All these plants are called Pea-Vines or 

 Binders, and are much relished by cattle. 

 They entwine over plants and shrubs, in woods 

 and among rocks. All in my Autikon. Their 

 blossoms are estival.

 hispid, hairs adpressed, folioles equal ovate a- 

 cute, glaucous and retieulate beneath : pedun- 

 cles filiform I-3flore, bracts ovate lanceolate, 

 calyx smooth, pods pubescent Ohio, Illinois 

 &.c : flowers minute monoical or dioical, com- 

 monly apetalous, sterile sessile, but fertile and 

 pods with pedicels.

 Amphic. do Elliot .... Twining glabrous, fo- 

 lioles ovate acute, peduncles filiform triflore, 

 calix villose, pods smooth Carolina, flowers all

 spreading, twining stem, folioles elliptical ob- 

 tuse or retuse, cuspidate glaucous, some ovate 

 or rounded : flowers sessile, calix hirsute, pods 



sessie geminate pubescent In Kentucky &c,

 2-3axiIiary sessile. 



10. LOB. MONTANUM Raf. Glycine montana 

 Raf. atl. Journ. Dioical, smooth, stem erect 

 flexuose, folioles ovate acute ; peduncles uni- 

 flore, pods and calix smooth On the rocks of 

 high hills in the Alleghanies of Pennsylvania, 

 Juniata and Sherman Valleys. Only semipe- 

 dal and root annual. 



The fecondation- of these plants is a problem, 

 and their apetalous structure a great anomaly. 

 All in Autikon except 8. They form a pecu- 

 liar group TETRODES Raf. by their curious ano- 

 malies, with Amphicarpa and the 2 next fore- 

 ign plants.
