77. I. simonsiana, Rendle in Journ. Bot. 1894, 178. An annual 
herb, branching just above the base. Stems long, diffuse, climbing, 
very slender, obscurely pubescent. Leaves thin, long-petioled, cordate- 
ovate, acuminate, coarsely dentate, 1-2 in. long and broad, sparsely 
pilose on both surfaces; petiole slender, generally shorter than the 
blade. Flowers solitary; peduncle 3 lin. long or less. Bracteoles 
minute, lanceolate ; pedicel stouter and longer than the peduncle, about 
6 lin. long. Sepals spathulate, apiculate, 3-nerved, glabrescent, lower 
portion subcoriaceous, broad upper portion herbaceous, 4} in. long, 
the inner longer than the outer. Corolla almost salver-shaped, under

Tne identification of Z. zambesiaca with I, lapathifolia rests on Hallier’s autho- 
rity. We have not seen the specimens collected by Stuhlmann on which Z. lapathi- 
Jfolia was based. Iam unable to follow Hallier in his later reduction of the species 
to a variety of J. hellebarda, which seems amply distinguished by its larger white 
corolla and velvety seeds.—A. B. R. 
79. I. humifera, Rendle d: Britten in Journ. Bot. 1894, 177. 
Perennial. Main stem trailing, slender, hairy ; branches long, very 
slender, glabrous, ultimately climbing. Leaves cordate-ovate, acum! 
nate, membranous, rigid, glabrous, except on the edge and petiole, 
those of the shoots 2-2} in.long. Flowers solitary ; peduncle glabrous, 
shorter than the leaves ; bracteoles minute, subulate. Sepals subequal, 
ovate, glabrous, 3 lin, long. Corolla between tubular and funnel-shaped, 
bright purple, 14-2 in. long.—Hiern in Cat. Afr. Pl. Welw. i. 79%-
