12. Lespedeza acuticarpa n. sp. 

 PI. III. f. 1, 2. 



Erect or suberect perennial, 2.5-5 dm. tall, not bushy- 

 branched, but growing in clumps ; branches erect-ascending ; 

 stems in same plant varying from nearly glabrate to woolly- 

 hairy ; leaflets 8-28 mm. long, 4-8 mm. wide, oblong-elliptic, 

 glabrate above, appressed-pubescent beneath ; petiolules 1 mm. 

 long, villous; leaf-rachis (2-6 mm. long) and petiole (2-20 

 mm. long) appressed-pubescent; stipules subulate; flowers 

 in short few-flowered (6 or less) spikes, on peduncles 1-4 

 mm. long, the inflorescences much exceeding the leaves ; 

 flower pedicels 2-4 mm. long ; flowers purplish, 6-8 mm. long, 

 the keel somewhat exceeding the wings; calyx 2 mm. long, 

 its long subulate teeth 3 mm. long, short appressed-pubescent; 

 pod 6 mm. long, distinctly short-stiped, subglabrate or spar- 

 ingly pubescent, ovate, twice the length of the sepals, strongly 

 acute or almost acuminate, usually tipped by the long per- 

 sistent style ; non-petalif erous flowers sessile. 



Not very common in open post oak woods and limestone 

 barrens. Distinguished from L. Nuttallii Darl. by its nar- 

 rower leaves, fewer flowers, and large acuminate, less hairy 

 pod. L. Manniana differs in its very long hairy sepals, and 

 nearly included scarcely pointed pod.
