Grevillea thelemanniana

Grevillea thelemanniana is a spreading shrub that typically grows to 0.5–1 m (1 ft 8 in – 3 ft 3 in) high and 1–2.5 m (3 ft 3 in – 8 ft 2 in) or more wide. Its leaves are linear and pinnatipartite to pinnatisect, 25–45 mm (0.98–1.77 in) long with 2 to 5 lobes, the end lobes of the divided leaves 2–8 mm (0.079–0.315 in) long, the linear leaves and the end lobes of the divided leaves are 1.0–1.5 mm (0.039–0.059 in) wide. The upper surface of the leaves is more or less glabrous, the edges of the leaves are down-curved or rolled under, and the lower surface is silky-hairy. The flowers are borne in cylindrical clusters of 6 to 14 on one side of a raceme 5–15 mm (0.20–0.59 in) long. The flowers are pinkish red and cream-coloured, the style red with a green tip, and the pistil is 24–28 mm (0.94–1.10 in) long. Flowering occurs from July to October and the fruit is an oblong to elliptic follicle 12–13 mm (0.47–0.51 in) long.[2][3][4]

Grevillea thelemanniana was first formally described in 1839 by Stephan Endlicher in Novarum Stirpium Decades, from an unpublished description by Charles von Hügel.[5][6] The specific epithet (thelemanniana) honours C. Thelemann, a Viennese gardener.[4][7]

Spider net grevillea grows in winter-wet swampy heath in the Cannington, Kenwick and Wattle Grove suburbs of Perth, Western Australia.[2][3]

Grevillea thelemanniana is listed as "critically endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[2] meaning that it is in danger of extinction.[8]
