Erigeron Canadensis L

This ubiquitous annual weed is frequently seen in sub-alpine districts and even on the lower glacier moraines. A native of N. America it has now established itself in almost all temperate and hot countries. It is usually taller than the last and glabrous except for a few spreading hairs. The leaves are narrow, entire, or slightly toothed. Flower-heads extremely small, whitish green, very numerous, and forming a long, leafy panicle. Florets minute, the outer ones filiform and slightly tinged with red.

Involucre glandular-hispid, the bracts often reddish. Flower-heads large and handsome, solitary. Ray-florets rose or bright purple; central florets yellow and tubular.

A large N. American genus with a very few European species.

Solidago Virga-Aurea L. Golden-Rod. (Plate XI)

Stems erect, leafy, 6 inches to 2 feet high, nearly glabrous. Root-leaves obovate and stalked; stem - leaves lanceolate, toothed. Flowers in a crowded terminal panicle, bright yellow; each flower-head with a spreading ray of about 10 florets. Alpine forms are sometimes very short.

Leaves lanceolate, undivided; upper leaves narrowed at the apex, acute, denticulate. Ray-florets ligulate. Receptacle paleaceous. Pappus-hairs short, rough.

Dry, bushy places in the plains and sub-alpine situations, as, e.g. the banks of the Lake of Lucerne, but ascending to about 6000 feet. Prefers a limestone soil, and is very suitable for cultivation and for gathering. July, August.
