This paper describes the fossil fruits of Scirpus weichangensis X.Q. Liang, sp. nov. from the early Miocene of Guangyongfa Village, Weichang County, Hebei Province, North China. The fossil fruits are obovate in shape and their lateral sections are plumply trigonous. The cell walls of the surface are straight. The persistent stout bristles have downward-directed barbellae in distal 1/2. The occurrence of the fossil Scirpus indicates that Guangfayong was a wetland in the early Miocene. Based on the fossil data, the genus likely originated in Western Siberia in the Oligocene, spread during the Miocene, and was finally distributed worldwide in the Holocene.

华北河北省围场早中新世雪松（莎草科）果实及其古生态和古生物地理意义

本文描述了 Scirpus weichangensis XQ Liang, sp. 的化石果实。十一月 产于华北河北省围场县广永发村早中新世。化石果实呈倒卵形，侧面呈丰满的三棱形。表面的细胞壁是直的。持久的粗硬刷毛在远端 1/2 处有向下的须须。Scirpus化石的出现表明广发永是中新世早期的湿地。根据化石资料，该属很可能在渐新世起源于西西伯利亚，在中新世传播，最终在全新世分布于世界各地。
