Richea × curtisiae, commonly known as Curtis's candle heath, is a hybrid species of plant endemic to Tasmania. It belongs to the genus Richea, which forms part of the Ericaceae (formerly Epacridaceae) family, commonly known as the heath family.
Richea × curtisiae is a hybrid species between Richea scoparia and Richea pandanifolia.[1]
Richea × curtisiae has the form of an intermediate between the smaller shrub Richea scoparia and the larger erect shrub/tree Richea pandanifolia. As such, Richea × curtisiae forms a small shrub of between tall with an erect habit. Richea × curtisiae has few branches, with persistent leaves. These leaves are tapering and strap-like, which vary in length from .[2] The leaf margins are cartilaginous and are finely serrated and cutting, and the branch tips contains a dense rosette of leaves. As the leaves age they become brown, and the leaves on the lower two-thirds of the stem are dead and decaying.
The inflorescence of Richea × curtisiae occurs as a terminal panicle, a branched inflorescence, which are between long. The peduncles, the stalks of the flowers, are 5 to 10 in number, and are short, between .[3] The flowers are pink to orange in colour.
Richea × custisiae has an appearance similar to that of Richea alpina, but it is shorter, unbranched, and broadly spreading, and is restricted to alpine areas in the deep south-west.
Richea × custisiae is endemic to Tasmania and is relatively common in occurrence where both Richea scoparia and Richea pandanifolia occur, with heightened occurrence after a disturbance, like that of fire or clearing.
Richea × curtisiae occurs in alpine areas of the West and Central mountains of Tasmania. It can be found in sub-alpine woodlands, and sub-alpine heath communities. Richea × curtisiae also often occurs with Dracophyllum milliganii.[4]
Richea × curtisiae was first recognised in 1971 by Alan Maurice Gray, and was named after Winifred Curtis, a matriarch in Tasmanian botany.[5]
