Pennilabium struthio Carr 1930 Another Flower Photo by Nitade Chula

Part shade Hot Warm Summer

Common Name The Ostrich-Like Pennilabium

Flower Size 1" [2.5 cm]

Found in the eastern Himalayas?, Thailand, Malaysia and Borneo? in riverine hill forests at elevations around 500 meters as a miniature sized, hot to warm growing epiphyte with a short stem carrying a few close set, elliptical, unequally bilobed apically, often twisted at the base leaves that blooms in the summer on a short to .4" [1 cm] long, unbranched, flattened, successively 1 to 2, few flowered inflorescence.

CAUTION From what I can gather from the scant information that there is, the difference between this species and P proboscidium is this one does not have hirsute apices of the petals and P proboscidium does, and in this species the rostellum is not readily visible as it is hidden by the entrance to the spur and the squared of apices to the lip otherwise they are very similar.
