leaves sparingly puberulent, the bark becoming white, shining and 

 loose ; leaves lanceolate or narrowly oblanceolate, acute or acuminate, 

 narrowed to a petiole, usually denticulate ; spike erect or somewhat nod- 

 ding, elongated, few - many-flowered ; calyx-tube and the obovate 

 petals 1| -3" long ; capsule linear-fusiform, 8-15" long, subtetragonal, 

 1" wide at base, and attenuate upward to a narrow beak ; seeds 1" long 

 or more, linear, angled, densely cellular-pubescent under the micro- 

 scope. — Southern California and Arizona. 



* * Flowers yellow, turning green ; calyx-tube obconic ; capsules 

 linear, tetragonal, more or less contorted ; stems leafy throughout. 

 Annual or biennial. 



40. (E. cheiranthifolia, Hornem. Spreading with decumbent or 

 ascending stems, often 2° long or more, canescently pubescent ; leaves 

 thick, h - 2|' (often less than 1') long, broadly ovate to oblong or lan- 

 ceolate, the radical and lower cauline leaves spatulate or oblanceolate 

 with a slender petiole, the upper very shortly petioled, sessile or clasp- 

 ing, acute or obtuse, mostly entire, sometimes obscurely denticulate ; 

 calyx-tube 1 - 1|" long ; petals 3-4" long ; capsule 4-8" long, attenuate 

 upward, curved, subhairy ; seeds ovate-oblong, \" long, acute at base, 

 smooth. — On the sea-coast, near San Francisco and southward. Like 

 many other species, beginning to flower when very small. It is said to 

 have come originally from Chili, and Gay mentions it as occurring in 

 several provinces of that republic. There are no Chilian specimens in 

 our herbariums, but the California plant accords essentially with the 

 early figures and descriptions. 



Var. suffruticosa. ( (E. viridescens, Hook.) Woody at base and 

 perhaps perennial, densely hoary-tomentose or rarely glabrous ; leaves 

 mostly small, \ - V long, crowded ; flowers usually larger, the petals 

 4 - 9" long. — Sea-coast of Southern California, from Monterey to 

 Santa Barbara. 



41. CE. bistorta, Nutt. Rather stout, subdecumbent or ascend- 

 ing 1-2° high, branched from the base, simple above, somewhat hir- 

 sute, the leaves sometimes appressed-pubescent ; radical leaves spatu- 

 late to lanceolate, petioled, the cauline mostly sessile, ovate to narrowly 

 lanceolate, about 1' long, acute or acutish, often obtuse and clasping 

 at base, all denticulate or dentate ; calyx-tube 1 - 3" long ; petals 4r- 7" 

 long ; usually with a brownish spot at base ; capsules 4 - 9" long, acute- 

 ly tetragonal, 1" or more wide, subattenuate at base and narrowed
