Sect. II. Privglcochloa Scribn.* (as a genns). First empty glnnie of the pis- 

 tillate spikelet linear, little shorter than the second; flowering glume of the 

 fertile flower shortly 3-cleft; the 2-3 sterile ones many awned above. O. 

 Pringlei (Scribn.) Hack. (Fig. 5.) Mexico. 



The characters of OrcuttiaY-Asey, should be modified as follows : Cfpspitose, 

 spreading annuals with large, many-flowered spikelets in terminal spikes ; flow- 

 ering glumes broad, many -nerved, and toothed or lobed at the broad apex. 



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 

 boat-.shaped, 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. Cladoraph is 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 Ceylon to the mouth of the Zambezi ; a grass with rigid, 

 convolute leaves. 



AntJi.ocJiloa Nees (in PI. Meyen, 164). (Stapfia, and Neostapfia Davy, and 

 Davycila Hack. ) Panicles densely flowered, ovoid or cylindrical and spikelike; 

 spikelets 2-5-flowered; flowering glumes thin membranaceous, broad, flabelli- 

 form, finely toothed and minutely ciliate-fringed, awnless ; lower glumes narrow, 

 sometimes wanting. 



Species three, two South American; one, A. colusana (Davy) Scribn., from 

 California. 



After Lasiochloa Kunth, add as a synonym Triboliuvi Desv.

* (Bot. Gaz. 21 : 1.37, plate 13.) MoncBCiou8,staminate and pistillate spikelets unlike. Staminate 

 spikelets one-flowered, in racemose, unilateral spikes on erect toranclies; pistillate spikelets on 

 short, basal branches: flowering glumes 3-awned, with rudimentary, many-awned empty 

 glumes above. Low, stolonit'erous perennial.
