Nifin'akanga

Commelina madagascarica is a monocotyledonous, herbaceous plant in the dayflower family, Commelinaceae, from Madagascar. It is commonly known as nifin'akanga there, where Wikipedia says it is used medicinally as an abortifacient, a galactogogue, and a treatment for conjunctivitis and acne. It is also used for ritual purposes in joro, or ancestral invocation, around the Lake Alaotra region. The plant has delicate, richly blue flowers, narrow leaves and bushy stems. Its roots are fibrous, fleshy and fusiform, and these, with the buried rhizome, make it very resistant to prairie fires. It was first described by Charles Baron Clarke in 1881 and is common on dry prairies and rocky ground between 1,500 and 2,000 metres above sea level. A Malagasy abortion-rights group takes its name from the plant.
