a rudimentary neuter oue. Glumes 2, collateral, awned. Glu- 
mellas 2, outer one awned covering and adhering to the caryop- 
sis. — Name of dubious origin. 
* Lateral spikelets perfect, middle ones usually neuter (or imperfect'). 
1. H. sylvaticum Huds. (Lyme-grass, or Wood B.) \ all the 
glumes setaceous and scabrous (not ciliate), outer glumella of

Woods and thickets, especially in a chalky soil, apparently not

** Lateral spikelets neuter, middle one perfect. 
2. IT. pretense Iluds. ( Meadow B.) ; all the glumes setaceous 
and scabrous (not ciliate), outer glumella of the middle spike- 
lets about as long as its awn, of the lateral ones with a short 
awn. E. B. t. 409: Pam. Gr. t. 11. 
Moist meadows and pastures in England, frequent ; rare in Scot-

Waste grounds, by walls and road-sides ; common in England ;

Light dry pastures and sandy ground near the sea, not rare in Eng- 
land. ©. 6. — All our British grasses of this genus are admirably 
characterized by the form, & c., of their plumes. The present is the 
smallest species, procumbent at the base and glaucous. 
37. Triticum Linn. Wheat. Wheat-grass. (Tab. VIII. f. 34.) 
Spikelets solitary, transverse (the sides, not the backs, of

flowered. Glumes 2, opposite, nearly equal, both with 3 or 
more nerves or ribs. Glumellas 2; outer one lanceolate, acumi-
