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).

yes
a source of a potent mitogen… esp immune enhancer and some claimed inhibitor of aids viral replication… those interested google “pokeweed mitogen” the pokeweed lectin… and look for immunology journals.. ps was considered to be teratogenic for handlers of this plant parts when large amounts were collected for analysis etc… i think purdue folks had some write ups if i am not mistaken… Learnt from the net about Indian Pokeweed (Veratrum viride Aiton)…though never seen in the field. Requesting … to kindly enlighten if Indian and American Pokeweeds resemble somehow in their bio-activity. I have never heard Veratrum sp called Indian Pokeweed… its a lily family member called Hellebore… native americans/ tribals used to treat high blood pressure with it.. but the therapy is apparently fraught with dangers and given up… (( so called Indian pokeweed is also a north american plant, a lily family, very different, very toxic…why is it called pokeweed I am not sure, ) …livestock is known to die from foraging on the green new shoots of this lily plant… its very toxic… This lily grows in water logged soil, mostly in American northwest states .. Phytolacca acinosa is much relished pot herb that Dr Srivastava my associate and author of a paper on this plant used to get from sunday market .It will be interesting if P.americanaa is also edible. No … its not … could tell us about this paper, or do you have a copy? Flowers of the Himalaya by Pollunin & Stainton p341clearly mentions Phytolacca acinosa Roxb. as an excellent pot herb if leaves are well boiled.. A photograph is also given.The plant was procured from sunday market at Gangtok and much relished by myself and Dr Srvastava,now a Jt Director in BSI.He prepared a paper for Jl Hill Research by Sikkim Society in 1990. As I left Sikkim for CAL I have nt received reprintsts,I talked about less-known edible plants -Madurai Science Congress Botany section unde Prof Purakayastha. ..
thank you… I never knew about the toxicity of broccoli…just googled it and found some cases but unfortunately no authentic links. Would you plz suggest some authentic readings to know more about the same? I am interested as broccoli is one of my favorite vegetables! Broccoli? Mine too, love it, sauteed with onions and in snowy winter day with garlic…otherwise not… Googled ‘Glucosinolates & Broccoli’ and found a number of papers! Had a fast look on few of them and learnt about glucosinolates which are supposed to be good anti-carcinogenics. Interesting!!
Attaching three PDFs for your perusal. Hope to learn something more from you.

efi page on Phytolacca acinosa (altitude in Flora of China does not match) & Phytolacca americana
Species list in Flora of China Yes, I was also wondering about the altitude! I think matches with images at various threads under Phytolacca Americana

yes it is. had not followed its distribution in asia. seems it may have even naturalised in parts of asia ! certainly a danger to children who think the ripe bluish-black berries look inviting. but it soon burns their mouths, and saves any fatal high dose intake.
pokeweed mitogen is potent lectin the modulates immune response. commercially isolated in large scale.
we had long conversation there. if interested one could always look it up.

I think P. americana: flowers spaced, stamens 10-12 in number In P. octandra flowers are condensed and stamens 8-10
