Just b.caapi and p.viridis.
Those are kosher to post here! We have entire megathreads dedicated to propagating and growing those Sacred Plant Teachers; it's common to see posts brimming with shots of caapi and PV (and/or P. Nexus, or any other psychotria for that matter of a fact).
I do not know which country you inhabit, but in my locale--FL, USA--these plants are completely licit so as long as they are not consumed, nor prepared for human consumption in any way/shape/form, and are grown for ornamental purposes
Our community loves these Plant Teachers. So as long as your posts containing pics of these do not involve any allusion to consuming them or preparing them for human consumption, you're in the clear. For all Big Brother knows, you'd just be a little fishy showing off some glamour shots of your prized plants on STS for any purpose sans anything related to human consumption or preparation for consumption (please remember that no one here wants a surprise 4 AM visit from their local SWAT team, and we wanna keep the heat down to luke warm at the very most, and absolute zero at the very best).
I am eager to see your PV and Caapi collection; don't think twice, it's alright.
Keep it Koshah,
Mangrove
TL;DR it's ok to post pictures of P. Viridis and B. Caapi on STS.
