4. L. annuus, Linn.; DC. Prod. ii. 373. A slender diffuse glabrous 
annual with stems narrowly winged upwards. Leaves with a single

elongated axillary peduncles. Calyx glabrous, 1 in. long, the teeth 
lanceolate-acuminate. Corolla yellow, more than twice the calyx. P od 
linear, 2-24 in. long, 5—6 lines broad, channelled down the upper suture 
but not winged, 6—9-seeded.

Pisum sativum and arvense are both cultivated in Abyssinia, and we have examples 
of the former from Angola, and brought from an elevation of 4-5000 ft. at Karagué by 
Speke and Grant. P. abyssinicum, described by Dr. A. Braun, in the Flora for 1841, 
p- 269, also cultivated in Abyssinia, does not appear to differ from the latter materially.
