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.
