Stems tufted, finally rooting at the lower nodes and usually sending up erect branches up 
to 1.5 dm. tall; leaf-sheaths ciliate on the margins, otherwise glabrous, or sparingly pubescent; 
blades glabrous or pubescent, 2-4 cm. long, 2-3 mm. wide; panicle of 5-12 slender racemes, 
1.5-3 cm. long; spikelets lanceolate, 2.5-3 mm. long, rarely smaller or larger, acuminate, 
the outer scale 3-nerved, the lateral nerves hirsute, the fruiting scale thin, delicate, hyaline, 
usually longer than the outer scale, attenuate at the apex.

Herb. 12: 199. 1909. 
Reimaria oligostachya Munro ; Benth. Jour. Linn. Soc. 19: 34. 1881. 
Smooth and glabrous. Stems compressed, 4-8 dm. long; leaf-sheaths compressed; 
blades erect or ascending, 5-15 dm. long, 2-4 mm. wide; racemes in pairs at the summit of 
stem, or sometimes with an additional one a short distance below, 3-7 cm. long; spikelets 
broadly lanceolate, about 5 mm. long, about twice as long as the rachis-internodes, the outer 
scale 9-nerved, the 4 nerves on each side close together and rather distant from the midnerve, 
the fruiting scale equaling or a little shorter than the outer scale, acute, ovate-lanceolate.

Annual or perennial grasses, varying much in habit, the stems tufted or single, erect to 
prostrate, and often arising from creeping rootstocks. Racemes 1-sided, 1-many, scattered, 
opposite, or verticillate, or in pairs at the summit of the stem, the rachis usually winged, the 
wings green or colored, flat, or sometimes inrolled on the spikelets. Spikelets articulated below 
the empty scales, 1-flowered, alternately disposed in 2 rows, single or in pairs, with the back of 
the fruiting scale turned toward the rachis, orbicular to elliptic or ovate, usually obtuse, 
rarely acute or acuminate, plano-convex, or ‘sometimes flat on both surfaces. Scales rarely 2 
(the first and second wanting), usually 3 (the first wanting), or sometimes 4, with the first 
usually small or reduced to a mere rudiment, rarely large, the second and third scales and rarely 
the first 3-several-nerved, or sometimes 2-nerved by the suppression of the midnerve; fruiting 
scale with its opening turned away from the rachis, chartaceous in flower, usually becoming 
indurated in fruit, commonly obtuse or rounded at the apex, rarely acute, enclosing a palet 
of similar texture and a perfect flower. Stamens 3. Styles distinct, often elongate. Stigmas 
plumose. 
Type species, Panicum dissectum L.
