Arundinaria tecta

(Walter) Muhl.
Endemic
Synonyms: Arundinaria gigantea subsp. tecta
Treatment appears in FNA Volume 24. Treatment on page 18.

Rhizomes normally horizontal for only a short distance before turning up to form a culm, hollow-centered, air canals present. Culms usually shorter than 2.5 m tall, to 2 cm thick; internodes terete in the vegetative parts. Culm leaves persistent to tardily deciduous; sheaths 11-18 cm; fimbriae 1.5-8.5 mm; blades 2.5-4 cm. Topknots of 9-12 leaves; blades 20-30 cm long, 1.8-3.2 cm wide, lanceolate to ovatelanceolate. Primary branches usually 50+ cm, basally erect and distally arcuate, terete, with 3-4 compressed basal internodes, basal nodes developing secondary branches, lower elongated internodes terete in cross-section. Foliage leaves: abaxial ligules fimbriate to lacerate, sometimes ciliate; blades 7-23 cm long, 1-2 cm wide, coriaceous, persistent, evergreen, bases rounded, abaxial surfaces densely pubescent or glabrous, strongly cross veined, adaxial surfaces pubescent. Spikelets 3-5 cm, with 6-12 florets, the first occasionally sterile. Glumes unequal, glabrous or pubescent; lowest glume obtuse to acuminate or absent; lemmas 1.2-2 cm, glabrous or nearly so. Caryopses oblong, beaked, a rudimentary hooked style-branch present below the beak. 2n = unknown.

Discussion

Arundinaria tecta grows in swampy woods, moist pine barrens, live oak woods, and along the sandy margins of streams, preferring moister sites than A. gigantea. It grows only on the coastal plain of the southeastern United States.
