Umbels compound, primary umbel usually sessile on the crown of the plant, secondary lateral umbels with longer peduncles and shorter rays; bracts leaf-like; rays long, spreading to ascending; umbellules small; bracteoles linear-lanceolate, entire or sparingly lobed. Calyx teeth small, triangular. Petals obovate with acute inflexed tip. Stylopodium broad and slightly flattened; styles short, diverging in fruit. Fruit oblong-ovoid, mericarps weakly 5-winged.
