264 UMBELLIFERiE. CEnanthe. 



1. CB. Californica, Watson. Biennial or perennial ; stems succulent, usually 

 weak, 2 to 5 feet high : leaves ternate and bipinuate, the pinna3 nearly sessile ; 

 leaflets approximate, ovate, acute or acutish, tootiied, often lobed at base, a half to 

 an inch long : umbels many-rayed, with one or two linear involucral bracts or 

 naked ; rays an inch long or less ; pedicels numerous, short : fruit crowded, nearly 

 1 1 lines long, oblong, obtuse at each end, tipped with the long spreading styles ; 

 ribs and commissure very corky : seed somewhat dorsally compressed, usually 

 angled ; oil-tubes at the angles. — Proc. Am. Acad. xi. 1 39. 



In marshes at Point Lobos, and southward to San Diego County. 



2. (B. sarmentosa, Nutt. Very similar : leaves usually broader and more 

 open; leatiets acuminate, mostly smaller. — Ton. & Gray, Fl. i. 617. Phellan- 

 drlum aquaticuvi, Pursh. 



Washington Territory and Oregon ; Fkimas Co., Lanmon. Tlie succulent stems have the taste 

 of Celery and are eaten by the Indians. 



18. LIGUSTICUM, Linn. 

 Calyx-teeth obsolete. Stylopodium usually conical ; margin of the disk undu- 

 late. Fruit ovate or oblong, with a broad commissure, somewhat dorsally com- 

 pressed ; ribs somewhat prominent and acute or narrowly winged, the lateral ones 

 usually broadest; oil-tubes obscure. Seed dorsally flattened, somewhat concave on 

 the face. Carpophore 2-parted. — Smooth perennials, usually tall; leaves pinnately 

 or ternate and pinnately decompound ; undjels many-rayed, naked or iuvolucrate ; 

 flowers white. 



A genus of about 20 or 25 species, of the northern hemisphere, chiefly of the Old World and 

 most of them rather obscurely characterized. 



1. L. apiifolium, Benth. & Hook. Eather stout, 2 to 4 feet high, branching 

 above : leaves ternate or biternate, the divisions pinnate or bipinnate ; segments 

 ovate, I to 1| inches long, laciniately pinnatifld, the lobes acute or acuminate : um- 

 bels long-peduncled, without involucre or rarely with 1 or 2 slender bracts, the rays 

 1 or 2 inches long, scabrous-jiuberulent above; involucels of several narrowly linear 

 entire bractlets ; pedicels slender, 2 or 3 lines long : fruit oval, 2 lines long, with a 

 conical stylophore ; carpels somewhat quadrangular ; ribs narrow, acute ; oil-tubes 

 3 to 5 in the intervals, 4 to 8 on the commissure : seed reniform in section, with 

 a medial longitudinal ridge. — Gen. i. 912. Cyncqyium apii/oiiimi, Nutt. in Torr. 

 & Gray, Fl. i. 641. 



In the mountains from the Columbia Kiver southward ; Yosemite Yalley (Bolander) ; Big Tree 

 roail and Ebbett's Tass (Brewer) ; Conner Lake, Torrcy. The Californian plant agrees with that 

 of Oregon in all its characters. Specimens collected at Tamalpais by Bigclow were referred here 

 by Dr. Torrey, probably correctly, but they were only in flower. What appears to be the same 

 is also found in Colorado, but the segments of the leaves are smaller, the involucels wanting, 

 and the fruit (immatm-e) somewhat larger. 



A doubtful form, var. minok, Gray in herb., is found at Ostrander's Meadows {Bolander), and 

 Ebbett's Pass (2?rcM-er) ; stem 9 to 15 inches high, with 1 or 2 umbels ; leaves all nearly radical, 

 temate-pinnate ; the still immature fruit 2^ lines long, rather strongly ribbed, the seed more 

 depressed and without the central ridge. 



L. scoPULORUM, Gray, the more prevalent species in the Rocky Mountains, may perhaps be 

 found in the northern Sierra Nevada, distinguished by the more depressed-reniform seed and 

 by the oval more broadly winged fruit. 



19. SELINUM, Linn. 

 Characters of Ligiisticum, but the fruit rather more prominently winged, the oil- 

 tubes solitary and conspicuous in the intervals, and the seed nearly flat on the face. 

 — Tall stout branching perennials, Avitli i)innately decompound leaves.
