A procedure for standardizing comparative leaf anatomy in the Poaceae. II. The epidermis as seen in surface view

Descriptive “keys”, including definitions and explanatory diagrams, are given for the standardization and simplification of anatomical descriptions of the epidermides of grass leaf blades as seen in surface view. About 340 characters of the epidermis are included with ample room for expansion. Notes on variation and taxonomic importance of the characters are also included.
