Description: — A slender diffusely branched subscandent perennial, 
glabrous on the branches, leaves and peduncles ; stem short, thick ; 
branches terete, woody at the base, sometimes almost leafless. Leaves 
from a few lines to 2 inches long by J — 3| lines broad, narrowly linear 
to linear-oblong or lanceolate, saggittate or hastate or sometimes cuneate 
or rounded at the base, entire, acute, rarely obtuse ; petiole 1 — 6 lines 
long, sometimes tendril-like. 
Flowers distant, axillary; peduncles 5 — 8 lines long. Calyx 2 lines 
long, glabrous or glandular-pubescent ; segments lanceolate, acute or 
acuminate, more or less scarious on the margins. Corolla (including the 
spur) 9 — 10 lines long (1^ inches according to J. D. Hooker 1. c.), 
yellow, pilose outside ; palate clothed with long citron-yellow hairs ; spur 
about ^ inch long. Filaments densely pilose. 
Capsule shorter than the calyx, globose, glabrous. Seeds reniform,. 
tuberculate. 
Locality : — Aden (Defl.). 
Distribution : — Canary Islands, N. Africa, Nubia, Eritrea, Abyssinia,. 
Somaliland, Arabia. 
Note : — This species has been included on the authority of Defiers.. 
From the above description it is evident that L . sagittata is very variable 
in habit, shape and size of the leaves, and the length of the peduncles. 
Hemsley and Skan found that many of the specimens cited by them in 
the ‘ Flora of tropical Africa ' (vol. IV, part 2, p. 291 ) had been named L. 
maeilenta Dene, instead of L. sagittata Hook. f. L. macilenta is different 
in habit, has much shorter peduncles, minute flowers, and much smaller 
capsules. 
2 , Schweinfurthia A. Braun. 
Annual or perennial diffuse glabrous and glaucous herbs. Leaves 
usually alternate, quite entire.
