cordatum, 2:5 cm. longum, 2 mm. latum, lobis in utroque latere 2 acuminatis et 
cuspidatis complanatis, carina et cuspide atris, inter eus lobis 2 rotundatis erectis, 
sulco intermedio, costa mediana in lamina elevata. Columna 0:65 mm. longa, 
pede canaliculato, stigmatis fovea magna oblonga, stelidiis ovatis subacutis margine

Camp VI, 3100 ft., and Camp VI c, 3200 ft. 
Allied to and closely resembling in habit B. thrixspermiflorum, J. J. Sm., but 
differing in the much longer, quite differently-shaped lip, the acute cuspidate petals, and 
the remarkably long column, the longest I have seen in any species of the genus.

ad basin angustata, 5 mm. longa. Sepalum posticum lanceolatum, acuminatum, ad 
marginem ciliolatum, 1 cm. longum, 3 mm. latum, lateralia ovato-lanceolata, acuta, 
1:5 em. longa, 5 mm. lata. Petala ovata, 4 mm. longa, marginibus tenuibus, carina 
obscura carnosa in aristam producta. Ladellum 1 cm. longum, oblongum, cal- 
ceolatum, basi processubus corniformibus 2 parvis, callo intermedio parvo, apice: 
lanceolato carnoso obtuso 3 mm. longo. Columna parva, stelidiis longis filiformibus. 
Anthera apice conica, obtusa, ei P. papuane similis. 
Camps XIII to XIV, 10,500 to 12,500 ft. 
This species differs from P. papuana in the thicker, shorter coriaceous leaves, the 
acute sepals, and the longer, more oblong lip; from P. ciliolata, Schlechter, in its much 
larger pseudobulbs and leaves, and its much broader lateral sepals, which are nearly 
twice as wide as the dorsal one and not ciliolate.
