Eucnide lobata, Gray, PI. Lindh. 2, p. 192. Rocky ravines of the Colorado, near the con¬ 
fluence of Williams’ River, in western New Mexico. The specimens were winter vestiges, with 
good fruit of the preceding season.

ary 20.

August. 
Mentzelia (Bartonia) nuda, Nutt.; Torr. & Gray , FI. 1, p. 534. On Elm creek and the 
False Washita ; August. Denuded plains of the Upper Canadian ; September. 
Mentzelia (Bartonia) multiflora, Nutt. PI. Gamb. p. 180 ; Gray, PI. Wright, p. 74. Rocky 
canons, from the Llano Estacadoto Galisteo, New Mexico ; October. 
CRASSULACEiE. 
Sedum Wrightii, Gray, PI. Wright. 1, p. 76. Sandia mountains, New Mexico ; October. 
A dwarf and condensed state. 
Sedum spathulifolium, Hooh. FI. Bor.-Amer. 1, p. 227 ; Torr. & Gray, FI. 1 , p. 559. Hill¬ 
sides and rocky places, Napa valley, California ; May 5. Stems ascending, simple, or sparingly 
branched, throwing off from the base prostrate sterile runners or offsets, which bear a rosulate 
tuft of leaves at the extremity, and strike root. 
Eciieveria lanceolata, Nutt, in Torr. & Gray, FI. 1 ,p. 561. Rocks and hill-sides, Sonoma, 
and Knight’s Ferry, Stanislaus river, California ; May 3-9. The leaves vary in form, from 
lanceolate to obovate. The pedicels are from one-third to more than half the length of the 
flower. 
SAXIFRAGACEiE. 
Saxifraga Yirginiensis, Michx. FI. 1, p. 269 ; Torr. & Gray, FI. 1, p. 571; Benth. PI. 
Hartio. 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. 
Saxifraga integrifolia, Hooh. FI. 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. Swamps 
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. 
Heuciiera micrantha, Dougl. in Bot. Reg. t. 1302; Torr. & Gray, FI. 1 , p. 579. Rocky 
ravines, Yuba, near Downieville, May 22 ; and shady hill-sides, Napa 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.
