 ovate, cordate-clasping, entire; petals yellowish; pods erect, linear, elongated. — 

 Introduced from the east ]\Iediterranean region, a waif in waste places : Upland

11. BARBAREA R. Br. 



Perennial herbs similar to the yellow-flowered Nasturtiums. Stem angular. 

 Leaves lyrate or pinnatifid. Flowers yellow. Stamens 6, distinctly tetradynam- 

 ous. Pod linear, somewhat quadrangular, abruptly tipped by a short style, the 

 valves strongly 1-nerved or carinate. Seeds in 1 row in each cell, turgid, not 

 margined. — About 7 species, temperate zones. (Named after St. Barbara.) 



1. B. orthoceras Ledeb. Winter Cress. Stem erect, rather stout, 10 to 16 

 inches high; herbage glabrous; blades of basal leaves elliptic, sometimes cordate 

 at base, % to 2 inches long, with or without small supplementary lobes borne 

 along the petiole; blades of cauline leaves similar, pinnatifid, with the terminal 

 lobe largest and often oblong-lanceolate; raceme terminal and solitary or with 

 several from the upper axils; petals narrowly obovate or oblanceolate, the blade 

 scarcely narrowed into a claw, about 3 lines long, twice or nearly twice as long as 

 the yellow sepals ; pods somewhat crowded, erect and appressed or strongly ascend- 

 ing) % to 1 inch long, % line wide, the beak l^ to % line long. 



Along streams or in woods in the high mountains, 9500 to 12,000 feet : Sierra 

 Nevada from Tulare Co. to Fresno Co. North to Alaska, thence east to Labrador; 

 n. Asia; n. Scandinavia (aec. Fernald). July. 



Geog. note. — While mainly or wholly absent from the deserts and the valleys, Barbarea ortho- 

 ceras (including its variety) is in California vridely distributed in the motmtain ranges and the 

 foothills, not only in the Coast Eanges but in the most primitive and unchanged portions of the 

 Sierra Nevada at middle and high altitudes. It is, judged by the nature of the habitat and the 

 associated indigenous species, very certainly, we think, a native plant. We may add that it is 

 also found on the highest and most remote peaks in an alpine form, as on Mt. Whitney, where its 

 decumbent stems, 2 to 4 inches long, bear flowers vdth the sepals slightly thickened at apex. The 

 typical form of the species is apparently somewhat uncommon in California and is confined to the 

 high Sierra Nevada ; in almost all of our specimens the racemes are more or less pathogenic.
