Description edit
Seringia × katatona is an erect, compact shrub with many stems, and that typically grows up to 0.5–1.0 m (1 ft 8 in – 3 ft 3 in) high, 1 m (3 ft 3 in) wide, and sometimes forms suckers. The leaves are arranged alternately, at first trilobed or egg-shaped, about 35 mm (1.4 in) long and 18 mm (0.71 in) wide, later oblong, 12–28 mm (0.47–1.10 in) long and 6–10 mm (0.24–0.39 in) wide on a petiole 2.5–6 mm (0.098–0.236 in) long with narrowly egg-shaped stipules 2.0–4.5 mm (0.079–0.177 in) long at the base. The flowers are arranged in a cyme 9–17 mm (0.35–0.67 in) long with 9 to 17 flowers on a peduncle 3–7 mm (0.12–0.28 in) long, each flower on a pedicel 7–11 mm (0.28–0.43 in) long. The flowers are purple with petal-like, broadly egg-shaped sepals 7–9 mm (0.28–0.35 in) and joined at the base to form a tube with lobes half the length of the tube. Petals are absent, the staminodes tiny, and the filaments and anthers are yellow. Flowering occurs from March to August.[2][3][4]
Taxonomy edit
In 1999, Carolyn F. Wilkins described Keraudrenia katatona in the journal Nuytsia from specimens collected near the Broome airport in 1995.[3][5] In 2016, Wilkins and Barbara Ann Whitlock changed the name to Seringia × katatona in Australian Systematic Botany.[6] The specific epithet (katatona) means "broader than high", referring to the sepals.[7]
Distribution and habitat edit
Red dune fire-bush grows in red sand on desert dunes and is restricted to near Broome and near Port Hedland in the Dampierland and Great Sandy Desert bioregions of northern Western Australia.[2]
Conservation status edit
Seringia × katatona is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[2]
