Ruellia brevifolia

This slideshow requires JavaScript.

A common species of a large chunk of tropical South America. Widespread. Emblematic of the pedunculate species in the “Physiruellia” clade. In the second photo, note the woody capsule (fruit) with modified funiculi (hooks) that aid in seed dispersal when the fruit explodes, as all Acanths in the proper sense do.
