costa converging forwards ; in the leaflets of the lowest pair the costa 

 is nearly median ; larger leaflets \ in. 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 J-l in. Sepals very acute, 4 lines 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.

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. Antheri- 

 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. 



A monotypic genus, based upon Mr. Mann's specimens. 



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 acumi- 

 nate, rounded at the base in the larger leaflets, entire (or with 2 or 3 

 obscure lateral teeth ?), glabrous, 1J-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, \ in. more or less. 

 Calyx-lobes J-| 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 dilated. Fruit roundish,
