Flos pro sectione magnus. Sepala similia, longe caudata; 
lamina lanceolata. Petala lanceolata, acuta, tri- vel quin- 
quenervia. Labellum lineari-lanceolatum, basi biauricu- 
latum, obscure ciliatum. Columna generis, parva. 
EKpiphytic herb with a repent rhizome. Pseudobulbs 
eylindric-pyriform, suleate when dry, unifoliate, about 
1 cm. long and 0.5 cm. in diameter, mostly about 1-2 
em. apart on the rhizome. Leaves elliptic-lanceolate to 
narrowly elliptic-lanceolate, acute or somewhat obtuse, 
occasionally obscurely mucronate, 8.5—7 cm. long, 0.8— 
1.2 em. broad. Inflorescence 1-flowered; flower large for 
the subgenus; peduncle filiform, much exceeding the 
leaves, up to 15 em. long; bracts two, one subtending 
the flower and one near the base of the peduncle. Sepals 
similar, very long-caudate, about 40 mm. long; blade 
lanceolate, 4-to 5-nerved, about 14 mm. long and 3 mm. 
broad ; apex caudate, filiform, about 26 mm. long. Petals 
lanceolate, acute, 8-to 5-nerved, about 12 mm. long and 
3 mm. broad. Lip linear-lanceolate, 8-9 mm. long and 
about 1.5 mm. broad, biauriculate at the base; auricles 
rounded, erect, obscurely ciliate, about 1 mm. long. 
Column small, about 0.75 mm. long, with two aristate 
apical stelidia. 
Bulbophyllum caudatum is most closely allied to B. 
Bolsteri Ames from which it may be easily distinguished 
by the very long-caudate sepals and by the narrower and 
longer leaves, as well as by the several-nerved petals.
