiculata; it is actually G. glomerata. The duplicate sheet of Weberbauer 2086 at MOL bearing their bar code no. 3659 was annotated by Luteyn in 2006 as Gaultheria glomerata.

2122 Sophoclesia weberbaueri Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4730. This number is not present at any Peruvian herbarium. Fragments at NY ex the B holotype are herein designated as the lectotype of Soph. weberbaueri. The taxonomy of this species is uncertain, and Luteyn recognized this collection number as Sphyrospermum buxifolium – Sph. cordifolium “complex”.

*2143 Gaultheria glandulosissima Sleumer – The holotype at B was destroyed during WWII, but is represented in photo by F neg. 28926 of the isotype at G. In 1952, the isotype sheet at MOL (now with their bar code no. 3661) was annotated and photographed (un-numbered) by Sleumer as an isotype of G. glandulosissima; there is a print of this photo at NY. The isotype at G was designated lectotype by Luteyn (1995b) and fragments at US as isolectotype. On 19 June 2006, Luteyn annotated the MOL isotype as duplicate of the lectotype and it is herein designated as such. This collection number is recognized by Luteyn (1995b) as Gaultheria erecta Vent.

2146 Gaultheria sp. – The duplicate sheet of this Weberbauer collection number at MOL bears their bar code no. 3667 and was determined as G. glabra DC. In 2007, EO updated the determination as G. reticulata Kunth. This specimen is cited by Weberbauer (1945: 542).

*2151 Psammisia weberbaueri Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4705 and ACS neg. 157. On 19 June 2006, Luteyn annotated the sheet at MOL with their bar code no. 3591 as lectotype of P. weberbaueri and it is herein designated as such. Another duplicate sheet at MOL with their bar code no. 3592 has just two leaves, but represents an isotype. The fragments at NY ex the B holotype are also herein designated as an isotype. Luteyn recognizes this collection number as P. coarctata (Ruiz & Pavón ex G. Don) A. C. Sm.

2202 Ceratostema urbanianum Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by ACS neg. 50. This number is not present at any Peruvian herbarium. Fragments at NY ex the B holotype are herein designated as the lectotype of C. urbanianum [= Pellegrinia grandiflora Ruiz & Pavón ex G. Don) Sleumer].

2213 Disterigma empetrifolium (Kunth) Nied. [Junín. Tarma: W of Huacapistana, 3100-3500 m]. This Weberbauer collection was seen at G, but is not found at any Peruvian herbarium.

2442 Cavendishia ulbrichiana Hoerold – Luteyn (1983) recognized this Weberbauer collection number as Cavendishia bracteata (Ruiz & Pavón ex J. St.-Hil.) Hoerold. The sheet at MOL bears their bar code no. 3696 and according to Ortiz belongs also in C. bracteata.

2505 Ceratostema coccineum Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4644 and ACS neg. 35. This number is not present at any Peruvian herbarium. Fragments at NY ex the B holotype are herein designated as the lectotype of C. coccineum [= Pellegrinia coccinea (Hoerold) Sleumer].

2508 Gaultheria sp. – This Weberbauer collection number has not been found in any Peruvian herbarium or elsewhere, and its identity is unknown. It was cited by Weberbauer (1945: 544).

3274 Pernettya pentlandii DC. – Luteyn (1995a) recognized this Weberbauer collection number as P. prostrata (Cav.) DC. The sheet at MOL bears their bar code no. 3583 and was also verified by EO in 2005 as P. prostrata.

3358 Thibaudia cardiophylla Sleumer – The holotype sheet at B was destroyed during WWII and there are no known isotypes. Sleumer (1934) compared it to T. engleriana Hoerold, but no other collections are known and it does not compare with anything we know.

*3370 Gaultheria bicolor Sleumer – The holotype sheet at B was destroyed during WWII. The isotype at MOL bearing their bar code no. 3569 is herein designated as lectotype of G. bicolor. Luteyn (1995b) recognized this specimen as G. bracteata (Cav.) G. Don, which was verified by EO in 2005 on the basis of the MOL sheet.

3374 Ceratostema harmsianum Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4646 and ACS neg. 32. There are no other isotypes known [=Pellegrinia harmsiana (Hoerold) Sleumer].

3377 Gaultheria sp. – This Weberbauer collection number has not been found in any Peruvian herbarium or elsewhere, and its identity is unknown. It was cited by Weberbauer (1945: 534).

3379 Gaultheria sp. – Luteyn (1995b) recognized this Weberbauer specimen as G. vaccinioides Wedd. Ortiz (in 2005) annotated the collection at MOL also as G. vaccinioides. This specimen bears their bar code no. 3662. It was cited by Weberbauer (1945: 534).

*3402 Gaultheria weberbaueriana Sleumer – The holotype sheet at B was destroyed during WWII, but is represented in photo at NY by a print of the MOL isotype. Luteyn (1995b: 476) designated the MOL sheet as lectotype based on the photo he had in his possession (at NY) given to him in 1978 and presumably taken by H. O. Sleumer in 1952. It was not until 19 June 2006 that Luteyn actually annotated the sheet at MOL with their bar code no. 3663 as lectotype of G. weberbaueriana, and it is herein designated as such. Luteyn (1995b) recognized this collection number as G. erecta Vent.

