We have a nice patch of Arisarum proboscideum and I've always thought it was a member of Arisaema, but googling is inconclusive.
Plants nerds help! :o)
They are both aroids and in the same plant family (Araceae) but other than that they are not the same and not even closely related. Each is just one of the 140 or so genera in the arum family and share certain botanical characteristics.
Arisarum proboscideum is one of my favorite plants!! So cute when in flower with the little tails sticking up in the air! Not easy to see though, and easily overlooked. I grew mine in a container placed where I could eyeball it daily when in flower.
In looking at the link I do recall seeing the word "Arum" when reading about both which led me to believe there were possibly more closely related than the they are. The flowers do have a similar textural appearance, kind of silky.
Other than wiki is there a good site where you can look up a plants family tree?

Have Arisaema sikokianum seed
Arum is a genus in that plant family as well. But it is also applied in a much broader, more generalized sense - together with aroid - to refer to all plants from that family.
I don't know if I would notice any textural similarities in the flowers right off the bat but the family shares in producing flowers with a very distinct appearance of a spadix surrounded by a spathe.
I have found the info in wiki is about as good as it gets online. More detail requires a library.
