Taxonomy
The type of Phanera bicornuta Miq. (U) consists of two sterile branches, some loose leaves, a loose pod and one seed. This specimen was treated by De Wit under Phanera bidentata as subsp. bicornuta. Nothing in the material, however, suggests that this specimen belongs there; most certainly it belongs to Bauhinia integrifolia, even Miquel writes in the protologue that it is close to Phanera polyantha (= Bauhinia integrifolia).
