covered with long straight purple hairs, middle of the upper part 

 of the tube with a broad band of similar colourless hairs, constric- 

 tion of the inflated part with a ring of fluflfy hairs; lobes J-J in. 

 long and about the same in breadth at the base when flattened out, 

 connivent, connate at the tips, broadly deltoid-ovate, obtuse, apiculate, 

 replicate, with a broad keel down the face, bulging out and ter- 

 minating rather abruptly at its base, blackish -purple, with a greenish 

 or whitish ? transverse band at the middle, covered on the inner face 

 with long straight purple hairs and cilia te with similar hairs of a darker 

 purple. Outer coronal-lobes J lin. long, forming 5 small pockets, 

 slightly sinuate or subtruncate at the margin, glabrous, whitish ; inner 

 coronal-lobes almost J in. long, erect, linear-subulate, keeled behind at

I have not seen the Pungwe plant, and describe entirely from the specimens 

 collected by Carson & Taylor ; the flowers of the latter, however, I have not dissected, 

 but externally they seem identical with those of Carson's plant. C. inozavihicensi.t 

 may prove to be identical with C. denficulata, K. Schum., which was published a 

 month earlier, although Schumann neither describes nor figures the remarkable con- 

 striction at the middle of the inflated part of the corolla-tube.

 Ij in. long, 7-8 lin. broad, fleshy, ovate or subrhomboidal, acute at both 

 ends, denticulate at the apex. Peduncle moderately long, 2- flowered ;

 long, whitish, spotted with fuscous, glabrous outside; tube 15 lin. long, 

 moderately inflated in the lower part ; mouth dilated, broadly funnel-

I have not seen this species, but it would appear to be allied to and may prove to 

 b> the same as C. mozamhicensis, Schlechter. The dimensions of the flower are 

 taken from the figures quoted.
