Nomenclature Exercise:  Naming a Sunflower

The following names have been published for a small weedy perennial of the southwestern United States. Names with the same specific epithet are based on the same holotype.

The following names have been validly published for unrelated species:

1.  What is the correct name for this plant if, in your taxonomic opinion, it belongs in the genus:

  1. Aster
  2. Leucelene

2.  For each, indicate why the synonyms are invalid (i.e., taxonomic synonym, nomenclatural synonym, homonym, tautonym).
