- Description
- Parsonsia kroombitensis is a climber growing to 2 m high, or often in clumps suspended from rock crevices. The stems are minutely puberulous and have clear latex. The leaves are lanceolate, linear-lanceolate or deltoid, 2 to 6 cm long by 0.6 to 1.9 cm wide and are arranged opposite each other in pairs along the branches. The leaves are glabrous or the lower surface maybe minutely puberulous; dark purple or purplish brown when dried, with a recurved margin that is acuminate, apiculate; the veins are impressed above; lower surface with secondary veins and coarser net veins prominent. The inflorescence is axillary, occasionally terminal, in open cymes with 2 to 9 orange-yellow flowers. The calyx lobes are recurved, puberulous and 2.5 mm long. The corolla is orange-yellow, red in the throat and at the base of the lobes, white on the margins; the tube is cylindrical, 4.5 mm long, conspicuously bearded with glistening hairs. The corolla lobes are glabrous, narrowly obovate with a thickened medium strip, 4 to 5 mm long and 2.8 mm wide. The fruit capsules are very narrow ovoid, 4 to 10 cm long by 0.7 to 1 cm in diameter (Williams, 1996; Wang, 1998).

- Distribution
- Parsonsia kroombitensis is restricted to central east Queensland. The species is currently known from Kroombit Tops National Park (4 populations) and the Boyne Range State Forest (1 populations), both occurring south west of Gladstone, and Cania Gorge National Park (1 population within the park and 1 outside), north west of Monto (Wang, 1998; Queensland Herbarium, 2010).

- Habitat
- Parsonsia kroombitensis occurs on escarpments at the edges of deep valleys, among outcrops of acidic volcanic rocks and on rocky brown loam, skeletal derived from sandstone. The species grows in low shrubby woodland with Eucalyptus acmenoides, E. eugenioides, E. montivaga, E. crebra and Corymbia trachyphloia. The species also grows in open shrubland and in lithophytic vegetation, where associated species include Jacksonia scoparia, Philotheca myoporoides, Xanthorrhoea spp., Hoya australis and ferns Williams, 1996; Wang, 1998, Queensland Herbarium, 2011).
- Behaviour
- Parsonsia kroombitensis often occurs in clumps hanging down from rock crevices (Wang, 1998).
- Reproduction
- Flowering of Parsonsia kroombitensis has been recorded in February-April. Fruiting has been recorded in July and September (Wang, 1998; Queensland Herbarium, 2011).
- Threatening processes
- Parsonsia kroombitensis has a very restricted and fragmented distribution. Possible threatening processes include fragmentation of habitat, disturbance of habitat due to timber harvesting, inappropriate fire regime and bush walking (Wang, 1998).
- Status notes
- Parsonsia kroombitensis is listed as Vulnerable under the Queensland Nature Conservation Act (1992)

- Management recommendations
- Management actions for the protection of Parsonsia kroombitensis and its habitat include: the establishment of protective buffer (0.25ha) that excludes clearing with all P. kroombitensis at least 20 m inside the buffer; route walking and other tracks away from known populations of P. kroombitensis; maintain current prescribed burning practices, but ensure sites are not burnt annually (Wang, 1998).
- Notes
- Occurs in the following Queensland pastoral districts: Port Curtis (Bostock and Holland, 2010).
