Reimaria oligostachya Munro ; Benth. Jour. I^inn. 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.
