Wood Anatomy of the Neotropical Sapotaceae. XXXVI. Syzygiopsis.

Abstract

Adolpho Ducke described the genus Syzygiopsis in 1925 but later (4)3/ changed his opinion and stated Barylucuma and Syzygiopsis which I had proposed on the basis of their opposite leaves cannot be maintained. The problem of placing these plants in good genera remained unsolved. Ducke's single species, Syzygiopsis oppositifolia, was transferred to Pouteria oppositifolia (Ducke) Baehni (2) in 1942. In 1946 Cronquist (3) described another species, Syzygiopsis sericea, with the qualifying statement In the absence of flowers, the generic position of this species cannot be determined with certainty, but the leaf veination is so similar to that of Syzygiopsis oppositifolia that I am convinced the two are congeneric. In 1957 van Royen (5) transferred Syzygiopsis oppositifolia to the Asiatic genus Planchonella making the new combination Planchonella oppositifolia (Ducke) van Royen. Aubreville (1) accepted Ducke's monotypic genus Syzygiopsis oppositifolia even though the floral structure was not distinguishable from several other genera of the Pouterieae because it was easy to identify by its opposite lanceolate leaves and distinctive nervation.
