(After Professor Dunbar.) 
Calyx-lobes acuminate, the 2 upper ones united into 1 entire or slightly toothed 
one. Standard obovate or orbicular, erect or reflexed, with inflexed auricles at 
the base and 2 callosities inside ; keel incurved, obtuse. Upper stamen free, the 
others united ; anthers uniform. Ovary sessile, with several ovules ; style filifonn, 
incurved and rather thickened about the middle ; stigma terminal, small. Pod 
linear, flat, often falcate, acuminate ; valves rather thin, not indented between 
the seeds. Seeds nearly orbicular, with a short or oblong hilum and a thin or 
small strophiole, scarcely fleshy. — Trailing or twining herbs, usually tomentose, 
often viscid. Leaves pinnately trifoliolate without stipellae, leaflets usually 
sprinkled with resinous dots underneath. Stipules striate or small or none. 
Flowers usually yellow, in axillary racemes, singly scattered along the rhachis or 
rarely solitary in the axils. Bracts usually broad and membranous, but very 
deciduous. Bracteoles none. 
The genus extends, like Atylosia, over E. India and the Archipelago, the Australian species 
being one of the most widely dispersed. Nearly allied to Atylosia, it has the pod almost of a 
Dolichos, differing from Rhynchosia only in the more numerous ovules. — Benth. 
1. Do COnspersa (sprinkled with resinous dots), Benth. in PI. Jungh. i. 241, 
and FI. Austr. ii. 262. A slender twiner, hoary all over with a minute tomentum, 
scarcely becoming glabrous when old, and more or less sprinkled with r-esinous dots. 
Leaflets broadly rhomboidal, rarely lin. long, entire or the terminal one broadly 
sinuate 3-lobed. Flowers rather small, yellow, 2 together or rarely solitary in the 
axils of the leaves, on short pedicels. Calyx-lobes lanceolate-falcate, the upper 
and lower ones longer than the tube. Pod nearly straight or falcate, obliquely 
acuminate, 1 to l£in. long, glabrous or slightly tomentose. Seeds 6 to 8, with an 
oblong hilum and a rather thicker strophiole than in most species. — Dolichos (? ) 
rhynchosioides, Miq. FI. Ind. Bat. i. part 1, 185. 
Hab : Dunk Island, M‘Gillivray. 
The species ranges over the eastern provinces of India and the Archipelago up to S. China. 
It has very much the aspect of some of the common trailing Rhynchosias, but the pod is quite 
different. — Benth. 
64. ATYLOSIA, W. and Arn. 
(A and tulos ; no protuberance.) 
(Cantharospermum, W. and Arn .) 
Calyx-lobes acuminate, the 2 upper ones united into 1 entire or slightly toothed 
one. Standard orbicular, reflexed, with 2 inflexed auricles at the base and often 
with 2 slight callosities inside ; keel incurved, obtuse. Upper stamen free, the 
others united; anthers uniform. Ovary sessile, with several ovules ; style filiform, 
incurved and rather thickened above the middle ; stigma terminal, small. Pod 
oblong or broadly linear, straight, scarcely acuminate, 2-valved, with partitions 
between the seeds, the valves coriaceous or rarely thin, transversely indented 
between the seeds. Seeds ovate or orbicular, with an oblong hilum and a thick 
fleshy strophiole. — Trailing or twining herbs or erect shrubs, usually tomentose 
or softly villous. Leaves pinnately trifoliolate, without stipeline ; leaflets usually 
glandular-dotted underneath. Stipules small or none. Flowers yellow, solitary 
or clustered in the axils or at the end of axillary peduncles. Bracts usually broad 
and membranous, but so deciduous as to be rarely seen. Bracteoles none. 
The genus extends over E. India and the Archipelago and westward to the Mauritius. Of the 
Australian species, one is common over the whole range of the genus, the others are endemic. 
F. v. Mueller proposes to reunite it with Cajanus, to which it is closely allied, but the pod is 
differently shaped, and the strophiole appears to be constant. It only differs from some sections 
of Rhynchosia in the ovules always more than 2. — Benth.
