17. C. laburnifolia (Laburnum-leaved), Linn.; DC. Prod. ii. 130; Benth. 
LI. Austr. ii. 184. An erect glabrous shrub of several feet, with rather slender 
terete branches. Leaflets 3, petiolulate, ovate, mostly acute, 1 to 2in. long, on a 
rather long common petiole. Flowers large, yellow, in loose terminal or leaf- 
opposed racemes. Calyx 5 to 6 lines long, the lobes acuminate, much longer than 
the broad tube. Standard broadly ovate, shortly acuminate, fully fin. long ; 
wings not half so long, broad, with the transverse folds particularly prominent ; 
keel with a long straight beak, as long as the standard. Ovary on a long stipes, 
glabrous, with 20 to 30 or more ovules. Pod ljin. long or more, on a stipes 
much longer than the calyx. — Rheede Hort. Mai. ix. 27 ; W. and Arn. Prod. 193; 
F. v. M. Fragm. iii. 53. 
Hab.: Rockingham Bay ; Cape Cleveland, A. Cunningham; Cape Upstart, ALGillivray ; sandy 
shores of the Burdekin, Dawson and Burnett Rivers, F. v. Mueller; Port Denison, Fitzalan ; 
Burdekin and Bowen Rivers, Bowman. 
The species is common on the sandy coasts of East India. — Benth. 
18. C. quinquefolia (five-foliolate), Linn.; DC. Prod. ii. 135 ; Benth. FI. 
Austr. ii. 184. An erect annual, attaining 3 or 4ft., with a hollow stem, glabrous 
or silky-pubescent. Leaflets from 3 to 7, usually 5, lanceolate or linear, obtuse, 
1^ to 3in. long or the central one longer, almost sessile on a rather long common 
petiole. Flowers large, yellow, in loose terminal or leaf-opposed racemes. Bracts 
lanceolate, acuminate, reflexed. Calyx 5 to 6 lines long, the lobes broad, acumi- 
nate, scarcely longer than the tube. Standard broad, very obtuse, about fin. 
diameter ; wings rather shorter ; keel with an acute curved beak. Pod glabrous, 
about 2in. long, on a stipes equal to or longer than the calyx. — W. and Arn. Prod. 
194 ; Rheede Hort. Mai. ix. t. 28. 
Hab.: On the lower Burdekin River, Bowman. 
The species is generally dispersed over E. India and the Archipelago. 
23. *LUPINUS, Linn. 
(Said to be derived from lupus, a wolf ; on account of the plant being supposed to 
destroy the fertility of the soil.) 
Calyx deeply 2-lipped, upper lip entire or emarginate, lower slightly 3-toothed. 
Standard ovate, wings large, oblong, including the small upcurved rostrate keel. 
Stamens united in a close tube. Ovary sessile, ovules many. Style slender, 
upcurved, glabrous. Stigma capitate, ciliate. Pod compressed, silky, septate 
between the seeds, 2-valved. 
A large genus almost entirely American. 
Now and again one or more species of this genus is met with as a stray from garden culture. 
24. TRIGONELLA, Linn. 
(Flowers triangular.) 
Calyx-teeth nearly equal. Petals free from the staminal tube ; standard 
obovate or oblong, narrowed at the base but scarcely clawed ; wings and keel 
shorter, obtuse. Upper stamen free or at first united with the others ; filaments 
not dilated ; anthers uniform. Ovary sessile or shortly stipitate, with several 
ovules ; style filiform. Pod either linear straight or curved, or in species not 
Australian flat and falcate, or short with a long beak, 2-valved or indehiscent. 
Seeds not strophiolate. — Herbs, often strong-scented. Leaves pinnately 3- 
foliolate, the leaflets usually denticulate. Stipules adnate to the petiole. Flowers 
yellow, white or blue, in axillary heads, umbels, or short racemes. 
The genus is rather numerous in species in the warmer extratropical regions of the northern 
hemisphere in the Old World, one of the common ones being also found in South Africa. The 
only Australian species is very nearly allied to an Egyptian one, although not quite identical 
with any form hitherto observed there. — Benth.
