 Currau, Bull. Calif. Acad. L 79 (1884). Stout, rather widely branching, 2 

 ft. high, glabrous below, sparingly hirsute above : inflorescence loosely 

 spicate : calyx-lobes ovate-lanceolate, abruptly acuminate : corolla 1 in. 

 long, deep or pale purple : achenes more or less perfectly sulcate on the 

 back, by oblitei'ation of the usual transverse ridges. — In Marin Co.,

 -H- Erect species, ivith branched inflorescence. 



6. S. Hickiiiaiii, Greene, Pittonia, i. 139 (1887). Stems tufted from 

 a woody-fibrous tap-root, 2 — 3 ft. high, leafy throughout, rough with a 

 stellate-hispidulous pubescence : lowest leaves orbicular, small, with 

 slight crenate lobes ; cauline larger, round-flabelliform, coarsely and 

 irregularly toothed around the semicircular margin, the petiole longer 

 than the blade : racemes numerous, axillary and terminal, few-flowered : 

 pedicels short, subtended by 3 filiform bractlets }4 i^- long : calyx-lobes 

 oblong-ovate, acuminate : corolla purple, 1 in. long : achenes nearly 

 orbicular, 1 line long, marked on the back by scattered transverse short 

 and shaiTJ ridges. — A remarkable species, in aspect qiiite unlike any 

 other known, but in character a true Sidalcea Canons of the Salinas 

 valley, Hickman. 



7. S. Oreg-aua, Gray, PL Fendl. 20 (1849) ; Greene, Bull. Calif. Acad. 

 i. 77 ; Nutt. in T. & G. Fl. i. 234 (1838), under Sida. Sida malvxflora, Lindl. 

 Bot. Beg. t. 1036 (1826), not of DC. Stems solitary or few from the root, 

 2—6 ft. high, naked and paniculately branched above, leafy below ; 

 inflorescence stellate-tomentose, peduncles and lower part of stem 

 sparingly hirsute, the plant otherwise glabrous : lower leaves orbicular, 

 7 — 9-lobed, the cuneate-obovate lobes 3-cleft at summit ; upper 7 — 9- 

 parted, narrowly and deeply cleft : spicate racemes usually dense but 

 elongated : calyx-lobes broadly ovate, acute, not longer than the tube : 

 corolla ^2 — 1 in. long : achenes small, straight (semiorbicular), slightly 

 beaked, smooth and glabrous, 1 line long. — In the northeastern counties 

 of the State, doubtless within our limits, but more common in Oregon. 

 It is also to be sought in the Coast Range ; for a fruiting spike only, 

 evidently of this species, was collected by Mr. V. K. Chesnut in Sonoma 

 Co., near Santa Rosa, in 1887. 



8. S. spicata, Greene, Bull. Calif. Acad. i. 76 (1885) ; Gray, Proc. Am.
