The lectotypification of six names of species, originally described as Evelyna Lind. (Orchidaceae), based on collections of Jean Jules Linden from locations that are currently in Venezuela and Colombia, is proposed. We also provide the number and location of duplicates of the type material.
Elleanthus, Evelyna, Jean Jules Linden, lectotype, nomenclature, syntype
The Neotropical orchid genus Elleanthus was proposed by Czech botanist Carl Borivoj Presl in 1827 (Presl 1927). As the genus has never been comprehensively taxonomically revised, we can assume that it currently comprises over 120 species (
Over the years, researchers have described a few similar genera, Evelyna Poepp. & Endl., Adeneleterophora Barb.Rodr. and Epilyna Schltr., which have been considered synonymous with Elleanthus (
Many orchid species were described in the 19th century without indicating any type material, or information about the location of the reference collection. The examination of any original material cited in the protologue is a remarkable step in taxonomic work. Our studies towards revising the genus Elleanthus sensu lato has revealed specimens, belonging to the Jean Jules Linden’s gatherings, where
Jean Jules Linden was a Belgian botanist and was particularly fond of orchids. His first scientific expedition to Brazil lasted less than two years (September 1835–March 1837). Nicolas Funck, Auguste Ghiesbreght and he collected and brought back to Europe a large collection of plants and animals. During the following expedition (September 1837–December 1840) to Cuba and Mexico, he focused mainly on observing the habitat of orchids and collected them for breeding purposes and for adding to European herbaria. He was the first botanist whose findings revolutionised the cultivation of orchids in Europe (
Currently, we are carrying out a revision of Elleanthus sensu lato (in preparation), which is proving that some names of species are lacking type. In order to stabilise the nomenclature of these species, they require typification. Therefore, in this paper, a lectotypification of the names of species of Elleanthus described from Linden’s gathering is proposed. For one name, we could not indicate a lectotype and this is widely discussed.

In the protologue of Evelyna bractescens,
During our research in herbaria, we located only a single Linden 2215 collection corresponding to Evelyna bractescens. It is deposited in the Naturhistorisches Museum in Vienna (W-R13950). This sheet includes five plant fragments and Reichenbach’s drawing, signed as E. bractescens and Lin. 2215 (Fig.

In the protologue of Evelyna coriifolia Rchb.f., the author indicates the gathering Linden 1272 as the type. We found only one specimen of this collection deposited in the Naturhistorisches Museum in Vienna (Fig.
In addition, in Kew, there is a sheet which bears a drawing made on the basis of a specimen from Vienna. It is marked as a type as well; however, it was not made by the author of the species. According to the Code of Nomenclature (

In the protologue of Evelyna ensata Lind., the author indicates in a short note the gathering of Linden 664 as the type. We found that this collection actually consists of three specimens deposited in two institutions: the Naturhistorisches Museum in Vienna and the Muséum National d’Histoire Naturelle in Paris. The Vienna specimens have no annotation on their status, but they have a designation of the collection number Linden 664; the specimen stored in P is labelled as the type. We have analysed and compared all of them with the diagnosis. We analysed not only vegetative features, but also we compared the floral structures. These specimens have all the features of Evelyna ensata and one of them was selected as the lectotype (Fig.
There is a Reichenbach drawing kept at W (W-R30233), labelled E. ensata and numbered 644. In the protologue,

Basionym: Evelyna flavescens Lindl., Orchidaceae Lindenianae 10, no. 59. 1846. Type: Venezuela, Trujillo “between Humucoro-Bajo and the Agua de Obispo, in the Province of Truxillo, at the height of 7000 feet [2133 m], May”, Linden 625; Lectotype (designated here): K-L; isolectotypes: P (P00389695), W-R (W-R51662, W-R51664, W-R30242 [drawing]), BR (BR0000013083618).
In the short note following the protologue,
During our studies, we found five more specimens which are labelled Linden 625. Three of them are deposited in the Naturhistorisches Museum in Vienna, one in the Muséum National d’Histoire Naturelle in Paris and one in Meise Botanic Garden in Belgium. The specimens from Vienna have no type annotation, but do mention the collection as Linden 625. We analysed the vegetative and floral characteristics and compared them with the diagnosis; two of them (W-R51662 and W-R51664) represented Elleanthus flavescens. The third one (W-R30242) is a drawing which is likely based on the type material as the same collector and number are recorded on it as in the protologue.
The specimen deposited in the Paris Herbarium (P00389695) was labelled by Garay as Elleanthus furfuraceus (Lindl.) Rchb.f. However, we are of the opinion that it is a part of the type material of Elleanthus flavescens. This specimen has lanceolate, acuminate leaves, an oblong, cylindrical inflorescence which is loose at the base, floral bracts that are shorter than the flowers and a pair of ovate corpuscules at the base of the lip with a strongly thickened transverse ridge, just like E. flavescens. It also mentions the number Linden 625.
Elleanthus flavescens is more similar to E. aurantiacus than E. furfuraceus. Some authors, such as
