NEW AND RECONSIDERED MEXICAN ACANTHACEAE. VII

Abstract

Dyschoriste novogaliciana is described
and illustrated. It is known from four states
in western Mexico, and has been collected
numerous times in the Nueva Galicia region.
A key to all species of Dyschoriste in the
Nueva Galicia region of west-central Mexico
is provided. Ruellia leucantha var.
postinsularis is elevated to the rank of
subspecies. It differs from R. leucantha
subsp. leucantha from Baja California Sur
by minor morphological features (shorter
trichomes and capsules) that have a
geographic basis. The name Ruellia
candida is treated as a synonym of Ruellia
leucantha subsp. postinsularis.
