62 BOTANY. 
Geronimo Ranch; April 12. Differs from the ordinary form of A. nemorosa, in its tall stem 
(which is a foot or more below the involucre), the elongated petioles, and the pretty strong 
pubescence of the leaves. The leaflets are rhombic-ovate, incised and rather coarsely toothed, 
but the lateral ones are not two-parted in any of the specimens. Such leaflets, however, occur 
now and then in the eastern A. nemorosa. Rev. Mr. Spalding found the same plant on the 
Kooskooskee, in Oregon, and it exists in Geyer's collection. 
RANUNCULUS AQUATILIS, Linn. sp. p. 556. Corte Madera; in water ; P». 10-13. This seems 
not to be the form or species which almost universally fecken the section Batrachium in 
North America, but what is called R. aquatilis by those European authors, who do not subdivide 
the Linnean species extremely. It is a state destitute of emersed leaves. 
RANUNCULUS HEDERACEUS, Linn. var. With the preceding. Nearly the R. tripartitus, D.C., 
as to the leaves, etc. ; but the receptacle of the fruit is glabrous. The petals are oblong-obovate 
and twice the length of the calyx. This is the first Batrachium, bearing emersed leaves, which 
we have received from any part of North America. - 
RANUNCULUS TRACHYSPERMUS, var.? LINDHEIMERI, 0 in Pl. Lindh. 1, p. 3. Napa valley, 
in wet places; April 26. The granulate roughened carpels principally distinguish this from R. 
pusillus (to which R. oblongifolius, EU., with large bright yellow petals, numerous stamens, and 
apiculate achenia, does nof: properly belong). The heads of carpels incline to become oblong. 
RANUNCULUS DIVARICATUS, Schrank; Gray, Pl. Wright. 2, p. 8. Inthe bed of the Pecos ; October. 
RANUNCULUS AFFINIS, FR. Br. ; Var. B. Hook. Fl. Bor.-Am. 1, p. 13, t. 6. Near San Antonita ; : 
October. In fruit. 
RANUNCULUS CALIFORNICUS, Benth. Pl. Hartw. p. 295. R. dissectus, Hook. & Arn. Bot. Beech. 
p. 316. R. delphinifolius, Torr. € Gray, Fl. Suppl. p. 659, non H. B. € K. Los Angeles; 
March 21. This is R. acris ñ. Torr. € Gray = R. Depp, Nutt. Mss. It agrees exactly with 
Nuttall's specimens. Two forms of the plant were collected by Dr. Bigelow. 1. About a span 
high, manifestly pubescent, and the leaves with narrowly linear segments. 2. Tall and stout ; 
less pubescent; leaves with oblong-cuneate segments. Fremont gathered the latter in 1846, 
near San José. 
RANUNCULUS REPENS, Linn.; Torr. de Gray, Fl. l.c. San Francisco; April 5. Resembles the 
European. In the long styles it agrees with some of the forms of this polymorphous species, 
though not with the ordinary state of it, that we find in the northern States. 
RANUNCULUS canus, Benth. Pl. Hartw. p. 295. Hill sides, Duffield’s Ranch, Sierra Nevada و‎ 
May 11. A less white-hairy form ; some of the radical leaves only 3—5-parted. The plant is 
probably only a state of R. repens. 
RANUNCULUS HEBECARPUS, Hook. & Arn. Bot. Beechey, p. 369. R. parviflorus, Torr. & Gray, 
Fl. 1,p*25. Along rivulets, Sonora, May 9th; and hill-sides, Knight's Ferry, Stanislaus ; 
May 8. Not an uncommon species in the southern part of California. It is regarded by most of 
our botanists as a variety of R. parviflorus, which, indeed, it very much resembles. This species 
differs, however, it being much less hairy ; the lobes of the leaves are broader and less acute ; 
the fruit is decidedly tuberculate, while in R. hebecarpus it is merely a little roughened, and the 
pubescence longer. In the latter the beak of the fruit is decidedly shorter than in the former. 
AQUILEGIA CANADENSIS, Linn. ; Torr. & Gray, Fl. 1, p. 29; var. sepalis limbo petalorum 
duplo-longiorius, calcare subequalibus. A formosa, Fisch. in DC. Prodr. 1, p. 20; Torr. & 
Gray,l. c. Plains near Oakland, California; April 5. 
DELPHINIUM NUDICAULE, Torr. £ Gray, Pl. 1 y p. 39; d 661. D. sarcophyllum, Hook. & Arn. 
Bot. Beechey, p. 317. Hill sides, Napa valley, April 27, and near San Geronimo Ranch, Cali- 
fornia, April 12. A beautiful species with large scarlet flowers. It would be a great acquisi- 
tion to our gardens. 
A splendid scarlet-flowered Delphinium was discovered by Dr. Parry, in 1850, on the mount- 
ains east of San Diego. It is D. coccinium, Torr. (Bot. Mexican Boundary Survey, with a
