Styphelia is a genus of shrubs in the family Ericaceae, native from Indo-China through the Pacific to Australia. Most have minute or small leaves with a sharp tip, single, tube-shaped flowers arranged in leaf axils and with the ends of the petals rolled back with hairs in the inside of the tube.

Description

Plants in the genus Styphelia are usually erect or spreading shrubs that have egg-shaped, elliptical or oblong, more or less sessile leaves with many fine, almost parallel veins and a sharp point on the tip. The flowers are usually arranged singly in leaf axils with small bracts grading to larger bracteoles at the base and five, usually coloured sepals. The petals are fused to form a cylindrical tube with their tips rolled back. The inside of the petal tube is hairy and the five stamens and thread-like style extend beyond the end of the tube. The fruit is a drupe with a dry or slightly fleshy mesocarp and a hard endocarp.

Taxonomy and naming

The genus Styphelia was first formally described in 1793 by James Edward Smith in his book A Specimen of the Botany of New Holland. The name Styphelia is from an ancient Greek word meaning "tough" or "harsh", referring to the "stiff, prickly leaves and general habit" of the genus.
