Finding
SITF has determined this plant to be Barbosella cogniauxiana, not Barbosella dusenii (Dec 2025). The plant and flowers shown in the images of B. cogniauxiana in the POWO closely match this plant. These flowers are slightly larger than B. dusenii and there is no evidence of a lip with protruding calli or hairy basal cavity characteristic of B. dusenii. The lip on this flower has a shallower cavity and less prominent calli than would be characteristic of B. cogniauxiana. Luer's Icones 20 describes Barbosella dusenii as distinguished by the twice smaller vegetative parts, the tiny leaves being broadly elliptical. The flowers of B. dusenii are slightly smaller than those of B. cogniauxiana, and differ only in minor details of the lip. Both have shallow articulations with a bulbous tip of the column foot, but the pair of calli on the center of the disc is more prominent in B. dusenii.
