Stems running to a great height in the bushes, where it grows, and spreading widely, 

 so as to choke its supporters. Leaves of six or nine pair of leafets, mostly alternate. Sti- 

 pulae in pairs, small, deeply divided into several awl-shaped segments. Flowers whitish, 

 with beautiful pencil-streaks of blue. Pods lanceolate, smooth, pale brown. E. Bot. t. 79 •

The habits of this Vetch are similar to those of the Vicia cracca, but it seems more impatient

situations, the produce is inconsiderable, compared to that of the Vicia cracca, or Vicia scepium; 

 though in its natural place of growth the produce is six times that of either of these Vetches, it is 

 likewise superior in the quantity of nutritive matter it affords. Horses, cows, sheep, and the 

 South American sheep, (lamala), ate this Vetch with more eagerness than they did the other 

 Vetches or natural grasses that were on several trials offered to them. 



Of all the different Vetches that were submitted to experiment, the Winter Tare, or Common 

 fVicia sativa, var.) 



cut at the 



time of flowering, afforded 4 dr. 4 gr. of nutritive matter ; Spring Tares afforded only 3 dr. 5 qrs. 

 ^vhich confirms the justice of that preference which practice has given to the former. 

 Flowers in July and August, and the seed is ripe in September.
