Synonyms: Keraudrenia APNI*
Description: Tall shrubs. Juvenile growth, especially post-fire, has trilobed, larger leaves with undulate, mainly serrate margins and larger flowers than do the mature plants.
Leaves simple, toothed.
Inflorescence of dense, leaf-opposed or terminal cymes. Calyx deeply 5-lobed, scarcely enlarged in fruit. Petals absent. Stamens 5, alternating with the sepals; staminodes 5, slightly united with the stamens at the base. Ovary sessile, tomentose, 5-locular, with 2 or 3 ovules in each loculus; styles fused. Carpels c. as long as the sepals.
carpels free in fruit, densely pubescent, with a short, wide truncate wing on the back.
Distribution and occurrence: World 20 spp., Australia and Madagascar. Australia 19 spp., WA, NT, Qld, NSW, SA. Harden in Flora of NSW Vol 1 included New Guinea in the distribution of Seringia (and of ,Keraudrenia, now included in Seringia). This is not supported by herbarium collections in Australia or internationally (Wilkins & Whitlock, Australian Systematic Botany 28: 265–325, 2016).
