Ok Artijiciat Grasses. 



solitary, footstalkctl, equalling the leaf, and sometimes exceeding it, oval or 

 elliptic, obtuse, toothed, many-flowered. Foot-stalks principally villose at the 

 tip. Cdycine teeth subulate, unequrd, hairy. Corol gold-coloured. Flowers im- 

 bricated, at length deflected, with the corol permanent, scariose, dusky, and the 

 standard longitudinally furrowed, inflected, dilated, and nearly obcordate. Le- 

 gume elliptic, sharp on both sides, single-seeded^ 



The flowers, which are yellow, grow from the wings of the stalks, upon long 

 foot-stalks, collected into oval, imbricated heads, having naked empalements, 

 lying over each other like scales, somewhat like the flowers of hops, "from whence 

 this plant took the name of hop clover. 



This plant is not very productive, and thrives best upon dryish gravelly 

 fields, and pastures. 

 VI. 1. ViciA Sativa. Common, Purple Flowered Summer Vetch, or Tare^ 

 2. ViciA Lathyroides. Purple Flowered Wild Vetch, or Winter Tare. 



The most proper soil for these tares, is a barren sandy soil; next to it, are, 

 gravelly, chalky, and limestone soils; but they will thrive in most kinds, except 

 strong moist clayey, or cold moory soils. 



\. Of the Summer Vetch, or Tare. 



Vetch with sessile subbinate suberect legumes, lower leaves retuse, toothed 

 stipules marked by a spot, and smooth seeds* 



Annual, flowering in May and June. 



Stems various in size, either climbing or prostrate. Plant more or less pu- 

 bescent. Leaves three or many-winged, with an elongated tendril either two or 

 three-cleft, and opposite or alternate leaflets, which are rather sharp-pointed, of- 

 ten retuse, and of various width. Stipules semisagittate, more or less toothed, and 

 marked on the outside by a black or pale impressed spot. Flowers axillary, solita- 

 ry or binate, subsessile, varied with purple. Legume somewhat compressed, brown, 

 rough. Seeds numerous, a litte compressed, very smooth.
