- Description
- Grevillea hockingsii is a dense, compact, upright shrub, 1.5 to 2.5 m in height. The branchlets are angular and silky. The leaves are 4 to 14 cm long by 4 to 18 mm wide. The sides of the leaves are roughly parallel or are broadest in the centre and taper to each end. The leaf tips are short and soft. The upper leaf surface when young is covered in silky purple-pink hairs which are lost when mature. The lower leaf surface is covered in silvery or light rust coloured silky hairs. The midvein is prominent on the lower leaf surface. The sides of the leaves curve slightly downwards. Flower heads (conflorescence) grow from the axis of the leaves with the stems or can grow directly from the stem in old wood. Conflorescences have 6 to 14 flowers (usually 10) which are arranged on a single stem, like spokes on a wheel. The flowers are a bright pinkish purple and 11 to 15 mm long by 2 to 2.5c m wide. The seeds are 11 to 13mm long, 3 to 4.5 mm wide and 1.5 to 2 mm thick. Seed dispersal is promoted by a triangular, 2 to 3 mm long seed appendage (elaiosome) which ants eat. (Barker, 1996).

- Habitat
- Grevillea hockingsii is found on slopes in hilly sandstone country on shallow sandy to sandy loam soils which are light brown to red in colour and occasionally stony or gravelly. It grows in woodland or open forest communities mostly dominated by either Eucalyptus decorticans (gum-topped ironbark) and Corymbia citriodora subsp. variegata (spotted gum), Eucalyptus suffulgens or E. acmenoides (white mahogany). Occasionally it is found on the edge of soaks containing species of Melaleuca (Barker, 1996).
- Reproduction
- Grevillea hockingsii flowers from April to December. Nectivorous birds, possibly the White-throated Honeyeater, have been observed feeding at the flowers. Regeneration is from seed. (Barker, 1996).
- Threatening processes
- Possible threatening processes include, disturbance of habitat by timber harvesting, inappropriate fire regimes, destruction of habitat due to clearing for agriculture and mining, and inappropriate grazing regimes (Barker, 1996).
- Status notes
- Grevillea hockingsii is listed as Vulnerable under the Queensland Nature Conservation Act 1992

- Management recommendations
- Management recommendations for the protection of Grevillea hockingsii includes: the establishment of a protective buffer (0.25ha) that excludes clearing with all G. hockingsii at least 25m inside the buffer; where the species occurs the interval between prescribed burns to vary from 10-30 years (based on the minimum age at which the plant sets seeds); and monitor the impact of grazing and adjust grazing management to ameliorate adverse impacts (Barker, 1996).
- Notes
- Occurs in the following Queensland pastoral districts: Burnett, Port Curtis.
