Chamelaucieae

Rock thryptomene Thryptomene saxicola, photographed by Brian Walters.

Belongs within: Myrtaceae.
Contains: Verticordia.

The Chamelaucieae are a group of mostly smooth-leaved plants bearing dry fruits. Historically, the group has been recognised as including Myrtaceae with dry but indehiscent fruits, but molecular analyses support the inclusion of genera with capsular fruits such as Baeckea (Wilson et al. 2005). The type genus, Chamelaucium, is native to south-western Australia; the Geraldton wax C. uncinatum is cultivated as an ornamental. Darwinia species bear flowers in pairs or in compound heads, sometimes surrounded by leafy bracts.

Characters (from Wilson et al. 2005): Shrubs, mostly glabrous. Leaves opposite, less commonly spiral. Inflorescences mostly of solitary flowers but sometimes forming corymb-like confloresences; stamens usually few, mostly free but occasionally in clusters opposite the sepals, staminodes present in a few genera; anthers usually adnate, rarely versatile, dehiscing by slits or pores. Ovary inferior 1- to 3-locular; ovules anatropous or hemitropous. Fruit a capsule, or indehiscent; seeds reniform or ovoid to linear; embryo with very small cotyledons on a slender neck appressed to a relatively massive hypocotyl.
