Picea mariana

8 equations apply to this species, 2 fitted on it directly. Each output lists them most specific first: fitted on this species, then on a variety of it, then pooled fits that included it, then its genus and its family. Within each step, equations the authors advised against go last, then those read from compilations; more trees come first.
