FLORA OF ADEN . 
99 
places (Schweinf.) ; plain of Maala, ravine near Steamer Point (Defl.) ; 
on the slope of the Shum Shum Range (Ellenbeck) ; without locality 
(Hook., Anders.., Thomson, Birdw., Perry, Marchesetti, Hildebrandt, 
Lunt) ; very common (Krause) ; copiosissime at Aden (Perrotet, Eemy, 
Courbon) . 
This plant is^endemic in Aden. 
Note — Cleome pruinosa approaches very nearly Cleome droserifolia 
Del., but it is more glaucous and often less glandular, or even glabrescent ; 
I the shape of the leaves is slightly different ; instead of being rounded like 
those of C. droserifolia , they are prolonged into a very short point. In 
the form reported by Courbon the leaves are almost glabrous and nearly 
distinctly cordate. 
C. Cleome brachystyla Defl. Bull. Soc. Bot. TV. XXXIV, 65 ; 
Morot, Journ. de Bot. I, 39. 
Cleome hispida Ehrbg. Herb. arab. ined., ex schedula herb. 
Parisiensis. 
Description : — An undershrub, 1^ — 2 feet high, densely and softly 
villose with glandular pilose hairs ; stem erect, ramose, multi-costate. 
Leaves 10-11 lines long, 8-10 lines broad, long-pet iolate, broadly ovate, 
sub-cordate, 3-5-nerved. 
Flowers in terminal, elongate, leafy racemes. Bracts small, sessile. 
Pedicels half as long as the bracts. Sepals linear-acute. Petals 
lanceolate, pale yellowish, by one half longer than the calyx. Stamens 
4, exserted. Style £ — f lines long, straight, shortly thickened ; stigma 
rotund ate, oblique, purpurascent. 
Siliqua 4 — 5-times as long as the pedicel (12 — 15 lines), non stipitate, 
ovate-cvlindric, sparingly hairy with small erect glandular aculei ; style 
persistent, shortly apiculate. Seeds small, smooth, yellow. 
Flowers and fruits from November to March (Schweinf.). 
Locality : — Above the coal depot of the Messag. Marit., Goldmore 
Valley, on rocks (Schweinf.) ; Koosaf Valley, Goldmore- Valley (Defl.) ; 
without locality (Birdw., Courbon, Balansa). 
Distribution .-—Island of Ketumbal (17° N.L.), Shugra, Somaliland. 
Note: — “ The specific name given by Ehrenberg is older than the 
one given by Defiers. But in addition to the fact that Ehrenberg did 
not furnish us with any description of the plant, it seems that several 
species have been distributed by the Berlin Museum under the name of 
C. hispida. The specimen received by the Paris Museum under that 
name is certainly C. brachystyla Defi. }> (Franchet.)
