ORCHIDACE^E 



D. Aclinia Reichb. f. in Bonpl. 4 : 329. To this interesting spe- 

 cies I refer specimens from Luzon. D. pseudaclinia is anomalous 

 among Dendrobiums. It belongs to a group of about four species, 

 which agree in detail with Griffith's Aclinia. The sepals, petals, 

 and labellum are similar, about 1.2 cm. long by 2-3 mm. wide. 

 There is no mentum. The stout column is quadridentate, the 

 posterior tooth bearing the anther, the anterior one arising from 

 the region of the rostellum. In dried specimens the flowers are 

 yellow and are described as yellow by the collector. The stems 

 are slender, somewhat fractiflexed, concealed in dried specimens 

 by loose, scarious sheaths (leaf bases). The flowers are borne in 

 twos or threes on the leafless stems. The leaves are subcoria- 

 ceous, distichous, oblong, acute, tapering at both ends, about 

 6 cm. long by 1 cm. wide. 



A cultivated specimen under observation at Manila failed to 

 expand its flowers. Mr. Merrill of the Bureau of Science described 

 this specimen as follows : " Calyx i.e. pedicel and ovary green, 

 corolla straw colored. Have seen no open flowers in the two 

 months the specimen was in flower. It may open at night or very 

 early in the morning, or possibly does not open at all. Flowers 

 from leafless branches, usually two, each with long pedicel on a 

 very short common pedicel." 



Reichenbach informed Lindley that he had seen specimens 



from Manila.
