112 ENGLISH BOTANY. 
Rootstock short, without tubers or stolons. Stem erect, 
branched, angular, but not winged. Leaves with 4 to 6 pairs of 
broadly elliptical or oblong mucronate leaflets; common petiole 
terminating in a setaceous point. Stipules small, linear-lanceolate, 
half-sagittate or hastate-sagittate at the base, with a small acute 
auricle. Peduncles equalling or exceeding the leaves, 3- to 8-flow- 
ered. Flowers drooping, in a rather lax raceme. 3 lower calyx- 
teeth deltoid-triangular, not half the length of the tube; the upper 
pair much shorter. Corolla three times as long as the calyx. 
Pods linear, sub-cylindrical, slightly compressed. Seeds quadrate, 
compressed, smooth ; hilum about one-fourth the circumference of 
the seed. 
In rocky copses in mountainous districts. Very rare. In the 
Den of Airly, twelve miles west of Forfar; and in the Pass of 
Killicrankie, Perthshire; also said to occur on Craiganain, a rock 
within two miles of Moy House, Inverness-shire. 
Scotland. Perennial. Summer. 
Stem slender, almost wiry, erect, 1 to 2 feet high. Leaflets 
+ to 14 inch long, usually lanceolate-elliptical, but variable in 
breadth, though not nearly to the same extent as in the last species. 
Stipules of the lower leaves 3 inch long; those of the upper very 
minute. Peduncles 2 to 4, inches long. Flowers 4 inch long, with 
the claw of the petals longer than the lamina, dull purplish-crimson 
fading to livid blue. Pods drooping, 2 inches long, black when 
ripe. Seeds § inch across, reddish-black. Plant deep-green, gla- 
brous, always turning brownish-black when drying.

Said to have been found by Ray on the coast at Orford, 
Suffolk; but the Rev. W. W. Newbould informs me that Ray’s

Herbaria. ?
