Description

Grevillea decora is an erect shrub or small tree that typically grows to a height of and has a single main stem. Its leaves are oblong, oval or egg-shaped, long and wide, the lower surface densely silky-hairy. The flowers are arranged near the ends of the branchlets on a one-sided rachis long, the pistil long. Flowering time varies with subspecies and the fruit is a follicle long.^{[1] [2] [3]}

Taxonomy

Grevillea decora was first formally described in 1921 by Karel Domin in the journal Bibliotheca Botanica from specimens he collected near Pentland in 1910.^{[4] [5]} The specific epithet (decora) means "beautiful".^[6]

In 2000, Robert Owen Makinson described two subspecies in the Flora of Australia and the names are accepted by the Australian Plant Census:

• Grevillea decora Domin subsp. decora^[7] has branchlets covered with mostly rusty-brown hairs, leaves long, rusty-brown flower buds, a pistil long and flowers from January to September;^[8]
• Grevillea decora subsp. telfordii Domin^[9] has branchlets covered with mostly silvery-grey hairs, leaves long, pinkish flower buds, a pistil long and flowers mainly from March to June.^[10]

Distribution and habitat

Subspecies decora grows in woodland shrubland in shallow soil over sandstone and occurs in patchy locations along the ranges of inland eastern Queensland from near Wandoan to near Pentland but subspecies telfordii grows in heath and forest near Laura in far north Queensland.

Conservation status

G. decora is listed as Least Concern on the IUCN Red List of Threatened Species. Both subspecies of are listed as of "least concern" under the Queensland Government Nature Conservation Act 1992.^{[11] [12] [13]}
