This is about a foot tall, with smooth, hollow flower-stems, smooth leaves, and rather small yellow flowers, not particularly pretty. The " gone-to-seed " flower-heads are, however, very conspicuous, for they are nearly an inch and a half across, and each seed is tipped by a little silvery paper star, the effect before the wind carries them away being exceedingly pretty, a good deal like a Dandelion puff. This grows in the Grand Canyon on the plateau.

There are many kinds of Sonchus, natives of the Old World.
