ovali-oblongæ. Ovarium hirtum, 3-loculare, in stylum pilosulum angustatum ; ovula geminata; stigma 
capitatum. Capsula subglobosa v. cldvato-globosa, breviter tomentosa, stipitata, 3-valvis, valvis coriaceis, 
1 poll. diam., stipite 1—4 poll. Semina oblonga, aristata, arillo соссшео. 
Hab. Madi, flower in Jan. 1863, Col. Grant ! Widely spread in Tropical Africa. We 
have excellent specimens collected by Dr. Kirk in the Zambesi. 
The oil and tallow obtained from the seeds is used by the natives in cookery. A figure of it is given 
by Bertoloni in his “ Miscellanea Botanica, ix. tab. 2, under the name of Mafureira oleifera. Mafuta, 
Dr. Kirk says, is a name meaning fat, and is “ applied to many different oil-seeds.” 
[Tree 8 feet in circumference of trunk. Bark black, much ‘fissured into two-inch oblongs; bark of 
branches grey, but neither smooth nor rough, not gummy but watery. In flower and leaf end of J anuary 
at 3° to 5° N. lat.; seeds not then developed. Leaves 9-foliolate, drooping, have a soft taste, and downy 
beneath. Ribs very parallel and prominent behind. Calyx green; corolla nearly three times the length 
of the calyx, yellowish; the extremity of the petals is thickened, and they hang down, exposing the 
column of stamens. Pistil same length as stamina, and seemingly divided into three at its tip. Unknown 
to all our men except one, who used its bark in a case of syphilis. The natives obtain from this tree a 
liquid which they use as a sauce.—J. A. G.]

Hab. Madi, Feb. 1863, Col. Grant! Also in Senegambia, and the same, or a near ally, 
we have from Zambesi-land (Manganja hills). 
[Tree: trunk 10 feet in circumference; bark has grey scales, is thick and soft; no smell from an 
incision. Gum exudes from wounds; it sticks to the teeth, is tasteless, smelless, shiny, fractured, and 
. . the colour ofpale amber. In flower and fruit February at 4? N. lat. Fruit a hard thick capsule, the 
size of a small orange, separates into four regular segments, exposing numerous brown curved scales of 
seeds, which are packed on end, one on the top of the other. This tree differs from the following (Soy- 
mida? sp.) in its fruit, its leaves, and its gum.—J. А. G.] ; 
3. SoYMIDA P sp. Å single leaf only. 
Hab. Madi, Col. Grant ! 
Dr. Schweinfurth, in *Reliquiæ Kotschyane,’ 37, describes а. Soymida? roupalifolia, adding that 
Col. Grant’s plant, enumerated in the Appendix to Speke’s Journal, may perhaps be the same plant. 
This, however, cannot be, as the form of the leaflets сс. described by Schweinfurth does not accord with 
ours. The leaf has all the appearance of that of a Soymida; the leaflets are subopposite and broadly . 
elliptical. I omitted all reference to it in * Flora of Tropical Africa.” 
[Native name “ mbawa.” Huge tree. Bark grey, not scaling, not fissured. At 4 feet from the 
ground its circumference was 15 feet. It branched at 20 feet from the ground, but the trunk continued 
to taper upwards for 30 feet. Leaves 6 to 10-foliolate; leaflets 52 by 3 inches, ovate. In fruit at 4° N. 
lat. in December. Each fruit is of the size and has the look of a large pomegranate, only that the five 
divisions of the fruit are apparent on its surface. Its stalk shows no part of the calyx. The five cells 
contain many flat winged seeds, which are white and packed together like cards; size 1} x 1 inch, in- 
cluding the wing. Gum accumulates, precisely like the runnings from a tallow candle, upon the trunk. 
It shines, is transparent, of a wax colour, smells disagreeably (as also does the inside of the seed-vessel), 
seems insoluble in the mouth, and burns like а bit of wood. The natives tell me that immense canobs 
are made from the trunk of this tree at Lake Nyassa, in 13? S. lat.—J. А. G.]
