base, the branches 6 —12 in. long ; herbage pubescent, glandular and 

 aromatic : leaves ovate, oblong or lanceolate, 1 in. long or less, sinuate- 

 pinuatifid, deep green above, paler beneath and somewhat glaucous : fl. 

 glomerate in the axils : stamen 1 : fruiting perianth only partly enclosing 

 the vertical utricle ; segments obtusely carinate, or at least thickened on 

 the back : seed black and shining, the margin acute. — Introduced from 

 Australia, and frequent in the foothills of the Sierra, at lone, etc.

11. C. Califoriiicuiii, Wats. Bot. Calif, ii. 48 (1880) ; also Eev. Chenop. 

 101 (1874), under Bliliim. Stems several from a long fusiform perennial 

 root, stout, decumbent, mostly simple, 1 — 8 ft. high ; herbage light but 

 rather dull green, the young parts a little mealy : leaves broadly 

 triangular-hastate, 2 — 3 in. long, truncate or with sinuses at base, acumi- 

 nate, sharply, unequally, and often deeply sinuate-dentate : tl. in dense 

 clusters in a long simple terminal "spike : perianth campanulate, rather 

 deeply .5-toothed, enfolding the utricle only loosely : pericarp persistent: 

 seed somewhat compressed, % — 1 line broad. — Common both on the 

 seaboard and in the interior ; the native American counterpart of the 

 Old World ('. Bonus ITenrictis^ to which it was in early days referred. 



12. C. grlaucurii, Linn. Sp. PI. i. 220 (17.53); Koch, Fl. Germ. 608 

 (1837 j, under Bliiam. Annual, stout and rather fleshy, erect with 

 ascending branches, % — 1 ft. high : leaves ovate to oblong-lanceolate, 

 1 in. long, obtuse, petiolate, remotely and rather coarsely dentate, 

 glabrous and green above, paler and mealy beneath : fl. in axillary 

 spiked clusters : perianth small, with rounded lobes, not quite concealing 

 the vertical, or as often horizontal utricle. — In the Sviisun marshes ou 

 elevated and dry ground ; apparently indigenous, though possibly intro- 

 duced from Eur(jpe, where it is a common barnyard weed. 



2. ROUBIEVA, Mo(juin. Herb perennial, glandular, heavy-scented, 

 with alternate pinnatifid leaves, and flowers few or solitary in the axils. 

 Perianth bractless, deeply campanulate, 3— 5-toothed, at length saccate 

 and contracted over the fruit, 3 5-nerved, net-veined. Stamens 5, 

 included. Styles 3, somewhat lateral, ex.serted. Pericarp membranous, 

 glandular-dotted, deciduous. Seed vertical, lenticular ; embryo annular 

 around a coi>ious albumen.

 PI. i. 220 (17.53), under Clienopodinm. Stems several from an oblong or
