Stems and leaves
Branches with light brown bark and visible leaf scars; inner bark light yellow and slightly bitter; twigs become brown with light brown dots (lenticels - small, oval, rounded spots upon the stem or branch of a plant, from which the underlying tissues may protrude or roots may issue).[5]
Thin, simple, alternate leaves[9] occur singly,[5] 5 centimetres (2.0 in) to 17 centimetres (6.7 in) long and 2 centimetres (0.79 in)[8] to 6 centimetres (2.4 in) wide;[5] rounded at the base and pointed at the tip (oblong-lanceolate).[8] Pale green on both surfaces and mostly hairless[5] with slight hairs on the underside when young.[6] The sides sometimes are slightly unequal and the leaf edges are without teeth, inconspicuously hairy when young.[5][9]
Leaf stalks are 0.4 centimetres (0.16 in) to 2.2 centimetres (0.87 in)[8] long, green, sparsely pubescent[5]
