Description

Hibbertia echiifolia is a sometimes spreading shrub that typically grows to a height of 0.2–3.5 m (7.9 in – 11 ft 5.8 in), its branches covered with scale-like hairs. The leaves are elliptic to lance-shaped or oblong, 5–73 mm (0.20–2.87 in) long and 1–17 mm (0.039–0.669 in) wide and sessile or on a petiole up to 1 mm (0.039 in) long. The flowers are arranged singly in up to three leaf axils at the ends of branchlets and sessile or on a thick peduncle up to 23 mm (0.91 in) long, with lance-shaped bracts 3.5–11 mm (0.14–0.43 in) long. The five sepals are joined at the base, the two outer sepal lobes 3–14 mm (0.12–0.55 in) long and the inner lobes longer. The five petals are egg-shaped with the narrower end towards the base, yellow, 7–17 mm (0.28–0.67 in) long with two lobes on the end. There are twenty-nine to forty-five stamens of differing lengths arranged in groups around the three carpels, each carpel with two ovules. Flowering occurs from April to July. [2] [3] [4]

Taxonomy and naming

Hibbertia echiifolia was first formally described in 1863 by George Bentham in Flora Australiensis from an unpublished description by Robert Brown. [5] [6] The specific epithet (echiifolia) means "leaves similar to those of plants in the genus Echium ". [7]

In 2010, Hellmut Toelken described five subspecies and the names are accepted by the Australian Plant Census:

The subspecies' names (other than that of the autonym echiifolia) mean "drooping" (cernua), "large-flowered" (macrantha), "few-flowered" (oligantha) and "wheeled" (oligantha), the last referring to the wheel-like appearance of the hairs. [2]

Distribution and habitat

This variable hibbertia occurs in the Kimberley region of Western Australia, the northern part of the Northern Territory on the Cape York Peninsula in Queensland. Subspecies cernua grows in scrub in Arnhem Land in the Northern Territory, subspecies echiifolia in heath in coastal areas of the northern Kimberley, north-eastern Northern Territory and Cape York Peninsula, macrantha in woodland, mainly in Arnhem Land, oligantha in rocky places in woodland in Arnhem Land and subspecies rotata in woodland on sandstones or scree slopes in Arnhem Land. [2]

Conservation status

Goodenia echiifolia is classified as of "least concern" under the Northern Territory Government Territory Parks and Wildlife Conservation Act 1976 and as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [4] [3]
