'The species, generally with the calyx and corolla-tube distinetly tomentose, is widely spread in Tropical 
Africa. "a а 
[A woody climber, named “ m'hoongo > (Kis.), found at Madi (December) іп a shady spot, by a rocky 
burn. Its trunk travelled like a boa constrictor along the ground till it found a tree to climb up, and was 
25 inches in circumference ; ascending to the topmost branches, it threw down pendants of foliage and 
clusters of lily-white scented flowers. The opposite leaves have surfaces like the soft green of our 
laurel; and their colourless midribs are sharp-angled underneath. The milk of this, if rubbed upon 
the skin, adheres like bird-lime, and can scarcely be rubbed off; while that of the “ m’peera,” another 
rubber, yields easily to water. The natives make this close distinction between the two, also that the 
leaves of the “ m'peera > are smaller. The juice of this is certainly very milky, but neither so sticky nor 
stringy as I should have supposed from the above description of two rubbers. The fresh young shoots 
are jointed every 10 inches, 1 inch in circumference, deep green, spotted, and round like india-rubber 
tubing ; they are brittle ; and a cord of pith may be pulled out of them. From these joints grow the 
tendrils by which the plant supports itself. 
Name and use.—The Wahiao people make playing-balls from the juice of this tree, and consider its 
rubber to be the most adhesive known. They know of another climber called the “ookombe” (Kis.), 
which is “brother to this; they also mention the “ m'peera;" but these are thought inferior.—

Hab. Karagué, Dec. 1861, Col. Grant ! 
[Size of an apple-tree, near Lake Windermere, Karagué (December). Bark a mouldy green. Leaves 
with a shining surface. Thorns an inch long, straight, opposite, pink-tipped; calyx pink-tipped ; corolla 
entirely red before the flower opens; on expansion it remains pink and the petals are white. The 
clusters of red unopened flowers were so brilliant as to conceal a scarlet-breasted bird which had perched in 
the tree. Flowers richly scented. —J. А. G.]

Hab. Madi, 3° М. lat., Dec. 1862, Col. Grant ! 
Not improbably a distinct species; but we have not the necessary material for description. Frutex 
depressus, ramulis ultimis glaberrimis ; foliis ovato-ellipticis v. -lanceolatis, glabris, nervo medio faciei 
superioris primum minutissime pilosulo. 
[A'dwarf shrub, growing low on the ground. "The peel of the thick roots, made into a flour, mixed with 
oil, and rubbed upon the body, is used by the natives to induce perspiration in fever cases. Тһе brother 
of the Sultan at Karagué thought himself a great doctor, and told me that this remedy seldom failed if 
the patient was careful to cover himself up on using it. Тһе root, when green, smells disagreeably, not 
unlike а mashed pea-pod. | — : 
The shrub has the appearance of an orange-tree; but the flowers are jasmine-scented, and the branches 
angular at the nodes. Leaves evergreen, with a glossy surface, of the same colour on both sides. Thorns 
double, straight, green, 2 inches long, black-tipped; the older ones thicken at their bases very much, 
and are forked to a pink point. Root fibrous, smells disagreeably : peeled and eaten, it is tasteless ;
