3. C.? mimosoides, Welw. A low shrub, with a stout decumbent 
root-stock, giving off erect or ascending leafy branches from a span to 
1 ft. in height ; branches minutely pubescent or glabrate, slender, rather 
rigid. Leaves 14-3} in. long, distichous; leaflets in 14-25 pairs at 
intervals of 1—2 lines, oblong or linear often slightly falcate obtuse or 
broadly obliquely pointed, rather coriaceous, nervose, glabrous or gla- 
brescent, sessile, } to over 3 in. in length; rachis puberulous or glabrous. 
Flowers (very sparingly produced, only seen in one specimen), 4 or 5 
together at the extremity of a leafy branch. Pedicels about 1 line. 
Involucral bracteoles thin, 2 lines long. Calyx-tube turbinate, glabrous, 
4 line long, with 3 or 4 minute teeth. Petal elliptical, concave, three 
times as long as the calyx. Perfect stamens 2, 1 with an apparently 
effete anther. Ovary compressed, glabrous except on the sutures, on a 
short pilose stipes; ovules 2. Legume... . 
Lower Guinea. Pungo Andongo, Angola, Dr. Welwitsch ! 
Specimens in leaf only, probably of a fourth species, allied to C. mimosoides, were 
gathered in Pungo Andongo by Dr. Welwitsch. In habit it is similar, but attaining 
20-30 in. Leaflets in 18-24 pairs, oblong lanceolate obtuse, with the midrib widely 
eccentric immediately within the upper margin, 4-14 in. in length. Stipules subulate 
or filiform, erect, }—1 in. long, caducous. 
20. BRACHYSTEGIA, Benth. ; Benth. et Hook. f. Gen. Plant. i. 582. 
Flowers enclosed in bud between a pair of sepal-like valvate brac- 
teoles. Perianth reduced to 2 or more (5—7) minute oblong linear or 
subulate scales, usually not exceeding 1—2 lines in length. Stamens 
10-13; filaments slender, more or less distinctly connate at base; an- 
thers ovate or elliptical, versatile, dehiscing longitudinally. Ovary 
-subsessile or stipitate, 5-8-ovulate; style elongate, slender; stigma 
terminal, obtuse. Legume oblong, usually at right angles to its short 
stipes, compressed, ventral suture often slightly dilated, 2-valved ; valves 
coriaceous or woody, at length smooth. Seeds ‘‘ few, transverse, com- 
pressed, exalbuminous ; cotyledons flat, with a short straight included 
radicle.’—Trees, unarmed. Leaves abruptly pinnate. Flowers rather 
small in terminal simple spicate dense racemes or axillary paniculate 
confluent glomerules. Bracts caducous ; bracteoles present at flower- 
ing, valvate over the bud. 
Confined to Tropical Africa. 
Leaflets usually in 3-6 pairs. 
Leaflets pointed or acuminate, glabrous. Pedicels 2-3 lines . 1. B. appendiculata.

1. B. appendiculata, Benth. in Linn. Trans. xxv. 313, t. 42. Tree 
of 20-40 ft., wholly glabrous, or the inflorescence often puberulous ; 
extremities slender, divaricately branched. Leaflets usually in 4 pairs, 
membranous or thinly coriaceous, shining and venose, varying from 
oval or lanceolate to oblong-elliptical, often gradually obtusely acumi- 
nate or broadly pointed obtuse or minutely emarginate, base unequal,
