Description
Phyllanthodendron can be readily morphologically distinguished from Glochidion, but recent molecular evidence showed that Phyllanthodendron is paraphyletic due to Glochidion being nested within it. In this study, a new species of the former Phyllanthodendron is described and illustrated as Glochidion yangchunense Z.Q. Song & Gang Yao from the limestone areas of South China. This is a peculiar new species and morphologically distinguished by its discoid flowers, T-shaped disc segments, and glabrous flowering branches. A key to Glochidion yangchunense and related species in China is provided here.
