CRUCIFEK^. 269 



mento, Sept. 1891, Jepson ; an uncommonly well marked species in the 

 characters of its fruit. The name has a double application, being sug- 

 gested by the reticulation of the valves as well as by that of the partition. 



IB. BARBAREA, Dodonieus (Wintek Cress). Erect branching glab- 

 rous biennials or perennials of rather low stature, with angular stems 

 and more or less distinctly lyrate or i)innatifid leaves. Flowers rather 

 small, bright yellow. Sepals equal at base, erect. Pods linear, either 

 somewhat flattened, or more distinctly quadrangular, pointed; valves 

 more or less carinate. Seeds in 1 row, oblong, turgid, marginless; 

 cotyledons oblique. 



1. B. vulgaris, R. Br. Hort. Kew. iv. 199 (1812). Erysimum Barhnrea, 

 Linn. Sp. PI. ii. 660 (1753); Crantz, Austr. 54 (1792), under Sisymbrium. 

 Stoutish, 1 — 3 ft. high; herbage bright green and glossy: leaves mostly 

 radical, the very lowest sometimes simple, oftener with 1 or more pairs 

 of relatively small lobes below a very large terminal one; cauline either 

 simple and toothed, or pinnately parted: fl. 2 — 3 lines long: pods 1 — 2 

 in., erect, ascending, or even arcuate-spreading, flattened, or more or less 

 4-angled; pedicels always short and stout. — Common in moist open 

 ground, or in shady places along streams; varying excessively in foliage 

 and fruit, and perhaps embracing several good varieties or subspecies. 



17. ERYSIMUM, Dioscorides. Biennials or perennials, ours stout, 

 simple or with few branches. Leaves narrow, entire or runcinately 

 toothed, not clasping. Flowers large, yellowish or orange. Sepals 

 erect, one pair strongly gibbous at base. Petals with long claw and flat 

 blade. Anthers sagittate. Pod 4-angled or flattened, and the valves 

 merely nerved. Seeds in 1 row, not margined; cotyledons incumbent or 

 oblique. — It is conceded on all sides that there is no valid distinction 

 between Erysimum and Cheiranihus, and each of our two species has at 

 one time or another been referred to both genera. 



1. E. asperum, DC. Syst. ii. 505 (1821); Nutt. Gen. ii. 69 (1818), under 

 CheiraiUhus. Canescent with short straight closely appressed hairs: 

 stems solitary, rarely with a few branches above, 1 — 3 ft. high, angular: 

 leaves narrowly spatulate or oblanceolate, entire or runcinate-toothed, 

 1 — 3 in. long: fl. large, fragrant: sepals narrow, 4 — 6 lines long: petals 

 from light yellow to deep orange, 8 — 12 Hnes long: pods slender, 

 spreading, quadrangular, commonly 3 — 4 in. long, 1 line wide, beaked 

 with a stout style. — Common in the mountains almost everywhere, but 

 chiefly at some distance from the seaboard; usually with orange-red 

 petals in the Sierra; a less tall form, with pale corollas, abounds in the 

 Mt. Diablo Range, and may prove distinct. This is probably the E. 

 grandijiorum, Nutt., referred to the next in the Bot. State Survey.
