Cyrtochilum kraenzlinianum and Cyrtochilum maasii spp. nov. (Orchidaceae, Oncidieae) from Colombia
Abstract
Two new orchid species from the Cyrtochilum halteratum-alliance, Cyrtochilum kraenzlinianum and C. maasii, are described and illustrated based on Colombian material. Both novelties are similar to C. halteratum, but they are separable from this species based on floral characteristics. Information about the habitat and ecology of the new species as well as brief notes on their taxonomic affinities are provided.
... Our recent studies on Colombian oncidioid orchids resulted in the discovery of several new species (e.g. Szlachetko & kolanowSka 2014b, 2014c. Three novelties within Brevilongium are described and illustrated here, and a key to the identification of its representatives in Colombia is provided. ...
Three new species of Brevilongium from Colombia are described and illustrated: Brevilongium callejasii Szlach., Kolan. & Skorowska, Brevilongium schultesii Szlach., Kolan. & Skorowska, and Brevilongium chitaraquensis Szlach., Kolan. & Skorowska, The taxonomic affinities of the novelties within the genus are discussed. Including the species described in the present paper, the genus Brevilongium now comprises 14 species. A key to the nine species currently known from Colombia is provided.
This article is a presentation of taxonomic diversity of the orchid genusCyrtochilumin Northwestern South America. The morphological characteristics of over 90 speciesoccurring in northern Peru, Ecuador, Colombia and Venezuela are presentedtogether with illustrations of theirfloral segments. Information about the distributionof each taxon is provided. Ten morphologically consistent groups have beendelineated to facilitate identification ofCyrtochilumrepresentatives in the studiedarea. Keys for determination of species within each group are provided. Seven newspecies ofCyrtochilumare described and one new combination is proposed.
