Viola lilliputana, the Lilliputian violet, is a species of violet described in 2012, and is among the smallest violets, and in fact one of the tiniest terrestrial dicot plants in the world. It was discovered from the arid puna in the Peruvian Andes in 1960s and formally described only after half a century later. The name is derived from the fictional little people in Gulliver's Travels. The violet species was selected by the International Institute for Species Exploration at Arizona State University to be among the Top 10 New Species discovered in 2012 out of more than 140 nominated species.
