3. E. armatum C. & R. Coast Eryngo. Stem diffusely branching, 3 to 5 or 

 10 inches long; leaves broadly oblanceolate, incised or merely serrate, the teeth 

 spinose ; bracts and bractlets very prominent, broadly lanceolate, strongly spinose- 

 tipped, with a callous margin, entire or with a pair of spinulose teeth below, some- 

 times scarious-winged at the very base, 3 to 7 lines long ; sepals usually exceeding 

 the styles. 



Dry adobe flats and hills and summits of sea bluffs along the coast, 10 to 90 

 feet : San Luis Obispo Co. to Humboldt Co. ; low valleys bordering San Francisco 

 Bay. June-July. 



Geog. note. — Like some other species of the genus the ecological limits of Eryngium armatum 

 are narrow. While most characteristic of the low hUls and flats facing the sea, where it is often 

 the dominant on grass lands, it also grows on the flats of low valleys bordering San Francisco Bay. 

 It is never found in the interior. Eryngium ptnnatisectum of the Sierra Nevada foothills simu- 

 lates it only as to the bracts. Extremely abundant on the Point Reyes peninsula, Eryngium arma- 

 tum is regarded by the cattlemen as an objectionable weed. The earliest leaves are usually 

 pinnately divided with broad (l^/^ to 2 lines wide) rachis and remote narrow few-toothed or entire 

 segments. About Point Joe on the Monterey coast the heads are very small; northward, espe- 

 cially on the Sonoma and Mendocino coasts, the heads become larger with a corresponding in- 

 crease in size of the bracts. Sometimes, as on the Sonoma coast, the heads are bluish.
