than the leaves, £ to lin. long whilst in flower. Calyx 4 line, campanulate, 
argenteous ; teeth deltoid, cuspidate, as long as tube. Corolla 2 lines long, 
reddish-yellow, externally canescent. Pod about £in. long, 2 lines broad, at first 
argenteous, finally giabrescent, distinctly torulose. 
The variety ccerulea, with leaves 2 to 3in. long, leaflets 7 to 9, less silvery than the type, with 
more elongated racemes, 1 to 2in. long (the I. tinctoria var. brachycarpa, DC. Prod. ii. 224), has 
been met with as a naturalised plant by Mr. J. Keys at Bundaberg. 
11. * 1 . tinctoria (from furnishing a dye), Linn.; DC. Prod. ii. 224 ; J. G. 
Baker in Hook. Brit. Ind. FI. ii. 99. Indigo plant. A shrub 4 to 6ft. high, with 
twiggy woody thinly silvery branches. Leaves 1 to 2in. long ; leaflets opposite ; 
membranous, turning blackish when dried ; petiole i to lin. long. Racemes 
lax, nearly sessile, 2 to 4in. long. Calyx ^ line long, silvery ; teeth as long as 
the tube. Corolla about 2i lines, reddish-yellow. Pod 4 to 12 lines long, about 
1 line thick, giabrescent, scarcely at all recurved. 
I. Anil, Linn. DC. Prod. ii. 225, also commonly cultivated, a native of America, differs by its 
short congested racemes and pod turned back like a sickle. I.fiaccida, var. comtricta, Thwaites 
Enum. 411, from Ceylon, is probably a distinct species, but the flowers are unknown. It has the 
habit and leaves of I. tinctoria, with a slender tetraquetrous subtorulose 4 to 6-seeded pod. — Baker. 
Mr. Baker’s description and remarks are reproduced in full to assist persons to identify the 
plants, all being now and again met with as strays from cultivation, the kinds having been 
introduced by the late Colonial Botanist (Mr. Walter Hill), and the seed distributed by him to 
cultivators. 
12. I. pratensis (meadow), F. v. M. Rep. Burdek. Exped. 10 ; Benth. FI. 
Austr. ii. 198. A diffuse perennial, pale or hoary with the ordinary pubescence 
of the genus, the branches angular, ascending to 1 or 2ft. Leaflets about 13 to 
21, from broadly oval-oblong to narrow-oblong, obtuse with a fine straight point, 
^ to lin. long, the pinnate veins usually conspicuous underneath. Stipules 
setaceous, often 8 to 4 lines long, and small setaceous stipellae usually present. 
Flowers rather large, in pedunculate racemes longer than the leaves, the pedicels 
2 to 3 lines long. Calyx above 1 line long, the teeth shorter than the tube as in 
the shrubby species. Standard nearly 6 lines long ; keel almost acuminate. Pod 
cylindrical, straight, rather thick, 1 to Hin. long. 
Hab.: Bay of Inlets, Banks and Solander ; Broadsound and Keppel Bay, R. Brown; along 
various points of the E. coast and adjoining islands, A. Cunningham, M‘Gillivray, Henne, and 
others; in the interior, Mitchell ; on the Burdekin, F. v. Mueller ; Brisbane River, Fraser, F. v. 
Mueller, &c.; Mackenzie Hill, Leichhardt. 
13. I. saxicola (on rocks), F. v. M. Herb.; Benth. LI. Austr. ii. 199. A 
shrub of 3 or 4ft., with spreading branches, slightly hoary with a minute pubes- 
cence. Leaflets 5 or rarely 7, obovate or orbicular and very obtuse, mostly about 
lin. long, on petiolules of 1 to 2 lines, the pinnate veins scarcely prominent. 
Racemes pedunculate, rather slender, longer than the leaves. Calyx-teeth shorter 
than the tube, the upper ones broad and distant. Standard sessile, 3 lines long 
or rather more ; keel acute. Pod terete, spreading, ^ to fin. long, straight. 
Hab.: Gulf country. 
14. I, Baileyi (after F. M. Bailey), F. v. M. Fragm. ix. 43. A small under- 
shrub with shortly running roots from which slender stems arise to sometimes 
lft., but usually only a few inches; the branches angular, sparsely strigulose. 
Leaflets 5 to 9, rarely only 3, obovate, often thin, 2 to 6 lines long, very shortly 
petiolulate, glabrous above, glaucous and sparsely strigulose beneath. Stipules 
semi-lanceolate, about 1 line long. Stipellfe very short, subulate. Bracts 
fugaceous, minute, acute. Calyx conspicuously strigulose, scarcely 1 line long. 
The upper petals rosy towards the margin, the lowest very pale green, 2 lines 
long. Anthers very minute, cuspidate. Style glabrous. Pod deflexed, about 
lin. long and 1 line broad. Seeds hoary-brown, almost cubical. 
Hab.: Common on the Ironbark ridges about Brisbane.
