282 - XLVII. § CESALPINIEEH (OLIVER). | Cassia. 
costa converging forwards; in the leaflets of the lowest pair the costa 
is nearly median; larger leaflets fin. long. Common petiole appa- 
rently sometimes marked with sessile glands. Stipules rigid persistent, 
obliquely ovate-lanceolate, acuminate, falcate, very strongly longitudi- 
nally nerved, 4 lines long. Flowers solitary or in pairs, axillary, on 
pedicels of 4-lin. Sepals very acute, 4lines long. Stamens 10, un- 
equal, all perfect, anthers linear, dehiscing at or near the apex. Legumes 
immature in our specimen, pilose, similar to those of C. mimosoides.

11. DISTEMONANTHUS, Benth. et Hook. f. Gen. Plant. i. 578. 
Calyx-tube very short, turbinate; segments 5, linear acute, 3 outside 
in bud with 2 edges valvate (2 inside), slightly thickened at the margins. 
Petals 3, posterior oval or lanceolate, 2 lateral linear-oval. Anther- 
ferous stamens 2 between the posterior and lateral petals; filaments 
rather thick compressed, anthers linear or slightly tapering above, 
basifixed, dehiscing by an oblique terminal pore; staminodia 3, pos- 
terior very short lanceolate, lateral elongate-linear opposite to the 
lateral petals. Ovary with a short thick stipes, 4—5-ovulate ; style 
rather thick, as long as the ovary; stigma oblique terminal. Fruit not 
seen.—Tree. Leaves unfolding with the flowers, unequally pinnate ; 
leaflets alternate. Flowers in axillary few-flowered cymes. Bracts 
small, narrow, very early caducous.

1. D. laxus, Oliv. A tree attaining 60 ft. Extremities at first 
thinly rusty-pubescent, at length glabrous, marked in our specimens 
with numerous lenticels. Leaves 4—8 in. usually 5—7-foliolate ; leaflets 
membranous, elliptical or ovate- or oblong-elliptical acute or acuml- 
nate, rounded at the base in the larger leaflets, entire (or with 2 or 3 
obscure lateral teeth ?), glabrous, 14-3 in. long, 10 lines—1} in. broad ; 
petiolules 1-2 lines. Flowers in axillary shortly pedunculate few- 
flowered cymes, sometimes confluent at the extremities forming a lax 
more or less leafy panicle. Pedicels puberulous, 4 in. more or less. 
Calyx-lobes }—} in. long, at length reflexed. Ovary hirsute.

12. DIALIUM, Linn.; Benth. et Hook. f. Gen. Plant. i. 574. 
Calyx-tube very short, dilated or turbinate, segments 5 equal or 
nearly so, much imbricate, deciduous. Petals not exceeding the calyx- 
lobes, 1 or 2 or 0, lanceolate or oblong entire. Stamens 2; filaments 
short, anthers elliptical or oblong, dehiscing longitudinally. Ovary (in 
African species) very shortly and obliquely stipitate, the stipes being 
laterally adnate to the disk; ovules 2 or exceptionally 3; style subu- 
late; stigma terminal minute or scarcely dated, Fruit roundish,
