Species 30. Indian, Malayan and Australian. 



Li some descriptions of tlie species of this genus the column foot 

 lias been taken for the claw of the lip, and tlie spur which is cu- 

 riously pushed forward and horizontal or upcurved taken for the 

 midlobe, this organ being taken for a callus, but it is I think quite 

 clear as to the so-called Heshy midlobe of the lip being really the spur. 

 'J'he genus Ornithanum , Lindl. restored by King in the Ann. Bot. 

 (Jard. Calc, I would keep under Sairochihti^. It chiefly differs in 

 tlie complete suppression of the midlobe, and even of the side lobes.
