Calyx as in Argyrolobium. Vexillum oblong, shorter than the obtuse 
carina. Stamens monadelphous. Ovary many-ovuled; stigma minute. 
me linear, compressed, sub-torulose. Endl. Gen. 6480. Benth. / in 
Hook. Lond. Journ. vol. 3.p. 353. Calycotome, E. Mey. Melinospermum, Walp. 
A few S. African suffrutices, having the habit of some Lebeckie, and the calyx, but 
not the corolla of Argyrolobuim, constitute this genus. The name is compounded of 
bis, twice, and xe:Aos, a lip ; alluding to the two-lipped calyx. _

1. D. strictus (E. Mey.! Comm. p. 36); erect, virgate, all the leaves 
alternate; leaflets linear-oblong ; racemules 2-3 flowered, terminating 
short ramuli, sub-paniculate ; calyx scarcely cleft to the middle, half as 
long as the ale, the teeth short, ovate. Benth.! l. c. p. 353- 
Has. On the Witbergen, Drege / (Herb. Bth., D.) 
A slender, fruticose, many-stemmed plant ; stems 12-15 inches high, simple, ramu- 
lose toward the top, appressedly pubescent. Leaflets minutely and appressedly 
puberulent, 4-5 lines long, 1-2 lines wide, sub-acute, tapering at base. Stipules 
none. Racemules on sub-uncial ramuli, crowded round the ends of the branches. 
Flowers yellow. Carina prominent and very blunt. 
2. D. lebeckioides (DC. Leg. Mem. p. 202. t. 3 5) ; erect, virgate, all 
the leaves alternate; leaflets linear-oblong or linear ; racemules 2-3 
flowered, teminating short ramuli, sub-paniculate ; calyx cleft beyond the 
middle, not much shorter than the ale, the teeth lanceolate, acuminate. DU.

Only to be known from D. by its deeply parted calyx, with longer and 
more acuminate lobes. It is questionable whether this character be constant. 
8. D. gracilis (E. & Z.! 1300); slender, diffuse,or procumbent, branches 
spreading ; floral leaves mostly opposite ; leaflets obovate ; peduncles 
short, filiform, 1-2 flowered, terminal or spuriously lateral; calyx deeply 
bilabiate, the teeth lanceolate, acuminate. Benth. ! 1. c. p. 354. D.patens,

Stems 1-2 feet long, ascending, diffusely branched. Leaves sub-distant, spreading ; 
leaflets 2~3 lines long, 1-2 lines wide, palish green, appressedly and minutely pubes- 
cent. Peduncles very slender, jointed ‘and bracteolate above the middle, i 
between a pair of leaves, or in the forkings of the branches. Flowers pale yellow, 
nodding. Our var. f., retained as a species by Bentham, appears to me to be a 
very trifling variety.
