On embryo polarity, polycotyly, and the homology test of conjunction: A reply to Kuijt´s (2017) critique

  • Favio González
  • Natalia Pabón-Mora

In a recent paper, we presented detailed morphoanatomical evidence clarifying that what has been interpreted as a polycotyledonous embryo in Psittacanthus actually corresponds to the endosperm, and that the seedlings are typically dicotyledonous (González & Pabón-Mora, 2017). This paper has been criticized by Kuijt (2017, this issue), who has consistently (Kuijt, 1967, 1970, 1973, 2015) upheld the occurrence of polycotyly and concurrent lack of endosperm (hereafter PCLoE), an interpretation dating back to Eichler (1868). Kuijt’s critique, lacking significant new empirical data, is based on the assumption that our results contain taxonomic misidentification, seedling misinterpretation, and biased interpretation of the literature. Here we reply one by one to the issues raised in his rebuttal.

First, there is no such taxonomic misidentification of Struthanthus and Psittacanthusseedlings in our Fig. 3. In addition to the samples used to reconstruct Fig. 3, we have further examined 80+...
