Leptomeria drupacea, also known as the pale currant bush, is an endemic Australian hemi-parasitic erect shrub. It occurs commonly in dry woodlands across Tasmania Australia and in some parts of Victoria and Queensland. It has long yellowish-green slender branchlets that often give a broom-like appearance.
Leptomeria drupacea is an upright green shrub that can grow up to 3m. Its flexible, almost cylindrical branchlets have longitudinal ridges, and its leaves and bracts are sessile and scale-like with a truncate base and a narrowly acute apex; 0.71mm long, 0.30mm wide.[2]
Its flowers are bisexual and are arranged into a raceme of around 10-16 flowers, which is typically inserted laterally to the branchlets. The pedicel of the flowers is obscure and hard to differentiate from the floral tube. The white to cream tepals (flushed reddish-pink upon ageing), 0.61mm long, are concave with an incurved and adaxially thickened apex that forms a hood with tiny hairs on the adaxial surface, restricted to small tufts. The floral disk is deeply lobed with a diameter of 0.60mm and the anthers, filaments and style are typically 0.10- 0.15mm long.[2][3]
The smooth drupe, 3-6mm, are oval to almost round with a fleshy thick epicarp. The drupes start green, ripen reddish and are edible. Flowering occurs late spring to summer.[3]
Taxonomy
Leptomeria drupacea is part of the Santalaceae family which includes around 30 different genera and 400 species across the world in tropical and temperate regions. This family was first described in 1810 in Robert Brown’s Prodromus Flore Novae Holllandiae, which was based on specimens collected in 1802-1805 whilst on the Matthew Flinder’s circumcontinental voyage to Australia.[4] The Australian endemic genus Lemptomeria, from the Geek word ‘leptos’ meaning slender and ‘meros’ meaning part, referencing to the slender branches, consists of 17 different species in the southern parts of Australia. The species name Drupacea is derived from the Latin meaning 'like a drupe’.[3]
