Rank Reasons
Species appears to be more common than once thought, numerous recent collections in New Mexico and Arizona. This species is known from less than 20 sites in three counties in Colorado and known from five counties in New Mexico. Site surveys are needed to fully understand the status of the species. The rank for this is probably G4, but this species needs more study to confirm that.
Range Extent Comments
This species is known from Colorado and New Mexico (Kartesz and BONAP 1998) and several recent herbarium specimens were collected in Arizona. In Colorado, it has been documented in Chaffee, El Paso, Fremont, and Pueblo counties. In New Mexico it is known from Catron, Cibola, Rio Arriba, Sandoval, and Santa Fe counties (pers. comm. Jane Mygatt UNM Herbarium 1999 to Kim Fayette, Colorado Natural Heritage Program). At Rocky Mountain Herbarium, specimens from NM were collected in the following counties: Taos, Rio Arriba, Sandoval, and Santa Fe. Calculations of range extent include herbarium specimens.
Occurrences Comments
There are 3 specimens from Chaffee County, Colorado ranging from 1878 to 1992 documented at the CU Herbarium (CONHP 1999) and two specimens from Pueblo and Fremont counties in Colorado at the CSU Herbarium (Colorado State University 1999). In New Mexico the species is known from collections in Catron, Cibola, Rio Arriba, Sandoval, and Santa Fe counties (pers. comm. Jane Mygatt, UNM Herbarium, 1999 to Kim Fayette). Several specimens from Arizona. There are about 67 herbarium collections made since 1995.
Threat Impact Comments
Threats documented in CO include road maintenance and herbicide spraying and mowing, ORV use, and traffic from nearby trails. Threats in New Mexico and Arizona are unknown.
Ecology & Habitat

Description

A perennial species with decumbent to erect, spreading, and much-branched stems. The ray flowers are white or pinkish, disk flowers are yellow, and the phyllaries have acute tips (Weber and Wittmann 2012, Flora of North America 1993+). The leaves of T. fendleri are usually nearly linear or sometimes narrowly oblanceolate (Ackerfield 2012).

Diagnostic Characteristics

The decumbent stems distinguish this species from others in the genus Townsendia.

Habitat

This species is found on arid hills and benches (Weber and Wittmann 1996).
