Scientific name: Grevillea glossadenia
Grevillea glossadenia is a compact, dense, grey-brown shrub to 2 m tall. Leaves are elliptic with slightly recurved margins, have a silky, prominently veined lower surface and grow to 12 cm long. Deep, yellow-orange to orange-red flowers occur in loose clusters (Makinson 2000b; Wrigley & Fagg 1989).
Grevillea glossadenia occurs in north-east Queensland mainly in the Einasleigh Uplands Interim Biogeographic Regionalisation for Australia (IBRA) bioregion, with a few collections from the Wet Tropics Bioregion (ALA 2013). It mainly occurs between Walkamin, Irvinebank, Herberton and Watsonville (Makinson 2000b; Olde & Marriott 1995). Localities include Mount Emerald, Mount Misery, Cooloomon Creek, Little Cooloomon Creek, Emu Creek, Granite Creek and Barkerville (Queensland Herbarium 2008b). Olde and Marriott (1995a) reported this species as occurring west of Chillagoe but it is now believed that this record refers to G. decora (Forster 2001 pers. comm.).
No collections have been made in protected areas (ALA 2013). The species has been in cultivation for more than 20 years and is widely cultivated in Queensland (Olde & Marriott 1995a; Wrigley & Fagg 1989).
Grevillea glossadenia grows in eucalypt woodland or low open forest, in shallow to skeletal granitic soils on rolling hills, gravel terraces near stream beds, and along roadsides and mining tracks (Makinson 2000b; Queensland Herbarium 2008). It occurs in areas of 1000–1300 mm rainfall and has been recorded as being able to tolerate frosts as low as -8 °C (Olde & Marriott 1995a).
Associated plant species include Gympie Messmate (Eucalyptus cloeziana), E. pachycalyx, Ramornie Stringybark (E. tindaliae), Cullen's Ironbark (E. cullenii), E. atrata, Range Bloodwood (Corymbia abergiana), Yellow Jacket (C. leichhardtii), White Bloodwood (C. trachyphloia), C. watsoniana, Lemon-scented Gum (C. citriodora), Northern Cypress Pine (Callitris intratropica), Red Ash (Alphitonia excelsa), Acacia purpureopetala, Homoranthus porteri, Leptospermum amboinense and Xanthorrhoea johnsonii (Gleed 2005; Queensland Herbarium 2008b).
Grevillea glossadenia flowers year round, but mainly in April to August and, in its natural environment, probably regenerates from seed only (Makinson 2000b). This species may favour disturbed sites (McGillivray 1993).
Grevillea glossadenia has been successfully grown ex-situ from seed, cuttings and grafts on Silky Oak (G. robusta) and G. 'Poorinda Anticipation' (Olde & Marriott 1995a). Seeds will germinate freely if given the standard peeling treatment, but cuttings are generally slow to produce roots (Olde & Marriott 1995a).
All Grevilleas are protandrous (anthers release their pollen before the stigma of the same flower is receptive) and hermaphroditic (male and female parts on flowers) (Collins & Rebelo 1987). The general foraging of pollinators (particularly birds and insects) facilitates both outcrossing and self-pollination (Collins & Rebelo 1987). Birds, mammals and arthropods have been identified as visitors to the inflorescences of many species in the Proteaceae family (Collins & Rebelo 1987; Olde & Marriott 1995a) and the most common visitors to Australian plant species in this plant family are honeyeaters, lorikeets, silvereyes and forty other bird species that may be important visitors (Collins & Rebelo 1987). For those Proteaceae species that rely on arthropods for pollination it is possible that only the larger moths, bees and beetles are important pollinators (Collins & Rebelo 1987). In most Grevilleas, the fruit set is low relative to the number of flowers produced (Collins & Rebelo 1987).
The main potential threats to Grevillea glossadenia are: disturbance associated with mining operations, invasive weeds, and extinction associated with stochastic events (ANRA 2009; Gleed 2005; Radke & Radke 1983). Habitat associated with this species is infested in places by many weeds, particularly Sisal (Agave sisalana) and Panic Grass (Panicum maximum), which may prevent growth of Grevillea glossadenia (Gleed 2005).
Managment documents relevant to Grevillea glossadenia are at the start of the profile.
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
