2. E. Burkei (Benth.!); leaflets broadly linear or linear-oblong, not 
very oblique, obtuse ; racemes lax, the pedicels as long as the calyx ; 
legume evidently netted with veins. Zey./ 560.

Similar in habit to the preceding, but with longer, broader, blunter, and paler leaf- 
lets, and fewer flowers in the raceme. Leaflets 6—7 lines long, 2-24 wide, round-topped.

Flowers of two kinds in the spike; the uppermost flowers herma- 
phrodite and sessile, as in Hntada ; the lower neuter, with calyx and 
corolla as in the perfect, to long, slender filaments without anthers, and 
a rudiment of ovary. Legume linear, twisted, compressed, membranaceo- 
coriaceous or subcarnose, one-celled, without pulp, indehiscent, or the 
valves irregularly breaking from the sutures, Benth. in Hook Journ. 
Vl. 4, De 353. 
African and Asiatic shrubs. The twigs occasionally abortive and converted into 
spines. Flowering branchlets in the axils very short, fasciculately leafy, covered

two colours, and oraxus, a spike. 
1. D. nutans (Benth. ! 1. c.); twigs, petioles, and peduncles downy or 
glabrate; pinnze subdistant, 8-12-jugate; leaflets 20—30-jugate, ciliate 
or glabrous; glands between the pinnz stipitate; spikes shorter or 
scarcely longer than the leaves, Caillea dichrostachys, Guill. & Perr. Fl.

or multi-jugate, mostly pubescent. Leaflets 3~4 lines long, t line wide. Spikes 14 
inch long, on peduncles of variable length. Legumes 2~5 inches long, 3 lines wide 
2. D. Forbesii (Benth. 1. ¢.) ; “nearly glabrous; pinns 3—-4-jugate ; 
leaflets 10-15-jugate ; glands between the leaflets stipitate ; spikes 
slender, scarcely longer than the leaf. Benth. /

More glabrous than D. nutans, with fewer pinne and leaflets.

Stamens 10 ; filaments free, the 5, alternate shorter ; anthers with a very 
minute, sessile gland. Legume sessile, semiorbicular, plano-compressed,
