Species two, in Southern California. After Diplachne insert: Pogochloa Moore. Spikelets laterally compressed, 5-flowered, two-ranked on long panicle branches (the rows approximate below), sessile. Empty glumes unequal, the lower 8-5-nerved, the upper with 9 strong nerves. Flowering glumes , keeled, 3 nerved, shortly two- toothed or almost entire, with a long, erect awn between the teeth. Species one (P. hrasilieusis Moore). In the state of Matto Grosso, Brazil. Under Eragrostis there is to be added under Sect. I. C'ataclastos. Cladoraphis French, (as a genus), is a one flowered depauperate form of E. spinosa Nees. Ipnum Phil, is reduced to Diplachne. After Eragrostis add: Halopyrum Stapf. Spikelets many-flow- ered, in narrow panicles with a hairy axis breaking up at maturity. Empty glumes shorter than the flowering ghimes, the lower 3- the upper 5-nerved. Flowering glumes firm in texture, keeled, 3-nerved, mucronate- pointed. Caryopsis broadly furrowed in front. In other respects like Eragrostis, with the section Platystachya of which it is closely related. Bentham placed the species belonging here in Eragrostis, Sect. Seleros- tachija, a conglomeration of species not closely related, which ought to be completely broken up. Species one {H. mucronatum Stapf., Brizopyram mucronatum Nees, accord- ing to ^i'AY>f.^Uniola nnicronata L. V) distributed along the coast of the Indian Ocean from
