AGROSTIS SIMULANS, Ilemsl. 



Gramine^, Tribe Agrostide.e. 



A. simulans, JlemsL (.<?p, nov.) ; A. alhce var. stoloniferce simillima, 

 differt ligula breviore, raraulis inflorescentise divaricatia glumis multo 

 minns scariosis, etc. 



Hab. St. Helena, Burchell, 1810; HooJcer, 1840 ; Melliss, 1863. 



This Grass so strongly resembles the stoloniferous variety of AgrosHs 

 alba in many particulars that it is difficult to draw up a description 

 that would not include the two. The loose inflorescence, with nearly 

 horizontal branches, is the most striking chai-acter of J., simulans^ and 

 the glumes are almost wholly opaque. These differences may be due to 

 local causes ; still the late General Munro has marked it ' ^ood species, 

 and there is nothing among the num.erous specimens at Kew, referred 

 to A. alia, with which it agrees except in a general way. The only 

 St. Helena plant previously ascribed to Agrostis is A. purpiirascens^ 

 Roxb., which is doubtless Sporohohis indiciis. — W. B, Hemsley.
