  • Panicum sphaerocarpon Elliott (1816)

Stiff, light green tufts, 12–20 cm; basal leaves differing from culm leaves and forming a winter rosette. Leaf-sheath light green to purplish, glabrous but margins ciliate. Ligule 0.2–0.5 mm, ciliate, hairs sparse. Collar hairs long, tubercle-based. Leaf-blade 3–10 cm × 7–13 mm, firm, rather thick, broadly linear to elliptic-oblong, narrowed above, ribs fine, inconspicuous; abaxially smooth, adaxially finely scabrid on ribs; margins thickened, scabrid, ciliate near cordate base, tip acute to acuminate. Culm erect to spreading, nodes appressed-pubescent, internodes glabrous. Panicle 5–8 × 2–4 cm; branches very slender, glabrous; pedicels almost filiform, tipped by solitary spikelets. Spikelets < 2 mm, green to purplish, ovoid, subacute. Glumes very unequal; lower c. 0.5 mm, membranous, glabrous, obtuse, upper = spikelet, 7-nerved, elliptic-ovate, subacute, puberulent. Lower floret Ø: lemma similar to upper glume, 7-nerved; palea 0. Upper floret ☿: lemma 1.6–1.8 mm, elliptic, subacute, glabrous, faintly striolate, white, shining; palea narrower; anthers 0.3–0.4 mm; gynoecium: ovary c. 0.3 mm, stigma-styles c. 1.8 mm, stigmas deep purple; caryopsis not seen.
