7. C. BoTRYS, Linn. Sp. PI. i. 219 (1753). BalriidiiDit aroiitaticiDii, 

 Sp.ach. Phaner. v. 299 (1836). Annual, erect, often widely branching, 

 1 — 2 ft. high, glandular-pubescent and highly aromatic : leaves ovate or 

 oblong, 1 — 2 in. long, sinuate-pinnatifid, the lobes often toothed : fl. 

 scattered in very numerous slender axillary cymose panicles : sepals 

 acute, loosely investing the fruit : pericarp persistent : seed ig line 

 broad, thick-lenticular, black and shining. — Frequent in the interior of 

 the State ; native of S. Europe, and commonly called Jerusalem Oak. 



8. C. ANTHELMiNTicuM, Liuu. 1. c. 220: Spach. 1. c. 298, under Ambrina. 

 Perennial, stems stoutish, decumbent, 1 — 2 ft. long ; herbage light green, 

 glandular-puberulent, pleasantly aromatic : leaves thin, oblong, narrowed 

 at base, obtuse, sinuate-serrate or sometimes remotely dentate, 1 in. 

 long or less : inflorescence a terminal leafless panicle of dense but 

 slender spikes : sepals not carinate, completely enclosing the fruit : seed 

 smooth and shining, obtusely margined. Not rare among the foothills 

 of the Sierra from Shasta Co. southward, by waysides. 



9. C. AMBROsoiDES, Liuu. 1. c. 219; Spach, 1. c. 297, under Ambrina. 

 Annual, erect or ascending, 2 -3 ft. high, deep green, glabrous or slightly 

 scabrous, the foliage occasionally puberulent : leaves oblong, attenuate 

 at each end, acutish, remotely sinuate-toothed or entire, the uppermost 

 and floral linear-lanceolate : inflorescence loosely spicate and leafy : 

 fruiting perianth completely closed : seed smooth and shining, obtusely 

 margined. — Very common by waysides and in waste lands at the out- 

 skirts of cities and villages along the seaboard ; said to be native of 

 tropical America, but in our district too hardy, flowering and fruiting all 

 the year round and becoming suffrutescent. It is less aromatic than 

 C. anthehninticum, and manifestly distinct from it, though there seem to 

 be natural hybrids between them where they meet.
