Leaves are opposite and petiolate, elliptic and lanceolate, with pinnate venation. Their margins may be entire, deeply lobed, cleft, crenate or dentate and petiolate with stipules. Leaves usually petiolate with distinct petiole and lamina, leaf arrangement distichous (spiral in Musaceae). The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. The alternate or rarely opposite leaves are petiolate or sessile, often persistent or tardily deciduous. Subpetiolate leaves are nearly petiolate, or have an extremely short petiole, and may appear sessile. The leaves are generally petiolate or subsessile, rarely sessile. The leaves may be petiolate or sessile. Petiolated leaves have a petiole (leaf stalk), and are said to be petiolate. The leaves are opposite, the upper leaves sessile and the lower leaves petiolate. The leaves are simple, flattened and may be sessile or short petiolate. The linear leaflets are ciliate and petiolate. The cauline leaves are much reduced and are short petiolate to sessile but not auriculate-clasping. Leaves oblong-elliptic, petiolate, often slightly mucronate. The petiolate leaves are dentate and often sticky.
