SOW THISTLE 



Sonchus arvcnsis. Composite Family 



Perennial by deep roots and creeping rootstocks. Stems: leafy below, 

 panicnlately branched and nearly naked above. Leaves: lower and basal 

 runcinate-pinnatifid, spinulose-dentate. Flowers: heads several, corym- 

 bose-paniculate, bright yellow, very showy. Fruit: achenes oblong, com- 

 pressed, with about ten rugose longitudinal ribs. Not indigenous. 



Every traveller will easily recognize this common Sow 

 Thistle, with its yellow or yellowish flowers and its very 

 prickly leaves. Sometimes it is called Milk Thistle, on ac- 

 count of the milky juices contained in the stems. Like 

 many of the members of the great family of Composites, 

 the Sow Thistle has an involucre of green bracts, a flat 

 naked receptacle, and numerous strap-shaped rays, which 

 are truncate and finely toothed. It is a coarse showy weed, 

 and opens its flowers early in the day, closing them again 

 soon after noon. This is an introduced plant. 



LARGE-FLOWERED FALSE DANDELION 



Agoseris glauca. Composite Family 



Stems: scape naked, slender, pubescent. Leaves: all basal, linear, 

 lanceolate, crenulate, acuminate at the apex. Flowers: heads solitary, 

 yellow; rays truncate, five-toothed. 



A flower very like a real Dandelion, but with totally dif- 

 ferent foliage. The False Dandelion may always be distin- 

 guished by its long ribbon-like leaves, which grow up from 

 the base of the plant and have slightly wavy margins.
