Botanical Description

Ranunculus ternatus is a small tuberous perennial herb in the Ranunculaceae, native to grassy fields, ditch banks, and damp slopes across central and southern China, Japan, and Korea. From a cluster of small, spindle-shaped to ovoid fleshy tubers 5-15 mm long arises a low rosette of long-petiolate basal leaves that are simple to ternately compound, with three obovate to broadly cuneate leaflets that are shallowly three-lobed or coarsely toothed at the apex, dark green and glabrous to sparsely hairy. One to a few slender flowering stems 5-20 cm tall bear small bright yellow five-petalled flowers about 8-10 mm across with numerous stamens and a domed receptacle. Fruits are small ovoid achenes aggregated into a head. The dried tuberous roots, dug in spring, are the medicinal Mao Zhao Cao.
