Common Name The French Guiana Phragmipedium

Flower Size 4.2" [10.5 cm]

Found in French Guiana on trees at elevations of 80 to 500 meters as a small sized, hot growing epiphyte with a fan of 3 to 5, oblong-ligulate, conduplicate, overlapping, leathery, light green, margin entire leaves that blooms in the later fall on an erect, terminal, peduncle erect, cylindrical, slightly laterally compressed, green, pubescent, 2.52" [6.3 cm] long, provided with a green sterile bract, as long as to slightly longer than the leaves, to [24.5 cm] long overall, successively single, 2 flowered inflorescence with apex asymmetric; ovary green, tinged with burgundy to brown in variable proportions, cylindrical, pubescent, curved downwards at the top, shorter than the pedicel floral bracts.

"This new Phragmipedium is related to P caudatum and perhaps more to P humboldtii . However, it differs from them easily by its habit and especially by its much shorter petals (up to 4" [10 cm] versus 28" [70 cm] in P. caudatum and 32" [80 cm] in P humboldtii). Various floral details also separate it from these two species. Thus the flower is considerably smaller, the dorsal sepal is oblong lanceolate (versus lanceolate), the broadly oval synsepal (versus oval), the staminode rhombic (versus trilobate) and long-ciliated (versus glabrous or sparsely ciliate)."
