S. ambigua, Gray. Less leafy, a foot to a yard high, tomentulose-canescent : leaves 

 crenulate-toothed : inflorescence more racemiform : petals rose-color, varying to white, half 

 inch to inch long : calyx 4 to 6 lines long, with acute or acuminate lobes surpassing 

 the moderately depressed fruit : carpels reniform-oblong, commonly 3 lines long (deciduous 

 and free at maturity). — Proc. Am. Acad. xxii. 292. <S'. Emoryi, Gray, Bot. Ives Rep.

S. suLPHUKEA, Watson, Proc. Am. Acad. xi. 113, 125, of Guadaloupe Island off Lower 

 California, is a peculiar pale yellow-flowered species of this division, with habit of the original 

 S. Cisplatina, St. Hil. 



== = Densely tomentose : the leaves pannose and calyx thickly woolly. 



S. Lindheimeri, Gray. Stems decumbent, a foot or two long : leaves round-cordate 

 (larger 2 inches long), very obscurely if at all lobed, irregularly or doubly crenate : flowers 

 more or less racemose at the ends of branches : calyx nearly half inch long : corolla rose-red, 

 the petals half inch long : mature carpels glabrous, oblong-reniform, much compressed, 2 

 lines long, narrowed in the middle; lower half strongly reticulate- rugose; smooth upper 

 half similarly rounded, commonly empty: ovules 2 or 3. — PI. Lindh. pt. 2, 162; AVats.

++++++ Leaves undivided, more or less lanceolate, not rarely subhastately 3-lobed : 

 pubescence close, cauescent. 



S. hastulata, Gray. A span to a foot high, with ascending stems leafy to the top : leaves 

 slender-petioled, inch or two long, obscurely toothed or entire on the margin, some lanceo- 

 late or oblong with cuneate or truncate base, some with a pair of short either ascending or 

 diverging lobes near the base, rarely with broader subcordate base : flowers few, mostly 

 slender-pedicelled : petals orange-red, half inch long : calyx with triangular-lanceolate lobes 

 surpassing the slightly depressed fruit : mature carpels 3 lines long, ovate and with deep 

 reniform ventral excision, tipped with small deciduous cusp, often 2-seeded, the smooth 

 upper longer than the rugose-reticulated lower portion. — PI. Wright, i. 17, & ii. 21 ; Wats.

S.* subhastata, Coulter. Much like the last preceding species but usually lower and 

 frute.scent : leaves smaller, thicker, very rugose and with somewhat coarser tomcntum : 

 flowers few, borne in the upper axils, somewhat smaller Jind more deeply colored than in the 

 preceding: pedicels mostly only a line or two long: carpels (ace. to Coulter) without any 

 cusp at the tip. — Contrib. U. S. Nat. Herb. i. 32, ii. 38. — W. Texas, Thurber, Haiwrd, 

 Nealley ; ? Mimbres Mts., New Mexico, Wright; Arizona, Touwey. (A form from Coahuila, 

 Palmer, scarcely differs except in its larger flowers. ) 



* * Fruit little or not at all depressed: carpels 2-3-ovulate, l-3-.seeded, mostly oblong and 

 with some ventral excision, disposed to dorsal as well as ventral dehiscence, after separa-

 S. Mnnronnn, Coville, Contrib. U. S. Nat. Herb. iv. 74, as to no. 6.34, appears also to be S. ambigua. 



* Mr. S. B. Pari.'^h of San Bernardino, California, has called attention to the fact that there is a 

 purple-flowered form of S. ambigua at Palm Sprinfjs, S. California. The species also shows consider- 

 able variation in the size of flowers, density of inflorescence, shape and pubescence of leaves. But 

 these distinctions cannot as yet be correlated for a satisfactorj' specific or even varietal subdivision.
