Exemplum nostrum, a Vachellio lectum, fructu delapso jam ramulis panicute gaudet paullo magis patulis, 

 valvulisque interioribus, ut in E. pectinacea persistentibus rigidulis patulisque, ssepe subtrifidis. Folia linea 

 latiora, attenuata, rigidula, laevia, glaucescentia, convoluta, circa os vaginae barbata. Paniculm rami In 

 axillis scabridi. Valvula inferior trinervis, pallida. 



[Our specimens from Mr. Millett are much less advanced : the panicle is very contracted, cylindrical, and 

 composed of short, crowded, adpressed, compound, alternate branches, as described by Roxburgh. The 

 spikelets are tinged with purple. The glumes and lower valvelet of the florets are minutely str.goso-pubes- 

 cent, but otherwise glabrous and without cilise on the margin.] 



§ 2. Megastachya; ; paniculatce, paniculm ramis validiusculis, spiculis ovatis oblongis lanceolatisve, valvulu 



haud pellucidis. 



2. E. amabilis ; panicula racemoso-composita patula erecta, ramis plerisque solitaries 

 basi glabris prope a basi divisis circumscriptione lanceolata, pedicellis longiuscuhs, spiculis 

 coloratis ovatis 16-24-floris, flosculis arete imbricatis inferioribus deciduis, valvula infenori 

 late ovata acuta trinervi membranacea, caryopsi ovata, culmo ramoso adscendente nodis- 

 que glabris, ligula brevissima, foliis lanceolato-linearibus glaucis laevibus basi ciliatis.

Gramen perelegans, spiculis brizoideis purpureo pallidoque variis.—In adumbranda Poa sua uniloide Retzius 

 ante oculos habuisse videtur spiculam ex inferiore parte paniculse paucifloram, cui glumae jam delapsse 

 deficerent. Turn vero flosculorum duorum inferiorum inferiores valvulas glumas esse, sive calycem, existi- 

 manti, obstabant valvute utriusque flosculi superiores, quas nisi calycem alteram interioremque declararet, 

 non habebat quibus explicaret. 



3. E. megastachya; panicula racemoso-composita patente erecta, ramis inferioribus 

 subverticillatis alternisque in axillis et ad ramificationes barbatis, reliquis omnibus alternis 

 prope a basi divisis pedicellis brevibus, spiculis lineari-oblongis pallidis aut plumbeo- 

 viridibus 15-25-floris, valvula inferiori obtusa subemarginata brevissime mucronata trinervi 

 nervo laterali prominulo superior! ciliata, caryopsi globosa, culmo ramoso adscendente
