Castilleja lineata
Castilleja integra
Castilleja lineata is restricted to the mountains of northeastern Arizona, southern Colorado, and northwestern New Mexico. It is uncommon throughout its range and is without apparent close relatives. The Navajo used C. lineata as a medicinal plant and for its sweet nectar (D. E. Moerman 1998).

Castilleja integra is widespread and common in the southwestern United States. It is important to Native Americans for dyes, ceremonies, as a food preservative, and as a medicine. It is sometimes confused with C. lanata or C. miniata but has a distinctive combination of entire, narrow, strongly involute leaves, soft-tomentose pubescence of unbranched hairs, and usually entire bracts, sometimes with one pair of short lobes from the middle. The leaf margins of C. integra are usually plane, but some populations in the Chisos Mountains of Texas are wavy margined. These plants are on the higher slopes of the Chisos Mountains in montane thorn-oak vegetation, and they are also often taller and have longer, more frequently lobed leaves. These variant populations have been called C. elongata, and they deserve further study. Castilleja integra is typically a species of dry grasslands and open forests at moderate elevations. Occasional hybrids with C. linariifolia are known from Montrose County, Colorado.
The Castilleja elongata form of C. integra is in the Center for Plant Conservation’s National Collection of Endangered Plants.
