pointless or with a soft point as long as the leaves 1 — 3-flowered, 
legumes 4 — 6-seeded. Ervum L. : E. B. t. 1223. — (5. leaflets 
3 — 4 pairs narrow linear acute, tendrils simple, peduncles aris- 
tate at length about twice as long as the leaves 1 — 7-flowered, 
legumes 5 — 7-seeded. Y. gracilis Lois.: E. B. S. t. 2904. 
Ervum DC. 
Cornfields, hedges, &c. — a. not uncommon in England; more 
rare in Scotland, as at St. David’s, Fifeshire; Ruthven, near Perth; 
Arbroath, and in Lanarkshire and Kirkcudbrightshire. — /3. Cobham, 
Kent; Bath; Isle of Wight. County of Kerry, Ireland. Q. 6 — 8. 
— Stipules semi-sagittate, entire. Teeth of the calyx elongated from 
a triangular base, shorter than the tube, the two upper ones diverg- 
ing. Standard of corolla in var. a. with blue streaks, in /3. usually 
without them. Seeds globose, with an oblong or oval hilum. The 
chief difference between the two vars. is in the larger flowers of var. 
i3., its narrower and fewer leaflets, the latter causing the leaves to be 
shorter than the fruit-bearing peduncle ; but there seem to be many 
intermediate forms. 
11. V. hirsuta Koch ( hairy T.) ; leaflets 6 — 8 pairs linear- 
oblong truncate, peduncles 1 — 6-flowered, legumes oblong 
2-seeded hairy. Ervum L. : E. B. t. 970. 
Corn-fields and hedges; too frequent. ©. 6 — 8. — Stems 2 — 3 ft. 
long, weak, straggling and climbing. Stipules semi-sagittate, the 
lower lobe usually cleft into several setaceous segments. ,Ftou>ers 
very insignificant, pale blue. Teeth of the calyx subulate, longer 
than the tube, the two upper converging. Seeds orbicular slightly 
compressed, with a long linear hilum. 
18. Lathtrus Linn. Yetchling. Everlasting-Pea. Bitter- vetch. 
Cal. with its mouth oblique, its upper segments shortest. 
Style flattened below the stigma, downy on the upper side.-

1. L. A'phaca L. ( yellow V.) ; peduncles single-flowered, 
tendrils without, leaves, stipules very large foliaceous cordate- 
sagittate. E. B. t. 1167. 
Borders of sandy and gravelly fields, in England, rare. Norfolk, 
Warwick, and Gloucestershire, and the counties to the south of 
these. 0. 5 — 8. — True leaves, each consisting of a single pair of 
leaflets, are rare, and only exist on this singular plant in the youngest 
state. Flowers yellow. 
2. L. Nissulia L. ( crimson V. or Grass- Vetch) ; leaflets want- 
ing but in place of them a simple linear-lanceolate sessile leaf- 
like petiole without tendrils, stipules minute subulate. E. B,
