Lower Guinea. Angola, Dr. Welwitsch. 



Cultivated under the names of Sobbeure, Ater, and Schimbera. 



4. L. animus, Linn. ; DC. Prod. ii. 373. A slender diffuse glabrous 

 annual with stems narrowly winged upwards. Leaves with a single 

 pair of linear or linear-lanceolate leaflets. Flowers 1-3 together on 

 elongated axillary peduncles. Calyx glabrous, \ in. long, the teeth 

 lanceolate-acuminate. Corolla yellow, more than twice the calyx. Pod 

 linear, 2-2J in. long, 5-6 lines broad, channelled down the upper suture

Nile Land. Abyssinia (teste Schweinfurth !) 



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 Karague by 

 Speke and Grant. P. abyssinicum, desciibed by Dr. A. Braun, in the Flora for 1841, 

 p. 269, also cultivated in Abyssinia, does not appear to differ from the latter materially.
