pinnately compound leaf
A leaf which is divided into smaller leaflets, those leaflets arranged on each side of the leaf's central stalk/rachis (axis). A pinnate leaf can either be even-pinnate or odd-pinnate, indicating whether or not a terminal leaflet exists: even-pinnate leaves have pairs of leaflets attached along the leaf's central stalk/rachis (axis) with no terminal leaflet, although may occasionally have a tendril (therefore an even number of leaflets in total); odd-pinnate leaves have a terminal leaflet at the end of the leaf's central stalk/rachis (axis) along with pair(s) of leaflets attached along the leaf's rachis (therefore and odd number of leaflets in total). A bipinnately compound leaf is twice pinnate; a leaf blade divided into leaflets and having twice-diverged branching.
