About Hibbertia mucronata (Turcz.) Benth.
Hibbertia mucronata (Turcz.) Benth. is a shrub that typically grows up to one metre (three feet three inches) tall, and has branchlets covered in woolly hairs. Its leaves are crowded, spirally arranged, thick, and linear, tapering to a sharp point. Each leaf is 5 to 18 millimetres long, 0.9 to 1.5 millimetres wide, and grows from a petiole 1.0 to 1.5 millimetres long. Flowers are arranged singly in leaf axils. They are more or less sessile, or sit on a hairy peduncle up to two millimetres long, and sometimes have sharply-pointed bracts at their base. This species has five sepals joined at the base: outer sepals are 6.0 to 8.5 millimetres long, while inner sepals are 5 to 5.5 millimetres long. The five petals are golden yellow, egg-shaped with the narrower end at the base, 6 to 9 millimetres long, and have a notch at the tip. There are five stamens, fused at the base on one side of the two densely hairy carpels, and each carpel holds two ovules. Flowering occurs mostly between August and December. This species grows in rocky sites, sandy heath, or mallee-scrub. It is found in the south of Western Australia, from Fitzgerald River National Park eastward to Ravensthorpe and Hopetoun.
