Question: Why is Martynia annua excluded from the Proboscidea genus?

• Question

  Why is Martynia annua excluded from the Proboscidea genus?

  Answer

  The two genera you mention are different morphologically, as they differ in calyx and pollen morphology (among other features). But, your question should be switched around, why is Proboscidea excluded from Martynia. Martynia was the first named genus in the Martyniaceae, and it has priority before of its earlier publication date. So, barring any nomenclatural issues (e.g., conservation of a name, rejection of a name), if the two genera were found to be a single taxonomic unit, the name Martynia would be used (not Proboscidea). I hope this is useful to your study.
