Description

Stem leaves are alternate, lobed, and hairy, with no basal rosette. Upper leaves are deeply lobed, becoming purple-tipped floral bracts. Sepals form a five-lobed calyx, with petals forming two-lipped flowers measuring 10-18mm in length. Lower calyx lips are yellow with white tips, and upper lips are a creamy white. Fruits are brown capsules with two cells that split when ripe to reveal 30-70 seeds. [6] [7]

Habitat

Castilleja victoriae is found exclusively in vernal pools and seeps associated with Garry oak ecosystems within 50 metres of the coast. [5] Four of its historical occurrences have been extirpated since the turn of the last century due to habitat loss and degradation. [8]
