Perennial, loosely tufted herb; stems erect, 10-25 cm tall.
Leaves:
Located on the lower part of the stem, nearly circular in cross-section, tapered, lacking cross-walls.
Flowers:
Inflorescence of 1 to 3, terminal heads of 2 to 5 flowers, the flowers lacking involucral bractlets; perianth segments green or light brown with wide translucent margins, 3.5-4.5 mm long, egg-shaped, subequal, blunt; stamens 6; anthers 0.4-0.7 mm long, shorter than the filaments; bracts leaflike, usually slightly longer than the inflorescence.

Notes:
Plants from N America and E Asia have sometimes been separated into var. americanus. The taxonomic status of this variety is doubtful.
If more than one illustration is available for a species (e.g., separate illustrations were provided for two subspecies) then links to the separate images will be provided below. Note that individual subspecies or varietal illustrations are not always available.
