The arid south-western United States contains a very large number of species of Penstemon and is one of the important centers for the distribution of this scrophulariaceous genus.The present paper deals with some of the showiest members of the entire genus, and, accordingly, several of these have received attention from the horticulturists. This section of Penstemon has received no treatment as a whole since the appearance of Gray's 'Synoptical Flora' over half a century ago, and as the intervening years have disclosed quantities of new facts, the present revision offers a new alignment of the systematic elements.
