Plants annual, 0.5–6 cm tall, unbranched. |
|
capillary; basal. |
|
1–4(7) flowers in a terminal cluster; flowers subtended by 2 bractlets; tips acute. |
|
tepals usually 4, pale green or pink; stamens 2(3); filaments 0.6–0.9 mm; anthers 0.3–0.4 mm; styles 0.1– 0.3 mm. |
|
usually elliptic to oblong, equaling or longer than the tepals, pale green or pink. |

Juncus acutus |
|
|
|
|
|
Damp depressions, stream banks, sunny floodplains. 1000– 2000m. BR, ECas. CA, NV, ID, WA; south to Mexico. Native. Plants with few seeds per capsule have larger seeds, and thus some specimens might suggest J. capillaris, but there is no overlap. Juncus capillaris always has fewer than 10 seeds per capsule. |
