A new species of Stellilabium Schltr. is described and illustrated based on Colombian material. The novelty is distinguished from the similar S. pogonostalix (Rchb. f.) Garay & Dunst. and S. alticola Dodson & Escobar by its ovate lip, which is broadest near the middle. An identification key for the Colombian Stellilabium species is provided.
A new species of Rodriguezia Ruiz & Pav. is described and illustrated based on material collected in Colombia. The novelty is distinguished by its subrectangular lip lamina, which is ornamented with an elevated pad extending to 3/4 of the lip. In contrast to R. lehmannii Rchb. f., in R. suarezii Kolan. & R. Medina Tr. leaf-bearing sheaths are observed at the base of its pseudobulb. An identification key for the Colombian Rodriguezia species is provided
Andinia panica, previously known exclusively from the type locality in Ecuador, is reported for the first time from Colombia. Characteristic of population found in Valle de Sibundoy is provided together with photographs of the specimen and information about its habitat. Moreover, the comparative morphology of species included in Andinia subgenus Minuscula, is presented together with the key to species identification.
A new species of Sertifera is described and illustrated based on Colombian material. The novelty resembles Sertifera colombiana, but it is characterized by glandular leaf sheaths, larger, white flowers, ovate to oblong-ovate sepals, ligulatelanceolate petals and apically triangular lip. This is the first report of a white-flowered representative of the genus.
A new species of Stellilabium Schltr. is described and illustrated based on material collected in Colombia. The new species is most similar to S. morganiae Dodson, but differs from it in flower morphology. The gynostemium appendages of the new entity are ovate and widely spreading; in S. morganiae they are relatively small, not spreading, and oblong-ovate, and do not exceed the lip basal part in width.
