South Wales Galloway, Scotland. If.. 6 — 8. — Stem 2 — 3 ft. high,

- — The stifle of this plant is as in Lathyrus, to which Bigelow has re- 
moved it. The rar. j3., brought by Dr. M‘Nab from Shetland in 1837, 
in its slender straggling habit and narrow leaves comes very near the 
L. Altaicus Ledeb., but that has much smaller stipules and cylindrical 
legumes. The same form is found in Iceland and Arctic America.

place of tendrils, both structures being morphologically the same, we
