Description

Boronia yarrowmerensis is an erect, woody shrub that typically grows to a height of about 0.5 m (1 ft 8 in). It has pinnate or bipinnate leaves 21–35 mm (0.83–1.38 in) long and 24–44 mm (0.94–1.73 in) wide with between three and seven leaflets on a petiole 5.5–13 mm (0.22–0.51 in) long. The end leaflet is linear, 5–17 mm (0.20–0.67 in) long and about 1 mm (0.039 in) wide and the side leaflets are similar but longer. The flowers are white and are arranged in groups of up to seven in leaf axils on a peduncle about 1 mm (0.039 in) long. The sepals are circular, about 1 mm (0.039 in) long and wide and the petals are 2–2.5 mm (0.079–0.098 in) long. The stamens and the style are hairy and the stigma is minute, scarcely wider than the style. Flowering has been observed in October and the fruit is a glabrous capsule about 3 mm (0.12 in) long and 1.5 mm (0.059 in) wide.[2][3]
