calyx large, enclosing about 7 large, much depressed, dis- 

 tinctly reticulated carpels. — PI. Fendl. 20. Brewer & Wat- 

 son, Bot. Cal. I. 84. 



Abundant in all parts of California lying near the sea, 

 doubtless also in like situations to the northward; albeit the 

 few specimens which have come to us from Oregon, bearing 

 this name, are of a quite distinct species. The best marks 

 of this one are the stout, decumbent stems and broad calyx, 

 with correspondingly large, depressed carpels. 



-*"»- -i-5- Pubescence of two kinds; hirsute and stellate. 



S. spicata. 



Equably hispid-hirsute throughout, the hairs simple and 

 not deflexed, stellate pubescence sparse, mostly confined to 

 the under surface of the leaves, and to the calyx, where it is 

 minute : stems 2 feet high, strict and simple, or with a few 

 short branches above : lowest leaves orbicular, sinus narrow 

 or closed, lobes and teeth shallow and well rounded; cauline 

 parted into 7, variously incised, or often linear, entire seg- 

 ments : raceme short, spicate-crowded : petals deeply notch- 

 ed, about J inch long, pinkish: pedicels very short: calyx 

 thin, very hairy, its lobes ovate, acute or acuminate: carpels 

 small, depressed, pubescent but not reticulate. — Cisco, 

 Sierra Nevada, Cal. 1870. Dr. Kellogg. Also from near 

 Donner Lake, 1883, Mrs. Curran. 



The herbage of this species is of a peculiar, light green, 

 and is of a thinner texture than in the other members of the 

 perennial group. It may or may not be the Callirhoe spicata 

 of Kegel, neither the figure of which, nor any description, 

 has been accessible to me, but no other Sidalcea has its ra- 

 cemes condensed into the appearance of a short spike, if we 

 except the annual species at the end of this synopsis. 



S. campestris. 



Bristly hairs of the stem abundant, forked from the very 

 base and deflexed: leaves soft beneath with a stellate pubes-
