XLIII. LEGUMINOSiE. 
[Desmodium. 
the upper suture straight or slightly indented, and often more or less dilated, the 
lower more deeply indented ; articles 2 to 4, thin, flat, with very fine transverse 
reticulations, scarcely separating from each other and sometimes perhaps opening 
on the lower edge. 
Hab.: Moreton Bay to Rockingham Bay. 
The species is common in India, extending over the Archipelago and into S. China. This and 
D. Muelleri seem to connect the section Sagotia, founded on the common tropical D. trijlorum , 
DC., with D. trichostachyum and D. neurocarpum (N. Australia), which I have referred doubtfully 
to Heteroloma, although they have the solitary pedicels of Sagotia. They all come very near 
in habit to some of the looser-flowered species of the section Nicolsonia, but the pod is much less 
disposed to open on the lower edge. — Benth. 
45. PYCNOSPORA, R. Br. 
(Seeds dense.) 
Calyx, 2 upper lobes united into one. Standard nearly orbicular, narrowed at 
the base ; wings adhering to the keel ; keel obtuse, with small lateral appendages. 
Upper stamen free, or at first united with the others, anthers uniform. Ovary 
sessile, with several ovules. Style subulate, with a terminal stigma. Pod 
oblong, turgid, 2-valved, transversely veined. Seeds several, not strophiolate. — 
An undershrub, with the habit of Desmodium. Leaves pinnately 8-foliolate or 
1-foliolate, with stipellae. Flowers small, in terminal racemes or panicles. 
The genus consists of a single species, extending over the Indian Archipelago to S. China. It 
is very nearly allied to Desmodium, except in the pod (nearly that of Crotalaria), which would 
technically remove it from Hedysarece, but it has no immediate affinities in any other tribe. —

1 P. hedysaroides (Hedysarum-like), E. Br. in W. and Am. Prod. 197 ; 
Benth. FI. Austr. ii. 236. Stock perennial, with several decumbent or ascending 
branched stems, 1 to 2ft. long, pubescent or hairy. Leaves pinnately 
3-foliolate ; leaflets obovate or obovate-oblong, the terminal one in some 
specimens scarcely -gin., in others above lin. long, the lateral one usually 
smaller or sometimes wanting. Stipules striate, subulate-acuminate, frequently 
deciduous. Flowers about 2 lines long, purplish, in terminal slender racemes of 
2 to 3in., or occasionally longer and branching into panicles ; pedicels short 
in pairs. Bracts rather broad, acuminate, membranous, striate, falling off long 
before the flower expands. Pod 3 to 4 lines long, very turgid, slightly pubescent, 
the valves thin, with very fine transverse reticulations. Seeds 6 to 8 small, 
reniform, — P. nervosa, W. and Arn. Prod. 197. 
Hab.: Gulf of Carpentaria, B. Brown; Broadsound, R. Brown, Boivman ; Dunk Island, 
M'Gillivray ; Rockingham Bay, Rockhampton, Gin Gin, &c. 
46. URARIA, Desv. 
(Origin doubtful.) 
Calyx-lobes subulate-acuminate, spreading, the 2 upper ones (lowest by the 
resupination of the flower) shorter. Standard orbicular or obovate, narrowed into 
the claw ; wings adhering to the obtuse keel. Upper stamen free, the others 
united ; anthers uniform. Ovary sessile or nearly so, with 2 or more ovules ; 
style filiform with a capitate terminal stigma. Pod nearly sessile, contracted 
between the seeds ; articles ovate, folded back upon each other within the calyx. — 
Herbs or undershrubs. Leaves pinnate of 3, rarely 5 or 7 leaflets, or sometimes 
of a single terminal leaflet, usually prominently reticulate, with stipellae. Stipules 
free, acuminate, striate. Flowers purplish or yellowish, in terminal racemes 
either slender and elongated or dense and spike-like, the pedicels in pairs, 
indexed at the top so as to reverse the flowers. Bracts usually broad, acuminate ; 
bracteoles none.
