Grevillea parallelinervis is a species of flowering plant in the family Proteaceae and is endemic to South Australia. It is a spreading shrub with sharply-pointed, linear leaves, and down-turned clusters of red flowers with a green-tipped style.
Grevillea parallelinervis is a shrub that typically grows to a height of and has silky- to woolly-hairy branchlets. Its leaves are linear, long, wide and sharply pointed. The edges of the leaves are rolled downwards, obscuring the lower surface, apart from the mid-vein. The flowers are arranged in down-turned clusters in leaf axils on one side of a rachis long, each flower on a pedicel long. The flowers are red with a red to reddish-pink syle that has a green tip, the pistil long. Flowering occurs from August to October, and the fruit is a glabrous, narrowly oval follicle long.[1] [2]
Grevillea parallelinervis was first formally described in 1976 by John Carrick in Contributions from the Herbarium Australiense.[3]
This grevillea is found at the western end the Gawler Range between Yardea Station and Mount Wallaby, where it grows in shallow rocky soils in open shrubland.
