The above characters are common to all the specimens I have 
seen, extending from Florida to Canada, those of more southern 
growth being naturally larger and more luxuriant. The inter- 
nodes are 4 inches long; the leaves 3|-5 inches long, 3|-5^ inches 
broad, on a petiole 3-4 inches long. The flowers have 6 se- 
pals, 6 petals, 15-16-18 stamens ; ? 6 sepals, 6 petals, 6 sterile 
stamens, and 3 ovaries ; the putamen is 3^ lines in diam. The 
Menispermum Smilacinum, DC., seems to differ in having only 
4 petals.
