A rebuttal to a recent article by González and Pabón-Mora (2017) claiming the absence of polycotyly and the presence of endosperm in Psittacanthus (Loranthaceae)

  • Job Kuijt


The claim by González & Pabón-Moran (Brittonia 69: 176–185, 2017) that Psittacanthus (Loranthaceae) lacks polycotyly but has endosperm is shown to be based both on taxonomic misidentification and misinterpretation of seedling structure. The absence of endosperm and the presence of polycotyly in some species has been abundantly confirmed in the literature, much of the contents of which is ignored by González & Pabón-Moran.
