Habitat

It is found on alkaline soils of wet saltgrass meadows, springs, and seeps that are restricted to Ash Meadows National Wildlife Refuge. Water availability is a limiting factor to the species distribution (Pavlik and Manning, 1986).

Ecological Relationships

Two bee species were observed visiting C. namophilum, but buds are capable of producing mature seed with pollinator exclusion (Biowest, 2009a and 2009b). Seeds may be dispersed by small animals, wind, and water.
