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. 
7. Lobomon acutifolium Raf. Twining quite 
hispid, hairs adpressed, folioles equal ovate a- 
cute, glaucous and reticulate 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. 
8. Lobo sarmentosum Raf. Glycine do W* 
Amphic . do Elliot .... Twining glabrous, fo- 
lioles ovate acute, peduncles filiform triflore, 
calix villose, pods smooth — Carolina, flowers all 
apetalous and seeds grey, Spotted with black. 
9. Lob. obtusifolium Raf. Pilose, hairs 
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, 
monoical, flowers apetalous, upper ones sterile, 
2-3axillary 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 A mphicarpa and the 2 next for^ 
ign plants.
