Noteworthy Characteristics

Lachnocaulon anceps, commonly called whitehead bogbutton, is a herbaceous, clump-forming perennial native to peat bogs, sandy seeps, pine savannas, and other moist, open areas of the southern United States coastal plains. The tufted clumps of basal foliage can reach up to 3" tall with a similar to slightly wider spread and are made up of narrow, lanceolate leaves. Rounded flower heads reaching up to 0.25" wide and made up of tiny, white flowers are held above the foliage on wiry, leafless, upright flowering stalks. The flowering stalks emerge from mid-spring to mid-summer, and can reach between 4-15" tall.

The specific epithet anceps means "two-sided", in reference to the flowering stalks which can have two sides but are more often ribbed with 4-5 sides.

The common name whitehead bogbutton refers to the shape and color of the inflorescence as well as the preferred habitat of this species.
