Grammatophyllum.~\ CXLVIII. ORCHIDE^. (J. D. Hooker.) 19 



straight nerves and two linear ridges between the side lobes. I cannot find 

 characters whereby to distinguish G. fastuosum & macranthum ; the latter was 

 founded on Griffith's specimens. The flowers vary much in size, and the sepals and 

 petals of the Perak plant are narrower than in the others. 



44. DIFODXUXK, Brown. , 



Stems leafy, tnfted and epiphytic in the Indian species (terrestrial and 

 leafless in Australian). Leaves coriaceous, jointed on their sheaths, equitant. 

 Racemes long-peduncled, flowers rather large; perianth of Grammatophyllum, 

 but with the base of the lip forming a small sac with the column, and 

 the side lobes reduced to small teeth ; pollinia separately stipitate on a 

 globose gland. Spepies 6, Australian, Malayan and Pacific.
