Notes:
The identity of this name is not entirely clear, and tracing it is problematic: this was based on a single specimen that was destroyed at B and known to us only as an image of a stem and three disarticulated leaves. The protologue describes the inflorescence and flowers in detail, though, so clearly more material was available to Schumann. He detailed the inflorescence as trichotomous with shortly pedunculate heads and bracts ca. 2 mm long, 4-5-merous flowers, a dentate calyx limb 1-2 mm long, a corolla ca. 6 mm long with short rounded lobes. The leaves are elliptic and robust, 14-35 x 3.5-10.5 cm, with an obtuse to rounded base and 13-15 pairs of secondary veins. The locality was given only as "Alto Amazonas". This name was synonymized with Simira rubescens by Steyermark 91972) and Barbosa & Peixoto (1989), but the leaves are unusually robust and the bracts unusually short for that species.
