# Areca catechu

Arecaceae. 2 equations apply. Each output lists them most specific first: fitted on this species, on a variety of it, pooled fits that included it, then its genus and family. Within each step, equations the authors advised against go last, then those read from compilations; more trees come first. The order shows how specific the evidence is, not which equation predicts best.

## General equations that may apply

Fitted on many species across the tropics or the world, so not ranked against the ones above.
