1. T. caninum (Huds.) fibrous rooted Wheat-grass. Engl. Bot, 

 t. 1373. Pam. Gr. t, 62. 



Locality, In woods and on hedge-banks. P. El. July. Area* 

 1, 2, 3, 4, 5. Reported in all the Districts. The stems varying in 

 height from 2 to 3 feet, grow more or less tufted, not at long dis- 

 tances like those of T. repens. Leaves glossy, dark green, roughish 

 on both surfaces. Ligule short, obtuse. Spike long and slender, 

 sub-cylindrical. Spikelets usually 4 or 5 -flowered. Glumes distinctly 

 3-ribbed, with a terminal awn. Outer palea terminating in a slender 

 rough awn, generally much longer than itself. Local and rather 

 scarce in Wilts, and far less common than T. repens, but distinguished 

 from it by the want of a creeping rhizome. 



2. T. repens, (Linn.) creeping Wheat-grass, or Couch-grass. 

 Engl. Bot. t. 909. Pam. Gr, t. 62. 



Locality. Fields and waste places, especially in arable land, where 

 owing to its creeping habit, it is among the most troublesome of 

 weeds. P. El. June, July. Area, 1, 2, 3, 4, 5. Distributed throughout 

 all the Districts. Root extensively creeping, and most difficult of 

 extirpation. Stems 2 feet high, erect. Leaves of a dull glaucous 

 gTeen, upper surface clothed with long soft hairs, rough on the ribs of 

 the under surface, and at the edges. Ligule short, obtuse. Spike 

 compressed, 6 to 8 inches in length. Spikelets oval or oblong, 

 varying from 4 or 5, to 7 or 8-flowered. Glumes lanceolate. Outer 

 palea very acute, and even slightly awned ; though never so promi- 

 nently as in Triticum caninum, the awn scarcely exceeding half its 

 whole length. The pest of cultivation, being most difficult to ex- 

 tirpate, by reason of the excessive brittleness of the numerously- 

 jointed and creeping underground stems.
