Lasia is a genus of flowering plants in the family Araceae, native to Asia and New Guinea. The genus contains only two known species, Lasia spinosa and Lasia concinna.[1][2][3] Lasia was believed to be a monotypic genus until 1997 when a wild population of Lasia concinna was discovered in a farmer's paddy field in West Kalimantan,, Indonesia. The farmer had been growing them for their edible young leaves. This species of Lasia had been known of previously only from a single specimen at the Bogor Botanic Gardens, formally described in 1920.[4] Prior to 1997, the specimen was believed to have been a hybrid between Lasia spinosa and Cyrtosperma merkusii.[5] The subsequent discovery by Hambali and Sizemore led to the realization that it was in fact a distinct species.[6][7]

In Sri Lanka, Lasia spinosa is known as Kohila (කොහිල) and the leaves and rhizomes of the plant are used in Sri Lankan cuisine.[8]
