Andropogon. triandria digynia. 259 



dite calyx with a pit on the back ; male or neuter corol one- 

 valved. 



Holcus pertusus. Kon. Linn. Mant. 301. 



Is found on old pasture ground, which is generally shaded 

 by trees. 



Culms creeping near the base, &c. as in the last two species ; 

 joints bearded. Leaves small, ciliate; months of the sheaths 

 bearded. Spikes from four to eight, in other respects exact- 

 ly as in the last species. Flowers, the specific mark is to be 

 found in the pit of the exterior valves of the calyx of the 

 hermaphrodite flowers, as in A. strictus, and A. punctatus, 

 to be described ; an arista occupies the place of the second 

 valve of the corol ; the valvelets of the calyx are both awnless. 



Obs. I should doubt this: being Konig's Holcus pertusus , 

 if he had not pointed it out to me himself.

 remote. Calyx and corol the same as in A. scandens.
