CynoJonti Dactylo haud absimile. Eachcs Digitari^, Spicula^ 

 minutse, satis conformcp, indumento aliquotenus variantes. Fructus 

 sensim acutu?, fere Isevis, saepe pallidus. Totum Paspali genus ad 



Panicum facillime trahes. 



Pamcum parviflonun ("R. Br. Pr. 192) elocis sequentibus novi. 

 Parramatta et Blue Mountains (WooUs), New England (C. St.), 

 Clarcnce-River (Wilcox), Brisbane's River (F. M.), Rockiiampton 

 (Thozet), IIerbert's Creek (Bowman). Gramen perenne. Radix 

 fil)roe:a. Ligula membranea, satis procera, haud ciliosa. Fructus 

 angustus, saturate fuscus v. nigrescens, nitidus, subtilissime rugu- 

 latus. Speciem ab anterlore discriminavimus statura robustiore 

 altioreque, multitudine spicarum, rachibus flexuosis angustioribus, 

 spiculis longius pedunculatis, bractea exteriore evidentius evoluta. 

 Nihiloininus varictates tenellai oligostachj^ fere sequa facilitate ad 

 P, tonuiflorum ducendse sunt. Paspalum pedicellatum (CoU. Wigbt, 

 2310) et P. Wallichianum (W. et A. in Steud. Glum. i, 41), Pani- 

 cum multibrachiatum (Hoclistett. in Steud. Glura. i. 74) et P. 

 polygonatum (Schrad. iu Scliult, Mantiss. ii. 256) hanc nostram 

 speciem valdo approximant. Gramen quoque persimilc nisi varie-

 P. ramulare (Trin. Dissertat. ii. 244), quantnm diagnosis brevis- 

 sima docet, fortasse ad P. parviflorum referendum.

 pedunculorum ultimorum imprimis divergit, quo modo habitum
