This species is allied to C. lateriflorus Baker in its lateral inflor- 

 escence which is unusual in the genus. It differs from that species

 the field-notes the bracts are bright transparent pink, paler, almost 

 white, at the base ; the corolla white, with bright yellow in the 

 mouth of the lip. 



Halopegia azurea K. Schum. There ai'e a number of 

 specimens and three sketches of Halopegia which differ somewhat 

 in appearance. We have first the typical form, in which the 

 flower spikes are still enclosed in the sheath of the subtending
