Exeraplum nostrum, a Vachellio lectum, fructu delapso jam ramulis panicula? gaudet paullo magis patulis, 

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

 latiora, attenuata, rigidula, Isevia, glaucescentia, convoluta, circa os vagina barbata. Paniculce 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 strigoso-pubes- 

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



§ 2. Megastachyaj ; paniculatce, paniculce. ramis validiusculis, spiculis ovatis oblongis lanceolatisve, valvulis 



haud pellucidis. 



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

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

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

 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 delapsffi 

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

 manti, obstabant valvula? utriusque flosculi superiores, quas nisi calycem alterum 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 superiori ciliata, caryopsi globosa, culmo ramoso adscendente 

 nodisque glabris, vaginis glabris ore barbatis, foliis lanceolato-linearibus margine serrulato-
