Dracophyllum
Labill.Glabrous shrubs or small trees; branchlets often with prominent annular scars from fallen leaves. Leaves completely sheathing stems at base, usually concolorous, parallel-veined. Flowers bisexual, glabrous, solitary, or in racemes, spikes or panicles; individual flowers subtended by 1–several persistent or caducous bracts and bracteoles; pedicels shorter than to longer than calyx; calyx 5-lobed, persistent, shorter to longer than corolla tube; corolla ovoid, ellipsoid or conical, 5-lobed, sometimes closed at apex and not separating into lobes but splitting transversely near the base, the upper part (operculum) shed, the lower cup-like part persisting, white, yellowish to pink or dark red; stamens 5, free from corolla; filaments inserted at base of ovary, often persistent until fruiting; nectary of 5 indistinct scales, rarely united into a ring; ovary 5-locular, with many ovules per locule, style filiform, inserted in a depression at ovary apex. Fruit a loculicidal, 5-valved capsule; seeds numerous, small with reticulate testa.
A genus of ca. 60 species in the western Pacific; also New Caledonia, New Zealand. In Australia also in Queensland, New South Wales (including Lord Howe Island) and Tasmania.
Several Australian (including both Victorian) species were recognised as the distinct genus Richea, distinguished by the corolla remaining closed and shed entire as an operculum. Venter (2021) following DNA analysis by Wagstaff et al. (2010), included Richea in an expanded Dracophyllum and erected 2 subgenera (Richea and Cystanthe) to accommodate species formerly in Richea. Both Victorian species belong to subgenus Richea.
