    Because of their many white-to-gray button-like heads, the smallish bog buttons are easily discovered when searching for them along wet roadsides. They might be confused with Eriocaulon or Syngonanthus. There are five species of Lachnocaulon in Florida (Wunderlin, 2003). Bogbuttons are located throughout the southern and southwestern parts of the US (Kartesz, 1999).

    Bog buttons are emersed plants. Roots dark, thin, branched; stems tuft-forming, hairy, to 16 in. tall; leaf blades grass-like, at stem base, arranged in spiral clusters, narrow, tapering, to 2 in. long, much shorter than flower stalks; inflorescences button-like heads, white to gray, at the tips of long stems, comprised of many tiny, densely-clustered whitish-to-grayish flowers.
