Hot LATE SummerEARLYFall

Common Name or Meaning Lawesson's Platystele [American Discoverer of species current]

Flower Size .24" [6 mm]

Found in Napo province of Ecuador in tropical rainforests at elevations around 260 to 350 meters as a mini-miniature sized, hot growing epiphyte with slender, erect, ramicauls enveloped by 2 to 3, thin, tubular sheaths and carrying a single, apical, erect coriaceous, narrowly oblanceoalte, subacute to obtuse leaf that is narrowly cuneate below into the long-petiolate base and blooms in the late summer and early fall on an erect, subcongested, subsecund, filiform, 1 to 1.48" [2.5 to 3.7 cm] long including the .8 to 1.2" [2 to 3 cm] long peduncle, successively few flowered inflorescence arising laterally from the ramicaul with thin floral bracts.

"This very small species occurs in the lowlands of eastern Ecuador, where it has been collected but once to my knowledge. The habit with narrowly elliptical leaves is not distinctive except for the very small size. The hairlike peduncle, between .8 to 1.2" [20 and 30 mm] long, bears a tiny, subsecund raceme no longer than .28" [seven millimeters]. Capsules seem to be readily formed. The minute flowers are among the smallest of the genus, the ovate, concave sepals being no more than .024" [0.6 mm] long. The petals are smaller and subacute. No veins are visible in either the sepals or petals, but the cells are easily visible with strong magnification. The lip, slightly larger than the lateral sepals, is coarsely cellular-verrucose."
