In the Flora Capensis, iv. ii. 67, this specimen is regarded as a yellow-flowered 
variety of J. palmata, but it differs in the saccate calyx as well as in the colour of 
the flower. The South African specimen is probably not conspecific, the corolla is 
only 14 in. long, and apparently white ; it seems also to be a smaller-leaved plant. 
102. I. calearata, V. £. Br. Stem twining }~1 lin. thick, sparsely 
covered with minute tubercles. Leaves glabrous, doubly tripartite, 
primary divisions stalked, secondary lanceolate, acute, tapering at the 
base, median segment 1}—21 in. long, }—? in. broad, the others gradually 
smaller; petiole 3-14 in. long ; pseudostipulate by the development of 
a pair of axillary palmatisect leaves. Peduncles 3-1 in. long, 1-flowered, 
glabrous, bearing at the middle a pair of subulate bracteoles ? lin. long. 
Sepals elliptic-oblong, very obtuse, glabrous, 5 lin. long and half as 
broad, two of the outer sagittately bicalearate at the base, the third 
with one spur and the two inner without spurs. Corolla funnel-shaped, 
glabrous, 13-2 in. long, with limb of equal diameter, light yellow or 
delicate satiron-coloured marked with light violet in the throat of 
the tube. ‘Flower opens with sunrise and rapidly closes.” Fruit 
unknown.

Evidently very closely allied to, perhaps inseparable from, J. dasysperma, 
Jacq., which we know only from the figure. Jacquin, however, does not show the 
quasi-stipular development which gives a characteristic appearance to the leaves. The 
corolla-tube is slightly longer, and the calyx more markedly gibbous in the plants 
which Mr. Brown has described.—A. B. R. 
103. I. saceata, Hallier f.in Engl. Jahrb. xxviii. 48. A perennial 
herb. Stems twining, glabrous, terete, rubescent, rough with raised 
points, as are the peduncles and pedicels. Leaves about 2# in. long by 
34 in. broad, biternately pedate, with lanceolate acute mucronate lobes ; 
petiole 14 in. long, thin, sparsely muriculate. Peduncles axillary, 
robust, longer than the petiole, up to 2? in.; flowers many, corymbose ; 
pedicels 4-1 in. long. Calyx 5 lin. long. Sepals subcoriaceous, 
brownish with a pale membranous edge, roundish-elliptic, obtuse, the 
two outer gibbous and fimbriate on both sides at the base, sometimes 
almost spurred. Corolla showy, 24 in. long, tubular-campanulate; 
limbs wide spreading, violet in the lower part, yellow in the upp 
Capsule glabrous, globose, about 5 lin. in diam. Seeds trigonouss 
velvety and with long yellowish hairs on the angles.

104. I. odontosepala, Baker in Kew Bulletin, 1894, 73. Habit 
apparently of J. palmata. Leaves thin, glabrous, orbicular in gene 
outline, 14-2 in. in diam., deeply divided into 5 lanceolate to oblanct 
late, acute segments, the outer pair forked; petiole very slender, about 
as long as the blade. Calyx glabrous, 4 lin. long; sepals coriaceous,
