the length of the stems in the typical plant. The stems are slightly furrowed at the base, 

 higher up more deeply striate, sparingly pubescent, or sometimes nearly glabrous, with 

 rather approximate leaves. The leaves are sessile, 4 — 5 cm. long, generally 7-pinnate, 

 only rarely to 11-pinnate. There is a marked difference between the leaves in the lower 

 and upper parts of the plant. Thus, the leaflets in the lowest leaves are broader, ovate or 

 oval, 3—5 mm. broad, one and a half to twice as long, slightly emarginate or subobtuse at 

 the apex. In the upper leaves, the leaflets become gradually narrower, only 1—2 mm. 



broad, 4—10 times as long. The greatest 

 length of the leaflets does not exced 15 mm. 

 Their shape is linear to broadly linear, rather 

 equally broad throughout their length, obtu- 

 sely rounded at the apex, truncate, or rarely 

 slightly emarginate. The leaflets have short 

 stalks, 0,5 — 1 mm. long. The upper side of 

 the leaves is generally glabrous or only very 

 slightly hairy, the under side always slightly 

 hairy, especially so along the midvein. The 

 stipules are small, 2 — 3 mm. long, triangular, 

 glabrous or slightly ciliate, quite detached, 

 by no means adnate to the petiole. The 

 raceme is very long-peduncled, rigid and 

 straight, but thin and tender, 5 — 10 cm. long, 

 about twice exceeding the axillary leaf, loose- 

 ly flowered, generally 7- to 10-flowered, only 

 rarely with to 14 — 15 flowers, especially the 

 lower ones, rather distant. The bracts are 

 small, 1 — 2 mm. long, of about the same 

 length as the pedicels, membranous, or of a 

 pale green, subulate and acutish, sparing- 

 ly pubescent and ciliate, frequently with a 

 tuft of black or white hairs at the apex. The 

 pedicels 1 — 2 mm. long, sparingly pubescent. 

 The calyx is about Va of the length of the 

 corolla, beset with scattered black and white 

 hairs, divided above into 5 narrow, equal 

 teeth. The corolla is 8—10 mm. long, of a 

 hght violet or lilac. The standard is nearly 

 ovate, 8—10 mm. long, slightly emarginate.
