Kattungal Subramaniam Manilal (Malayalam: കാട്ടുങ്ങൽ സുബ്രഹ്മണ്യം മണിലാൽ) (born 17 September 1938) is an Emeritus of the University of Calicut, a botany scholar and taxonomist, who devoted over 35 years of his life to research, translation and annotation work of the Latin botanical treatise Hortus Malabaricus. This epic effort brought to light the main contents of the book, a wealth of botanical information on Malabar that had largely remained inaccessible to English-speaking scholars, because the entire text was in the Latin language.
