Morphology Reproductive morphology Flowers
Flowers axillary, solitary or fasciculate or crowded towards the end of the branches.
Morphology Reproductive morphology Flowers Epicalyx
Epicalyx campanulate, deeply 5-lobed; bracts lanceolate, acute, striate towards the base.
Morphology Reproductive morphology Flowers Calyx
Calyx cupulate, deeply 5-fid; lobes ovate or ovate-lanceolate, 1-nerved and keeled.
Morphology Reproductive morphology Flowers Corolla
Petals rose-pink or mauve, stellate-pilose outside.
Morphology Reproductive morphology Flowers Androecium Stamens
Staminal tube equalling the petals, the lower portion dilated and united with the petals at the base; anthers subsessile.
Morphology Reproductive morphology Flowers Gynoecium Pistil

Staminal tube equalling the petals
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary of 5 free 1-ovulate carpels.
Morphology Reproductive morphology Flowers Gynoecium Style
Styles 10, reflexed, with discoid stigmas
Morphology Reproductive morphology Fruits
Fruits depressed globose, of 5 indehiscent trigonous mericarps, stellate-pubescent and with dense glochidiate spines dorsally (except in endemic Australian species), striate on the flat contiguous lateral surfaces.
Note
Formerly usually treated as a single species but apart from the pantropical species U. lobata with numerous varieties there are certainly three other distinct species in Australia (Craven & Fryxell in Austral. Syst. Bot. 2: 455–460 (1989)). One of these and several Indian species were transferred to Pavonia by Hochreutiner in 1901 but the latter may also be better considered as Urena again. Urena and Pavonia are extremely close and the former is the earlier name. It appears there are 4–6 species of true Urena.
