whose remarkable peculiarities of floral structure exclude it from Draha 

 and link it very closely with Athysanus. 



6. ATHYSANUS, Greene. Habit and character of the preceding, 

 save that the very small orbicular and straight pods are 1-celled and 

 l-seeded.

 (1837), under Thysanocarpus; probably including T. oblongifoiius, Nutt. 

 Stems filiform, branching from the base, the branches mostly ascending, 

 unilaterally racemose throughout: leaves few, ovate, sparingly toothed, 

 3^ in. long: fl. minute, often apetalous: pods lenticular, more or less 

 uncinate-hispid, scarcely a line long, rather acute at base; style very 

 short. — Common on hillsides throughout western California. Mar., Apr. 



7. CAMELINA, RuelUus. Erect herbs, sparingly branching, with

 wnAev Myagrum. Pubescent, ig — 2 ft. high: leaves lanceolate, sagittate 

 at base, nearly entire: pods pyriform with acute base. — Formerly 

 extensively cultivated in Europe for the oil of its seeds; now become a 

 weed in fields of grain in many countries; not yet well established in 

 California, at least in our part, but found in a field at Berkeley by Mr. 

 Chesnut. in 1887. 



8. SMELOWSKIA, C. A. Meyer. Dwarf alpine perennials, with 

 pinnatifid leaves, and white or pinkish flowers. Sepals equal, somewhat 

 spreading. Petals entire. Silique short, attenuate at each end, commonly

 Seeds in 1 row, oblong, not margined; cotyledons incumbent. 



1. S. caly cilia, C. A. Mey.; Ledeb. Fl. Alt. iii. 170 (1831); Desv. Journ.

 under Lepidurn. Cespitose, stoutish, 2 — 6 in. high, white-tomentose to 

 almost glabrous; leaves mainly radical, with long slender petioles, 

 pinnate or pinnatifid; segments linear to oblong, entire or sparingly 

 lobed; calyx villous: petals 2 lines long: pod }^ — }4 ^^- ^ong, a line 

 wide, 4-angled, varying to almost flat, attenuate at each end, beaked
