UOLBOPHYLLUM. 



auclum, nunc inappendiculatum. Columna naua, semiteres, rautica, 

 basi in pedem producla. Stigma fovea sub rostello excavata. Pollinia 

 4, collateralia, 00 00, subaequalia, cereacea, omnino libera. Anthera 

 2-locularis. 



Herbae epiphytae, Asiae tropicae , pseudobulbosae. Foiia solitaria, coriacea. Fiores 

 soiitarii vel pauci . conspicui , pedunculis radicalibus. 



A genus intermodiate betwcen Dendrobium and Bolbophyllum , having the large 

 llowers of the former , and ihe peculiar creeping habit of ihe latter. The species 

 agree with Dendrobium in having four nearly equal pollen- masscs , and a hornless 

 coiumn; but they have coriaceous, not thin half-transparent llowers , and a toiigh 

 leathery lip , enlarged not contracted at the base. If they had a cauilicie and gland 

 to their pollen-masses , they wouid almost be Asiatic Waxillarias. Tfaeir aowers form 

 neither horn nor spur . but are simply inflated and expanded at ihe base of the sepals. 

 One of them has been published by Dr. Blume as an Ephippium , a group which he 

 now regards as a mere form of Bolbophyllum. That generic name uannoi be con- 

 veniently applied hare ; because all the oiher species formerly collected under il be- 

 long either to Bolbophyllura , or Girrhopetalum , or to some Vandoous racc , for 

 which aione, if it proves herefter to be disiinct , should the name Ephippium be 

 retained.
