Mitrephora winitii

Mitrephora winitii is a species of plant in the family Annonaceae. It is native to Thailand.[1] William Grant Craib, the British botanist who first formally described the species, named it after Phya Winit Wanandor, the Thai botanist who collected the specimen that Robinson examined.[2] In the Prachuap Khiri Khan province of Thailand it is commonly referred to as Mahaphrom.
