Christine’s Grevillea

Christine's grevillea (Grevillea christineae) is a flowering shrub in the family Proteaceae, endemic to Western Australia. Grevillea is one of the largest genera in Proteaceae, with over 350 species distributed primarily across Australia. Christine's grevillea, like many members of this diverse genus, is adapted to the nutrient-poor soils and dry, fire-prone landscapes of southwestern Australia, one of the world's recognized biodiversity hotspots. Grevillea species typically produce distinctive spider flower or toothbrush-style inflorescences rich in nectar, making them important resources for honeyeaters, lorikeets, and other nectarivorous birds and insects. The genus exhibits remarkable diversity in flower color, leaf shape, and growth form, ranging from low ground covers to small trees. Christine's grevillea is a limited-range endemic, and like many narrow-range Western Australian species, it faces potential threats from habitat clearing, altered fire regimes, and invasive species such as Phytophthora cinnamomi, a water mold that devastates Proteaceae-dominated vegetation. Western Australia's Banksia woodlands and kwongan heathlands support extraordinary concentrations of endemic plant life, and the conservation of such habitats is critical for species like Christine's grevillea. The species has not been widely assessed but warrants monitoring given its restricted distribution.
