Barren hills on the Oregon, Nuttall! Dr. Scouler! Douglas. California,
Douglas.—Stem 1-3 inches, and the peduncle 8-12 inches long. “ Flowers
white,” Nutt. Fruit nearly three-fourths of an inch in length, with a
thin pale border.—Differs from P. fceniculaceum chiefly in , the fruit, which
is much larger and proportionally narrower, and the wings nearly twice as
broad. We have described this plant from specimens collected by Mr. Nut-
tall. It may not be identical with Ferula macrocarpa, Hook. Am.

vate-oblong; fruit nearly orbicular, tomentose-pubescent, about the length of
the pedicel; vittse single in the dorsal intervals, 2 in the lateral ones ; commissure
with 4 vittse.
California, Douglas!—Leaves 2-3 inches longf the lamina about the
length of the petiole, the ultimate segments 1-2 lines long, rather crowded.
Peduncle of the fructiferous umbel 6-8 inches long; stout. Rays 4-5 principal,
and several shorter abortive ones. Involucel (colored?) strongly veined.
Fruit one-third of an inch in diameter, when young broadly ovate, but in the
mature state nearly as broad as long: the vittffi not perceptible, externally.
A. very distinct species, which is not described in Hooker 6c Arnott’s account
of Douglas’s Californian collection. Our specimens were received from the
London Horticultural Society, through the kindness of Mr. Bentham.
10. P. parvifolium: somewhat caulescent, glabrous; lamina of the radical
leaves as long as the petiole; the circumscription deltoid, tripinnatifid; the

subulate leaflets ; fruit elliptical-obovate, the wing as broad as the disk ;
ribs slightly prominent; intervals with single vittte ; commissure with 4
vittse.—Ferula parvifolia, Hook. Am, i let. Beechey, suppl. p. 348,
California, Douglas /—Plant about a foot high When in fruit. Stems very
short, several from a single root. Lamina of the leaf about 14 inch long :
segments incised, with short acute lobes. Flowers bright yellow. Fruit
One-third of an inch long; the ribs nearly obsolete.'
11. P . caruifolium: minutely pubescent, stemless or nearly so; leaves
ternately decompound, with long narrowly linear acute segments; petioles
very short, with a large very broad inflated base; involucel 9-12-leaved ; the
leaflets distinct, broadly obovate, petiolulate; fruit broadly elliptical, with
scarcely prominent ribs ; the wing about half the breadth of the disk ; vitt®
very indistinct, apparently 1-2 in the dorsal intervals and 2-3 in the lateral
ones. Ferula caruifolia, Hook, /y A m .! lot. Beechey, suppl. p. 348. Peucedanum

California (plains of St. Barbara, Nuttall!), Douglas /—About a span high.
Ultimate segments of the leaves nearly half an inch in length and' half a line
wide. Flowers bright yellow. Fruit one-third of an inch long. Vittte minute
and empty in Douglas’s specimens, so that the fruit is nearly tasteless.
P. utriculatum (Nutt.! mss.): glabrous, branching from the base;
leaves ternately decompound ; ultimate segments narrowly linear, loose ; in-
volucels about 7-leaved ; the leaflets distihct nearly to the base, broadly-obo-
vate, petiolulate, nearly as long as the umbellet; fruit obovate-elliptical,
with a broad winged margin ; intervals with single vittte ; commissure with
4-6 vittaj.
Rocky plains, particularly near thé confluence of the Wahlamet and Oregon
Rivers, Nuttall! Mr. Tolmie /—Root tuberous. Stem from a few inches
to a foot or more in length, decumbent’. Petiole ternately divided down to
the dilated base. Peduncles terminal and opposite the leaves. Umbel of
from 12 to 20 very unequal rays. Leaflets of the involucel often toothed at the
summit. Flowers bright yellow. Petals obcordate, with an inflexed point.
Frjiit about one-fourth of an inch long, about the length of the pedicel: dorsal
ribs prominent. Intervals filled with broad thin vilt®.—The root is used as
food by the aborigines. Nuttall.

Qarpels with 5 obtuse slightly, prominent approximated equidistant
ribs. Intervals with single large vittaé. Commissure with 2 vittse. Seed
flat, somewhat concave on the back.—A perennial glabrous herb. Leaves
ternately divided ; the segments broadly cordate, somewhat lobed, coarsely

length, glabrous and somewhat shining.
