Evaluation of the species boundaries between Parthenium hysterophorus and P. glomeratum (Asteraceae-Ambrosiinae): morphological, anatomical, chromosomal and phytochemical evidence

Species boundaries between Parthenium hysterophorus L./P. glomeratum Rollins were examined. Our working hypothesis states that the delimitation of these taxa is based on the dissection of a continuous variation pattern from an elevational cline. We chose a 70 km gradient from 300-3500 m in the Provi...
