318 XLVII. § CESALPINIEEH (OLIVER). [ Cynometra. 
3. GC. (Hymenostegia) floribunda, Benth. in Linn. Trans. xxv. 318. 
A tree of 30 ft. (Mann); extremities puberulous at first, early gla- 
brous. Leaves 2-3 in. long, leaflets sessile, in 4-6 pairs, obliquely 
trapezoidal, obtuse’ or very obliquely broadly pointed, coriaceous, gla- 
brous or thinly and very minutely pubescent beneath at first, }-1} in. 
long, the upper leaflets usually the longer. Flowers in simple racemes 
2-3 in. long from the upper axils, collectively forming ample leafy 
anon rachis of raceme pubescent. Pedicels about 4 in. long. 
racts caducous. Bracteoles petaloid, in pairs a little under the calyx- 
tube, broadly ovate, sessile, with a cordate base, }~4 in. long, persis- 
tent at least until expansion. Calyx glabrous or nearly so, tube turbi- 
nate, segments of limb 4. Posterior and 2 lateral petals ovate- or ob- 
ovate-oblong, 2 anterior minute. Stamens 10. Ovary hairy, the stipes 
partly adherent to the side of the calyx-tube; style glabrous. Ovules 
2. Fruit not sent home. 
Upper Guinea. Muni river, lat. 1° N., Mann! 
4. ©. (Hymenostegia) laxiflora, Benth. in Linn. Trans. xxv. 318. 
A glabrous tree of 25-40 ft. or more; extremities slender. Leaflets 
submembranous or at length coriaceous, 1—2-jugate, usually 1-jugate, 
when 2-jugate the upper pair much larger than the lower, ovate- 
lanceolate falcate acuminate, base very oblique, upper or only leaflets 
2-4 in. long; petiole 3—5 lines. Racemes terminal, simple, glabrous, 
few-flowered. Pedicels slender, 3-5 lines long. Bracteoles petaloid, 
similar to those of C. floribunda, 4-4 in. long, }—} in. below the calyx. 
The structure of the flower so far as I have ascertained is similar to 
that of the foregoing, the ovary, however, is glabrous. Ovules 2. 
Lower Guinea. Golungo Alto, Angola, Dr. Welwitsch! 
Dr. Welwitsch describes the flowers as whitish rose-coloured, the heart-wood as deep- 
rose or blood-colour, tough and durable. 
In the same province of Angola Dr. Welwitsch collected specimens of a nearly allied 
plant in fruit only, differing in the leaflets being rarely 1-jngate, shining, and more coria- 
ceous in texture. The legume is very oblique, about 3 in. long, 14 in. broad, the 
valves thinly but firmly coriaceous, each separating in two layers when dry. It may 
be distinguished as var. nitidula. Welw. 
5. ©. (Hymenostegia) Afzelii, Oliv. Very near to C. laxiflora. 
Extremities and inflorescence minutely puberulous. Leaflets rather 
coriaceous, 2-jugate, upper pair much larger, obliquely elliptical or 
ovate-elliptical, acuminate, usually obliquely cuneate at base, glabrous, 
without the minute subprominent reticulation of C. laxiflora ; petiole 
winged. Terminal racemes few- or several-flowered. Bracteoles as in 
the above, inserted at the base of the calyx-tube.

31. APHANOCALYX, Oliver in Hook. Ic. Plant. xi. 53. 
Flowers enclosed in bud between a pair of sepal-like valvate brac- 
teoles. Calyx obsolete or reduced to minute teeth. Petal 1, posterior,