3419 Bejaria hispida Poepp. & Endl. – Clemants (1995) recognized this Weberbauer specimen as B. aestuans L. The collection at MOL bears their bar code no 3502 and was annotated by EO (in 2005) as B. aestuans.

3466 Bejaria glauca Kunth – Clemants (1995) recognized this Weberbauer specimen as B. aestuans L. The collection at MOL bears their bar code no 3509 and was annotated by EO (in 2005) as B. aestuans.

*3510 Psammisia engleriana Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4687 and ACS neg. 144. On 19 June 2006, Luteyn annotated the sheet at MOL bearing their bar code no. 3590 as lectotype of P. engleriana and it is herein designated as such. Fragments at F and NY ex the B holotype are herein designated as isotypes. Luteyn recognizes this specimen as P. coarctata (Ruiz & Pavón ex G. Don) A. C. Sm.

3518 Cavendishia urbaniana Hoerold – Weberbauer 3518 is the collection number given for the type of C. urbaniana Hoerold as stated in the protologue and as evidenced by a photo of the B holotype (F neg. 4680 and ACS neg. 18). That species was synonomized under C. nobilis Lindl. var. nobilis by Luteyn (1983). Although a duplicate sheet of Weberbauer 3518 exists at MOL with their bar code no. 3695, a careful examination shows that the actual specimen at MOL is, in reality, a collection of C. bracteata not C. nobilis, so the collection 3518 in this herbarium should not be considered a lectotype.

*3519 Gaultheria opaca Sleumer – The holotype sheet at B was destroyed during WWII, but is represented in photo at NY by an un-numbered print of the isotype sheet at MOL given to JLL in 1978 and presumeably taken by H. O. Sleumer in 1952. The isotype sheet at MOL with their bar code no. 3664 was annotated as the lectotype of G. opaca by JLL on 19 June 2006 and is herein designated as such. Luteyn (1995b) recognized this collection number as G. erecta Vent.

3542 Thibaudia harmsiana Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4630 and ACS neg. 136. Fragments of the holotype and a photograph are present at NY and are herein designated lectotype of T. harmsiana. This number is not present at any Peruvian herbarium. The species is restricted to Peru (León, 2007).

3546 Disterigma humboldtii (Klotzsch) Niedenzu – The duplicate sheet of this Weberbauer collection number at MOL bears their bar code no. 3674. This collection might have been used for the illustration on p. 521 in El Mundo Vegetal (Weberbauer, 1945).

*4014 Bejaria weberbaueriana Mansf. & Sleumer – The holotype sheet at B was destroyed during WWII, but is represented in photo by the F neg. 28917 of the G isotype. Clemants (1995) designated the isotype at G as lectotype, citing also a fragment at F ex the B holotype. Clemants (1995) recognized this collection number as B. resinosa Mutis ex L.f. At MOL there is also an isotype bearing their bar code no. 3499 and the annotation “B. caxamarcensis H.B.K.” The MOL sheet was annotated as B. resinosa by EO in 2007, and is herein designated as an isotype. Weberbauer (1945: p. 500, fig. 53) may have used this collection as the basis for his illustration of the species.

4283 Ericaceae – This Weberbauer collection number was located and photographed at MOL by EO in 2007; it bears their bar code no. 3568. EO determined this number as Vaccinium didymanthum Dunal on account of its crenate leaves and tubular corollas. A duplicate was located at G by JLL in 2007 and also annotated as the same taxon.

4300 Ericaceae – This Weberbauer collection number at MOL bears their bar code no. 3508 and was identified as Bejaria glauca var. tomentella Mansf. & Sleumer. Clemants (1995) recognized the MOL duplicate as B. mathewsii Fielding & Gardner, and this was confirmed by EO in 2007.

*4339 Thibaudia weberbaueri Hoerold – The holotype sheet at B was destroyed during WWII, but is represented in photo by F neg. 4638 and ACS neg. 140. The isotype sheet at MOL bearing their bar code no. 3575 was annotated as the lectotype of T. weberbaueri by JLL and EO in 2007 and is herein designated as such. In 1932, A. C. Smith synonymized the name under T. angustifolia Hook.

4347 Vaccinium pseudocaracasanum Sleumer – The holotype sheet at B was destroyed during WWII and there are no known isotypes. This number is not present at any Peruvian herbarium. Fragments at US ex the B holotype do exist, however, and are herein designated lectotype of V. pseudocaracasanum.

*4362 Leucothoe andina Sleumer – The sheet at MOL bears their bar code no. 3549 and is herein designated as the lectotype of Leucothoe andina. This collection number at MOL was annotated by Sleumer in 1952. There is also an isolectotype fragment at NY, and a photo of the MOL sheet taken by Sleumer (in 1952) and given to Luteyn. Judd (1995) recognized this collection number as Agarista albiflora (B. Fedtsch. & Basil.) Judd.
