ab E. megastachya distinguitur axillis paniculae glabris callo flavo nee fusco praeditis, ramis parcius divisis, 

 apicera versus simplicibus, foliis angustioribus, caryopsi non globosa, spiculis angustioribus. — Vix dubium 

 puto, Willdenowium cum Poam suam polymorpliam describeret, tres modo nominatas species, megastachyam 

 intelli<*as, Brownii, et hanc Willdenowianam nostram coram habuisse. Nomen igitur, neque hanc solam ob 

 causam, mutandum erat. 



6. E. Brownii ; panicula patula vel contracta erecta, ramis alternis strictis a medio 

 vel paullo inferius divisis, axillis nudis, spiculis lineari-lanceolatis 10-20-floris glauco- 

 viridibus, rhachilla recta denticulata, valvula inferiori ovata acutiuscula trinervi superiori 

 minutim ciliata persistente, caryopsi oblonga striata, culmo ramoso nodisque glabris, 

 vaginis ore barbatis, foliis angustis subinvolutis. N. ab E. in Wight, Cat. n. 1780.—

Caryopsis forma et ramificatione panicula; satis differre videtur ista species a P. polymorpha, Willd. 



[We have retained this name as it is in N. v. Esenbeck's manuscript, and as we are informed both by Dr. 

 Lindley and Prof. Henslow that it was part of Mr. Vachell's, n. 54, which was subjected to his inspection ; 

 all the other specimens of that number, however, which we have seen, belong to our E. Millettii, nor have 

 we ourselves yet seen a single plant of E. Brownii from China.] 



§ 3. Tenellse; panicula capillari scape verticillata, spiculis angustis, valvulis plerumgue tenuibus pellucidis. 



7. E. verticillata ; panicula patula, ramis capillaribus flexuosis, inferioribus verticillatis 

 ad axillas magis minusve barbatis spatio a basi divisis, spiculis linearibus acutis 7-Il-floris 

 variegatis totisve purpuratis, gluma inferiori minuta, valvula inferiori membranacea 

 obtusa trinervi nervis parum prominulis superiori breviori margine scabra, caryopsi 

 obovata compressa lseviuscula, culmo ramoso infracto, foliis linearibus vaginisque glabris, 

 his ore ssepe barbatis. P. de Beauv. N. ab E. Agrost. Bras. p. 508 (cum synon.) —

Species magnitudine et colore spicularum variabilis, sed e spiculis angustis, ramis panicula; gracillimis ssepe 

 contortis, gluma inferiori duplo minore, caryopsi compressa, teneritate quadam et subtilitate partium bene 

 distinct*. Poa punctata, Linn, eadem planta esse videtur, ejus fors minorem pauperemque ahquam sobolem 

 Roxburghius punctata: titulo descripsit, cum ramificationes simplices dixit et spiculas remotiusculas. Si Poa 

 punctata, Linn, eadem ac verticillata, Cav., nomen punctata restituendum est. Ab E. tenella diffcrt 

 spiculis angustioribus, ramis paniculse gracilioribus magis diffusis, gluma inferiori minori, sed Poam tenellam, 

 Roxb., nescio an rectius ad hanc verticillatam referam. 



[With re-ard to Roxburgh's species, we may add to the above : that P. diandra (in E. I. C. Mus. tab. 

 1330) appears to be unquestionably the common form of this plant, or that where the axils of the panicle 

 are scarcely or not at all beardless. His P. punctata (figured in E. I. C. Mus. tab. 839, under the name 

 of P. amabilis) may be a form, but has the branches of the panicle truly simple, and the caryopsis oblong : 

 if belonging to this species, it is a form of the same variety as P. diandra, Roxb. As to P. tenella, Koxb.,
