acute, each 5-7-nerved, first 9 mm. long, second 11 mm. long-; 

 floral glume 9-11 mm. long, strongly scabrous, a few hairs near 

 the margins at the base, linear, 7-nerved, central nerve excurrent 

 below the bifid tip, an awn 6-10 mm. long; palea linear before

Spikelets 3-5-flowered in a narrow strict sparingly branched 

 ])anicle, one or two of the uppermost flowers sterile, rachilla very 

 easily articulate between the flowers. Empty glumes very unequal, 

 coriaceous, keeled, first narrow, acute, 1-nerved, second larger, 

 broader, ovate, acute or mucronate, 5-nerved ; floral glume broadly 

 ovate, round on the back, coriaceous, shining, 3-nerved, the nerves 

 united at the apex in a strong abrupt or awl-shaped tip ; palea 

 shorter, rigid, 2-keeled. Stamens 2, rarely 1. Styles short, dis- 

 tinct. Grain very large, obliquely ovoid, obtusely pointed, rather 

 longer than the floral glume; pericarp not adhering to the seed. 

 Tall erect perennials witli flat blades. 



There are two species, one 2>eculiar to eastern North America, 

 the other to Japan ; nearly allied to Melica, but the floral glumes 

 have only three nerves and are hardened round the grain, which 

 usually exceeds them, and the stamens are reduced to two or one. 

 The habit is much that of the section Bromelka of tlie genus 

 Melicd.
