“…The specimen of Triana 4668 in NY does not correspond with H. trianae or any of the other species treated here, in contrast with the specimen with the same number in COL. Triana’s numbers do not correspond to field collection numbers as currently used, but instead are generic numbers based on the Endlicher system ( Kirkbride 1982 ; Aymard 2017 ).…”

Hydrangea section Cornidia, currently consisting of 19 accepted taxa, occurs from Mexico to Chile and Argentina, with one species in southeast Asia. Its representatives are root-climbing lianas which may grow up to 60 m high in the tree canopy of temperate to (sub)tropical forests. Our extensive field work throughout its distribution area, study of herbarium specimens and ongoing molecular studies have resulted in the discovery of species new to science, as well as new insights into the circumscription of many taxa. We here present amended descriptions for seven Hydrangea species of Central and South America and discuss the taxonomical situation of two Colombian Hydrangeas, including an identification key, illustrations, and distribution maps. Field work was carried out in Costa Rica, Panama, Ecuador and Peru, including exploration in areas where the genus had not been collected before. These specimens and observations were complemented with the study of specimens of 41 herbaria of North, Central and South America, as well as Europe. Detailed morphological studies of all species were carried out, based on living plants in their natural habitat, as well as on dried specimens from our own collections and all available herbarium material. Type material was studied in detail for all species concerned. Based on an extensive number of morphological characters, combined with distribution patterns, phenological differences and ecological preferences, including molecular data in most cases, Hydrangea peruviana and H. oerstedii are clearly distinct taxa, as well as the other seven species mentioned here, which had been synonymized with either of these two species. The present study results in the recognition of 26 species in section Cornidia and exemplifies the urgent need for profound taxonomic studies in plants, as in many families we do not dispose of well-circumscribed units for conservation to mitigate the already occurring unprecedented loss of biodiversity.

“…Kirkbride (1982) noticed the ambiguity of these multiple localities and suggested that they could refer to mixed collections or later finds of the same species at other localities. This fact constitutes a setback in establishing the correspondence among duplicates of each gathering, that in most cases are currently deposited in different herbaria, as has been mentioned by Aymard (2017).…”

The specimens collected by José Jerónimo Triana are an important legacy of the first major scientific expedition organized by the government of Nueva Granada, present-day Colombia: the Chorographic Commission. After finishing his duties in the Commission, Triana gave to the Colombian government a complete set of his specimens in 1856, along with a catalog where he taxonomically organized and numbered his collections. After traveling to Europe in May 1857, carrying part of his herbarium, Triana prepared a new catalog in which he reorganized the numbering of his collections, and added at least three additional number series: the serial numbers (i.e., Triana "collection numbers"), the "Linden" numbers, and the number of duplicates for each gathering. The use of different number series in the two catalogs and on the labels of duplicates of the same gathering stored in numerous herbaria around the world has produced ambiguity in the designation of type specimens collected by Triana. These nomenclatural issues were analyzed, and a guideline is presented for lectotypifying plant names for which Triana's specimens were used as types. Sixty-five Triana specimens already deposited in COL were newly identified as types of 62 species names from 36 families, after establishing their proper correspondence to duplicates currently stored in different European herbaria.
