Distrib. New Guinea (D.N.W., Mt. Morait, N. Coast, Beccari; Resi 
Riicken, Versteeg; Cyclops Mts., Gjellerup; D,S8.W., Hellwig Mts., von 
Roemer ; Mt. Carstensz, Kloss). 
This plant, wine-red in colour, was dotted about in little colonies, chiefly 
at the base of trees ; the erect stems, of equal height, were all horizontally 
inclined in one direction. The callosities at the base of the medium sepal 
are arranged as described for C. cordata Schtr. rather than as figured for 
C. ornata ; but this is possibly a varying feature, as in Kloss’s specimens 
they are not present at all.
