ORCHIDACE^E 

 totum labellum 1 cm. longum, 1 cm. latum. Gynostemium sec- 

 tionis. 



In general habit Dendrobium Escritorii resembles D. chryso- 

 tainium Schltr. from Celebes, but the stems are not swollen at 

 base. D. chrysotainium, aside from the equitant leaves, agrees with 

 the species of § Rhopalanthe. The labellum is very obscurely 

 trilobed. In several flowers examined the lobing was obsolete, 

 the general outline of the labellum being cuneate-flabellate. The 

 divisions of the fringed margin are about 1 mm. long.
