Phaleria clerodendron, commonly known as scented daphne, scented phaleria or rosy apple, is an evergreen tree or tall shrub in the family Thymelaeaceae. It is endemic to the rainforests of north-eastern Queensland, Australia.[2]

Description

The scented daphne grows as a large shrub or small tree, usually around 3.5 m (11 ft) in height but may be up to 10 m (33 ft).[2][5] It is often multi-stemmed and may be buttressed.[6][7] The glabrous (glossy) dark green leaves are simple, measure 9–20 cm (3.5–7.9 in) long by 4–7.5 cm (1.6–3.0 in) wide, and are attached to the twig with a petiole around 1 cm (0.39 in) long.[2][5]

Flowering occurs from October to April and the inflorescences mostly arise from the branches (ramiflorous), or from the trunk (cauliflorous), but may also arise in the leaf axils.[6][7] The fragrant, clustered, white flowers have a very long corolla tube up to 40 mm (1.6 in) long, much longer than the petals.[2][5] They are followed by globose, fleshy, red fruits which are a drupe, and they ripen between December and July.[6]

Taxonomy

Ferdinand von Mueller initially described the species in 1869 as Drimyspermum clerodendron in his work Fragmenta Phytographiae Australiae (vol.7), from material collected by John Dallachy at Rockingham Bay.[8] In 1873 George Bentham published another description in Flora Australiensis (vol.6), in which it was given the current binomial combination.[9]

Etymology

The genus name Phaleria comes from the Ancient Greek φάλαρος (phálāros) meaning "having a white spot"; the species epithet clerodendron refers to a resemblance to the genus Clerodendrum.[10]

Distribution and habitat

P. clerodendron is endemic to north-eastern Queensland, with recorded occurrences from near Cooktown in the north to Cardwell in the south. It grows in well developed rainforest at altitudes ranging from sea level up to about 900 m (3,000 ft), thus it is found in almost all parts of—and entirely contained within—the Wet Tropics of Queensland World Heritage Area, with the exception of the highest peaks and the most southern section.[2][5]

Ecology

Fruits of the scented daphne are eaten by cassowaries.[2][6]

Conservation

This species is listed by the Queensland Department of Environment and Science as least concern.[1] As of 3 July 2021, it has not been assessed by the IUCN.

Cultivation

The species is regarded as an attractive garden ornamental due to its dark green foliage, the spectacular and pleasantly-scented flower clusters, and the colourful fruit. It may be grown with the correct care as far south as Sydney.[2][7][11][12]
