A species with the leaf-form of R. simphicifolia, but the habit 
of R. menispermoidea. It has passed under the above names and 
also under that of R. tomentosa var. volubilis, but is very distinct 
from all forms of the type of the latter species. The lateral leaflets 
of R. tomentosa are always acutish, those of R.Michauxi being ob- 
tuse and rounded. The leaves are largerthan those of A. menis- 
permoidea, less conspicuously veined, and apparently never cordate, 
the flowers more numerous, the calyx larger and more distinctly 
foliaceous.
