Hibbertia empetrifolia subsp. empetrifolia

Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Spreading to prostrate shrubs; branches pubescent to puberulous, to c. 40 cm long. Vestiture of tubercle-based, mainly simple hairs (sometimes hooked) over scattered stellate hairs. Leaves narrowly elliptic to oblong-oblanceolate, 4–14 mm long, 0.7–6.1 mm wide, sparsely pubescent; petiole 0.2–0.9 mm long; apex obtuse to rounded, rarely mucronate with central vein scarcely protruding; margins narrow, revolute, distant from scarcely raised central vein. Flowers on peduncle 2–6(–10.4) mm long, terminal, but often apparently axillary when on reduced short shoots or on main branches with continued axillary growth, subtended by 1 subulate bract 1.2–2.5 mm long, half as long to subequal to sepals; sepals 2.5–4.6 mm long, unequal, pubescent; petals oblanceolate- to obovate-cuneate, 3.1–6 mm long, mid yellow; stamens (4–)5–7(–9); filaments connate basally; carpels 2, tomentose to villous with stellate or forked hairs. Flowers Aug.–Feb.

EGL, GipP, HSF, WPro. Locally common in well-watered forest, woodland or heathland east from Port Phillip Bay.

Three subspecies described, defined largely on the vestiture of the upper leaf surface, one present in Victoria. Subspecies uncinata occurs north of Sydney, and has hooked simple hairs as well as few-branched stellate hairs (with less than 4 branches) on leaves and sepals. Subspecies radians occurs in South Australia, and has many-branched stellate hairs (more than 8 branches) with a broad tubercle-base on the upper leaf surface. Subspecies empetrifolia is somewhat intermediate between the other 2 subspecies; hooked hairs may be present or absent, and stellate hairs have 5–14 branches.

Hibbertia empetrifolia resembles H. appressa (see note under that species). Furthermore, leaves of H. empetrifolia can resemble juvenile forms of H. aspera and allied species (i.e. H. hirticalyx, H. notabilis, H. pallidiflora and H. truncata). Like H. empetrifolia, the lower surface of juvenile leaves of H. aspera and allies have stellate hairs that are largely confined to the central vein, while simple hairs are present on the lamina. However, the juvenile leaves of H. aspera and allies have a much greater density of simple hairs on the lamina, and these are soon replaced by a dense layer of stellate hairs.
