Annual herb from a well-developed taproot; stems erect, numerous, simple, rough-hairy or sometimes smooth, often woolly at the base, 3-20 cm tall.
Basal leaves linear, tapering towards the base, smooth or sparsely hairy, 2-10 cm long, 0.3-1.5 mm wide, entire; stem leaves lacking.
Inflorescence of dense bracteate spikes, the spikes elongate, 1-10 cm long, smooth; corollas green, 4-lobed, the lobes less than 1 mm long, erect to reflexed, some plants with nonfunctioning stamens while others with reduced or nonfunctioning pistils; bracts broadly egg-shaped, spurred, equal to the sepals, 2 mm long.
Capsules, egg-shaped, 2-3 mm long; seeds 4, or sometimes 5 or 6, elliptic-oblong, 1.3-2 mm long, pitted at maturity.
Specimens of P. bigelovii and P. elongata annotated and cited in Bassett (1973) were not readily distinguishable in the herbaria studied. This was also noted by Cronquist (1984).
