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 fluffy hairs; lobes 4-4 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 ciliate with similar hairs of a darker 
purple. Outer coronal-lobes } lin. long, forming 5 small pockets, 
slightly sinuate or subtruncate at the margin, glabrous, whitish ; inner 
coronal-lobes almost ¢ 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, 1 have not dissected, 
but externally they seem identical with those of Carson’s plant. C. mozambicensis 
may prove to be identical with C. dentieulata, 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.

40, #. Stem twining, glabrous. Leaves subsessile or shortly petiolate, 
1} in. long, 7-8 lin. broad, fleshy, ovate or subrhomboidal, acute at both 
ends, denticulate at the apex. Peduncle moderately long, 2-flowered ; 
bracts, bracteoles and sepals filiform-subulate. Corolla about 20 lin. 
long, whitish, spotted with fuscous, glabrous outside; tube 15 lin. long, 
moderately inflated in the lower part; mouth dilated, broadly funnel- 
shaped, 9-10 lin. in diam., ciliate; lobes 5 lin. long, linear, erect, con- 
nate at the tips, pubescent, ciliate with long vibratile clavate hairs.—

Mozamb. Dist. German Eagi Africa: Silai, Holst, 3583. 
I have not seen this species, but it would appear to be allied to and may prove to- 
be the same as C. mozambicensis, Schlechter, The dimensions of the flower are 
taken from the figures quoted.

twining, about 1 lin. thick, glabrous. Leaves glabrous on both sides, 
apparently fleshy; petiole 3-44 (or more) lin. long; blade 6-8 lin. 
long, 5-6 lin. broad, ovate, acute, apiculate, cordate or subcordate at 
the base. Peduncles lateral at the nodes, 14-3? in. long, with 2-3 
distant pairs or clusters of 3—4 flowers racemosely scattered along them, 
glabrous ; pedicels 3-4 lin. long, glabrous. Sepals 1} lin. long, lanceo- 
late, acuminate, glabrous. Corolla about 11 Jin. long in the dried state ;
