Daucus pusillus, Michx. FI. 1, p. 164; Torr. & Gray, FI. 1, p. 636. Hill-sides, Napa, 
April 25. This plant has some reputation among the Mexicans as a remedy for the bite ot 
venemous serpents; but its efficacy is very doubtful. 
Daucus brachiatus, Sieh.; DC. Prodr. 4, p. 514; Gray, Pot. TJ. S. Expl. Exped. 1, p. 711. 
Scandix glochidiata, Labill. PI. N. Holt. 1, p. 75, t. 102. Caucalis microcarpa, Hook. & Am. 
Pot. Beech, p. 348; Torr. & Gray, FI. 1, p. 636. Hill-sides, Knight’s ferry, Stanislaus, May 1, 
(in fruit.) A widely diffused plant, being found in Australia, New Zealand, Peru, Chili, many 
parts of Mexico, and California. It may have been brought to California by cattle. An 
original specimen of Labillardiere differs from our plant only in the rather denser prickles ot 
the fruit. It is more nearly related to Caucalis than to Daucus, but does not accord wholly 
with either genus. 
Cilerophyllum ? Californicum (sp. nov.) : perenne, erectum, elatum, glaberrimum; foliis 
triternatisectis, lobis linearibus integris vel paucidentatis; involucro polyphyllo; calycis mar- 
gine 5-dentato; fructibus oblongis utrinque obtusis, costis vix elevatis. Wet ravines, Knight’s 
ferry, Stanislaus, May 8; in flower and fruit. Stem 3-4 feet high, nearly simple. Leaves 
(including the petioles) a foot in length; the primary divisions biternately or bipinnately 
divided; the segments either all (except the elongated terminal one) coarsely 2-3-toothed, or 
nearly entire and linear; uppermost leaves simply 3-parted with entire divisions. Umbels on 
very long peduncles, the primary one wholly female, 9-12-rayed. Involucre 9-12-leaved, 
scarcely one-fifth the length of the rays. Lateral umbels wholly male. Umbellets many- 
flowered, about an inch long. Involucels of numerous entire lanceolate leaves. Petals white, 
broadly oval, emarginate, with a small indexed point. Calyx with 5 distinct acute teeth. 
Stylopodium broadly conical. Styles half the length of the ovary, recurved. Fruit about five 
lines long, often a little curved, or gibbous, laterally compressed: roericarps obscurely ribbed, 
with large single vittje in the intervals and 4 in the commissure. Seed deeply furrowed on the 
face, but not involute, with an elevated central ridge; carpophore 2-cleft at the summit. We 
are by no means satisfied with our disposition of this plant. It rather falls into this genus than 
into any other known to us; yet it differs much in habit and in several characters from Cluero- 
phyllum. 
Osmorhiza BRACHYPODA, Torr . in Durand’s Plantce Pratt. {Jour. Acad. Phil. n. ser. 2, p. 79). 
Hill-sides, Yuba, Downieville, California; May 22. It was also found with mature fruit by Dr. 
Parry near Monterey, and by Mr. Pratt.en on Deer creek. The flowering specimens collected 
by Dr. Bigelow are only a foot high. Easily distinguished from 0. brevistylis and 0. longi- 
stylis by the very short pedicels of the fertile flowers and fruit, the minute stylopodium, and 
shorter trapezoidal segments of the leaves. In the short styles it is nearest 0. brevistylis, but 
it is quite glabrous, and the fruit is much more hispid on the angles than in that species. 
Osmoriuza nuda (n. sp.): stylis brevissimis; fructibus obtusis; involucris et involucellis 
nullis; pedicellis fructu longioribus. Shady woods, Napa valley, April 27. Plant about two 
feet high. Leaves on long petioles, which, as well as the lower part of the stem, are strigosely 
pubescent; segments broadly ovate, often deeply 3-lobed, coarsely dentate-serrate. Peduncles 
enlongated. Umbel about 4-rayed; umbellets 4-6-flowered. Flowers like those of 0. brevis¬ 
tylis. Fruit (immature) very hispid, especially towards the base, crowned with a short conical 
stylopodium. This species is intermediate between Osmorhiza and Glycosma. In its bristly 
fruit it is like the former, and in the short stylopodium and styles, as well as in the entire 
absence of the involucres, it resembles tbe latter. The two genera should, perhaps, be united. 
Cynapium apiifolium, Nutt, in Torr. dc Gray, FI. 1, p. 640. Tarnul Pass, April 11; in flower. 
This plant had not been found before in California. 
Subgenus? MiCROTiENiA. Calycis margo obsoletus. Petala ovata, cum lacinula elongata in- 
flexa. Stylopodium minutum, depressutn. Styli elongati, recurvi. Fructus ovalis, a latere 
contractus. Mericarpia jugis obtusissimis ; valleculis 3-5-vittatis. Commissura 6-8-vittata,
