Castilleja tenuiflora

Synonym: Castilleja laxa

Family: Scrophulariaceae

Distribution: Southeastern Arizona south throughout most of Mexico to the Sierra Madre del Sur of Guererro and Oaxaca. In NM, it occurs in the mountains from the Animas to the Datils.

Habitat: Mountains and higher hills from moderately dry chaparral to the mesic pine forests.

Discussion: Holmgren (1976) states this is the most common, most widespread, and perhaps the most complex species in Mexico. This is not a rare species.
