Hastingsia alba
Hastingsia serpentinicola
At high elevations, Hastingsia alba is often stunted and has smaller bulbs, shorter scapes with shorter and narrower leaves, and spreading-rotate tepal tips.

Hastingsia serpentinicola grows in open sites that are moist in the early spring and dry out rapidly in the summer. It often occurs along the edges of Darlingtonia bogs or on the drier islands within the bog environment. At high elevations, it occurs on exposed serpentine ridges, usually close to wet habitats.
