BOTANY. 85 
FRAGARIA vesca, Linn.; Torr. € Gray, Fl. 1, p. 448. San Antonita, New Mexico, October. 
Ravines on the Yuba, near Downieville, May 22, and mountains near Oakland, California ; 
April 5. 
FRAGARIA CHILENSIS, Eich. ` Torr. € Gray, .ا‎ c. Near San Francisco; April 3. 
Russ Nurxanus, Mogino; Lindl. Bot. Heg. t. 1368; Torr. & Gray, Fl. 1, p. 450. Corte 
Madera, California, April 10. 
RuBus vote, Cham. & Schlecht. in Linnea, 2, p. 10? Near San Francisco; April 3. 
Stems long and apparently prostrate. Leaves (of flowering specimens) about an inch and a 
half in length and breadth, strongly 3-lobed, a little pubescent on both surfaces when young. 
Flowers smaller than the species is described to have. Sepals ovate-lanceolate, with a long 
subulate (not foliaceous) point. Petals white, a little longer than the calyx. 
RuBus LEUCODERMIS, Dougl.; Torr. & Gray, Fl. 1, p. 454? Leroux's spring, foot of San Fran- 
cisco mountain, New Mexico; December. Prickles numerous, slender, short and somewhat re- 
curved. Leaves mostly pinnately 5-foliolate, very white underneath, much smaller than usual. 
Peduncles 5-6-flowered. The specimens are imperfect, the plant having been gathered late in 
the season. 
RuBus URSINUS, Cham. & Schlecht. in Linnea, 2, p. 11; Torr. € Gray, Le R. Menziesii, 
Hook. Fl. Bor.-Am. 1 p. 141; Hook. & Arn. Bot. Beech. p. 140. Ravines and low grounds 
near Punta de los Reyes; April 17. A showy species, with large red flowers. The obovate 
petals are 7 or 8 lines long, much larger than they are said to be by Chamisso and Schlecthendal, 
"who do not mention the color, and whose description of the species applies better to what we 
take for a state of R. macropetalus than to this plant. 
RUBUS MACROPETALUS, Dougl. in Hook. Fl. Bor.—Amer. 1, p. 118, t. 59; Torr. & Gray, l. c. 
Cocomungo, California; March 18. The main stems are often prostrate, throwing up short 
erect branches. The leaves are mostly trifoliolate, except the uppermost ones, which are some- 
times simple and 3-lobed. All the specimens seem to have perfect flowers. 
RuBUs TRIVIALIS, Michx. Fl. 1, p. 296. Low places near Mark West's creek, California ` April 
30. Petals elliptical-lanceolate, nearly twice the length of the sepals. Leaves all trifoliolate ; 
leaflets rhombic-oblong. Perhaps only a state of R. macropetalus. 
Rosa FOLIOLOSA, Nutt. in Torr. & Gray, Fl. 1, p. 460. Upper Canadian river, and in the 
Sandia mountains ` September—October. In fruit. 
Rosa GYMNOCARPA, Nutt. in Torr. € Gray, Fl. 1, p. 461. Near Bolinas, April 19; wet ravines, 
Grass valley, May 20, (in flower) ; also mountains near Oakland ; April 5, (with the fruit of the 
preceding season). A very neat slender species. The leaflets vary from less than half an inch 
to three-fourths of an inch long. The flowers are scarcely an inch in diameter. 
Rosa BLANDA, Ait. Kew. (ed. 1,) p. 202; Torr. € Gray, Fl. 1, p. 459. R. fraxinifolia, Bork. ; 
Torr. & Gray, l.c. R. Californica, Cham. & Schlecht. in Linnea, 2, p. 35. R. Woodsii, 
` Lindl.; Torr. & Gray, l1. c. Knight's ferry, Stanislaus river, May 7; Grass valley, May 19; 
low places, Mark West's creek, California ; April 30 (with fruit of the preceding season.) This 
is a variable species, including, as we think, all those quoted above. 
PYRUS RIVULARIS, Dougl. in Hook. Fl. Bor.—Amer. 1. p. 203, t. 68; Torr. € Gray, Fl. 1, p. 
71; Nutt. Sylv. 2. p. 22. t. 49. Santa Rosa creek, California; May 1.

Fi. 1, p. 413 ; Cajon Pass, March 16, (with unexpanded flowers.) Martinez, April 23, (young 
fruit ;) Mark West's creek, California; and April 30 (mature fruit). 
AMELANOHIER CANADENSIS, var. ALNIFOLIA, Torr. & Gray, FT. 1, p. 473. Near Punta de los 
Reys, April 17. Hill sides, Nevada, May 20. Hills near Williams” fork of the Great Colorado. 
Another form of this species was found on the middle Yuba. It has ovate or obovate leaves, 
which are often nearly entire, or with only a few serratures at the summit. The racemes are 
6-S-flowered, and the peduncles as well as the segments of the calyx are woolly.
