CRUCIFEItiE. '259 



Wats., not Kell. Near tlie preceding, but low (}4 — IM ft. bigh), diffusely 

 brancbed from the ba.se: lowest leaves round-obovate, very obtuse or 

 even truncate, crenately or more remotely and repandly toothed, abruptly 

 narrowed to a petiole as long as the blade; middle cauline obovate- 

 spatulate, auricled jmd clasping; uppermost orbicular, mostly entire^ 

 ol)tuse: sepals purple, 2- 3 lines long, acute but not acuminate, at length 

 petaloid-dilated, undulate and whitish at the recurved tips: stamens in 

 3 unequal pairs, but the upper pair much the longest: torus dilated: 

 pods 2 in. long, falcate on ascending pedicels, strongly torulose: seeds 

 wingless, though sometimes distinctly but very narrowly margined. — 

 Common in the Sierra from Donner Lake northward; also on Mt. 

 Diablo, McLean. Usually mixed with S. torluosus in the herbaria, from 

 which its dissimilar habit, and very different floral structure well dis- 

 tinguish it. But it is the " n. 1 " of Gray's *S'. Bretreri, and by modern 

 rules would retain that name; but Dr. Gray's description was drawn 

 wholly from his ns. 2 and 3; hence I continue that ixse of S. Breweri 

 which the specific character warrants. 



10. S, (liversifolias, Wats. Proc. Am. Acad. xvii. 363 (1882). Erect, 

 slender, branching above, l^o ft. high, glabrous: cauline leaves pinnately 

 divided with 1 or 2 pairs of narrowly linear lobes, the upper nearly or 

 quite entire, those of the branches broadly cordate, clasping and entire, 

 )^' in. long or less: racemes few-flowered: sepals pale, 2 — 3 lines long: 

 blade of petals rather broad, purple-veined: pods very narrow, 1% — ^}>i 

 in. long, strongly reflexed. — Apparently a local species of the Cosumne 

 Creek in Sacramento Co., Rattan. 



•i— -i— One or tiro pairs of .stamens vilh filaments connate; petals unequal, 



the upper pair larger and parallel, the lower smaller and 



divergent; plants all annual. 



-J— Calyx not manifestly irregular.

(1864:), as to descr., and numbers "2" and "3" of sj^ecim. (seen. 9 supra). 

 Branched from the base, 1 — 2 ft. high, leafy at base chiefly: leaves 

 broadly ovate or obovate, acute or acuminate, sessile, dentate, 1—3 in. 

 long, thickish; the cauline reduced and bract-like, lanceolate, acuminate, 

 entire or denticulate, somewhat auricled and clasping: racemes elon- 

 gated and the fl. scattered, short-ijedicelled: sepals purple, acuminate, 

 glabrous or pubescent: petals exserted: 2 pairs of filaments connate, 

 those of the uppermost and longest joined to the summit, and the anthers 

 reduced to less than half the size of the others: pod IVg — 2i-2 in- long, 

 less than 1 line wide, erect or ascending, mostly somewhat incurved. — In 

 the Mt. Diablo Range southward, on Mt. San Carlos, etc. Apparently 

 not collected since Brewer's time, and the district is a neglected one.
