Rhododendron; Rhododendron, Native; Native Rhododendron
Usually grows as a shrubby epiphyte in the tree tops but can flower and fruit as a lithophytic shrub.
Leaf blades rather thick and leathery, about 5.5-10.5 x 3-6.5 cm, cracking when folded. Lateral veins form loops inside the blade margin. Underside of the leaf blade marked by numerous dark peltate scales. Petiole channelled on the upper surface.
Corolla +/- campanulate, about 3-4 x 2.5-3 cm, +/- glabrous outside but marked by glands. Corolla tube straight or slightly curved. Stamens ten, anthers brown, filaments red, glabrous or pubescent. Base of the ovary surrounded by a lobed disk with the staminal filaments inserted in the indentations. Pollen white. Ovary clothed in erect white hairs. Basal half of the style clothed in white hairs. Stigma 4-lobed.
Capsule rather long and narrow before dehiscing, about 20-40 mm long. Seed +/- filiform, about 2-5 mm long with a slender somewhat twisted wing on each end. Embryo cylindrical, cotyledons about as wide as the radicle. Seeds may germinate inside the capsule.
Cotyledons obovate, ovate to elliptic, about 1.5-3 x 0.5-1 mm. First pair of true leaves obovate, about 2-3 x 1 mm, apex obtuse, base cuneate, glabrous, petiole about 1 mm long, lateral veins not visible. At the tenth leaf stage: all seedling parts clothed in pale brown scale-like glands which are visible to the naked eye. Leaf blade elliptic-obovate, about 8 x 5 mm, apex obtuse, midrib depressed on the upper surface. Lateral veins difficult to distinguish. Terminal bud scaly.
Distribution and Ecology
Endemic to NEQ, occurs on Mt Lewis, Mt Spurgeon, Pinnacle Rock, the Windsor Tableland, Mt Finnigan, Mt Pieter Botte, Thornton Peak, Bell Peak, the Bellenden Ker Range and Mt Bartle Frere. Altitudinal range from 940-1300 m. Grows as an epiphyte in well developed rain forest but also found as a lithophytic shrub on boulders in stunted windswept rain forest on mountain tops.
A very attractive small to large shrub with striking bright pink, bell-shaped flowers and has been in cultivation in Australia and overseas for more than 60 years.
