BOTANY. 
label of this plant got misplaced, but we suppose tbe specimens were collected near the coast. 
They agree with others found near San Luis Rey, California, by Dr. Parry. 
Berula angustifolta, Koch ; Gray, PI. Fendl. p. 55, and PI. Wright. 2, p. 65. In water, 
near San Domingo, New Mexico ; October. In fruit. 
Cymopterus montanus, Nutt, in Torr. & Gray, FI. 1, p. 624; Gray, PL Fendi., p. 56. 
William’s river, New Mexico ; January 26, (scarcely in full flower.) Called by tbe Mexicans 
Gamote or Camote. Tbe root is about as thick as a man’s thumb, and seems to be farinaceous. 
Peucedanum leiocarpum, Nutt, in Torr. tb Gray, FI. 1 , p. 626. Seseli leiocarpum, Hook. FI. 
Bor.-Amer. 1 , p. 262, t. 93. Hill-sides, Napa, California, April 25 ; in flower. The segments 
of the leaves are broader than in the Oregon plant; so that we suspect P. latifolium may be 
only a variety of this species. 
Peucedanum nudicaule, Nutt, in Torr. & Gray, FI. 1. c. Ferula Nuttallii, DC. Prodr. 4, p. 
173. /?? ellipticum, Torr. & Gray, in BecJcivith’s Pep. Hill-sides, Sonoma, May 3 ; (with 
flowers and immature fruit), and Feather river, near Marysville, California; with mature fruit. 
Tbe fruit is so much longer and narrower in proportion than in the normal form of P. nudi- 
cuale that we would have described this plant as a distinct species, were there other marks 
of difference ; which, however, we have not been able to find. Besides, in other species of this 
genus there is considerable variation in the form and size of the fruit. 
Peucedanum tomentosum, Bentli. PI. Hartw., p. 312. Knight’s Ferry, Stanislaus river, 
May 7 ; with immature fruit; and Corte Madera, California, on hills. We have a strong 
suspicion that this species, P. dasycarpon, macrocarpon, and foeniculaceum (at least the western 
plant) are not distinct. We have many intermediate forms that appear to connect them ; but 
are unwilling, at present, to unite them. 
Peucedanum dasycarpum, Torr. & Gray, FI. 1, p. 628. Knight’s Ferry, Stanislaus river, 
May 7 ; with immature fruit. Peduncles 15 inches long. Ultimate segments of the leaves 
narrowly linear. Fruit (not mature) elliptical-obovate, very woolly. Segments of the invo- 
lucels lanceolate Perhaps not sufficiently distinct from P. foeniculaceum. The number of 
North American species of this genus will doubtless be reduced when they are carefully studied 
with more ample materials than we now possess. 
Peucedanum caruifolium, Torr. <b Gray, FI. 1. c. Ferula caruifolia, Hook. & Am. Bot. 
Beech, p. 348. Mark West’s creek, Napa valley, and on hill-sides, near Sonoma, California, 
April—May. The specimens are much larger than the original ones of Douglas and Nuttall, 
being about a foot and a half high. This is pretty certainly P. marginatum, Benth. PI. Hartio. 
p. 312, No. 1752 ; and we suspect that it is also P. abrotantifolium, Nutt. PI. Gambel. 
Peucedanum utriculatum, Nutt, in Torr. & Gray, l. c. Hill-sides, Martinez; mountains 
near Oakland ; Mark West’s creek, and Cocomungo, California ; March—April. 
Leptot2ENIA ? Californica, Nutt, in Torr. of Gray, FI. 1, p. 630. Hills, near Tokeloma 
creek, April 17, (with flowers and young fruit;) Napa valley, April 26, (with nearly ripe fruit.) 
This plant, which Nuttall referred with doubt to Leptotienia, and thought (as he had not seen 
the fruit) might perhaps be a species of Poly taenia, does not accord entirely with either genus. 
From the former it differs in having emarginate petals with a long indexed point, and 6 vittte 
on the commissure, with numerous true vittae on the back, and nearly obsolete ribs ; the involu- 
cels also are wanting. From the latter it disagrees in the toothless calyx, as well as in wanting 
the involucels. The fruit is oval or elliptical, about 5 lines long, and the border is rather thin. 
Many of the flowers are abortive, and in some of the umbels all are so. The primary rays are 
about 3 inches long. 
Heracleum lanatum, DC. Prodr. 4. p. 192. Torr. <b Gray, FI. 1, p. 632. H. Douglasii, 
DC. 1. c. Corte Madera, California, April 10; in flower. Scarcely more pubescent than the 
eastern plant,
