Ruellia inundata is a subshrub plant, in the genus Ruellia, family Acanthaceae and is a perennial herbaceous plant first described by the German botanist Carl Sigismund Kunth.

A plant whose distribution occurs in North and South America, especially in the regions of Mexico, Colombia and Brazil is not endemic to its germination.[1]

Description

This plant features erect or sometimes trailing stems. Its leaves are held on short stalks, less than two inches long, and have a soft, hairy texture. The leaf itself can be oval, egg-shaped, or broader at the tip, tapering to either a pointed or rounded base.

It produces clusters of pink flowers that emerge from the leaf axils, each cluster accompanied by small, leafy bracts. The flowers have a distinctive shape: a narrow tube that flares open into a wider, trumpet-like bell, with the petals often curling backwards. The stamens are tucked neatly inside the flower and do not protrude.

The fruit is a unique, club-shaped capsule that, when ripe, splits open to release its seeds—up to four per pod—while the central core remains intact.[2][3]

The inflorescence consists of branches, consisting of dense, capitate clusters. The fruits are dry, club-shaped, up to 1 cm long. Flowering: November-June.[4]
