study of the subvarieties grandiflora (Hack.), tenuifolia (new), and a third probably corre- 

 sponding to Hackel's glaucescens. The new subvariety is xerophytic and generally associ- 

 ated with halophytic conditions; fairly densely caespitose; rhizomes short and more or less 

 curved and ascending from the base; leaves slender and dark glaucous green, with a "bloom;" 

 panicle more compact than in grandiflora: internodes rough; spikelets fewer, but the individual 

 glumes large and as numerous as in grandiflora, with shorter awns. — I. F. Lewis.
