TRIANDRTA. DIGYNIA. Agrostis. 



I 



sheathing part, and roughish. Sh. Scales long, pointed. Panicle 

 a delicate pale green, about o inches lon_ 

 1 inch, but little expanding. Calyx valves unequal, the outer 

 serrulated all along the keel, tte inner only towards the point. 

 Bloss. inner valve deciduous, more like a* very short and slender 

 hair than a husk, and so minute that it is with difficulty found. 

 Avon jointed, very slender, deciduous, somewhat longer than the 

 blossom, and fixed beneath its middle. 



This I apprehend is what has sometimes been considered as an 

 awned Agr. alba ; it is clearly what has been called an awned 

 Agr. taf Maris, (meaning our vulgaris,) but it is sufficiently dis- 

 tinct from both.

coloured : bloss. outer valve with a jointed awn on 

 its back. — Gmcl. Hairy at the base. St. 



Scheuch* prodr. 4. 1. 



About 9 inches high, just sensibly rough to the touch. Root- 

 leaves numerous, like bristles, in bundles, about I the height of 

 the straw, smooth when old. Sheath-scale long, pointed. Panicle 

 2 to 3 inches long, purplish blue : branches not spreading, 

 thickly set with florets, seldom more than £ inch long. Calyx 

 valves unequal, both smooth below, but serrulated upwards; 

 nearly twice as long as the blossom. Bloss. surrounded at the base 

 by a few fine short hairs : outer valve with 2 or 4 minute pro- 

 . jecting points at the end : inner valve very minute, not longer than 

 the germen. Awn jointed, twice the length of the blossom, 

 and fixed near to its base. The hairs at the base of the blossom 

 distinguish this from every other British species.

littora'lis. A. Panicle somewhat spike-like: calyx husks awned. 



PLATE XXIII. 



From 5 to 7 inches high; often several flowering stems from 

 the same root. Straw bent at the bottom, straight upwards, 

 smooth. Leaves slender, rough, 2 or 3 on the stem, sheathing ; 

 sheath-scale spear-shaped. Panicle compact, spike-like, li to l\ 

 inches long, hardly { inch broad, pale green, branches extremely 

 crowded, close. Calyx, husks the lower half rough on the keel, 

 upper half smooth, awned. Avons 3 times as long as the husks, 

 fixed below its point, 1 to each husk, straight, diverging. Bloss* 

 2 valves, smooth, awnless, one much broader than the other ; I 

 v the length of the calyx. This is the only British species with 



the awns on the calyx*
