SAXIFRAGE FAMILY 123 



Kefs. — Saxifraga bryophoea Gray, Proc. Am. Acad. 6:533 (1865), type loc. Ebbetts Pass, 

 Alpine Co., 9000 ft.; Jepson, Fl. W. Mid. Cal. 269 (1901), ed. 2, 198 (1911), Man. 456, fig. 447 

 (1925). Spatulana bryophora Small, N. Am. Yl. 22:148 (1905). 



12. S. tolmiei T. & G. Alpine Saxifrage. Plants 2 to 5 inches high, the 

 stems leafy, diffusely branching, forming dense tufts ; leaf-blades linear, closely im- 

 bricated on the short branches, sessile, 3 to 5 lines long; cymes disposed in a corym- 

 bose panicle or close cluster; filaments dilated at the summit. 



High montane rocky slopes, 8500 to 10,000 feet : Sierra Nevada from Tulare Co. 

 to Tehama Co. and Mt. Shasta. North to British Columbia and southern Alaska. 

 July. 



The Californian representation of this species was long ago set off by Greene as distinct 

 under the name Saxifraga ledifolia. As var. ledifolia it was later characterized by Engler and 

 Irmscher as more robust than typical Washington plants of S. tolmiei and as possessing linear- 

 oblong leaves. While Californian plants are sometimes a little stouter, plants from Mt. Silliman 

 are as slender as plants from Mt. Adams, Wash. (Sulcsdorf 489) and are like them in leaf shape 

 and size. Nor, indeed, does other California material differ in any essential way from plants 

 inhabiting more northerly stations. Our specimens represent a graduated series extending from 

 California to Alaska with only a certain degree of apparently ecological variation.

Saxifraga sarmentosa L. f. Supplem. 240 (1781), type from Japan. Herbage and inflor- 

 escence pilose ; leaf -blades orbicular, crenate, white-veined above, reddish beneath ; corolla white, 

 pink-tinted, very irregular; petals shortly clawed, the 3 upper ovate, about % as long as the 

 2 lower ovate-lanceolate ones. — Garden plant from Asia, sparingly colonized in the Eedwoods 

 near Sebastopol, Sonoma Co. It spreads by slender runners. 



2. SAXIFRAGOPSIS J. K. Small 



Perennial herb with somewhat scape-like flowering stems and tufts of basal 

 leaves arising from scaly winter-buds terminating the branches of the woody root- 

 crown. Root-crown densely clothed with old persistent petioles and scales. Leaves 

 unifoliolately compound, the blades cuneate-obovate, dentate above the middle, 

 entire on the sides, jointed at base to the petiole. Flowers small, in a narrow 

 panicle. Calyx-lobes finally reflexed. Petals white, obovate, gradually narrowed 

 to a short claw, at length reflexed. Filaments subulate. Ovary adnate to the 

 calyx-tube at base, its carpels united to the middle or above, erect in fruit. — 

 Species 1. (Saxifraga and Greek opsis, resemblance.) 



1. S. fragarioides Small. Stems 4 to 8 inches high; herbage glandular-pubes- 

 cent; leaf -blades 1/2 to l^/^ inches long, disjointing roughly from the petiole in age; 

 petals 1 line long. 



Montane, on cliffs or rocky slopes, 5500 to 6500 feet : Salmon Mts. ; Scott Mts. ; 

 Marble Mt. North to southwestern Oregon. July.

3. JEPSONIA J. K. Small 



Perennial herbs with basal leaves and scapes from corm-like roots. Flowers 

 few in a cyme terminating a naked scape, appearing in the autumn before the 

 leaves. Leaf-blades round-cordate, crenate and shallowly crenate-lobed. Calyx 

 5-toothed, its tube short-cylindric, the base with a honey-bearing area within.
