Borreria latifolia var y minor Schum., Mart. Fl. Bras. 6(6): 61. 1888.
This small-leaved variation is usually found on prostrate plants. The stems vary from glabrate to densely pilose, as do also the lower and upper leaf surfaces. The lateral nerves are usually 4-5 on each side of the leaf blades, these varying from ovate to lance-elliptic, 1-3 × 0.5-1.7 cm, usually shortly acute at the apex, cuneate at the base, and sessile to 3 mm long petiolate. In forma fockeana the main cauline leaves are developed to a greater size than in forma minor, but specimens are found which show intergradation in leaf size.
