Banksia sphaerocarpa, the fox banksia, is a shrub (occasionally a tree) in the family Proteaceae. Generally 1–2 m (3.3–6.6 ft) high, this banksia has narrow green leaves and, from January to July, brownish, orange or yellow round flower spikes. The species is widely distributed across the southwest of Western Australia, growing exclusively in sandy soils. A dominant plant in scrubland or low woodland, it is pollinated by, and is a food source for, birds, mammals, and insects. First described in 1810 by botanist Robert Brown, the species has a complicated taxonomic history, and several taxa once classified as part of a broadly defined B. sphaerocarpa have since been named as species in their own right. Most authorities recognise five varieties; the largest, B. sphaerocarpa var. dolichostyla (ironcap banksia), is sometimes given species rank as B. dolichostyla. According to the Wildlife Conservation Act of Western Australia, B. sphaerocarpa is not threatened. None of the varieties is commonly seen in cultivation. (Full article...)
