Abstract

Nama arizonica R.A. Crawford & G. Rink (Namaceae) is a novel Nama, restricted to Coconino and Navajo cos, northern Arizona. Previously, these plants have been determined as N. dichotoma (Ruiz & Pav.) Choisy, to which it may be most closely related, though it has morphological similarities to N. hispida as well. We present images of plants in the field, seeds, vestiture, and chromosomes.
