XLIII. LEGUMINOSflE. 
[Indigo f era. 
3. I. glandulosa (glandulous), Willd.; DC. Prod. ii. 223 ; Bentli. FI. Austr. 
ii. 196. An annual or perennial with the habit nearly of I. trifoliata, but usually 
rather stouter and taller, more pubescent, and conspicuously marked with 
glandular dots, especially on the under side of the leaflets. Leaflets 3, from 
obovate to narrow-oblong, obtuse, f to lin. long, more hoary than in I. trifoliata. 
Flowers very small, in sessile racemes very short at first, but lengthening out to 
nearly ^in. Calyx glandular and hirsute, about 1 line long, the lobes subulate, 
much longer than the tube. Standard about 2 lines long, narrowed at the base, 
pubescent and glandular outside. Ovules 2. Pod reflexed, ovoid-oblong, almost 
4-angled, about 2 lines long, glandular and pubescent. — W. and Arn. Prod. 199 ; 
Wight, Ic. t. 330; Psoraiea Leichhardtii, F. v. M. Fragm. iv. 22. 
Hab.: Comet River, Leichhardt. 
The species is widely spread over E. India. It has the habit and foliage of I. trifoliata, with 
the pod of I. enneuphylla. — Bentli. 
4. I. haplophylla (single leaflet), F. v. M. Fragm. iii. 102 ; Bentli. 
FI. Austr. ii. 196. An erect or rarely diffuse branching herb of 1ft. or rather 
more, pale or hoary with a slight pubescence. Leaves simple, almost sessile, 
linear or very narrow-oblong, mostly 1 to 2in. long. Racemes slender, pedun- 
culate, scarcely exceeding the leaves. Calyx-lobes much longer than the tube, 
but much shorter than the petals. Standard narrowed at the base, but not 
clawed ; keel obtuse. Pod straight, rather slender, cylindrical, spreading, often 
lin. long or rather more. 
Hab.: Islands of the Gulf of Carpentaria, R. Brown. 
5. I. trifoliata (three-foliolate), Linn.; DC. Prod. ii. 223 ; Bentli. FI. Austr. 
ii. 197. Stock perennial, with several ascending or erect rather slender stems of 
1 to 1 or 1-J-ft., the pubescence very short and scarcely hoary. Leaflets 3, on a 
slender petiole, obovate-oblong, cuneate or narrow-oblong, mostly \ to lin. long, 
green or slightly hoary underneath. Racemes sessile, exceedingly short. Flowers 
very small. Calyx-teeth much longer than the tube, but scarcely so long as the 
claws of the lower petals. Standard about 2 lines long, narrowed into a short 
broad claw ; keel obtuse, pubescent and glandular as well as the standard. Pod 
slender, reflexed, about |in. long, with 4 prominent angles or narrow longitudinal 
wings, many-seeded. — W. and Arn. Prod. 201 ; Wight, Ic. t. 314 ; F. v. M. 
Fragm. iii. 104. 
Hab.: Bustard Bay, Banks and Solander ; Northumberland Island, R. Brown; Glasshouse 
Mountains, F. v. Mueller ; along the coast and adjoining islands, A. Cunningham, M'Gillivray, 
Henne, Dallacliy, also in Leichhardt's collection ; and many other localities. 
The species is widely spread over E. India and the Archipelago. It is always much more 
slender than I. trita, with more closely sessile short spikes or clusters of much smaller flowers. 
— Benth. 
6. I. trita (worn), Linn. DC. Prod. ii. 232 ; Benth. FI. Austr. ii. 197. A 
decumbent or suberect perennial of ^ to IJft., pale or hoary with a minute 
pubescence. Leaflets 3, or very rarely 5, on a rather rigid petiole, from broadly 
obovate and 3 or 4 lines long to elliptical-oblong and above lin. long. Flowers 
small, very nearly sessile ; the racemes sometimes short, dense, and nearly sessile, 
sometimes pedunculate, interrupted, and attaining several inches. Calyx-teeth 
much longer than the tube, but not exceeding the claws of the lower petals. 
Standard nearly 3 lines long, narrowed at the base but scarcely clawed ; keel 
almost acuminate. Pod rather rigid, usually incurved, obscurely quadrangular, 
with thickened sutures, 1 to l£in. long or even more. — Hook. Comp. Bot. Mag. i. 
t. 16 ; W. and Arn. Prod. 203 ; Wight, Ic. t. 315, 386 ; F. v. M. Fragm. iii. 103.
