G. AMPHICARPA. 83 



4. Amph. Ellioti Raf. monoica Elliot. G/. 

 monoica ? L, stem twining angular with reflex- 

 ed hairs, folioles ovate lanceolate subequal,thin, 

 acute^ scabrous above, petiols long: racemes 

 pendulous commonly sterile, calix hairy gib- 

 bose. Pods of imperfect flowers ovate one seed- 

 ed — In Carolina, Virginia &,c. Flowers white 

 and violet. Doubtful sp. yet, since Elliot says 

 in diagnosis learns glabrous^ and in description 

 hairy ! He confirms the existence of imperfect 

 flowers in racemes, cultivated for these pods 

 like Arachis, but Linneus says these subterra- 

 nean flowers are solitary ! It would be hard to 

 say what Michaux, Pursh, Torrey, Hooker, 

 Beck, Eaton &c mean by their monoica, which 

 they do not describe, blending 4 or 5 sp. under 

 that false name j most of them have all the 

 flowers perfect and fertile. 



5. Amph. deltifolia Raf. stem twining with 

 reflexed hairs, petiols short, folioles scabrous 

 ciliate ovate deltoid, lateral obliqual, medial 

 rhomboidal : racemes short equal to petiols, 

 ere€t pauciflore, bracks ovate acute striate — 

 From Canada and Missouri to New Jersey, the 

 most common kind and probably the monoica 

 of many botanists, but without imperfect flow- 

 ers ; all with whitish petals, although many are 

 abortive several Var. 1, Incarnata, 2 procera 8 

 feet high &c. 



6. Amph. cuspidata Raf. stem twining an- 

 gular hairy, hairs patent fulvous, petiols very 

 long, folioles ample ovate cuspidate nearly 

 smooth, lateral obliqual : racemes elongate ra- 

 mose, racemules 3-4flore, bracts ovate obtuse 

 striate, equal to pedicels, Calix smooth — 3Its. 

 Cumberland of East Kentucky, disc. 1823. 

 Leaves large 3-4 inches, petiols 6-8 inches : 

 flowers small, white.
