This is most nearly allied to C. Jacquemontiana, which is now before 
me. It differs from that species in the shape, colour, and relative 
proportions of the tube and limb of the corolla, the segments of 
which, in C. Jacquemontiana, are broader upwards, and entirely green, 
much larger than in the present species, and the flowers far more 
numerous. The leaves are similar to those of C. Jacquemontiana, but 
are never softly tomentose, as in that plant. The exterior lobes of the 
corona in C. ophiocephala are united nearly to their summits.
