Leaf dissection

bipinnate: of leaves, twice pinnately divided. cf. pinnate, tripinnate.

palmatifid: of a leaf, deeply (but not completely) divided into several lobes which arise (almost) at the same level. cf. pinnatifid.

palmatisect: a condition intermediate between palmate and palmatifid, with the green tissue of the lamina completely divided into several segments, but the segments not fully separated at the base.

pinnatifid: cut deeply (but not to midrib) into lobes that are spaced out along the axis (of the leaf). cf. palmatifid, ternatifid.

pinnatisect: dissected down to the midrib but having the segments confluent with it.

plicate: folded back and forth longitudinally like a fan.

tripinnate: of leaves, thrice pinnately divided. cf. bipinnate, pinnate.
