FLORA OF ADEN. 
165 
base ; petiole \ — J inch long ; leaflets usually linear-lanceolate, acuminate, 
J — 1J inches long, but varying to obovate mucronate and only inch 
long and J inch broad, all sessile or subsessile, strigose, the central one 
longer ; stipules minute, subulate. Racemes elongate, terminal, few- 
flowered, with internodes measuring |—1 inch ; bracteoles very minute ; 
pedicels capillary, -i inch long. Calyx inch long, externally clothed 
with appressed, short, pilose hairs ; segments narrow, acuminate, inch 
long, the upper one broader. Corolla yellow, long-exserted ; vexillum 
suborbicular, mucronate, inch long ; keel ciliate on the lower margin. 
Filaments alternately dilate above and united into a tube. Ovary stipi- 
tate; style incurved, J inch long ; stigma more or less distinctly bilobed, 
each lobe being flattened. 
Pod shortly stipitate, obliquely oblong, compressed, membranous, 
venulose, pubescent, not inflated. Seeds 18 (in Balfour’s specimens). 
Mowers and fruits : — March (Schweinf.). 
Locality : — Plain of Maala, together with other small herbs between 
shrubs of Acacia on rocky hills (Schweinf.) ; Koosaf Valley, ravine of the 
Jebel Ihsan on Little Aden (Defl.) ; without locality (Birdw.). 
Distribution : — Socotra, Somali-coast at Bulkar. 
Note : — ic This plant, which in its general habit and structure is 
thoroughly Crotalarioid, differs so decidedly from the type of the genus 
that it is with difficulty one can include it as a species. The fruit is not 
at all inflated or tumid, and the valves are quite thin and membranous 
with beautiful veining. In addition, there is a divergent character in the 
stigma, which [in the Socotran plant] is distinctly two-lobed, each lobe 
being flattened and pointed. But if we exclude the plant from this genus, 
1 can find no other in which to place it, and the characters are perhaps 
hardly sufficient to warrant at present the creation of a new genus ”

Description : — A low shrubby plant, 1| feet high or less, silky all 
over, much branching from the base ; branches erect, unarmed. Leaves 
few, sessile, exstipulate, digitately trifoliate ; leaflets small, 3 — 4 lines 
long, \ line broad, all of the same size, obovate-cuneate. 
Flowers sessile, solitary. Calyx canescent ; teeth linear-lanceolate, 
2 lines long, 3 — 4 times as long as the tube. Corolla white ; vexillum 
If lines long, undulate ; keel purpurascent at the apex ; rostrum falcate. 
Stamens diadelphous (!). Ovary 2 — 3-ovulate, glabrous ; style glabrous,
