Florae Malesianae Precursores XVII. Notes on Malaysian and some S.E. Asian Cyperaceae V

Mapania holttumii Kern, nom. nov. — Mapania insignis Holttum, Gard. Bull. Sing. 11, 1947, 293, non Sandwith, Kew Bull. 1933, 496. When publishing the name Mapania insignis for a species occurring in the Malay Peninsula, Holttum overlooked the existence of the earlier homonym Mapania insignis Sandw. for a different species from British Guyana. I therefore propose to replace the illegitimate binomial by that of Mapania holttumii.
