Description
Chelone glabra is a herbaceous plant found in wetlands and riparian forests of eastern North America with opposite, simple leaves, on stout, upright stems. The flowers are white, borne in late summer and early fall. It can be used as a method of birth control, as used by Abenaki people.
Its native range extends from Georgia to Newfoundland and Labrador and from Mississippi to Manitoba.
It is the primary plant that the Baltimore Checkerspot Butterfly will lay its eggs on (although the butterfly to some extent will use a few other species).
C. glabra is also a foodplant for the sawflies Macrophya nigra (Norton) and Tenthredo grandis (Norton) (Hymenoptera: Tenthredinidae), (Stamp, 1984).
A flea beetle in the genus Dibolia (Coleoptera: Chrysomelidae) has also been shown to feed on C. glabra (Wilcox, 1979).

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
