Common name: Tree Violet
Melicytus dentatus (DC.) Molloy & Mabb. APNI*
Synonyms: Hymenanthera dentata R.Br. ex DC. APNI*
Description: Erect to spreading shrub to 2–5 m high, up to 6 m across, usually dioecious. Bark smooth, grey, with lenticels.
Leaves mid- to dark green, lower surface paler than upper. Juvenile leaves usually broad-obovate, conspicuously dentate, often larger than adult leaves. Adult leaves oblong or narrow-elli[ptic to narrow-obovate, 25–40 mm long, 4–6 mm wide, solitary or in groups, margins callus-toothed or serrate.
Inflorescences 1- or 2- (rarely more) flowered, axillary to old leaves or their petiole scars, on short shoots, 1 or 2 per axil. Bracteoles deltoid. Sepals unequal, imbricate. Corolla broad-cylindric. Petals fleshy; male flowers usually daphne-scented, pale yellow to lemon yellow, anthers sessile, creamy yellow; female flowers mildly sweet-scented, off-white or pale yellow
Fruit an ellipsoid to ovoid berry 7–8 mm long, 5–7 mm in diameter, initially green, maturing to uniformly bluish-grey to dark mauvish-grey or completely white, calyx persistent. Pyrenes 1 or 2, smooth, 3–4 mm long.
Flowering: Flowering occurs from early August to mid–October, at least partly depending on altitude. Fruits mature between December and March.
Distribution and occurrence: Occurs from far south-eastern Queensland in the Nandewa rregion, through to the Nandewar, New England Tablelands and South East Corner in eastern New South Wales, and extending south to the Victorian Midlands in the north-eastern part of that State and to the Naracoorte Coastal Plain in south-western Victoria. Further collecting is required to establish whether M.dentatus is present in Tasmania.
Grows in a wide variety of habitats, usually in open forests and woodlands, often near lakes, swamps or watercourses, from near sea level to c.1000 m above sea level at Mount Tomah in the Blue Mountains, New South Wales. Soils are usually sandy, derived from sedimentary parent materials, or alluvial, rarely volcanic, clays.
