1. C. nitrariaceum (in allusion to its salty nature), F. v. M. ; Bentli. FI. 
Austr. v. 158. A rigid divaricately branched or prostrate shrub or undershrub, 
hoary or mealy-white all over with a minute tomentum, the smaller branchlets 
often spinescent but not nearly so slender as in Rhagodia spinescens. Leaves 
alternate, sometimes clustered at the base of the flowering branchlets, linear 
oblong, or linear-spathulate, very obtuse, entire, contracted into a short petiole, 
from under Mn. to nearly lin. long. Flowers sessile, usually clustered in 
interrupted or dense spikes, either simple and terminal or forming short 
divaricate branches to a terminal panicle, mostly hermaphrodite with a few 
males intermixed. Perianth-segments broad, thick, concave, slightly imbricate 
in the bud. Stamens 5, shortly exserted, the filaments flat and glabrous. 
Ovary ovoid, erect, the styles short, rather thick, united at the base. Fruit 
enclosed in the unaltered perianth. Pericarp membranous. Seed erect, flat ; 
embryo circinate, the radicle usually inferior.— F. v. M. Ic. Sal. PI. 28 ; Rhagodia 
nitrariaeea, F. v. M. in Trans. Phil. Inst. Yict. ii. 73. 
Hab.: Recorded for Queensland by F. v. M. 
2. C. auricomum (golden-haired), Lindl. in Mitch. Trop. Austr. 94 ; Benth. 
FI. Austr. v. 159 ; Blue Bush. Erect and tall, more or less white 
or hoary all over, herbaceous and not spinescent. Leaves on rather 
long petioles, ovate or oblong, very obtuse, entire or rarely hastate with prominent 
basal lobes, mostly f to ljin. long. Flowers in little dense globular clusters 
along the branches of a terminal panicle, sometimes distinct and rather distant, 
sometimes crowded into dense spikes. Perianth-segments broad, concave, closing 
over the fruit. Stamens 5, shortly exserted. Ovary small, globular, contracted 
into a long neck or united base of the styles. Pericarp depressed-globose, 
membranous. Seed very flat, horizontal. Embryo annular. — Moq in DC. Prod,

This species undoubtedly comes near to some forms of C. album, differing in its entire more 
tomentrse leaves and larger flowers. It appears to be still more closely allied to and perhaps 
not really di-.tiuct from the East Asiatic C. acuminatum, Willd. — Benth. 
3. C. album (white), Linn.; Moq. in DC. Prod. xiii. ii. 70; Benth. FI. Austr. 
v. 159 ; Fat Hen. A tough annual usually erect, 1 to 2ft. high, of a pale 
green or more or less mealy-white, especially the flowers and the under side of 
the leaves. Leaves petiolate, the lower ones ovate or rhomboidal, more or less 
sinuate-toothed or angular, the upper ones usually narrow and entire. 
Clusters of flowers in short dense or interrupted spikes, simple or slightly 
branched, the lower ones axillary, the upper ones or sometimes nearly all in a 
long terminal panicle leafy at the base. Segments of the fruiting perianth 
broad, concave, somewhat thicker in the centre or keeled, contracted and united 
at the base, completely closing over the fruit. Stamens usually 5. Seeds all 
horizontally flattened, smooth and shining, the pericarp exceedingly thin. — 
C. lanceolatum, R. Br. Prod. 407 ; Moq. in DC. Prod. xiii. ii. 62 ; C. Brmmeanum, 
Roem. and Schult. Syst. vi. 275.

Tbe species is a very common weed in Europe and temperate Asia, and has spread as such 
over many other parts 'of the world. Whether indigenous or introduced uncertain.
