Culms tufted, slender, 25 to 40 cm tall; leaves clustered at the 
base; blades glabrous, thick, erect, flat or folded, 10 to 20 cm long,

86. ISACHNE R. Br., Prodr. Fl. Nov. Hoil. 196. 1810 
Spikelets obovoid to subglobose; glumes membranaceous, about 
equal and as long as the fruits or at maturity exceeded by them; 
lower floret perfect or staminate, its lemma and palea indurate and 
similar in form and texture to those of the upper floret; both florets 
(or fruits) plano-convex, obtuse, equal in size or the upper shorter, 
the pair usually remaining attached by the minute rachilla joint 
between them. Mostly perennials with firm blades and open or 
contracted panicles. Jsachne polygonoides is exceptional in that the 
lower floret is unlike the upper. In all the species the lower floret 
of some of the spikelets may fail to perfect agrain. When sterile the
