Distribution and range
editCastilleja victoriae is endemic to a small region of southeastern Vancouver Island in British Columbia (near its namesake city of Victoria) and a single site in the San Juan Islands of Washington State. There are four or less extant populations in existence.[5]
Description
editStem 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
editCastilleja 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]
