The species is common in many parts of Europe and temperate Asia, and occurs here and there in other parts of the globe.
C. littorale. Moq. in DC. Prod. xiii. ii. 65, described from a specimen of Caley's in the Paris Herbarium, which I have not seen, may, from the character given, be a form either of this species or of C. album.
SECT. 3. BOTRYOIS, Moq. — Glandular aromatic herbs or undershrubs, not mealy. Seeds all or nearly all horizontal.
*8. C. ambrosioides, Linn.; Moq. in DC. Prod. xiii. ii. 72. An erect much-branched annual of 1 to 2 ft., not mealy but more or less glandular-dotted and strongly aromatic. Leaves lanceolate or oblong, acute or obtuse, the lower oues irregularly toothed or sinuate, contracted into a short petiole, from under 1 in. to above 2 in. 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 interrupted spikes, arranged in a large leafy panicle occupying the greater part of the plant. Fruiting perianth about ½ line diameter, the lobes short, completely or almost completely covering the fruit. Seeds smooth and shining, all or mostly horizontal.

W. Australia, Drummond, n. 207.
A common weed in southern Europe, northern Africa, and western Asia, and spread with cultivation over many parts of the world. It is probably introduced only into Australia as suggested in R. Brown's notes, and on that account omitted in his Prodromus.

9. C. carinatum, R. Br. Prod. 407. Stems much-branched and procumbent or prostrate at the base, ascending to from ½ to 1 ft. or more, the whole plant more or less glandular-pubescent. Leaves on long petioles, ovate or oblong, obtuse, coarsely sinuate-toothed, usually rather thick and rugose, glandular-scabrous on both sides, ½ to 1 in. long, the upper floral ones often much reduced, and sometimes all the leaves almost orbicular and small. Flowers small, in dense globular clusters in almost all the axils, the upper ones sometimes forming interrupted more or less leafy spikes. Perianth-segments erect, incurved,
