Apocynaceae wood evolution matches key morphological innovations.

ABSTRACT:

Premise

This paper provides an overview of the wood anatomy of the dogbane family (Apocynaceae), reconstructs wood anatomical trait evolution, and links this evolution with woody growth-form transitions and floral and seed trait innovations across the family.

Methods

Over 200 published wood anatomical descriptions were revised, and original light microscopic sections were made and described for another 50 species. Changes in wood anatomical characters through time were visualized with ancestral state reconstructions. Tests for correlated evolution were performed using a combined data set of anatomical and key floral and seed traits to identify potential synnovations and traits associated with growth-form adaptations.

Results

There was a shift toward a suite of wood an
