Synaphea quartzitica

Synaphea quartzitica is a small, tufted shrub or subshrub with several branched stems up to 7 cm (2.8 in) long with silky hairs, but covered by the leaf bases. The leaves are pinnatipartite with two or three pairs of lobes, 65–80 mm (2.6–3.1 in) long and 80–90 mm (3.1–3.5 in) wide on a petiole 60–180 mm (2.4–7.1 in) long. The primary lobes have three-parts 3–6 mm (0.12–0.24 in) wide, the end lobes triangular and sharply pointed. The flowers are yellow and borne in spikes 60–180 mm (2.4–7.1 in) long and about the same length as the leaves, on a branched, hairy, striated peduncle 20–100 mm (0.79–3.94 in) long. The bracts are ascending, 1–2 mm (0.039–0.079 in) long and broad. The perianth is spreading with a moderately wide opening, the upper tepal 4.5–5.0 mm (0.18–0.20 in) long and 1.5–2.0 mm (0.059–0.079 in) wide and strongly curved, the lower tepal 2.5–3.5 mm (0.098–0.138 in) long. The stigma is narrowly oblong and notched, 0.8–1.0 mm (0.031–0.039 in) long and 0.3–0.4 mm (0.012–0.016 in) wide, thick, straight to slightly s-shaped and the ovary is covered with soft hairs. Flowering occurs in July and August, and the fruit is narrowly oval, 4 mm (0.16 in) long and covered with soft hairs.

Quartz-loving synaphea is only known from four populations containg a total of less than 350 plants, growing on chert hills in open heath with Melaleuca radula and Kunzea species in the Moora-Watheroo area, in the Avon Wheatbelt and Geraldton Sandplains bioregions of Western Australia.
