Holly leaf grevillea (Grevillea monticola)

Description

Grevillea is a diverse genus of about 360 species of evergreen flowering plants in the family Proteaceae, native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands east of the Wallace Line. It was named in honour of Charles Francis Greville. The species range from prostrate shrubs less than 50 cm (20 in) tall to trees 35 m (115 ft) tall. Common names include grevillea, spider flower, silky oak and toothbrush plant. Closely related to the genus Hakea, the genus gives its name to the subfamily Grevilleoideae. The brightly coloured, petal-less flowers consist of a calyx tube that splits into 4 lobes with long styles. They are good bird-attracting plants, honeyeaters in particular are common visitors. They are also used as food plants by the larvae of some Lepidoptera species including the dryandra moth and the Pieris rapae (small white). Grevillea aquifolium is a shrubby or scrambling plant endemic to South Australia and Victoria. Common names include holly grevillea, prickly grevillea or variable prickly grevillea. In occurs naturally in woodland, open forest and heathland. The height of the shrubby forms usually ranges between 1 and 2 metres, while prostrate forms are also observed in their natural distribution . The flowers occur in terminal one-sided racemes, typical of what are commonly referred to as "toothbrush" grevilleas. They are red or occasionally yellowish-green. Flowering in South Australia is recorded as being between November and March, while in the Grampians in Victoria it extends from September to April. The foliage is usually lobed with sharp points on the lobes.
