‘The natives apply the oil for itch; or, if a village is infested with this, they take four of its leaves, place 
flour in each leaf, and this preparation is put by the pathways leading into the village.—J. А. G.]

[An erect shrub, in flower during February and March in the water-runs at Karagué. Leaves 
alternate and rather close together, with numerous minute white flowers in the axils of the leaves.

Hab. Mininga, 4° 18' 8. lat., Col. Grant! Widely cultivated in the tropics. 
[Grows as far as 4° 18! S. lat., but rarely seen to the north of this. The tuber of this useful plant is 
called “mhogo.” The natives say there are several varieties of it; some kinds eat best raw, others 
boiled, fried, roasted, or made into flour. It grows to 10 feet high, and, as a foliage-plant, would 
succeed in this country as well as the castor-oil plant; for they grow in the same soil and climate. 
The natives propagate it from cuttings placed on ridges 4 feet apart. Seed-vessel three-celled, with 
six ridges outside, tipped with a coral-coloured plume, and based in a circle of red. Тһе flower and fruit 
are insignificant in comparison with the size of the plant; and the varieties which flower are most in 
esteem with the natives. Тһе poorer classes of Zanzibar live entirely on this tuber and dried shark from 
the Persian Gulf.—J. A. G.]

Hab. Madi, Jan. 1863, Col. Grant! 
[Not а common plant. Collected in January near the burn at Madi. A foot high, and in fruit. 
The root was firm in the ground, and was not reached. Leaves alternate, single, tripartite, with 
shining surfaces and downy beneath. On cutting the stem а gummy yellow colouring-matter exudes 
pleutifully ; and this becomes glazed on paper. "The seed-vessel (now unripe) is about 2 inch long and 4 
inch in diameter, slightly pubescent, with three rounded divisions apparent on its surface, three-celled and 
seeded ; the seeds are with difficulty cut through. The calyx adheres to the seed-vessel, and consists of 
five green sepals with five smaller withered petals (2) intervening. 1 called it the gamboge-plant; but 
the natives could not tell me its use or property.—J. A. G.] i
