Hoya macgillivrayi, commonly known as red hoya or Macgillivray's wax flower,[1] is a species of vine endemic to Cape York Peninsula in Queensland, and has egg-shaped to lance-shaped leaves and racemes of dark reddish-pink flowers, sometimes with a white centre, and a reddish-pink corona.
Description
Hoya macgillivrayi is a vine with stems less than Template:Cvt in diameter and containing white, milky sap. Its leaves are glabrous, egg-shaped to lance-shaped, up to Template:Cvt long and to Template:Cvt wide with two to five colleters. The flowers are fleshy, glabrous, flattened bell-shaped, dark reddish-pink, sometimes with a white centre, Template:Cvt in diameter with six to ten flowers. Each flower is on a pedicel Template:Cvt long and has narrowly oblong lobes Template:Cvt long and Template:Cvt wide with the edges curved down. The corona has linear lobes Template:Cvt long and Template:Cvt wide and reddish-pink. Flowering occurs from May to October and the fruit is a follicle about Template:Cvt long and Template:Cvt wide.[2][3][4][5]
Taxonomy
Hoya macgillivrayi was first formally described in 1914 by Frederick Manson Bailey in the Queensland Agricultural Journal from specimens collected by William MacGillivray near "Claudie River, Lloyd Bay".[6][7] The specific epithet (macgillivrayi) honours the collector of the type specimens.[5]
Distribution and habitat
This species of Hoya grows in rainforest and monsoon forest in the Iron and McIlwraith Ranges on Cape York Peninsula, from sea level to Template:Cvt.[3][5]
Conservation status
Hoya macgillivrayi is listed as "near threatened" under the Queensland Government Nature Conservation Act 1992.[1]
Use in horticulture
This species requires a loose, friable peaty soil mixture and good drainage. Plants perform better when root-bound, with small applications of slow-release fertiliser at nine-monthly intervals.[5]
