Grevillea linearifolia f. h (Mt Buffalo form)

Grevillea alpivaga, also known as buffalo grevillea, is a species of flowering plant in the family Proteaceae and is endemic to a restricted area of Victoria, Australia. It is a shrub with crowded, linear leaves and pale green creamy-white flowers.

Description

Grevillea alpivaga is an erect to prostrate shrub that typically grows to a height of 0.7–1 mm (0.028–0.039 in) high and has ridged branchlets. Its leaves are crowded, linear, often curved, 8–25 mm (0.31–0.98 in) long and 0.8–1.4 mm (0.031–0.055 in) wide, the edges rolled downwards and the lower surface silky-hairy. The flowers are in sessile groups about 100 mm (3.9 in) long on the ends of branches and are pale green to creamy-white with a white to pink style. The perianth is silky-hairy on the outside, the pistil is 6.5–7 mm (0.26–0.28 in) long . Flowering mainly occurs from October to February and the fruit is slightly warty follicle about 9 mm (0.35 in) long.[3][4][5] This species is similar to G. gariwerdensis that has less crowded leaves and a pistil 7.0–8.5 mm (0.28–0.33 in) long, and to G. neurophylla subsp. neurophylla that has longer leaves with a convex upper surface.[5]

Taxonomy

Grevillea alpivaga was first formally described by French botanist Michel Gandoger in the Bulletin de la Société Botanique de France in 1919, from plant material collected from the Victorian Alps by Carl Walter.[6][7]

Distribution and habitat

Buffalo grevillea occurs in Eucalyptus woodland on granite and sandy soil on Mount Buffalo and towards Porepunkah.[4][5]

Conservation status

This grevillea is listed as "critically endangered" on the Flora and Fauna Guarantee Act 1988 Threatened Species List[1] and "rare in Victoria" on the Department of Sustainability and Environment's Advisory List of Rare Or Threatened Plants In Victoria.[8]
