Forest Flora of Portuguese East Africa. 
S. suberosa, (New species.) 1 Ve. rn. name — xo, Morebo ; but several other trees have very similar names. A small tree having pubescent leaves ; on old wood cordate- 
ovate, abruptly pointed, 3-7 nerved, 5 c.m. long and wide ; on young wood ovate or ovate-lanceolate, from 3 c.m. long and 15 c.m. wide upward, on 1 c.m. petioles, 
and often bearing recurved spines 1*5-2 c.m. long in the axils. Flowers not seen. Fruit 6-8 c.m. diameter, yellow when mature. Bark corky, ridged, on the main 
stem 2-5 c.m. deep, and cork showing even on the twigs. This has the whole habit of S. spinosa but the bark is very different. Seen only in the forests of Magenja 
da Costa near Maquebella. Sim 6013.

190. NUXIA. Evergreen trees having simple opposite or whorled leaves, paniculate-cymose inflorescence, 4-merous flowers, and dry capsular fruits. Calyx 4-toothed, tubular ; 
corolla shortly tubular, limb 4-fid, the tube spilling off above the base after the flower opens; stamens 4, exserted ; ovary 2-celled ; ovules many; style simple; 
capsule 2-valved, many-seeded, septicidal. A small African genus. 
N. oppositifolia, Bth. Vern. name — 15, Simalashant. Often an upright shrub, occasionally a tree 10-20 metres high, 60 c.m. diameter of stem, and with useful close- 
grained timber. Twigs slender, leaves linear-lanceolate, 7-8 c.m. long, 5 m.m. to 1*5 c.m wide, often erosely toothed, puberulous and viscid when young, glabrous 
when old. Inflorescence terminal and in the upper axils, viscid, cymose-corymbose, dichotomous; flowers very small. Frequent in the Maputa Lebombos, below 
Estatuene. Occurs also in Natal.

FAMILY XLVIIL— BORAGINEAZ. 
A large Family of herbaceous plants, but including also a few trees and shrubs. Flowers hermaphrodite, regular or almost so. Calyx 5-lobed, short. Corolla cam- 
panulatc or rotate, 5-lobed ; stamens as many (sometimes 1 abortive), at the top of the corolla-tube, exserted. Ovary superior, in local trees entire with a terminal style and 
producing a fleshy 4-celled, 4-seeded drupe. Seeds erect. Stems terete, with alternate simple exstipulate leaves and paniculate or cymose inflorescence. The herbaceous genera 
vary from the above in having mostly 4-lobed ovary, with gynobasic style. 
1 9 1 • CORDIA. Calyx irregularly 3-5 lobed, campanulate ; corolla rotate, with a short tube and 5-6 parted limb ; stamens as many as the corolla-limb, but sometimes not all 
perfect. Ovary 4-celled with a twice 2-fid style. Fruit a globose drupe with 4 pyrenes ; stones hard, seeds exalbuminous, erect, oblique ; cotyledons plicate. A 
large and mostly tropical genus, having alternate or sub-opposite simple leaves, and flowers in terminal panicles or cymes. 
C. caffra, Bond. Vern. names— 4, Kokoshuan ; 6, Impsetu. A large or small tree with whitish bark, soft sapwood, and durable heartwood. Leaves 5-10 c.m. long, 
3-4 c.m. wide, on slender 5 c.m. petioles, exceedingly irregular as to shape and margin, but usually ovate-lanceolate, narrowed to both ends, deeply and irregularly 
toothed, and densely but minutely yellow-pubescent when young, afterwards nearly glabrous. Calyx 3-lobed in flower, but accrescent and 4-5 lobed in fruit ; corolla 
nearly regular, but 2 lobes somewhat connate; 4 stamens equal, the fifth reduced or absent ; ovary 4-celled, each cell x-uvuled. Fruit a yellow globose drupe, 1*5 
c.m. in diameter, with 4 hard pyrenes. Cymes terminal when in flower, but by the production of a branch directly under them becoming lateral aftenvards. 
frequent at Umbelusi and found occasionally north to Inhambane ; more common in Natal and eastern Cape Colony. For illustration see “Forest Flora of CaDe 
Colony,” 280, Plate CXVI. P 
192 EHRETIA. Calyx 5-parted ; corolla-tube very short, with 5 rather longer spreading lobes, imbricate in bud. Stamens 5, equal, placed near the top of the tube, exserted. 
Ovary entire, globose, with a terminal slender 2-fid style. Drupe globose, with 4 pyrenes. Seed erect; albumen scanty; cotyledons flat. A considerable genus 
of trees and shrubs, tropical and sub-tropical. 
E. hottentotica, Burch. Vern. names— 4, Jabekwa ; 13, Umhleli. A shrub or small tree 2-5 metres high, sometimes erect in habit, but more frequently with drooping 
whitish branches. Very variable in size of leaf and in pubescence or in the absence of it. Leaf 3-8 c.m. long, 2-4 c.m. wide, oval or obovate, entire, pubescent or 
glabrous, with scabrid margin and short petiole. Cyme corymbose, many-flowered, conspicuous ; corolla usually blue or lilac colour, lighter inside than outside,
