4. C. murale (of walls), Linn. ; Moq. in DC. Prod. xiii. ii. 69 ; Benth. 
FI. Austr. v. 160. A rather stout erect or decumbent much branched annual, 
from under 1ft. to nearly 2ft. high, usually green, but sometimes with a slight 
whitish meal on the young shoots. Leaves on long petioles, broadly ovate 
triangular or rliomboidal, deeply and irregularly toothed, 1 to above 2in. long. 
Flowers small, green or slightly mealy, the clusters in much-branched rather 
slender spikes, forming loose leafless cymes or panicles usually much shorter than 
or rarely as long as the leaves, almost all axillary, rarely lateral or terminal. 
Segments of the fruiting perianth broad, concave, somewhat keeled, closing 
over the fruit or nearly so. Stamens usually 5. Seeds all horizontally 
flattened, opaque or somewhat rugose, the margins thick and obtuse or thin 
and acute. Pericarp not readily separable from the seed. C. crosum, R. Br. 
Prod. 407 ; Moq. in DC. Prod. xiii. ii. 68 ; Hook. f. FI. Tasm. i. 313. 
Hab: Rockhampton, rare ; Brisbane and other towns. 
This is another European weed now widely dispersed over various temperate and warm 
regions of the globe. Whether indigenous or introduced uncertain. 
5. C. triangulare (triangular), Ii. Br. Prod. 407 ; Benth. FI. Austr. v. 160. 
Stems weak procumbent or straggling, extending sometimes to 2ft. or more, 
the whole plant green or with but little of white meal on the young shoots. 
Leaves on rather long petioles, from ovate to oblong or to broadly hastate in 
the typical form, obtuse or shortly mucronate, under lin. long, the upper 
ones often and sometimes all lanceolate. Flowers very small, in clusters or 
little cymes in a terminal interrupted spike or along the short distant branches of 
a slender terminal panicle, or the lower ones in the axils of the upper leaves. 
Perianth-segments broad and concave, sometimes closing over and covering the 
fruit, sometimes smaller and much contracted at the base. Stamen usually 1. 
Styles short. Seed flat, horizontal, about | line diameter, in a very thin 
membranous pericarp. — F. v. M. Ic. Sal. PI. 26 ; C. triijonon, Roem. and Schult. 
Syst. vi. 275 ; Moq. in DC. Prod. xiii. ii. 65. 
Hab.: Common in many localities. 
Var. stellulatum. Perianth-segments with a rather small concave lamina contracted at the 
base into a linear stipes (reduced to the somewhat prominent midrib). Leaves of the typical 
form. — Wallangarra, border of N.S.W. 
Var. angustifolium. Leaves linear-lanceolate or the lower ones lanceolate-hastate. Perianth 
of the typical form. — The common form in Queensland. 
6. C. ambrosioides (Ambrosia-like), Linn ; Moq. in DC. Prod. xiii. ii. 72 ; 
Benth. FI. Austr. v. 162. An erect much-branched annual of 1 to 2ft., not mealy 
but more or less glandular-dotted and strongly aromatic. Leaves lanceolate or 
oblong, acute or obtuse, the lower ones irregularly toothed or sinuate, contracted 
into a short petiole, from under lin. to above 2in. long, the upper ones smaller 
and entire, passing into small linear or linear-lanceolate acute petiolate bracts, 
all green on both sides, glandular underneath. Flowers very small and numerous, 
solitary or clustered in the axils of bracts which are either minute or leafy and 
longer than the clusters, the clusters forming more or less leafy slender interrup- 
ted spikes, arranged in a large leafy panicle occupying the greater part of the 
plant. Fruiting perianth about ^ line diameter, the lobes short, completely or 
almost completely covering the fruit. Seeds smooth and shining, all or almost 
horizontal. 
Hab.: Moreton Bay, F. v. Mueller ; Rockhampton, O'Shancsy. Common. Whether indi- 
genous or introduced uncertain. 
A common weed in southern Europe, northern Africa, and western Asia, and spread with 
cultivation over many parts of the World. 
7. C. carinatum (keeled), B. Br. Prod. 407; Benth. FI. Austr. v. 162. 
Stems much-branched and procumbent or prostrate at the base, ascending to from 
4 to 1ft. or more, the whole plant more or less glandular pubescent. Leaves on
