apex, erect, 2.5 to 2.6 cm long, 2.5 to 3 mm wide. Labellum 
somewhat fleshy, trilobed, about 2.5 cm long; lateral lobes rather 
short, subquadrate, the apex broadly obtuse or rounded, free 
portion about 3 mm long; middle lobe suborbicular, about 1.5 
cm long, 1.5 cm wide, apex subrounded with a minute apicule, 
the margin undulate; disc with 5 low keels at the base, two of 
the keels increasingly high, conspicuous and wavy toward the 
apex, extended to one-third or one-half of the middle lobe; the 
3 short basal keels 3 to 3.5 mm long. Column about 1.8 cm 
long, arcuate, fleshy, conspicuously winged at the apex. 
Luzon, Manila, cultivated in the gardens of Mrs. Remedios C. 
Gonzales, Bur. Sci. 82232 Quisumbing, February 24, 1931. The 
plants flowered again a month earlier in Mrs. Gonzales’s gardens 
this year (1932). The living plants, purchased from a peddler, 
were of uncertain origin but they were surely Philippine. The 
sepals are sea-foam yellow and deep sea-foam green at the mid¬ 
dle ; the petals are sea-foam green; column glass green, the apical 
margin pale grass green; the labellum marguerite yellow except 
the lamellae, lateral lobes and the markings at the center of the 
middle lobe snuff brown. 1 
Among the known Philippine coelogynes, this species appears 
most closely related to C. marmorata Reichb. f., but differs in 
its longer scape and in the keels of the lip. In habit it suggests 
C. bilamellata Lindl., C. candoonensis Ames and C. longirachis 
Ames, but it has much larger flowers and a; dissimilar lip.
