Forest Flora of Portuguese East Africa. 
FAMILY XXVII. — CONNARIACEzE. 
Flowers hermaphrodite, regular. Calyx 5-partite ; petals 5 ; stamens 5 or io, perigynous ; carpels free, 3 5, 1 -celled; ovules 2, collateral, ascending from the base of the 
inner angle of the cell, orthotropus. Capsule usually solitary, follicular, 1 -seeded ; seed arillale, exalbuminous. Trees or shrubs, leaves alternate, exstipulate, 3-foliate or pinnate 
(in our species) ; leaflets entire ; flowers small, in cymes or panicles. 
88. BRYSOCARPUS. Shrubs with pinnate leaves, cymose inflorescence ; stamens 10, sub-equal, or 5 longer and 5 shorter ; carpels 5 ; capsule dehiscing by a dorsal suture ; 
seeds red, fleshy and arilliform below the middle. 
B. orientalis, Baker. A small tree from the northern districts with pinnate leaves 15*24 c.m. long, and 21-25 leaflets in nearly opposite pairs, each 2-3 c.m. long, 1-1*5 
c.m. wide, elliptical, rounded at both ends and glabrous. Pod 1-2 c.m. long, slightly curved. 
B. ovatifolius, Baker. Leaves pinnate, 6-8 c.m. long, with 7-9 ovate acute leaflets 2 c.m. long, glabrous and shortly petiolate. Pod oblong-cylindrical, sessile, glabrous, 
1*5 c.m. long, 7 m.m. diameter. Nyasaland. 
B. maximus, Baker. A small tree with pinnate leaves 10-12 c.m. long, and 7-9 obovate acute glabrous leaflets 3-4 c.m. long, 2-2*5 c - m - wide. Pod oblong-cylindrical, 
sessile, 2 c.m. long, 7 m.m. diameter, curved. Rovuma. 
89. AGELjEA. Leaves petiolate, 3-foliate. Stamens 5 (in our species), free, included ; carpels 3-5, hairy ; capsules 1-2, velvety; seed erect, fleshy and arilliform from the 
base above the middle. 
A. Lamarkii, Planch. A climbing shrub. Leaves 3-foliate, the terminal one obovate, 7-10 c.m. long, 5-7 c.m. wide on a 3 c.m. petiole, the lateral ones sessile, unequal 
sided, all glabrous above and nearly glabrous below. Flowers small, in profuse panicles. Pod oblong, velvety. Zambesia. 
FAMILY XXVIII. — LEGU MI NOSiC. 
Flowers regular or irregular, often papilionaceous, hermaphrodite or polygamous. Calyx lobes 5, or 4 if 2 connate. Petals usually 5, sometimes fewer or absent. 
Stamens usually 10, sometimes fewer or many, hypogynous or perigynous, free or variously connate. Pistil superior, consisting of one i-celled carpel, usually flattened, with 1 or 
more axile ovules attached to its ventral suture. Style terminal. Frinjj usually a legume, 1 or several-seeded ; seeds exalbuminous. Leaves usually pinnate or 1-3 foliate, usually 
alternate, and stipulate. A vast l'amily and including trees, shrubs and herbs, and represented almost everywhere, usually taking a high place with regard to the number of 
species in any flora. I he trees are mostly tropical or sub-tropical, and the tree-flora of this Province may be described as a Leguminous one, these trees taking a prominent place 
everywhere, and forming in places large almost pure forests of Acacias in the south, of Brachystegia in the M’Chopes, and of Pterocarpus in the north. Of its 400 genera 83 are 
South African and 141 1 ropical African, 48 of these being common to both, only a few of these, however, being arborescent. The Family includes such a variety of useful plants 
that only the more important can be enumerated here. Among food materials for man or stock are Peas, Beans, Lentils, Carobs, Tamarinds, Clover, Lucerne, Tares, &c. Senna 
and others are medicinal ; the bark of many species of Acacia is used in tanning ; gums are yielded by Acacia and several other genera ; Indigo, Camwood and Logwood are 
important dyes, and the number of active poisons is very considerable. Valuable timbers, usually with black or dark heartwood, occur in most warm countries, and this Province 
is well provided with such. 
The Family divides more or less naturally into 3 Sub-Families, viz. : — 
1. Papilionaceae. Stamens 10 (many in Swartzia and Cordyla). Corolla irregular, papilionaceous; petals imbricate, the upper exterior. 
2. Caesalpinia. Stamens 10 or fewer. Corolla sub-regular, imbricate, not papilionaceous, the upper petal within the others. 
3. Mimosete. I' lowers minute in dense heads or spikes. Corolla regular, valvate in aestivation. Stamens 10 or many. Leaves 2-pinnate. 
SUB-FAMILY I— PAPILIONACE./E. 
Stamens 10 (many in Swartzia and Cordyla), free or variously connate. Corolla irregular, usually papilionaceous ; 
tube, usually arranged as 1 standard, outside in bud, 2 wing-petals , and 2 lower petals, frequently coherent by their lower edg 
or imparipinnate (in our trees). 
petals 5, free or somewhat adnate to the staminal 
es and forming the keel. Leaves simple, 3-foliate
