Pomaderris ligustrina explained

Pomaderris ligustrina, commonly known as privet pomaderris,[1] is a species of flowering plant in the family Rhamnaceae and is endemic to south-eastern continental Australia. It is a shrub with hairy stems, lance-shaped to narrowly elliptic leaves, and loose clusters of cream-coloured or yellow flowers.

Description

Pomaderris ligustrina is a shrub that typically grows to a height of, its branchlets covered with both simple and rust-coloured, star-shaped hairs when young. The leaves are usually lance-shaped to narrowly elliptic, long and wide with stipules long at the base but that fall off as the leaf develops. The upper surface of the leaves is glabrous and the lower surface covered with silky, rust-coloured hairs. The flowers are creamy-white to yellow and arranged in loose panicles long, each flower on a pedicel long. The floral cup is long, the sepals long but fall off as the flowers open, and there are no petals. Flowering occurs in September and October.[2] [3]

Taxonomy

Pomaderris ligustrina was first formally described in 1825 by Augustin Pyramus de Candolle in Prodromus Systematis Naturalis Regni Vegetabilis from an unpublished description by Franz Sieber.[4] [5] The specific epithet (ligustrina) means "privet-like".[6]

In 1997, Neville Grant Walsh and Fiona Coates described subspecies latifolia in the journal Muelleria and the name, and that of the autonym are accepted by the Australian Plant Census:

Distribution and habitat

Privet pomaderris grows in forest on the ranges and escarpments from south-east Queensland and New South Wales to as far west as Bairnsdale in Victoria. Subspecies latifolia is rare and only occurs in south-eastern Queensland and as far south as Guyra in northern New South Wales.[10]
