 ventral base, the small and soft glabrous apiculatiou evanescent ; some soft thin processes 

 left on the receptacle. — Gray in Benth. PI. Hartw. 300, PI. Pendl. 20, & Proc. Am. Acad, 

 xxi. 409. aS. teneUa, Greene, 1. c. partly. — California, with S. hirsuta in the valley of the 

 Sacramento, also on dry hillsides; first coll. by Hartweg ; also from Colusa Co. to Mariposa. 

 Smaller-flowered forms reach extreme in 



Var. tenella, Gray. Slender and more branching, much smaller-flowered : petals 

 quarter to third inch long, lighter-colored. — Proc. Am. Acad. xxii. 286. 5. tenella, Greene, 

 Bull. Calif. Acad. Sci. i. 7. — On the Little Chico, Butte Co., Mrs. Austin. Anthers abortive 

 and styles very long in some flowers. 



§ 2. Perennials, strong-rooted, spring- or mostly summer-flowering, with 

 flowers in naked (either single or paniculate) terminal spikes or racemes : exte- 

 rior phalanges closely approximate to the interior or terminal stamens at summit 

 of the column : petals seldom at all erose or denticulate. 



* Phalanges manifest, at least the exterior series, but the membrane often more or less 

 cleft or parted : leafy-stemmed (except in S. parvijiora, var. '? Thurberi) : some or all 

 of the cordate-orbicular lowest leaves barely crenate-lobed or incised ; the upper cauline 

 always deeply parted. 



H— Corolla uniformly white : anthers bluish. 

 S. Candida, Gray. Glabrous or almost so : stem 2 or 3 feet high from somewhat creeping 

 rootstocks, leafy to the spiciform inflorescence : radical leaves obtusely lobed or crenate- 

 incised ; cauline (4 to 8 inches broad) 5-7-parted and divisions 2-3-lobed at apex, or upper- 

 most 3-5-parted into lanceolate entire divisions: calyx-lobes deltoid: petals half inch or 

 more long : carpels nearly glabrous and smooth (or slightly puberulent and in age obscurely 

 reticulated on the sides), thin. — PI. Fendl. 20, 24, & Gen. 111. ii. t. 120, f. 9 (androecium) ;

-t— -1— Corolla rose-color or mauve-purple, rarely a white variety. 

 ++ Herbage cinereous with a short and soft several-rayed stellular pubescence, no hirsute or 

 hispid hairs. 



S. Californica, Gray. Stems 2 or 3 feet high, erect, bearing a simple loosely-flowered 

 spiciform raceme : lower leaves 2 or 3 inches broad : calyx-lobes 3-5-nerved, ovate-deltoid 

 becoming deltoid-lanceolate : petals inch long : young carpels sparsely hispidulous-puberulent 

 on the back : phalanges of outer series broad and short, truncate, 4-5-antheriferous on short 

 filaments. — PI. Fendl. 19, & Proc. Am. Acad. xxii. 286. Sida Ca/ifontiai, Nutt. in Torr. & 

 Gray, Fl. i. 233. — Santa Inez Mountains near Santa Barbara, California (abundant in 

 Mission Canon and Cassitas Pass) ; first coll. by Nntfall. 



++ ++ Herbage green, at least not cinereous : coarser pubescence when present of simple or 

 geminate or few-rayed stellular hairs : species difficult to discriminate, apparently more 

 or less confluent. 



= Mature carpels when dry rugulose-reticulated, at least on the sides, mostly on the back 

 also (sometimes smooth or nearly so in S. Oregana) : petals (except in S. Oregana & S. 

 parviflora) half inch to full inch long. ,, 



S. malvseflora, Gray. Hirsute or stems and petioles even hispid with few-rayed and some 

 simple spreading hairs, but hardly any minute stellular pubescence : stems ascending or 

 erect from decumbent base, 8 inches to 2 feet high (or rarely more) from a thick stock or 

 root, simple and bearing simple loosely few-many-flowered spiciform racemes : petals about 

 inch long : lobes of fructiferous calyx from deltoid-ovate to lanceolate : mature carpels 

 lightly rugulose-reticulated, when young almost smooth. — Proc. Am. Acad. xxi. 409, & xxii.
