>— 7. V. Caroliniana (Walt.) : stem branrhin?; loaHcts 8-12, lincar-oblonjj, 

 nearly glabrous, rather obtuse, scarcely rnucroiiate ; stipules lanceolate, mi- 

 nute; peduncles many-flowered ; racemes rather loose; teeth of the ralyx 

 shorter than the tube, the upper ones very short; style hairy at the summit; 

 letjuiue oblong, coriaceous, not reticulated ; seeds subglobose, blackish. —

0. ? Te.j-anii : very slender; leailets S-10, nearly linear; stipules unequal- 

 ly bifid at the base; peduncles 6-10-ilowered, longer than the leaves ; flowers 

 crowded. 



Borders of woods and banks of rivers, Canada! to Georgia ! west to Ken- 

 tucky ! April-May. — U Stem 3-6 or 8 feet long, slender, climbing. Leaf- 

 lets usually scattered, 6-10 lines long. Racemes 6-15-llowered ; the flowers 

 Avhite, or pale blue, with the top of the keel deep blue, commonly smaller 

 than in the preceding species, and more loosely arranged on the peduncle. — 

 The most certain distinguishing character is found in the shorter and broader 

 teeth of the calyx of this species. The Texan variety may prove to be dis- 

 tinct ; but we have not seen the legumes. 



-/-8. V. Ludoviciana (Nutt, mss.): glabrous (except the young shoots); 

 leaflets 10-12, elliptical or obovate, obtuse or emarginate; stipules subulate, 

 simple or semisagittate ; peduncle 2-6-flowered, at hngth longer than the 

 leaves ; flowers (minute) closely approximated ; teeth of the calyx broad, acu- 

 minate, shorter than the tube ; legume broadly sabre-shaped, glabrous, 5-6- 

 seeded ; seeds compressed, dark brown. 



Grassy places on the Red River, and in Texas, Dr. T^eax-enworth! "In 

 Louisiana, Mr. Tainlnrier,'''' Nutt all. May. — U Stem 2-3 feet long, rather 

 stout, strongly angled, climbing. Leaflets 6-S lines long, 2 lines wide, com- 

 monly emarginate. Stipules very small. Flowers blue, smaller than in V. 

 Cracca, rarely solitary, often 2-6 on a peduncle. Calyx hairy. Keel marked 

 Avith a deep blue spot at the summit. Legume J of an inch long and 3 lines 

 wide. — Mr. Nuttall in his manuscript describes the peduncles as i-2-flovvered, 

 Avhich is the case in some of our specimens ; but the peduncles are more com- 

 monly at least 4-flowered. 



9. V. Learenu-orthii: pubescent; leaflets 10-14, oblong-linear, obtuse or 

 emarginate; stipules minute, semisagittate, entire; peduncles shorter than 

 the leaves, 2-4-rtowered (flowers minute) ; teeth of the calyx subulate, some- 

 Avhat equal, all longer than the tube; style slightly pubescent at the summit; 

 legume oblong, 6-seeded. 



Arkansas, Dr. Leavenworth ! — If ? Stem 1-2 feet long, strongly angled. 

 Leaflets approximated, half an inch long and li line wide. Flowers as 

 large as in V. tetrasperma, pale blue ? — Resembles the last two species, but 

 is easily distinguished by the long and narrow teeth of the calyx. 



10. V. micrantha (Nutt.! mss.): glabrous ; leaflets 4-7, linear, obtuse or 

 acute ; stipules lanceolate, semisagittate ; peduncles shorter than the leaves, 

 1-2-flowered (flowers minute); teeth of the calyx lanceolate, shorter than 

 the tube ; legume sabre-shaped, 7-10-seeded. 



Prairies and woods of Arkansas, Nuttall! Louisiana and Texas, Dr. 

 Learenworth! on the Red River, Dr. Hale ! April-May .^(5)1 Stem 

 slender, 2-3 feet long. Leaflets about an inch long; in the lower leaves trun- 

 cate and often toothed at the summit. Flowers as large as in the preceding 

 species (pale blue?) ; the peduncles at first scarcely one-third the length of the 

 leaves. Style very short. Legumes an inch in length, slightly pubescent. 

 Seeds blackish, compressed ; the hilum extending 1 of its circumference, 



J— 11. V. acutifolia (Ell.): glabrous ; leaflets 3-6, linear, usually acute ; sti- 

 pules linear-lanceolate, semisagittate, entire ; racemes longer than the leaves,
