Appending the usual message to Florida plant ecologists that this is Harrisia aboriginum (IUCN EN) and that if you're interested in using this specimen or materials from it for the purpose of reintroduction, please get in touch!
@thebiologistisn •Two Harrisia aboriginum grown from seed (seller listed them as a nonexistent species). •Rhipsalis pilocarpa (I have no excuse, I'm frivolous) •Vanilla dilloniana (had NO idea they were vulnerable in the wild) •Lophophora williamsii (though I bought the seeds reputably)
