  • Family

    Menispermaceae

  • Scientific Name

    Odontocarya micrantha (Diels) Barneby

  • Description

    Distribution and Ecology - BRAZIL: Amazonas: Bom Fim, rio Jurua, fl [male] in Oct 1900, Ule 5014 (B, holotype, G, isotype).

  • Discussion

    Study of two sheets of the type-collection, previously known to me only from Field Museum Negative 5002, confirm the transfer from Disciphania to Odontocarya. Nigrescent foliage, reflexed bracts along the main axis of the staminate inflorescence, and dilated filaments certainly suggest Disciphania, but the fasciculate and pedicellate flowers with a hexamerous androecium are characters of Odontocarya. A striking feature, not shown in the phototype but evident in the actual specimens, is the presence of leaf-nectaries between the main nerves as they converge at the petiole. Nectaries (or domatia) of this type are known in Odontocarya tamoides and O. tripetala, but in no Disciphania
