234 LOASE.i;. 



or only sinuate-toothed : fl. usually clustered, not conspicuoTisly brac- 

 teate : calyx-lobes 2 — 5 lines long : petals obovate to oblanceolate, 

 rounded or acutish at apex, 4 — 8 lines long : filaments subulate-filiform: 

 capsule slightly clavate-dilated, % — 1 "^- long : seeds in 3 rows, angular, 

 minutely tuberculate, % line long. — Plains and foothills of the interior, 

 from the Sacramento southward ; also east of the Sierra. 



7. M. uitens. Loosely diffuse, the lower branches decumbent, 1 — 2 

 ft. long, all clothed with a glabrous very white shining bark ; leaves 

 few, the internodes elongated : fl. solitary in the upper forks, and some- 

 what chistered at the ends of the branches, 1 in. broad : petals oblong- 

 obovate, obtuse or emarginate : stamens short ; filaments subulate ; 

 anthers oblong : seeds tuberculate, sharply and very siniiously angled. — 

 Near Benton, Mono Co., W. H. Shockley; possibly perennial. 



8. M. pectiuata, Kellogg, Proc. Calif. Acad. iii. 40. f. 9 (1868). Stem 

 low and mostly simple, 4—8 in. high, clothed like the leaves with a rather 

 dense barbed pubescence : leaves rather deeply and closely pinnatifid : 

 fl. deep yellow, 1 in. broad ; petals mostly obcordate, with a minute cusp 

 in the sinus : stamens very many, half as long as the petals ; filaments 

 filiform, or slightly subulate-dilated at base ; anthers small, orbicular : 

 seeds unknown. — Marysville Buttes, Jepson, and southward along the 

 foothills of the Sierra. Possibly all the so-called M. gracilenta of the 

 interior of California may be of this very genuine species. It is a very 

 beautiful plant, resembling the next.

 i. 189 (1840). Bartonia aurea, Lindl. Bot. Reg. t. 1831. Slender, simple 

 or biishy-branched, 1 — 3 ft. high : leaves ovate to narrowly lanceolate, 

 2 — 3 in. long, from pectin ate-pinnatifid to coarsely toothed : fl. axillary 

 and terminal : calyx-lobes rather broadly lanceolate, }4 — M i^i- long : 

 fl. vespertine : petals obovate, abruptly acuminate or ciispidate, 1 in. 

 long or more, golden yellow : filaments many, very slender, unequal, the 

 longest almost equalling the petals ; anthers minute, oval : capsule 1 in. 

 long or more : seeds angular, tuberculate. — Common in the Mt. Diablo 

 Range, near Livermore, on Mt. Hamilton, etc., on dry open hillsides. 



* * Flowers large; petals 3 or 10; stamens very numerous, the outer peta- 



loid-dilated; seeds many, in double rows on the S placentx, horizontally 



flattened and winged. — Genus Nuttallia, Raf.

 t. 69 (1833), under Bartonia. Biennial, stout, branched above, 2 — 3 ft. 

 high ; stem white, scarcely roughened : leaves lanceolate, sinuate- 

 toothed, 2 — 8 in. long : fl. sessile on short branches, 3 — 4 in. broad, light 

 yellow, diurnal : calyx-tube naked ; segments 1 in. long or more : petals
