Original diagnosis/description

Leaf small, semicoriaceous in texture, rounded and truncate at the base, three-lobed, the central lobe apparently much the longest and strongest (broken), lateral lobes short, acute, at an angle of about 45°; nervation obscure, except for the very strong midrib and the much lighter lateral ribs. which arise near the base of the blade. This little leaf, the only one seen in the collection, has the basal portion well preserved, but the evidently large central lobe is broken. The distance between the tips of the lateral lobes is about 3.5 centimeters.
