Description
editGrevillea vuniana is a shrub or small tree that typically grows to a height of up to 6 m (20 ft). Its leaves are egg-shaped, elliptic, spatula-shaped to wedge-shaped mostly 130–200 mm (5.1–7.9 in) long, 40–62 mm (1.6–2.4 in) wide on a petiole 7–12 mm (0.28–0.47 in) long. The flowers are borne in groups of 20 to 40 on the ends of branches, on a peduncle 18–25 mm (0.71–0.98 in) long, each flower on a pedicel 7–10 mm (0.28–0.39 in) long and reddish. The fruit is flattened, ridged and glabrous with the remain of the style attached.[3][4]
Taxonomy
editGrevillea vuniana was first formally described in 2020 by Yohan Pillon in the journal Phytotaxa . The specific epithet (vuniana) is from the name of the nearby tribe of Unia, ("Vunia" in the local language), where the plant was located.[3]
Distribution and habitat
editGrevillea vuniana has only been seen in the vicinity of Lake Chakeke. It is found in a low wet forest and along the forest edge, where it is in proximity to a temporary lake and a temporary river.[3][4] The species occurs 100–500 m (330–1,640 ft) above sea level.[5] Its population size is assumed to be very small and the area it occupies is assumed to be about 4 km2 (1.5 sq mi).[3][5]
