Castilleja latifolia |
| Can be sufficiently separated from other Castilleja species in Washington by the combination of perennial habit, yellowish inflorescences, acute calyx tips with median clefts deeper than the lateral clefts, greenish corolla enclosed by the calyx (or nearly so), and close association with sagebrush. See also Castilleja cervina. |
