flower. : 
SAXIFRAGACELJE. 
SAXIFRAGA VIRGINIENSIS, Micha. Fl. 1, p. 269; Torr. & Gray, Fl. 1, p. 571; Benth. Pl. 
Hartw. p. 311. Mountains near Oakland, California. The leaves are less toothed, and the 
petals broader than in the eastern plant, but in other respects there is little difference. Dr. 
Bigelow collected in Napa valley (May 5) an unusual state of this species, with large, thin, 
nearly entire glabrous leaves, and a very loose sparsely-flowered panicle; characters which 
may be owing to the plant having grown in a moist shady place. 8 i 
SAXIFRAGA INTEGRIFOLIA, Hook. Fl. Bor.—Amer. 1, p. 249, t. 86: var. foliis oblongo-lanceolatis, 
basi angustatis; cymis in paniculam elongatam sub-contractam dispositis ; floribus brevi- 
pedicellatis; calycis segmentis oblongis recurvis; petalis lineari—lanceolatis, obtusis, Swaraps 
near Santa Rosa, California; May 3. Plant 24-30 inches high ; leaves 2-3 inches long ; corolla 
apparently white. This variety has a strong resemblance to S. Pennsylvanica, The panicle 
remains contracted even in fruit. 
Hevcuera MICRANTHA, Dougl. in Bot. Heg. t. 1302; Torr. € Gray, Fl. 1, p. 579. Rocky 
ravines, Yuba, near Downieville, May 22 ; and shady hill-sides, N apa valley, California; May 5. 
The solitary specimen from the latter locality is leafy to the summit, and more hairy than is 
usual in this species. This accords with Hartweg's No. 1742, but it can hardly be H. pilosis- 
sima of Fischer and Meyer.
