(1840: 149) var. oblongifolia Meisn. (1855: 50) Type (designated by Brandbyge 1986 ) :— BRAZIL . Pará State, Playa de Jurupari, on the banks of the Amazon River, Martius 2841 ( lectotype : M ). Notes:— The protologue lists the type locality as “in ripa flum. Amazonum, e.g. ad Praya de Jurupari, prov. Paraënsis, nec non ad flum. S . Francisci (?)”. We were unable to locate a “Praya de Jurupari” [“Praya” could be a typo, and “playa” (= beach) was intended, or it could be a phonetic spelling of “praia”]. There are three “Ilha Jurupari” on the Amazon River, one in the State of Pará and two are in the neighboring State of Amazonas. Of these two latter islands, the nearest one to the boarder of the state of Pará is over 1000 km upriver. As a result, the type locality is most likely the beaches of the Ilha Jurupari in Pará. Brandbyge (1986) designated the lectotype at M but did not mention any other specimens. We found one specimen at NY ( NY 324255) which is labeled as Triplaris martiana var. oblongifolia Meisn. and filed as a "possible type”. As reported below (in our treatment of T. pachau Mart. ex Meisn. ), this NY specimen better fits the protologue information for T. pachau species and, as a result, should be considered as type material for it.
