Finding
SITF confirms this plant as Anathallis citrina (Apr 2025). This plant matches the description and drawing in Luers Icones 18. Anathallis obovata is considered a similar species but the blooming habit is different. The drawing in the IOSPE appears different than this plant and may not be correct. Orchidroots has this species synonymous with A. obovata. POWO considers them to be separate species and I suspect the drawing and photo in the IOSPE of the more open flower may be A. obovata.
