Belongs within: Styphelioideae.
The Styphelieae are a group of ericaceous shrubs with fleshy fruits. In the Australasian genus Pentachondra, the fruits are divided into usually five separate pyrenes whereas fruits of most other genera are five-loculed with a bony endocarp. Cyathodes have flower pedicels bearing many, more or less persistent bracts and a corolla that is more or less glabrous on the upper surface whereas Leucopogon flowers have fewer, caducous bracts on the pedicel and a bearded upper surface on the corolla (Allan 1961). Styphelia bears flowers with anthers on long filaments that are well exserted from the corollar tube. Astroloma bears long, tubular flowers that usually bear tufts of hairs or ciliated scales inside the corolla.
Characters (from Kron et al. 2002): Shrubs. Leaves alternate, entire, with leaf base narrow and one to several longitudinal veins having abaxial fiber cap that contacts abaxial epidermis. Flowers in terminal or reduced axillary racemes; bracts several grading upward in size, or one, mostly small and persistent, sometimes leaflike and caducous; bracteoles 2. Flowers 5-merous. Calyx lobes ciliate, persistent; corolla sympetalous, cylindrical, the lobes straight, spreading or recurved, mostly valvate in bud, occasionally imbricate. Stamens 5, epipetalous; anthers monothecal, with or without appendages. Pollen in monads, sometimes in tetrads or shed as reduced tetrads with one or more cells aborting. Ovary 2–11-locular, each with single ovule, placentation apical, style not impressed. Fruit drupaceous and brightly coloured, sometimes splitting to release endocarp, with sometimes splits into separate pyrenes.
