Another Flower not See discussion below Photo by Carola Pahl

Common Name The Hairless Pleurothallis [refers to the hairless sepals]

Flower Size .2" [5mm]

Found in Costa Rica at elevations around 1100 to 2000 meters as a mini-miniature sized, warm to cool growing epiphyte with slender, erect ramicauls enveloped basally by 2 to 3 thin, tubular sheaths and carrying a single, apical, erect, coriacecous, obovate, obtuse to rounded apically, subpetiolate base leaf that blooms in the spring and fall on a subdense, secund, simultaneously several flowered, racemose inflorescence that is longer than the leaf

CAUTION I have my doubts about the second photo determination. The first photo by Daniel Jimenez is correct. The scientific name specifically means the hairless sepal, and there is hair on the dorsal sepal of this plant, The only species in the section Uncifera that I know of with hair on the dorsal sepal is P ancistra from Ecuador, I am working to find out if the location of this plant can be ascertained. It also would not be the first time that an Ecuadorian species ended up in Costa Rica or vice versa without Panama and Colombia.
