Subspecies 2 (1 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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).
