Categorized under "General"

Definition as written by spklatt:

A leaf that has leaflets arranged on side branches off its main axis.

Bipinnate is one of several types of compound leaves - i.e. leaves that have many leaflets. Two other examples are palmate and trifoliate.

Definition as written by palmbob:

Since pinnate means leaflets coming off a central rachis in a somewhat feather-like pattern, binnate refers leaflets arrising of the \'secondary petioles\' also in a feather-like pattern. This is a Caryota leaf showing a binnate pattern- this is the only genus of palms that is bipinnate- all the rest are either pinnate, palmate or some \'hybrid\' of the two.
