|phenology=Flowering Apr–Jun(–Jul).
|habitat=Seasonally wet meadows with volcanic substrates in oak-pine woodlands or chaparral, shallow vernal pools, ephemeral stream margins.
|elevation=400–500 m.
|distribution=Calif.
|discussion=<p>Variety meadii is limited to vernally wet habitats, growing over rocks of the Sonoma Volcanic Formation in central Napa County near Atlas Peak. All known populations are under private ownership, and the variety is of conservation concern due to its very limited range. For the present, all populations except one are protected by conservation easements. Variety meadii often grows alongside, but does not hybridize with, <i>Castilleja attenuata</i> and <i>C. densiflora</i>. Ongoing study of annual species of <i>Castilleja</i> suggests this variety is genetically distinctive and may deserve full species status (S. J. Jacobs et al. 2018).</p>
