Description
This species occurs in mountains (rarely coast) of south-eastern New South Wales, south from Bathurst, and in eastern Victoria, east and north from Wilsons Promontory. This form is originated from Mt Tamboritha, Victoria. It grows in various habitats, usually moist sites near water, including riparian scrub associations, open snow-gum woodland, and tall eucalypt forest, in sandy, gravelly or light clay soils over granite, sandstone, serpentine or limestone. The specific epithet alludes to the hairy branchlets and leaves and is derived from the Latin lana (wool) and -ger, (bearing).
Botanical Description
It is a prostrate to mounded or dense erect shrub 0.2-2m tall. The branchlets are more or less terete, pubescent to villous, thin or stout.

The leaves are entire, narrowly oblong-elliptic to narrowly obovate or sublinear, sometimes plumply subterete, 0.5-4cm long, 1-5mm wide. The margins are revolute to recurved. The upper surface is scabrid and sometimes villous. The lower surface is enclosed and then 1-grooved or exposed and then villous to sublanate.

The conflorescence is terminal and/or upper-axillary, usually simple, decurved or erect, usually a subsecund cluster, 2-10-flowered, basipetal. The floral rachis is 2.5-10mm long, almost glabrous. The flowers are acroscopic. The perianth is pale pink to red at base and cream above, or red or cream throughout, rarely cream-green or pale yellow. The style is pink to red or rarely yellow-green. The perianth is glabrous outside, bearded inside. The pistil is 13.5-19.5mm long. The ovary is subsessile (stipe < 1mm long), villous. The style is dorsally loosely tomentose to villous except near apex, weakly to moderately exserted from late bud. The pollen-presenter is lateral.

The follicle is ellipsoidal to narrowly ovoid, 10-15mm long, loosely villous, faintly ridged.

It is related to Grevillea rosmarinifolia, which has a glabrous ovary and style and a dense tuft of hairs on the stipe just below the ovary.
Member of
The Genus: Grevillea Section: Floribunda Subsection: Rosmarinifolia having the following characters: Leaf lower surface exposed or enclosed, hairy or glabrous. Flowers with perianth glabrous or sometimes hairy outside, hairy inside; late bud with limb obtuse; tepals lacking ridges and terminal apiculation; apical limb-segments of tepals usually lacking a strong median ridge or keel. Nectary arcuate to U-shaped or rarely cushion-like, margin usually smooth. Pistil 9–29 mm long; ovary shortly stipitate to subsessile, glabrous or almost so to densely villous; stipe sometimes swollen and hairy; style exserted strongly to weakly from late bud, or sometimes dorsally exposed but not exserted; style-end not apiculate. Follicle smooth to ridged; style persistent, erect, not deflexed.

A group of six species in south-eastern N.S.W. and Vic. Primarily bird-pollinated.
Useful plant
It is very popular with honey-eating birds and is extremely useful in landscaping in all climates, especially prostrate forms. They are useful for groundcover, general planting, screening and low windbreaks and are most suitable for coastal exposure.

Sowing instructions
SPRING Keep in refrigerator at 39°F in dry condition. Scarify the seed coating. Soak the seeds in warm water of 140°F for 48h with a SmokeDisk. Sow the seeds at 10mm depth in the Well Drained Seed Sowing Mix between 64-72°F. During germination keep the substrate moist and in daylight. The seeds germinate in 2-12 weeks. The viability of the seeds, kept under good conditions, is 5 years.

Cuttings instructions
Take the cuttings in early fall. Soak them in a hormonal preparation for cuttings before planting them in a substrate composed of 50% perlite and 50% heather earth. Keep them sufficiently moist at a temperature of 20°C in sealed freezer bags. Keep the light on for 16 hours a day.
