DIAGNOSES SPECIERUM NoVARUM. 239 
Mr Farrer rightly recognised the relationship of this Burmese 
plant to Kh. campylocarpum of the Himalayas, and the alliance 
is really very close. It seems to be an altogether smaller plant 
but like so many of these really representative species it offers 
barely strong characters for diagnosis. Points to note are its 
sticky buds, elliptic to suborbicular leaves, the persistent red 
hairs in the eit of bracts, calyx fleshy gidutir, corolla yellow 
3 cm. long, style ondatse at base. The plant to which Mr 
Farrer refers in the field-ticket attached to No. 1672 as Rh. 
eclecteum is Rh. atolosalpinx.
