Abstract

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.

Glochidion yangchunense (Phyllanthaceae)，中国广东省的盘状花新种

Phyllanthodendron 在形态上很容易与 Glochidion 区分开来，但最近的分子证据表明，由于 Glochidion 嵌套在 Phyllanthodendron 中，因此 Phyllanthodendron 属于旁系。在本研究中，描述并图解了产自华南石灰岩地区的前 Phyllanthodendron 的一个新种，即 Glochidion yangchunense Z.Q. Song & Gang Yao。这是一个奇特的新种，在形态上以其盘状花、T 形花盘裂片和无毛花枝而与众不同。这里提供了 Glochidion yangchunense 及中国相关种的检索表。
