1343 PESTUCA DUBIUSCULA. 



exceptions to a oomital ge- 

 nerality do not exhaust the 

 uncertainties about this 

 grass. It has -been so con- 

 fused with ovina on one side, 

 and with rubra or areiiaria 

 on the other side, that per- 

 haps the better course now 

 would be to treat duriuseula 

 and arenaria as two grasses, 

 any counties for which might 

 properly be recorded de novo ; 

 provided, of course, this were 

 done by botanists prepared 

 to discriminate these two 

 from each other and also 

 both of them from ovina.

 N.B. This grass, brought into 



the gardens from the sandy 

 coast of Lincolnshire, and 

 kept under flower-pot cul- 

 ture, became so like the 

 prdinary inland F. duriuseula 

 as to be scarcely separable 

 from the latter. Inland lo- 

 calities are rejected ; ex. gr. 

 Andover ; Clarke Flora.
