4. C. juncea (rash-like), Linn.; DC. Prod. ii. 125 ; Benth. FI. Austr. ii. 179. 
An erect annual, attaining many feet, with few, erect, sulcate-striate, silky- 
pubescent branches. Leaves simple, nearly sessile, oblong or linear, obtuse, 1 to 
3in., or when narrow, 4in. long or more, glabrous above or nearly so, pubescent 
underneath. Flowers rather large, yellow, not numerous, in a long terminal 
raceme. Calyx tomentose, 4 to 6 or even 7 lines long, deeply divided into narrow- 
lanceolate nearly equal lobes, the 2 upper ones truncate or booked at the top. 
Petals slightly exceeding the calyx, the standard usually pubescent, and some- 
times purpurascent (F. v. M. Fragm. ix. 156). Ovary sessile, villous, with about 
20 ovules. Pod above lin. long, densely clothed with a rusty tomentum. — Andr.

The species is common in East India, where it is much cultivated for the fibrous bark, used 
as a substitute for hemp under the name of Sunn.- -Benth. 
5. C. linifolia (flax-leaved), Linn, f.; DC. Prod. ii. 128; Benth. FI. Austr. 
ii. 180. A perennial with a thick rhizome, or sometimes annual, exceedingly 
variable in aspect, usually silky pubescent or villous, sometimes clothed with long 
spreading hairs or with a close or woolly white tomentum, often drying black. 
Stems erect or ascending, from a few inches to 1-J-ft. high. Leaves simple, the 
lower ones, or nearly all in the smaller forms, obovate or oblong, obtuse and 
mostly under |in. long, the upper ones, or nearly all in the elongated varieties, 
narrow-oblong or linear, 1 to 2in. long, obtuse or almost acute. Flowers small, 
yellow, in loose terminal racemes. Calyx 3 to 4 lines long, divided nearly to the 
base into 2 lips, the upper one 2- toothed, the lower one 3-lobed to the middle. 
Petals not exceeding the calyx. Ovary sessile, glabrous, with 10 to 20 ovules. 
Pod ovoid-globular, scarcely exceeding the calyx. — W. and Arn. Prod. FI. Ind.

and others. A very common plant in Queensland. 
R. Brown’s herbarium comprises a particularly instructive series of specimens connecting the 
different forms, which have at first sight the appearance of distinct species. Amidst all these 
varieties the species is easily recognised by the calyx and pod. —Benth. 
6. C. humifusa (low-spreading habit), Grah.; J. G. Baker in Hook. FI. Brit. 
Ind. ii. 67. Stems slender, flexuose, much branched, densely clothed with short 
spreading, yellow-brown silky hairs. Leaves nearly sessile, very obtuse, mem- 
branous, pale, glaucous on the under side, equal at the base, \ to lin. long. 
Peduncles curved, densely silky, usually two or three times as long as the leaves, 
sometimes leafy below. Pedicels cernuous, lower as long as the calyx. Calyx 
about 1|- line long, densely silky ; teeth linear, very long. Corolla yellowish, not 
exserted. Pod long stalked, 3 lines long. Seeds 6 to 8. 
Hab.: Here and there from Brisbane River to Rockingham Bay. 
7. C. calycina (calyx large), Scliranck , PI. Rar. Hort. Monac. t. 12 ; Bmth. 
FI. Austr. ii. 180. A decumbent or nearly erect annual, 1 to l^ft. high, not 
much branched, villous with appressed or scarcely spreading hairs. Leaves 
simple, nearly sessile, from short and oblong to lanceolate or linear and 2 to 6in. 
long, glabrous or nearly so above, villous underneath. Flowers in terminal 
racemes, remarkable for their large pendulous calyx, often fully lin. or more long, 
thickly covered with long spreading rusty hairs, deeply divided into nearly equal
