(transversely oblong may be intended) in outline above, irregularly 
erenulate, slightly 4—6-grooved on the back ; inner corona-lobes 
ligulate, porrectly incurved above the anthers, intricately excavated

This is evidently closely allied to C. lutea, N. E. Br. The colour of the 
flowers is not stated, but from the specific name it should be blackish or dark 
purple-brown.

stems decumbent, about 1} in. long and 5 lin. thick, obscurely 
6-angled or with obscurely 6-seriate tubercles ; flowers solitary or 
rarely in pairs; pedicels 4-5 lin. long, stout, glabrous ; sepals | lin. 
long, triangular-lanceolate, very acute, glabrous ; corolla campanulate, 
with a short tube, green; lobes erectly-spreading, } in. long, linear- 
lanceolate, flat, somewhat hooked at the obtuse apex, glabrous on 
the back, densely pilose on the inner face; outer corona white, 
shortly cup-shaped, 5-sulcate, with free subdivaricate lobes, shortly 
notched at the truncate apex ; inner corona-lobes shorter than the
