Lomatia arborescens, commonly known as smooth lomatia or tree lomatia, is a shrub or small tree that grows at high altitudes, in and near rainforests. It is found north from the Barrington Tops area in eastern Australia. [2]

Description

Lomatia arborescens grows as a large shrub or small tree to 10 m (35 ft) high, with greyish brown bark. The smooth leaves are oval to spear-shaped (lanceolate) and measure 3 to 15 cm (1.2–6 in) in length by 1.5 to 6 cm (0.6-2.2 in) wide—generally larger and with serrated leaf margins in sheltered spots and smaller with entire margins in exposed locations. A network of veins can be seen on the upper surface of the leaves. [3]

The white flowers grow in racemes that arise from axillary buds, appearing over the summer. [3]

Taxonomy

Lomatia arborescens was first formally described in 1937 by Lilian Fraser and Joyce Winifred Vickery, from a specimen collected by them on 12 January 1934 in rainforest along the Williams River. [4] [5] The species name is derived from the Latin arbor, "tree", hence, "tree-like". [6]

George Bentham had described Lomatia longifolia var. arborescens as a variety of Lomatia longifolia (now Lomatia myricoides ) in his 1870 work Flora Australiensis , describing it as a "small tree of 20 to 25 ft" from the "Sydney woods". [7] The identity of this form is unclear, with Alexander Floyd stating it was L. arborescens and the authors of Flora of Australia identifying it as L. myricoides. [8]

It was mistakenly called L. ilicifolia by Queensland botanist Frederick Manson Bailey in his 1901 work Queensland Flora. [4] [9]

Analysis of chloroplast DNA showed that there is extensive hybridization between the five species (L. arborescens, L. fraseri, L. ilicifolia, L. myricoides and L. silaifolia ) of mainland southeastern Australia, though each is distinct enough to warrant species status. [10]

Distribution and habitat

Lomatia arborescens is found from southern Queensland southwest to Mount Kaputar National Park and south to Barrington Tops. It grows in rainforest and rainforest margins. [3]

Cultivation

Lomatia arborescens adapts readily to cultivation with a sunny or part-shaded aspect. [6] Horticulturally, it is of potential because of its attractive leaves rather than its flowers, which are not prominent. In cultivation, it requires some degree of moisture. [9]
