 Pastor G. Kiikenthal.

GRAMINE.E. 



Danthonia australis, Buchanan. 



Growing in light sandy loam and thickly covering the

 Hook, f., var. petiolata, T. Kirk, and Gel. lyallii, Hook, f., 

 grow through it here and there ; or there may be a few plants 



* The plant referred to here is probably the form described by Potts 

 as G. alpina.
