UPDATES FOR AUTHORS Contributing to the Second Edition of The Jepson Manual and to the Jepson Flora Project

Glossary Update

The following changes have been made to the Glossary in the Guide for Authors Contributing to the Second Edition of The Jepson Manual and to the Jepson Flora Project, as a result of discussions involving Baldwin, Keil, Morefield, and Strother about terms and definitions to be used for Asteraceae in TJM2. Some of the changes involve more widely applicable terms.

1. "ligulate" replaced with "liguliflorous" as applied to heads
