Common Name or Meaning The Full of Caterpillars Pleurothallis [refers to the appearence of the pubescent flowers within the revolute leaf]
Flower Size .4" [1 cm]
Found in Colombia without locational data as a small sized, caespitose epiphyte with stout, erect ramicauls enveloped by a long, loose, tubular sheath below the middle and 2 to 3 others at the base and carrying a single, apical, erect, coricaeous, broadly elliptical, rigidly convex, revolute margins, shortly acute and decurved apically, mottled with purple within, rounded and abruptly contracted below into the petiolate base leaf that blooms in the winter and spring on a slender, arising on the back of the leaf and subtended by a spathe with an annulus from below the apex of the ramicaul, erect, congested, distichous, .8" [2 cm] long, simultaneously several flowered inflorescence with less than half as long as the pedicel floral bracts.
"Obviously related to P imraei but vegetatively the large, egg-shaped leaf is distinct with the markedly convex dorsal surface. Consequently it is deeply concave on the other side where the racemes are borne wwithin the cavity at the base of a distinct, stout petiole. It appears as if some fuzzy catepillars hadd entrnched themselves within a rolled up leaf, a sight familiar to some of us. The sepals are covered by a dense, long villous, white pubescence within. teh petals are spathulate and truncate. and narrowly unguiculate on the lower half and the arcuate llip is denticulate and verrucous at the apex. It has a similar pair of calli on the disc." Luer 2000
