A third described form, often called "D. binata" f. "multifida", has even more leaf divisions, bifurcating several times to produce anywhere from eight to 16 or even 30 terminal leaf points. This, too, was published by J. A. Mazrimas in the same 1976 volume of the "Carnivorous Plant Newsletter" as var. "multifida", referring to the description of a 27-point "D. binata" found by George Ashley and published in a 1975 volume of the "Carnivorous Plant Newsletter". Neither of these names were validly published, but again they remain in use among carnivorous plant growers. A final form, known for producing up to 40 terminal leaf points, is frequently titled f. "extrema", another name that has never been validly published but remains in use.
