somewhat leafy outer sepals, the margins of the bracts and sepals, 

 and the veining on the back of the leaves. The small leaves are 

 £-f in. long, 3-4 lines broad, borne on a petiole 1 line in length. 

 The narrow bracts are about £ in. long, the larger outer sepals 

 4|-6 lines, and 8-4 lines broad. The corollas in the specimen had 

 either withered and fallen, or had not quite opened ; the latter were 

 13-15 lines long, and had apparently been of a rosy colour. The 

 anthers were nearly 2 lines long, the filaments attached by a broad 

 triangular hairy base 1 line from the base of the corolla-tube. The 

 capitate stigma was bilobed by an apical depression ; the ovary 

 bilocular and 2- seeded. In the unopened flower the stigma was on 

 a level between the shorter and longer stamens, the anthers of all 

 of which had thoroughly dehisced, while the stigmatic papillae were 

 covered with pollen. On opening a bud only \ in. long, all the 

 anthers were found more or less in a state of dehiscence, though 

 the stigma, which was here above them, was clean. These facts, 

 which were also observed in other species, suggest self -fertilisation. 



Approaches the South and Tropical African calystegioides 

 E. Mey., but easily distinguished by its shorter and in proportion 

 broader leaves, and smaller bracts and sepals.

Welwitsch's notes contain a somewhat full description of this 

 plant, of which we have two sheets in the British Museum. On 

 neither is there any flower, so that in the description of corolla 

 and stamens we have followed the collector's MS. The spreading 

 branches exceed 1^ ft. in length ; the leaves vary from 1-J to 2 in. 

 in length, and from f to 2 in. in width at the open broad cordate 

 base; the petioles sometimes equal the blade in length, but may 

 reach a length of 4 in. The short (^-f in.) robust axilla i v )>.■, lunch's 

 are borne in pairs, and are recurved in the fruit. The eaivx in the 

 fruiting stage is hispid and^verrucose ; the large dull greyish seeds 



As pointed out by Mr. Britten (p. 86), this plant cannot, as 

 Hallier suggests, be identified with Ipomoea hispid* R. & S. It 

 resembles this species in the character of its leaves, which are, 

 however, more broadly cordate, but is distinguished by the paired 

 flower-peduncles, never crowded as in /. hispida, its rather more
