 thick and corky. 



Leaflets linear or nar- 

 rowly lanceolate. 361. SiuM, 267.

338. ERYNGIUM. 



Glabrous perennials; leaves often rigid, coriaceous, entire, 

 spinosely toothed or divided; flowers white or blue, sessile, in 

 dense bracteate heads; sepals very prominent, rigid and persistent; 

 stylopodium wanting; styles short or long, often rigid; fruit ovoid, 

 compressed laterally, covered with hyaline scales or tubercles; 

 carpel with ribs obsolete; oil-tubes mostly 5, 3 dorsal and 2 

 commissural; seed face plane. 



Eryngium petiolatum Hook. Stems erect, 30-40 cm. high; lower leaves 

 reduced to long nodose petioles, sometimes with small lanceolate remotely 

 spinulose blades; upper leaves opposite, narrow, spinulose-serrate; heads 

 globose, about 8 mm. wide; bracts and bractlets subulate, ciliate-spinulose, 

 twice as long as the heads. 



In swales, rare, western Oregon. First collected by Douglas. 



339. SANICULA. S.\NirLE. 



Perennial tall rather glabrous herbs, with ternate or palmate 

 leaves; flowers perfect and staminate mixed in heads in few-rayed 

 umbels, yellow or green; involucral bracts few; calyx-teeth 

 evident, persistent; fruit globular, the carpels not separating, 

 ribless, the whole surface covered with hooked bristles. 



Fruit 6-7 mm. long; styles much exceeding the bristles. 5. marilandica. 

 Fruit 4 mm. long or less; styles not exceeding the bristles. ' 



Mature fruit stipitate; leaves palmately divided. 5. menziesu. 



Mature fruit sessile, not stipitate. 



Leaves pinnately parted, the segments incised. S. hipinnatifida. 



Leaves palmately divided. 



Principal leaf divisions confluent at base. S. hoivellii. 



Principal leaf divisions distinct at base. 5. septcntrionalis. 



Sanicula marilandica L. Stems erect, 30-120 cm. high; leaves 5-7-parted, 

 the divisions incisely serrate and cleft; umbels 3-7-rayed; sterile flowers numer- 

 ous, sometimes in separate umbellets; fruit sessile, 6-7 mm. long, its bristles 

 bulbous-based. 



Vancouver Island, British Columbia, Macoun, and eastward. 



Sanicula menziesii Hook. & Arn. Stems erect, 30-100 cm. high, branched 

 above; leaves mostly basal, cordate-orbicular, palmately v^-5-lobed, 5-10 cm. 

 broad, the lobes incisely cleft and toothed, the teeth bristle-tipped; umbel 

 3- or 4-rayed; involucral bracts leaf-like; involucels 6-8, linear, entire; flowers 

 yellow; fruit sessile, stipitate, obovate, 2-4 mm. long, very bristly. 



Common especially on bluffs along the seashore. The northern plant is 

 feebly distinguishable from the typical plant of California by having the leaf- 

 lobes obtuse or obtusish instead of acute. It has been named 5'. tripartita 

 Suksdorf.
