ORCHIDACILE 



about 2 mm. long, triangular, subacute, arising just above the 

 base of the column, exceeding the rostellum. 



Mature pseudobulbs are wanting in the material from which 

 the description was made. D. crassifolium is most closely related 

 to £). kamborangense Ames, from which it differs in the obtuse 

 leathery leaves, in the lateral and middle lobes of the lip, and in 

 the appendages of the column. D. perspicabile is also nearly 

 related, but sufficiently distinct in the lobing of the Up. (Plate 

 84.)

6. Dendrochilum Dewindtianum W. W. Sm. in Notes Bot. 

 Gard. Edinb. 8 (1915)321. 



This species is referred to Pfitzer's series Dilatata. The labellum 



suggests D. longifolium Reichb. f. In the original description the 



specific name is spelled Dewindtiana, presumably because the 



species was dedicated to the Ranee of Sarawak, but as the specific 



name is an adjective, it must agree with the generic name.
