996 VICIA. [CLASS XVII. ORDER 111. 
peduncles, shorter than the leaves, angular, hairy, terminating in a 
raceme of from four to ten small pale blue flowers, turned to one side. 
Calyx tubular, its teeth cut into slender lanceolate teeth, as long as 
the tube. Corolla white or blueish, the vexillum ovate, entire, the 
keel obtuse, mostly with a dark spot on each side. Legume ovate 
oblong, oblique, two seeded, downy. 
Habitat.—Corn fields and hedges; very common. 
Annual: flowering from June to August. 
This is a very troublesome weed in corn fields, especially on a light 
sandy soil, and is equally as common on the Continent as with us. 
4. V. tetrasp'erma, Koch. (Fig. 1157.) Smooth Tare. Peduncles 
one or two flowered; petioles terminating in a branched tendril, 
bearing about eight pairs of linear oblong obtuse leaflets ; stipules 
half arrow-shaped, with linear lanceolate lobes; legumes linear

Root small, tapering, the whole plant scattered over with fine soft 
pubescence. Stem angular, branched, weak, climbing, spreading, 
from two to three feet high. Leaves numerous, the petioles chan 
neled, tapering, terminating in a branched tendril, and bearing about 
eight pairs of linear oblong obtuse leaflets, paler on the under side, 
the mid-rib terminating in a short point. Stipules half arrow-shaped, 
ihe lobes narrow, linear lanceolate. Inflorescence slender axillary 
peduncles, shorter than the leaves, and bearing one or two small pale 
blue flowers. Calyx tubular, unequally fine toothed. Legume 
linear oblong, smooth, four or five seeded, sometimes more or less. 
Habitat—Moist corn fields, under hedges, &c.; frequent. 
Annual; flowering in June. 
We have followed Koch in placing these two species with the 
Vicia, (rather than the genus Hrvum), with which in their generic 
character they agree much more than with Ervum. 
sack Peduncles elongated, single flowered.

half arrow-shaped, toothed ; peduncles more or less elongated, one or 
two flowered ; teeth of the calyx linear lanceolate, as long as the 
tube ; legume erect, compressed, linear oblong, downy.
