Description

Grevillea × gaudichaudii is a naturally occurring hybrid between Grevillea acanthifolia subsp. acanthifolia and Grevillea laurifolia, growing as a prostrate plant in diameter. Its leaves are pinnately-lobed, the lobes oblong to egg-shaped and softly-hairy on the lower surface but not sharply pointed. The flowers are arranged in toothbrush-like racemes less than long and are dark pink to burgundy-red, the style more than long and the ovary stalked and glabrous. Flowering occurs from October to December.[1] [2] [3]

Taxonomy

Grevillea × gaudichaudii was first formally described in 1827 by Charles Gaudichaud-Beaupré in Voyage autour du monde, entrepris par ordre du roi from an unpublished description by Robert Brown of plants collected in the Jamieson Valley (near Katoomba).[4] [5]

Distribution and habitat

This grevillea grows in sandy soil and is restricted to parts of the higher Blue Mountains.[6]
