Habit | Herbs, perennial, 10–20 dm. | Herbs, perennial, rhizomatous, 3–15 dm. |
Rhizomes | long- creeping. |
3–4 diam., nodes not swollen, smooth. (often developing filiform leaves in running water). |
Culms | erect, 2–5 mm diam. |
erect, terete to compressed, 5–12 mm diam. |
Cataphylls | several. |
1–3, straw-colored to pink, apex acute. |
Leaves | blade absent. |
basal 0, cauline 2, long capillary leaves often found in fascicles on rhizomes; auricles 0.3–0.5 mm, apex rounded, scarious; blade terete, 50–70(–100) cm × 2–5 mm, those of proximal leaves usually overtopping inflorescences, distal leaves usually inflated bladeless sheaths, occasionally absent or withll well-developed blades. |
Inflorescences | lateral, many flowered, loose; primary bract barely exceeding to many times longer than inflorescence. |
terminal panicles of 20–100 heads, 4–15 cm, branches erect to ascending; primary bract erect; heads (3–)5–13(–25)-flowered, hemispheric to turbinate, 6–8 mm diam. |
Flowers | variously pedicellate; bracteoles membranous; tepals greenish to pale brown, lanceolate, 3.5–5 mm; inner series loosely subtending capsule at maturity, usually slightly shorter, margins scarious to clear, acutish; stamens 6, filaments 0.3–0.9 mm, anthers 1–2.5 mm; style 1–1.5 mm. |
tepals straw-colored or reddish, lanceolate, 2.3–3.2(–4) mm, nearly equal, apex acuminate to awned; stamens 6, anthers 1.5–2 times filament length. |
Capsules | dark brown, 3-locular, oblate to narrowly ovoid, 3–4 mm, nearly equal to perianth. |
straw-colored, 1-locular, ovoid, 2.3–3.3 mm, equaling perianth, tapering to subulate tip, valves separating at dehiscence. |
Seeds | dark amber, oblate to ellipsoid, 0.5–0.8 mm. |

Discussion | The proximal culm leaf of Juncus militaris usually has a single well-developed leaf blade that overtops the inflorescence; and the distal leaf usually is an inflated bladeless sheath above it. An Alabama report, based on a single specimen collected by Drummond (not seen), at GH and MO, was discounted by Coville (and here). Coville believed the location and possibly the collector were wrongly attributed to this collection (see letter from Coville to Small at NY).
