Angelica. TJMBELLIFERJS. 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. Facificum, 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 leaflets, an inch 

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

 bracts equalling the flowers ; pedicels 2 or 4 lines long : fruit oblong, 3 or 4 lines 

 long, 1| lines broad; stylopodiuru 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. 



Saueelito Hills, near San Francisco, Kellogg & Harford. 



* * Umbels naked ; pedicels very short or none, the flowers and hirsute fruit crowded 

 or in globose heads : wings corky. 



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

 leaves large, with much 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 ; umbellets 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 Avings broader than 

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

 tubes. Gen. i. 915; Watson, Bot. King Exp. 126. Sphcenosciadium capitellatum, 

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



Stream-banks in the Sierra Nevada, from Mono to Donner Pass, especially on the eastern slope. 

 Another closely allied species is found in the mountains of Northern Nevada, S. KINGII, Watson, 

 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 white 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 termite 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 with 1 or 2 entire dilated somewhat 

 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 the seed, 

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

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

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

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



In the Sierra Nevada from Plumas Co. (Mrs. Ames) to Ebbett's Pass and the Big Tree road 

 (Bolander, Torrey, Brewer) ; N. W. Nevada, Watson. 



2. A. tomentosa, Watson. Very stout, hoary-tomentose throughout or the 

 stem glabrous : leaves quinately bipinnate, the leaflets thick, ovate, acute, very
