YELLOW OR YELLOWISH FLOWERS 
Sneezeweed. Swamp Sunflower (Helenium autumnhle). 
Composite family. August to October. 
A showy perennial, sometimes reaching six feet. The flower- 
heads (one to two inches broad) have drooping, wedge-shaped, 
notched, pistillate rays. The disk (of perfect flowers) is globular, 
yellow. The leaves are mostly toothed, lance-shaped to egg- 
shaped. Banks and wet ground, sometimes cultivated. If shut 
up in the -house with Helenium, one susceptible to " hay 
fever " will acknowledge the justice of the popular name and 
quickly consign to the ash-heap its decorative but unfriendly 
blossom. 
Wild Lettuce {Lactuca canadensis). Composite family. 
June to October. 
A branching biennial or annual, four to six feet high or more. 
The flowers, with strap-shaped, perfect florets, resemble dande- 
lions, not over one-fourth inch broad, in open panicles. The 
lower leaves are like those of the dandelion, the upper lance- 
shaped. Rich ground. A rather common species of similar 
appearance, but may be twice as high and with a bluish to 
cream-colored blossom, is Blue Lettuce (L. spicata). This leafy 
plant, with large, compact panicle, grows very tall by the road- 
side near South Harpswell, Maine, and about Woodstock, 
Vermont. Another not uncommon species is Prickly Lettuce 
(L. scariola) with yellow blossoms, prickly stem, leaves pinnately 
cut, and hairy midrib. The variety integrdta, more common in 
eastern New England, is distinguished by its oblong leaves, not 
deeply cut. This grows in waste places everywhere.
