Keys at Flora of North America
Inkweed (Phytolacca octandra) is very similar to American pokeweed (Phytolacca americana) and Venezuelan pokeweed (Phytolacca rivinoides). These species can be distinguished by the following differences:
-Inkweed (Phytolacca octandra) flowers are borne on very short stalks (i.e. pedicels) only 2-3 mm long and usually have 7-8 stamens. Their ‘petals’ (i.e. tepals or perianth segments) turn red and persist on the developing fruit. The mature fruit are relatively small (4-6 mm across) and usually have eight slight lobes (i.e. they usually contain eight seeds).
-American pokeweed (Phytolacca americana) flowers are borne on relatively long stalks (i.e. pedicels) 5-10 mm long and usually have 10-11 stamens. Their ‘petals’ (i.e. tepals or perianth segments) turn red and persist on the developing fruit. The mature fruit are relatively large (5-11 mm across) and have ten or eleven slight lobes (i.e. they contain ten or eleven seeds).
-Venezuelan pokeweed (Phytolacca rivinoides) flowers are borne on relatively long stalks (i.e. pedicels) 7-12 mm long and have 9-14 stamens. Their ‘petals’ (i.e. tepals or perianth segments) fall off as the fruit begin to mature. The mature fruit are relatively small (5-6 mm across) and have 12-16 slight lobes (i.e. they contain 12-16 seeds).

If you find any incorrect identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, or can identify unidentified images, it will be really nice.
