Grevillea patentiloba

Grevillea patentiloba is a prostrate to erect, spreading to straggling shrub that typically grows to a height of 0.3–3 m (1 ft 0 in – 9 ft 10 in). Its leaves are 15–50 mm (0.59–1.97 in) long and 15–65 mm (0.59–2.56 in) wide in outline, and pinnatisect to pinnatipartite or pinnatifid with 3 to 7 lobes widely spreading lobes, usually divided again, the end lobes linear to oblong or triangular and sharply pointed, 3–20 mm (0.12–0.79 in) long and 1–9 mm (0.039–0.354 in) wide. The edges of the lobes are turned down or rolled under, enclosing most of the lower surface. The flowers are arranged in down-turned clusters of 2 to 10 flowers on a silky-hairy rachis 1–5 mm (0.039–0.197 in) long, the pistil 15–20 mm (0.59–0.79 in) long. The flowers are red to deep pink and cream-coloured to bright yellow, the style red to deep pink. Flowering time depends on subspecies and the fruit is a glabrous follicle 10–14 mm (0.39–0.55 in) long.[2][3]

Grevillea patentiloba was first formally described in 1859 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae.[4][5] The specific epithet (patentiloba) means "spreading-lobed", referring to the leaves.[6]

In 1994, Peter Olde and Neil Marriott described two subspecies of G. patentiloba in The Grevillea Book, and the names are accepted by the Australian Plant Census:

• Grevillea patentiloba F.Muell. subsp. patentiloba[7] is a prostrate to low, spreading shrub usually less than 1 m (3 ft 3 in) high that flowers from June to November.[8][9]
• Grevillea patentiloba subsp. platypoda (F.Muell.) Olde & Marriott[10] is a robust, more or less upright shrub usually 1.5–3 m (4 ft 11 in – 9 ft 10 in) high that flowers from July to November.[11][12]

Subspecies patentiloba grows in heath and scrubby woodland from near Lake King to Hopetoun and near Ravensthorpe in the Esperance Plains and Mallee bioregions of south-western Western Australia and subspecies platyloba grows in open woodland and shrubland in the Ravensthorpe area in the Esperance Plains bioregion.[8][9][11][12]

Both subspecies of G. patentiloba are listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[8][11]
