Trees or shrubs. Indument of short, straight, patent or appressed trichomes; glandular scales present on vegetative parts, inflorescence axes, pedicels, abaxial surface of calyx, pistil, and fruits; buds “varnished”. Leaves alternate, 1– 12-jugate; leaflets opposite to alternate, subsessile to petiolulate, margin entire to coarsely dentate. Inflorescences axillary or pseudo-terminal. Flowers zygomorphic or actinomorphic (in L. arcuata , L. brackenridgei , L. gracilipes , and L. lepidota ), functionally unisexual; sepals (4 –)5(– 6), free and imbricate or united (in L. arcuata , L. brackenridgei , L. gracilipes , and L. lepidota ) to form a dentate calyx cup; petals 5 (4 in L. glomeriflora ), with 2 distinct scales; disc lobed or not (in L. arcuata , L. brackenridgei , L. gracilipes , and L. lepidota ), rim glabrous to pilose; stamens (6–)8–9, anthers basifixed; ovary 2–3-locular. Fruit a capsule, with 2–3 well developed lobes, rarely 1 (in L. concolor , L. guillauminii , and L. samoensis ), dehiscence loculicidal, glabrous to puberulous and rugose to verrucose outside, glabrous to pilose inside; seed ellipsoid or ovoid to globose, sarcotesta covering half to all of the seed, flesh-membranaceous.
Distribution. – Lepidocupania comprises 21 species occurring in the Caroline Islands, Fiji, New Caledonia, Samoa, the Solomon Islands, and Vanuatu ( Fig. 4 View Fig ).
Notes. – Lepidocupania shares the presence of lepidote scales on its vegetative and reproductive organs with Lepiderema . However, Lepidocupania can easily be distinguished from Lepiderema by the presence (vs. absence) of petal and ovary scales, and it differs from Cupaniopsis by the presence (vs. absence) of glandular scales on its vegetative and fertile organs.
