Hedeoma costata var. pulchella (Greene) R.S.Irving
EOL Text
Global Range: Hedeoma costata var. pulchella ranges from the desert mountains of the southwestern U.S. (Arizona, New Mexico and Texas) south to Chihuahua, Coahuila, Nuevo Le?n and Zacatecas in Mexico (Irving, 1980).
Comments: Hedeoma costata var. pulchella occurs in a broad spectrum of desertic habitats, from colluvial fans in desert scrub at lower elevations (400-750 m) to pine woodlands at higher elevations (2000 m). Substrates are mostly derived from limestone (Henrickson and Johnston, A flora of the Chihuahuan Desert region, in preparation).
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 81 to >300
Comments: Hedeoma costata var. pulchella ranges from the southwestern U.S. to northern Mexico and occupies a broad spectrum of habitats. Although no occurrence information has been collected, well over 100 occurrences can be expected.

Rounded National Status Rank: NNR - Unranked
Rounded Global Status Rank: T4 - Apparently Secure
Reasons: Hedeoma costata var. pulchella (Greene) Irving occupies a wide variety of nondescript habitats across a global range from the southwestern United States to Zacatecas, Mexico. Although no occurrence information is available, hundreds if not thousands of populations can be expected.
Comments: Threats to Hedeoma costata var. pulchella are unknown and, when compared to globally rare plants of the region, relatively non-existent or at best very local. The taxon is globally widespread and occupies a broad spectrum of habitats, and it is hard to imagine a suite of serial or simultaneous threats that could adversely effect the taxon throughout its range.
Comments: Name spelled 'pulchellum' in some floras. The other variety of the species, Hedeoma costata Gray var. costata, is restricted to the Sierra Madre Oriental in eastern Mexico (Irving, 1980).
