well in other respects, and I was assured by the late Mr. Cunningham that 
this is really the species intended in the Prodromus. I fear it it is hardly 
distinct from C. Patersoni. Sepals and petals yellowish green, with 
brown purple glands. Lip deep purple above the middle.

A smaller plant than C. filamentosa. Flowers apparently of the same 
colour. Can it be a hybrid between C. dilatata and filamentosa ?

Flowers pale green with a purple rib along the sepals and petals which 
are nearly smooth, sometimes clavate and sometimes setaceous at the 
point ; lip green with purple glands and sometimes with a purple apex.

Flowers pale greenish yellow with’ purple brown glands. Lip of the 
same colour, but with purple glands and toothings. Mr. Gunn, who has 
sent me numerous specimens, says that this flowers immediately after 
C. pallida, and is succeeded by C. filumentosa. 
The var. 3 is a more dwarf plant, with larger flowers, shorter and 
broader sepals, more hairy leaves, and the disk of the lip below the apex 
manifestly tuberculated. In this latter respect C. Patersoni is very variable, 
some specimens having no tubercles at all. I also find the number of 
rows of glands along the lip uncertain, sometimes 4 sometimes 6.
