19. Cypriprpium purpuratum. Lindl. in Bot. Reg. t. 1991. 
C. acaule, foliis coriaceis oblongis acutis striatis maculatis canaliculatis, 
scapo pubescente, sepalo dorsali acuminato ciliato margine revoluto, 
petalis oblongis subundulatis pubescentibus, stamine sterili lunato. 
Hab. in archipelago Malaico, hortulan. 
This rare plant is said to be a native of the Malay archipelago, but 
there is no evidence before me on that point. I have never seen it, but 
the excellent figure in the Botanical Register leaves no doubt of its being 
a quite distinct species. Its leaves are most like those of C. venustum, but 
are more oblong, and far less rigid, besides having a pallid colour, quite 
unlike that of the species alluded to; its petals moreover want the long 
bearded fringe, and the dorsal sepal is convex, not concave.
