part of Europe, from the Mediterranean to the Arctic regions, and in central 

 and Russian Asia. Less frequent in England and Ireland, and rare in 

 Scotland. Fl. summer and autumn. It varies much in stature, in the 

 number and size of the flower-heads, and of the florets of the ray, but these 

 are always smaller and more numerous than in the alpine IS., much larger 

 and fewer than in the Canadian JS. 



2. Alpine Erig'eron. Erigeron alpinus, Linn. 

 (Eng. Bot. t. 464, and .E. imiflorus, Eng. Bot. t. 2416.) 



Stock perennial, with erect or ascending hairy stems, 2 to 6 or rarely 8 

 inches high. Radical leaves oblong-lar.ceolate, tapering at the base ; stem- 

 leaves smaller, few, and lanceolate. Flower-heads solitary on each stem, or 

 rarely 2 or 3 in a loose corjnnb, each one at least half an inch in diameter ; 

 the florets like those of the common IS., except that the outer pink or 

 purplish ones are longer, more decidedly ligulate, forming a distinct spread- 

 ing ray. 



In mountain pastures, in northern Europe, Asia, and America, to the 

 Arctic regions, and in the higlier mountain-ranges further south. In Bri- 

 tain, confined to some of the eastern Highlands of Scotland. Fl. summer, 

 rather late. 



3. Canadian Erigeron. Erigeron canadensis, Linn. 

 (Eng. Bot. t. 2019.) 



A stiff, erect annual, 1 to 2 feet high, glabrous, except a few long, spread- 

 ing hairs. liCaves narrow, and entire or sHghtly toothed. Elower-heads 

 very small, green or whitish ; very numerous, forming a long, narrow, leafy 

 panicle. Florets minute, tlie outer ones filiform, not longer than the in- 

 volucre, and slightly tinged with red ; central ones tubular, yellowish-white. 



A native of North America, now established in the greatest abundance as 

 a roadside weed in almost all temperate and hot countries, and appears 

 occasionally as such in England. Fl. summer and autumn. 



V. LIMOSYRIS. LINOSYRIS. 



Habit, involucres, achenes, and pappus oi Erigeron, but the florets are all 

 tubular, yellow, and deeply 5-cleft. 



A small genus, chiefly North American, with two or three Asiatic species, 

 and a single European one. 



1. Common Iiinosyris. Iiinosyris vulgaris, Cass. 

 (Chrysocoma Linosyris, Eng. Bot. t. 2505. Goldilocks.) 



A glabrous, erect perennial, 6 inches to a foot high, with numerous 

 narrow-linear, entire leaves, more or less dotted. Flower-heads in a rather 

 compact, termmal corymb, of a bright yellow. Involucres imbricated, with 

 nimierous narrow bracts shorter than the florets and pappus. Achenes 

 somewhat compressed, and silky. 



In clefts of rocks, and on stony hUls, and especially along the gravelly 

 banks of great rivers in south-central and southern Europe to the Caucasus, 

 not extending to liortheru Germany, although reappearing on the Isle of
