The herbage is ashy gray-green, gray, or whitish due to a layer of white woolly hairs.
[6] Most of the local territory has converted to brushland dominated by cenizo (Leucophyllum frutescens) blackbrush (Coleogyne ramosissima), and creosote bush (Larrea tridentata).
Other dominant plant species include mesquite (Prosopis glandulosa), goatbush (Castela texana), anacahuita (Cordia boissieri), and javelina brush (Microrhamnus ericoides).
Grazing is not a direct threat because cattle do not eat the foul-smelling plant, but their trampling may compact the soil.
The introduction of buffelgrass for better grazing has led to drastic changes in the plant community, because it spreads and competes easily with other species.
