A New Combination in Senecio (Asteraceae) from South America
The name Senecio grisebachii Baker var. schyzotus Cabrera is recognized at the specific rank, and accordingly, a new combination, i.e., S. schyzotus (Cabrera) Iamonico, is proposed. This species differs from S. pterophorus DC. (= S. grisebachii) in having leaf bases with laciniate auricles.
