Merrill & L.M. Perry (1941: 125) . = Eugenia angustifolia Roxburgh (1832: 490) , nom. illeg., non Lamarck 1789 . = Jambosa polypetala Wallich (1840: 27) . = Eugenia polypetala (Wall.) Wight (1842: 8 . t. 610). Type citation:—‘A small tree, a native of Chittagong , where it flowers in March and April. The fruit ripens in June and July’. Lectotype (designated here): Icones Roxburgh Number 2135 (K!). Distribution:— India [Arunchal Pradesh, Assam , Meghalaya , Mizoram , Tripura , West Bengal ], Bangladesh and Myanmar . Notes:—Roxburgh’s name was illegitimate and Wallich’s Jambosa polypetala is a validly published replacement name. Merrill and Perry (1941), amongst others, were unaware of this and cited Wight as the earliest publication. As a result, the authorship is sometimes given as ‘Wall. ex Wight’, but this is incorrect. Since Wallich’s name is a nomen novum , it automatically takes the type of the replaced name, Roxburgh’s Eugenia angustifolia ( McNeill et al . 2012 , Article 7.4), and is not typified by either of the Wallich Catalogue Numbers (3616 & 1830) cited by Merrill and Perry.
