Misc. Compound of Greek erion, wool, and caulos, a stalk, from the woool at the base of the scape in the original species (Fernald, 390). Stone, in 1910, says, "Wet swamps in the Pine Barrens and Cape May district; frequent." The early flowering large grayish heads and short leaves distinguish this fine species from (E. parkerii), while E. septangulare (= E. aquaticum) is usually smaller and later in flowering." (p 325) Note then, that this is generally the first pipewort to bloom in the heart of the pine barrens.
