one valve, andthe place of the second valve is occupied by a long 

 twisted arista. In the male one it is two-valved. 

 Obs. It is a coarse grass. Cattle are not fond of it. 



11. A. pertiisiis. Linn, Sp. PI. ed. Willd. iv. 925. 



Near the root creeping. Spikes from four to eight, digitate, pe- 

 dicelled, exterior valve of the sessile, awued, hennaphrodile calyx 

 with a pit on the back; male or neuter ccrol oue-valved 



Holcus pertusus. K6n. Linn. Maul. 301. 



Is found on old pasture ground, which is generally shaded by trees. 



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

 hemded.-Leaves small, ciliate; ?«ow^As of the sheaths bearded— 

 Spikes from four to eight, in other respects exactly as in the lastspe- 

 cies.—Fhzi-ers, the specific mark is to be found in the pit of the exte- 

 rior valves of the calyx of the hermai)hrodite flowers, as in A. stric^ 

 tus, 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 

 awuless. 



Obs. I should doubt this being Konig's Holcus pertusmii he had 

 not pointed it out to me himself.

 Leaves the same.-S;,fc from four to eight, short-pedicelled, in-

 they are as m the last described species.-The flowers resemble 

 those of that species, but arc a little more r^moi^.-Cahx and Corol
