260 CKUCIFER^. 



widely braucbing, 1 — 1}{ ft. bigb, pubescent or glabrous: cauline leaves 

 linear, entire, scarcely auriculate: fl. svibsessile, 3 lines long: sepals 

 greenisb, the rather acuminate tips becoming whitish, petaloid and 

 recurved, the whole calyx commonly bristly-hairy, but often glabrous: 

 petals white: filaments dark purple, the three pairs very unequal, the 

 uppermost connate almost to the summit, their anthers much reduced 

 and seemingly sterile: pods 1 — 2 in. long, narrowly linear, recurved. — In 

 Lake Co., Simonds, and common in Napa Co., at Miravalle near St. 

 Helena, Greene. 



•M- •!-+ Calyx irregular, three sepals more or less connivent behind the upper 



petals, the fourth separated from these and somewhat dejlexed; 



1 pair of filaments connate. 



13. S. uiger, Greene, Bull. Torr. Club, xiii. 141 (1886). Branching 

 loosely from near the base and above, 1—3 ft. high, glabrous, glaucous: 

 leaves linear, 2 — 3 in. long, the lowest with narrow pinnate gland-tipped 

 lobes or teeth, the upper entire, auriculate-clasping: racemes loose, 

 flexuous: pedicels ascending, 1 in. long: calyx 3 lines long, of a very 

 dark metallic shining purple; sepals ovate-cymbiform, the 3 l^pper 

 slightly separate from the lowest, and connivent at apex: blade of petals 

 very slender, white: upper pair of filaments connate almost throughout, 

 their anthers small and sterile: pod 2 in. long, erect or ascending, nearly 

 straight: seed narrowly winged.- Hills above the ferry lauding at 

 Tibui'on; found only by the author, in April and June, 1886, now 

 seemingly extinct there, and not elsewhere detected. 



14. S. albidiis, Greene, Pittonia, i. 62 (1887). Stouter than the last, 

 equally glabrous and glaucous, even the cauline leaves with callous- 

 tipijed prominent teeth, the base sagittate-clasping: racemes not flexuous: 

 pedicels short: sepals 3 — 4 lines long, white, with purple base: petals 

 % in. long, the lamina ample, crisped, white, with purple veins: upper 

 pair of filaments united to the tip, their anthers small but polliniferous: 

 fr. unknown. — On hillsides not far from San Jose, Sister Anna Raphael, 

 Mr. Rattan. A handsome species, in floral structure quite distinct from 

 S. niger, to which it is most related. 



15. S. Mildredae. Slender, much branched from the base, 1 — l}^. ft. 

 high, more or less pilose-hispid: lower leaves coarsely and sinuately 

 toothed; cauline linear-lanceolate, entire, clasping: racemes somewhat 

 flexuous, not secured: fl. small, very dark metallic-purple: petals with 

 small, slenderly attenuate white-margined purple blade: upper pair of 

 filaments almost wholly united, their anthers reduced to mere rudiments 

 and closely approximate, the other 4 stamens much shorter and little 

 unequal: pods 3 in. long, slender, arcuate-spreading on the short pedi- 

 cels: seeds oval, the upper half narrowly margined. — Common on Mt. 

 Hamilton; dedicated to Miss Mildred Holden, in whose herbarium the
