It states that d. binata multifida has from six to eight leaf divisions (points) per leaf whereas d. binata multifida extrema can have over thirty leaf divisions. The plant that I have has eight divisions, though I thought it was an "extrema"...I have one mother plant that is recovering from some *very* hard times, it probably has a half dozen smallish leaves at the moment. The other binatas are yearling plants started from leaf cuttings from the mother plant and have leaves roughly five to six inches wide and with eight points. Could these plants, as they grow and as the mother plant regains its size, put on more than the current eight leaf divisions to warrant the "extrema" suffix? Here's a (not exactly great) picture of a clone of the mother plant.
