Grevillea integrifolia, commonly known as entire-leaved grevillea, is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect shrub with egg-shaped leaves, the narrower end towards the base, and cylindrical clusters of white to creamy-white flowers.
Grevillea integrifolia is an erect shrub that typically grows to a height of . Its leaves are egg-shaped with the narrower end towards the base, long and wide, sometimes curving upwards. The flowers are white to creamy-white, sometimes with a pink tinge and are arranged in cylindrical, sometimes branched clusters on a rachis long. The pistil is long and glabrous. Flowering mainly occurs from October to December and the fruit is a smooth, narrowly oblong follicle long.[1]
The species was first formally described in Stirpium Australasicarum Herbarii Hugeliani Decades Tres in 1830 by Austrian botanist Stephan Endlicher who gave it the name Anadenia integrifolia.[2] [3] The species was transferred to the genus Grevillea as Grevillea integrifolia by Swiss botanist Carl Meissner in 1856.[4] The specific epithet (integrifolia) means "whole-leaved", that it not toothed or lobed.[5]
Entire-leaved grevillea usually grows in heath and occurs near Burracoppin, Quairading, Kukerin and Corrigin in the Avon Wheatbelt, Jarrah Forest and Mallee bioregions of south-western Western Australia.
