This sketchshows a slender plant with wand-like stems and linear, bract-likeleaves. The inflorescence is loose, somewhat one-sided, and few-flowered. Contrary to the description published by Grisebach,the middle division of the labellum, as shown by the sketch, ismuch shorter than the lateral divisions. The material from whichthe sketch was prepared was collected in Trinidad by Dr. Crueger,and was used by Grisebach in his work on the Flora of the BritishWest Indian Islands;

The material from whichthe sketch was prepared was collected in Trinidad by Dr. Crueger,and was used by Grisebach in his work on the Flora of the BritishWest Indian Islands; consequently the discrepancy between thedescription and the material at Kew is of unusual interest. Kranzlin, in Orchidacearum Genera et Species, states that theanterior division of the petals is longer than the posterior division,but not twice longer, as described by Grisebach, and he describesthe labellum as tripartite, with the middle division about twiceas long as the lateral ones.
