Common Name The Physurus-Like Leaved Psilochilus [Physurus is an orchid genus]
Flower Size
Found in Grenada, Trinidad & Tobago, Costa Rica, Panama, Venezuela and Guyana at elevations around 1200 to 1400 meters as a medium sized, cool growing terrestrial with a 3 to 4, narrowly elliptic to lanceolate-elliptic, acuminate, shortly petiolate base leaves that blooms in the later summer and mid fall on a terminal, .8 to 2.8" " [2 to 7 cm] long, several flowered inflorescence carrying pale green flowers with a purple suffused lip.
"The lip shape of this species varies among populations––in some the lateral lobes are short, reaching about 1/3 of the middle lobe length, other are characterized by the lateral lobes extending almost to the middle part of the middle lobe. All representatives of P. physurifolius have lip with conspicuous claw and distinctly petiolate leaves. The distinction of this species from similar P. modestus based on the ovate to elliptic, apically obtuse or shortly acute leaves observed in this species. In P. physurifolius the leaves are acuminate, more elongate than in P. modestus."
