ab E. rnegastachja distinguitur axillis paniculse glabris callo flavo nec fusco prasditis, ramis parcius divisis, 

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

 puto, Willdenowium cum Poam suam polymorpham describeret, tres modo nominatas species, meg ast achy am 

 intelligas, 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-Ianceolatis 10-20-floris glauco- 

 viridibus, rhachilla recta denticulata, valvula inferior! 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 dift'erre 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. Tenella; ; panicula capillari scepe verticillata, spiculis angustis, valvulis plerumque tenuibus pellucidis. 



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

 ad axillas magis minusve barbatis spatio a basi divisis, spiculis linearibus acutis 7-1 1-floris 

 variegatis totisve purpuratis, gluma inferiori minuta, valvula inferior! membranacea 

 obtusa trinervi nervis parum prominulis superiori breviori margine scabra, caryopsi 

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

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

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

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

 distincta. Poa punctata, Linn, eadem planta esse videtur, cujus fors minorem pauperemque aliquam sobolem 

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

 punctata, Linn, cadem ac verticillata, Cav., nomen punctata! restituendum est. Ab E. tenella diti'ert 

 spiculis angustioribus, ramis panicula: gracilioribus magis diffusis, gluma inferiori minori, sed Poam tenettam, 

 Roxb., nescio an rcctius ad hanc verlicillatam referam. 



[With regard 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, tinder 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, Roxb.,
