Creeping on the ground ; flowers white. 
Ipomoea kwebensis, N. L. Br. Caulis longissime volubilis, glaber. 
Folia petiolata, ad basin palmatisecta, 5-7-loba, glabra, lobis lanceo- 
latis acutis. Pedunculi breves, 1-3-flori, glabri. epala ovata, 
purpurea, glabra. Semina dense velutino-pubescentia. I. guingue- 
Solia, var. purpurea, Hallier f. in Bull. Herb. Boiss, vi. 546. 
xlabrous in all parts, with the exception of the seeds. Stem 
quite a different geographical area, that I cannot follow Hallier in 
considering it to be a variety of I. guinguefolia, Hochst. The latter 
is an annual, with short prostrate stems that show no tendency to 
twine, gland-tuberculate petioles, white flowers, and has hitherto 
only been found in Abyssinia. I. guinguefolia, var. pubescens, of the 
ora Capensis is entirely different in foliage and calyx from the 
Abyssinian plant as well as from I. kwebensis. 
Ipomoea verecunda, V.£. Br. Caulis prostratus, tenuiter puberulus. 
Folia petiolata, palmatim 7-9-loba, supra glabra, subtus parce pube- 
scentia ; lobi lineari-oblongi, anguste oblongo-lanceolati vel obovato- 
spathulati, acuti vel obtusi, apiculati, basi angustati. Peduncul 
1-flori, prope apicem bibracteolati. Sepala late ovata, obtusa vel 
subacuta, pubescentia, atropurpureo-nervosa. Corolla quam calyx 
paullo longior, 1-8 cm, diametro, alba, tubo brunneo-purpureo, glabro.

tems procumbent, rather slender, very thinly puberulous. 
Leaves petiolate, 14-24 in. in diam., deeply palmately 7-9-lobed, 
glabrous above, thinly pubescent beneath and on the }~1 in. long 
petioles ; lobes 8-15 lin. long, 2-5 lin. broad, linear-oblong, 
narrowly oblong-lanceolate or spathulate-obovate, acute or obtuse,
