Grevillea angustiloba

Grevillea angustiloba is a prostrate to low-lying or erect shrub that grows up to 0.3–2 m (1 ft 0 in – 6 ft 7 in) high, 3 m (9.8 ft) wide and has hairy stems. The leaves are 35–117 mm (1.4–4.6 in) long and 19–110 mm (0.75–4.33 in) wide in outline, deeply divided, pinnate or bipinnate with up to thirty lobes, the end lobes mostly linear, 7–42 mm (0.28–1.65 in) long and 1–4 mm (0.039–0.157 in) wide. The flowers are arranged along an erect rachis 20–50 mm (0.79–1.97 in) long, and are red, sometimes orange or pale yellow, the pistil 19.5–25 mm (0.768–0.984 in) long, usually with a pink to red style. Flowering mainly occurs from February to March and the fruit is a follicle 11–16 mm (0.43–0.63 in) long.^[4]

Dissected holly-leaf grevillea was first formally described in 1868 by Ferdinand von Mueller, as Grevillea ilicifolia var. angustiloba in his Fragmenta Phytographiae Australiae.^[5][6]

In 2004, Trisha L. Downing, Marco Duretto and Pauline Ladiges raised the variety to species status as G. angustiloba and described two subspecies in Australian Systematic Botany. These subspecies are accepted by the Australian Plant Census:

• G. angustiloba (F.Muell.) Downing subsp. angustiloba^[7] has leaf lobes 2–4 mm (0.079–0.157 in) wide;^[8]
• G. angustiloba subsp. wirregaensis Downing^[9] has leaf lobes mostly 1.0–1.5 mm (0.039–0.059 in) wide.^[10]
