About Thread-leaved Beakseed (Bulbostylis capillaris) Bulbostylis capillaris is a species of sedge known by the common names densetuft hairsedge and threadleaf beakseed. It is native to much of North America, South America and the West Indies from Canada to Bolivia. Bulbostylis capillaris grows in many types of habitat, generally in moist areas such as streamside meadows. It is an annual herb which is somewhat variable in appearance but generally takes the form of a small, upright tuft of green herbage growing close to the ground. There are several stems surrounded by thready, thin leaves. The inflorescence occurs at the tip of the stem and is composed of tiny spikelets which are green washed with rusty red. The fruit is about a millimeter long.
