Nice haul eric......

I knwo a bit abouyt caryota.... which im pretty sure it is ( you can tell by the trunk).

Caryota like highly organic soil in the ground. I think there might be 2 possibilities on the type: Mitis ( wish is the most likley), or Maxima. Im thinkin mabey maxima, due to the fact most mitis ive seen are bushier. They tend to have more leaves lower on the plant. The odds are, it was trimmed and is stressed to hell right now, so you wont really know till it starts growing a bit.

Inside they like bright light. High humidity and can be prone to spidermites and mealy bug. They hate being over watered, and yet dont like being dry between waterings. If you gie it enough light their really easy to take care of indoors, just watch for spidermites. I think they might be one of the plants sensitive to flouride as well.... id look that up if i were you....

Peace dude
