Angelica. UMBELLIFERiE. 265 



A genus of about 25 species (according to Benth. & Hook.), almost exclusively of the northern 

 hemisphere ; perhaps half a dozen in North America. 



* Involucels conspicuous: pedicels slender: fruit smooth, with thin wings. 



1. S. Pacificum, Watson. Leaves ternate-bipinnate, the ovate acutish seg- 

 ments an inch long, laciniately toothed and lobed : umbels on stout peduncles, 

 about 15-rayed, with an involucre of 2 or 3 lobed and toothed leallets, an inch 

 long, equalling the rays ; involucels of several narrowly linear entire or 3-toothed 

 bracts equalling the floAvers ; pedicels 2 or 4 lines long : fruit oljlong, 3 or 4 lines 

 long, 1 \ lines broad ; stylopodium slightly prominent above the disk ; the wings 

 rather narrow ; oil-tubes conspicuous, very rarely in pairs : seed channelled under 

 the dorsal oil-tubes. — Proc. Am. Acad. xi. 140. 



Saucelito Hills, near San Francisco, Kellogg & Earford. 



* * Umhels nalced ; pedicels very short or none, the floivers and hirsute fruit crowded 

 or in globose heads : ivings corhj. 



2. S. capitellatum, Benth. & Hook. Very stout, 2 to 5 feet high, smooth : 

 leaves large, with mucli dilated petioles, bipinnate, the few leaflets oblong- to linear- 

 lanceolate, an inch or two long, coarsely laciniately toothed or lobed : umbels 2 or 3, 

 tomentose, 6 - 8-rayed ; nmbellets globose, 3 to 6 lines in diameter, the pubescent 

 flowers sessile on a dilated receptacle : disk prominent, the stylopodium depressed : 

 fruit cuneate-obovate, 3 lines long, strongly ribbed, the lateral wings broader than 

 the 3 upright dorsal ones : seed reniform, with shallow grooves for the dorsal oil- 

 tubes.— Gen. i. 915 ; Watson, Bot. King Exp. 12G. Sphcenosciadiam capitellatum. 

 Gray, Proc. Am. Acad. vi. 536. 



Stream-banks in the Sierra Nevada, fi'om Mono to Doniier Tass, especially on the eastern^ slope. 

 Another closely allied species is found in the mountains of Northern Nevada, S. Kingii, ^^ atson, 

 1. c, with less tomentose inflorescence, the fruit oblong-oval, on pedicels a line or two long. 



20. ANGELICA, Linn. 



Calyx-teeth obsolete or minute. Stylopodium depressed. Fruit ovate, strongly 

 flattened dorsally with a very broad commissure, margined by the broad membra- 

 nous distinct lateral wing ; dorsal ribs prominent but narrower ; oil-tubes solitary 

 in the intervals, or the lateral in pairs. Seed flattened, the face flat or slightly con- 

 cave. Carpophore 2-parted. — Usually tall and stout perennials ; leaves pinnate or 

 compound, the toothed segments usually broad and the petioles much dilated ; um- 

 bels many-rayed, naked or nearly so ; flowers Avhite or purple. 



About 30 species in the north temperate and Arctic zones ; ten or more North American. 



1. A. Breweri, Gray. Glabrous or somewhat puberulent, 3 or 4 feet high : 

 leaves ternate or quinate and pinnate ; leaflets lanceolate or oblong-lanceolate, acu- 

 minate, 2 or 3 inches long, sharply serrate with cuspidate teeth, the lower some- 

 times lobed at base: peduncles long, often witli 1 or 2 entire ddated somewliat 

 membranous bracts: umbels naked; rays 2 inches long: fruit pubescent oblong, 

 4 lines long and 2 broad, the lateral wings narrow and corky, as thick as tlie seed, 

 the dorsal obtuse and little prominent ; oil-tubes usually 6, besides 2 to 4 on tlic 

 commissure, the lateral or dorsal in pairs : seed more or less concave on the iace, 

 with sometimes a longitudinal medial ridge, the oil-tubes sunk m deep depressions 

 on the back. —Proc' Am. Acad. vii. 348 ; Watson, Bot. King Exp. 126. 



In the Sierra Nevada from Tlumas Co. {Mrs. Ames) to Ebbetfs Pass and the Big Tree road 

 (Bolandcr, Torraj, Brdccr) ; N. W. Nevada, Watson.
