26 CLXXII. GRAMINE^. (J. D. Hooker.) [Isachne. 



Zeyl. 110, t. 47, f. 3, is not an Isachne, but resembles an Eragrostis ; and that 

 Plukenet's Pliyt. t. 300, f. 2. (in Herb. Sloane) is E. ciliaris from the Malabar 

 Coast. Triinen has pointed out (Journ. B )t. xxxiii. (1885) 271) that the " Mene- 

 ritana of the Cingalese is not an Isachne, but is applied to Panicum miliare and 

 ps'dopodium.

Stems 2-6 in. Leaves spreading, rather rigid, striated ; midrib slender. Spilce- 

 lets as in I. australis; pedicels smooth or rough ; gl. 1 and II scabrid or setulose, 

 nerves many, faint; III glabrous ; IV pubescent. This again is perhaps a var. of 

 /. auxtralis, of lower stature with more rigid scaberulous strongly margined leaves, 

 sometimes ciliate at the base, and smaller panicles with shorter pedicels.
