A forma vulgari specimina a nobis lecta differunt: pa- 

 nicula multo minori, glomerato-contracta , roseo-flavescente, 

 ramis omnino glaberrimis, nervö marginali glumarum valde 

 prominente, flosculis remotiusculis, culmis geniculatim adscen- 

 dentibus, foliis inferne turfoso-collectis. Num vere distincta 

 sit, nescio.

Hab. locis siccis regionis inferioris ins. Cha- 

 tliam et Charles (Ipse et Darwin) et in insula 

 Albemarle (Macra?). 



Specimina, quae in insulis duabus legimus, inter se non- 

 nihil differunt statura et forma. Quae in insula Cbatham 

 crescentia invenimus, panicula angusta dense contracta fere 

 spiciformi, culmis digitalibus erectis, vaginis superne longe et 

 sparsim pilosis, foliis brevissimis strictis convolutis singularia; 

 quae in insula Charles panicula verticillatim interrupta, culmis 

 valde casspitosis geniculatim adscendentibus, interdum sub-
