ORCHIDACE.E 



cally ciliolate, one- or indistinctly three-nerved. Petals about 

 3.2 mm. long, 1 mm. broad, linear-oblong, acute or subacute, 

 one-nerved, somewhat thickened and microscopically ciUolate on 

 the upper half. Lip minutely clawed, in natural position gently 

 decurved near the middle with the sides of the lower portion 

 erect and conduplicate, the central margins on each side sharply 

 revolute ; limb when expanded narrowly deltoid, acute, about 

 4.55 mm. long, 2.6 mm. wide near the base, with a pair of small 

 approximate calli at the base, the central margins on each side 

 microscopically ciliate. Column inconspicuous, provided above 

 with a pair of sharply triangular arms and below with a promi- 

 nent foot bearing midway a minute porrect tubercle. 



This plant has numerous more or less near allies. It is distin- 

 guished from Bulbophyllum obtusipetalum J. J. Sm. by smaller 

 sepals, larger petals of different shape and a lip which is nearly 

 twice as large, and from B. gibbosiun Lindl. by markedly smaller 

 sepals and more fleshy flowers, \\'ith a dissimilar tubercle on 

 the column foot. B. deltoideum differs from B. unguiculatum 

 Reichb. f. in its much larger petals and lip. IMinute bracts, long 

 inflorescences and ovate petals characterize B. saccatum Kranzl. 

 The Philippine allies, B. dasypetalum Rolfe ex Ames, B. Escri- 

 torii Ames and B. ma?'ivele?2se Ames, lack the proportionately 

 large lip of this species. B. ebulbe Scliitr. has shorter leaves and 

 petiole and apparently smaller perianth than B. deltoideum.
