﻿A small irregularly spreading glabrous herb, with rather fleshy 

 shoots 4-10 in. long. The scattered leaves are smaller near the 

 base of the shoot, and lanceolate to elliptic in shape, while above 

 they are much larger and oval-oblong; their size varies from 

 li to 31 in. in length, and from less than \ in. to If in. in breadth; 

 the thick stalks are about one-fourth the length of the blade. The 

 flowers are sometimes solitary on short axillary peduncles, or borne in 

 a simple axillary dichasium, but the greater number on a many-(to 10) 

 flowered spreading cymose inflorescence springing from the base of 

 the shoot. The sepals closely resemble those of /. Protect, in character, 

 but are more generally and deeply coloured and somewhat narrower, 

 with an acuminate rolled-up falcate tip ; the corolla is apparently 

 between bell- and funnel-shaped, but was only present in a withered 

 or unopened state ; it is about If in. long, with a tube of 1^ in. long. 

 The stamens, which are of three lengths, closely resemble those of 

 /. Protra, and are fixed to the tube about 3 lines from its base. The 

 hairs, as in the last and other species, on and about the triangular base 

 of the stamen are very long, capitate, and glandular, the head being 

 oblong and remarkably large. They may perhaps function as pollen 

 collectors. The thin-walled capsule is globose, glabrous, except for 

 a few scattered hairs on the up 

 brown tinged above with purpl 



Nearly allied to /. Protect, though different in habit, and in its 

 perfectly glabrous character. Is apparently near I. Vogelii Baker 

 (ex descriptione brevi) in Keiv Bulletin, 1894, p. 71, but the leaves 

 are not broadly ovate, obtuse, and cordate ; moreover, the flowers 

 of I. Vogelii are described as "omnino I. asarifolia," whereas in our 

 species the sepals are acuminate, not very blunt, as in asarifolia. 



Ipomoea humifera Rendle et Britten, sp. n. " Herba ut videtur 

 perennis humifera nec scandens," caule tenuissimo repente hirtulo, 

 ramos longos tenuissimos glabros emittente; foliis ovato-cordatis 

 (interdum angustioribus), acuminatis, membranaceis, rigidulis, mar- 

 gine hirtulo et petiolo brevi patule-piloso exceptis glabris ; floribus 

 axillaribus solitariis, pedunculis subrigidis, glabris, folia baud 

 lequantibus ; bracteis minimis subulatis ; sepalis parvis subaequali- 

 bus glabris, ovatis mucronatis, 3 exterioribus dorso verrucosis; 

 corolla speciosa purpurea, late tubuloso-mfundibuliformi ; staminibus 

 inaequalibus filamentis linearibus a basi latiori longe pilosa tubo 

 affixis, antheris sagittatis; stylo filiformi, stigmate capitato globoso. 



Hab. In dumetis sylvestribus de Mata de Pungo, Pungo An- 

 dongo; fl. medio April, 1857, Welwitsch, No. 6177, et Quitage, 

 Waldchen ober Quibinda, P. Andongo, No. 6178. 



Has a very thin creeping stem sending out long wiry branching 

 shoots, which may be over 5 ft. in length, apparently spreading 

 over the ground and twining round low plants, as they are much 

 twisted and bent, while the almost filiform terminal portion has 

 become looped and twined closely round the portion immediately 

 below ; according to Welwitsch's note, " humifera nec scandens." 

 The leaves vary in size from about 1 in. long by £ in. broad on the 

 main stem and shorter branches, to 2-2£ in. long and 1-1} in.
