Appearance
"Grevillea maccutcheonii" is a densely-branched shrub that typically grows to 2 m high and 3 m wide and has ridged branchlets. The leaves are mostly 10–25 mm long, 7–15 mm wide, stem-clasping and more or less cross-shaped in outline, with three spiny lobes. Sometimes the leaves are simple and fiddle-shaped with three teeth near the tip. The edges of the leaves are wavy and both surfaces are glabrous. The flowers are arranged in erect clusters of 26 to 28 on one side of a glabrous rachis 5–10 mm long. The flowers are reddish green, the pistil 28–30 mm long. Flowering occurs in most months with a peak from July to November, and the fruit is a glabrous, narrowly oval follicle 13–17 mm long.Distribution
McCutcheon's grevillea is restricted to the foot of the Whicher Range where it grows in moist, tall shrubland.Status
This grevillea is listed as "endangered" under the Australian Government "Environment Protection and Biodiversity Conservation Act 1999" and as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, meaning that it is in danger of extinction. The main threats to the species include habitat degradation, road maintenance, weed invasion and grazing by rabbits. The total population of mature plants was estimated to be seven in 2007, and a single disturbance event could destroy the entire wild population.Habitat

Unlike many Western Australian plants, McCutcheon's grevillea adapts well to cultivation, even in the eastern states, where summer humidity is often high. It grows best in well-drained soil in a sunny location.References:
