Discussion:The fruiting specimens collected by Williams were originally identified as Alibertia obidensis Huber by Standley. They are definitely not to be identified with that genus. They are placed in the present treatment with Stachyarrhena, and appear to have the same type of leaf shape and suborbicular stipule truncate at the apex which are present in the staminate material of S. penduliflora, with which species they are provisionally identified.
