472 SUPPLEMENT. 



S. secundus, Greene, p. 171. Add localities, Marin Co., California, Conrjdon, Miss East- 

 wood, and Mendocino Co., Miss Eastwood. The type is pale-flowered, but S. jmlchellus, 

 Greene, Pittonia, ii. 225, scarcely differs except in its more deeply colored flowers. 



c. Calyx narrow : sepals hirsute : leaves obovate, coarsely toothed at the rounded summit, 

 cuneate to a narrow slightly auriculate base. 

 S. hispidus, Gkay, p. 171. Add locality, Fresno Co., California, Brandegee, Miss Eastwood. 

 = = Stem and foliage glabrous. 



a. Upper cauliue and floral leaves lance-linear to oblong-linear, acute or attenuate at the 

 apex, cordate or auriculate at the base. 



1. Flowers (very dark purple or almost black) on long slender pedicels (half inch in 

 length). 



S. niger, Greene, p. 170. 



2. Flowers subsessile : leaves all narrow, linear. 



S. barbiger, Greene, p. 170. Seeds often, perhaps always, wingless. 



3. Flowers very short-pedicelled : middle cauline leaves large, broad, ovate, amplexicaul, 

 obtuse ; upper narrow and acute. 



S. Bre"Weri, Gray, p. no. Add localities. Snow Mt., Lake Co., California, Mrs. Brandegee, 

 and Mt. Hepsidom, San Benito Co., Miss Eastwood. 



b. Upper cauline and floral leaves acutish, elliptic-oval or elliptic-lanceolate : cordate- 

 clasping at the base. 



S. liesperidis, Jepson. Low slender tortuous-branched annual : lower leaves unknown ; 

 the upper entire or sparingly toothed, acutely narrowed to a rounded cartilaginous-thick- 

 ened tip at the apex : flowers small and rather numerous, subsessile in slender flexuous 

 terminal racemes : calyx green, flask-shaped : narrow apparently white petals exserted and 

 recurved : posterior pair of longer filaments connate nearly to the summit, elongated, much 

 exserted and conspicuously recurved, purple : capsules narrow, ascending or falcate-spread- 

 ing, 2 inches in length; seeds scarcely or not at all winged. — Erythea, i. 14. By error 

 accredited to Bioletti on page 170 of present work. — Knoxville Grade to Lower Lake in 

 region of Clear Lake, California, Jepson, July, 1892. Near S. Breweri and S. tortuosus, but 

 probably distinct. 



c. Upper cauline and floral leaves oval to orbicular, not at all narrowed to the very obtuse 

 or rounded and abruptly apiculate apex, deeply cordate-clasping at the base : filaments 

 apparently variable, one pair said to be connate, yet in most flowers examined all distinct. 



1. Flowers small: sepals with tips erect or slightly recurved, obtuse or acutish but not 

 caudate-attenuate. 

 S. orbiculatus, Greene. Low profusely branched annual with short ascending axis only 

 2 or .3 inches long, much surpassed by the slender ascending branches : leaves rather small ; 

 the lower spatulate-oblong, obtuse, subentire or undulate-margined : the upper suborbicular, 

 usually rounded and not apiculate at the apex : pods falcate-recurved ; valves thin and toru- 

 lose. — Fl. Francis. 2.58. — Near Carson City, Nevada, Anderson, and in the Sierras of Cali- 

 fornia from Sta. Lucia Mts., Miss Eastwood, and Mono Co., Coville & Funston, to Shasta, 

 Brewer. A species of highly characteristic habit in well developed individuals, yet without 

 very strong technical characters. 



S. SUflPrutescens, Greene. Biennial or perhaps perennial, lignescent at the base, the 

 stout sparingly branched leafy axis becoming a foot or more in height : leaves much larger 

 than in the last, those of the stem 2 or .3 inches long : sepals erect or slightly reflexed : 

 flowers and fruit essentially as in the last preceding species. — Erythea, i. 147, & Man. Bay- 

 Reg. 16. — Hood's Peak, Sonoma Co., California, Bioletti. In habit very different from 

 5. orbiculatus, yet perhaps only a more robust and enduring form of it. 



2. Flowers larger : sepals caudate-attenuate, the tips conspicuously reflexed. 



S. tortuosus, KELLOGCr. Erect sparingly branched annual, 1 to 3 feet high : lower leaves 

 obovate-spatulate, undulate-toothed ; the upper suborbicular, but mostly with a short abrupt
