Strophanthus gratus (Apocynaceae ) , 47217. From 
Southern Provinces, Nigeria. Seeds presented by Mr. 
A. H. Klrby, Asst. Director of Agriculture, Ibadan. 
A handsome flowering plant; it may be propagated by 
seeds which are distinguished from the Strophanthus 
seeds of commerce (S.kombe) by being glabrous. The 
seeds of this species are recommended for use in 
medicine, in preference to those of any other, chiefly 
because they yield crystalline strophanthin, whereas 
the established official Strophanthus yields this 
glucoside in an amorphous condition. Used for poison- 
ing arrows. (Adapted from Kew Bulletin, Useful Plants 
of Nigeria, Part 3, p. 447.) 
Strophanthus hispidus (Apocynaceae), 47218. From 
Southern Provinces, Nigeria. Seeds presented by Mr. 
A. H. Kirby, Asst. Director of Agriculture, Ibadan. 
"The seeds are an important drug, worth about 2s. 
to 2s. 6d. (approximately 50 to 60 cents) per pound 
wholesale, commonly shipped in the pods, but more often 
taken out, freed from the awns and packed in bales. 
The seeds are poisonous, the active principle being 
strophanthin; used in Nigeria and generally in tropi- 
cal Africa for arrow poison. It may be propagated by 
seed, but the commercial supply is obtained, so far, 
from wild plants ,- strong fibers making the seed diffi- 
cult to collect, though, according to Dalziel, as a 
shrub with long lax branches it is capable of being 
grown in the neighborhood of towns and villages. The 
seed pods are available in October at Abepa, Kabba 
Province, where the plant is said to be plentiful. 
The seeds take several months to ripen. Blllington 
reports collecting in October a pod then not quite 
ripe, after noting its development for ten months."

"This tropical African tree flowers in the months of 
June, July, and August, and usually produces a number 
of oblong or oval berries which resemble olives; they 
are dull green at first but gradually change, as they 
ripen, into a dusky red. The seeds are enclosed in a 
thin, soft, slightly saccharine pulp which, when
