COMMON VETCH. 



Tina sativa. Nat. Ord., Legu>ninosf. 

 HE vetch has long been cul- 

 tivated as a forage-plant, and 

 fe7 has therefore got widely dis- 

 tributed. It may be found 

 almost everywhere : on culti- 

 vated ground, on dry pastu- 

 rage, on waste patches of. soil, 

 and in open woodlands. Cul- 

 tivation has to some extent 

 modified its appearance, and 

 some two or three varieties or 

 sub-species have been recog- 

 nised, but these have a way 

 of running into each other 

 that makes their identification 

 difficult, and for our purpose, 

 at least, we need attach little 

 or no importance to them. 

 Cultivation in rich ground 

 naturally makes the plant more luxuriant in growth, the 

 stems attain to a greater height, the leaflets are broader 

 and the flowers larger ; but all these modifications are but 

 developments that can readily be traced to its change of 

 circumstances, and directly we attempt to make a specific 

 difference difficulties arise.
