16. PODOSCIADIUM, Gray. 



Calyx -teeth small, searious, subulate. Stylopodium short, conical. Fruit linear- 

 oblong, laterally compressed, with a rather broad commissure, somewhat contracted 

 at the apex ; ribs narrow and filiform ; oil-tubes 1 or 2 in the intervals,- 4 on the 

 commissure. Seed reniform in section, slightly channelled on the back under the 

 oil-tubes, broadly furrowed on the face, with a central longitudinal ridge. Car- 

 pophore 2-partcd. ■ — Smooth branching Californian perennials ; leaves pinnately or 

 somewhat ternately decompound, with linear leaflets ; umbels long-peduncled, with 

 involucres and Lnvolucels of several lanceolate acuminate subscarious bracts; flowers 

 white, polygamous. 



1. P. Calif brnicum, Gray. Stem 3 or 4 feet high: segments of the leaves 

 linear, entire or toothed, the terminal one elongated, an inch or two long ; upper- 

 most leaves simple : umbels 9 - 12-rayed, the primary umbel fertile, with rays two 

 inches long; the others sterile, with rays an inch long and very slender pedicels 

 exceeding the bracts : petals shortly acuminate : fruit 4 lines long, shorter than the 

 pedicels, li lines broad, with obtuse ribs: oil-tubes and seeds as described in the 

 generic character. — Proc. Am. Acad. vii. 346. Ckaerophyllum (?) Californicum,

Collected only by Bigclow at Knight's Ferry ; May. 



2. P. Bolanderi, Gray. Two feet high : leaflets pinnate, the segments more 

 narrowly linear : umbels many-rayed ; rays 5 to 9 lines long ; the conspicuous 

 searious involucels exceeding the pedicels : petals very long-acuminate, with the 

 midvein strongly impressed : fruit 1 J lines long, oblong, the narrow ribs becoming 

 elevated and undulate; oil-tubes more numerous and obscure, 2 or 3 in the inter- 

 vals : seed more compressed dorsally, and broader in proportion, not grooved on the 

 back, tin' facial sulcus broad and shallow and but slightly raised in the centre.- —

A closely allied plan!, 1ml differing from any of the preceding genera, has been collected in 

 the Vosemite Valley by both Dr. Torrey and l>r. Gray, with the fruit however too immature for 

 its satisfactory determination. The fruit us found is narrowly oblong, I lines long, laterally coni- 



Sresscd with a rather wide commissure, slightly ribbed on the' hack ; disk evident, but stylopodium 

 epressed ; oil-tubes obscure, probably solitary in the intervals ; seed subterete, with a deep tri- 

 angular facial sulcus; carpophore -2-parti-d. The plant is a foot high or less, glabrous, slender, 

 shortly caulescent; leaves ternate or bipinnate, with linear acute segments, 1 to :i lines lo 

 umbels few-rayed, the rays very unequal, an inch long or less ; involucre none ; involucels of 1 

 or 2 small bractlets ; flowers yellow, the calyx-teeth obsolete. 



17. (ENANTHE, Linn. 



Calyx-teeth rather prominent, acute. Stylopodium short-conical, the styles at 

 length elongated. Fruit oblong to globose, not compressed, with a broad commis- 

 sure, the ribs rounded and corky, with very narrow intervals; oil-tubes solitary. 

 Seed somowhat compressed dorsally, flat on the face. Carpophore none. — Gla- 

 brous herbs, mostly aipiatie ; leaves pinnate or decompound; umbels usually in 

 volucrate ; Sowers white.
