This plant is near to Pentstemon erianthera, but differs from that, and from the other species with which I am acquainted, by the glutinous pubescence of the flowers. These are wide, infundibuliform, and seem to have been of a dark red colour. My specimen is about a span high. This species has, perhaps, been already described among species of Pentstemon recently made known; I have not, however, been able to find any corresponding with it where I looked for it.
