Six Newly Recorded Species and One Newly Recorded Genus of Woody Plants in Sichuan Province, China

In this paper, six newly recorded species of woody plants in Sichuan Province were reported, namely Deutzia yunnanensis （Saxifragaceae）, Daphne brevituba （Thymelaeaceae）, Berberis taronensis （Berberidaceae）, Schefflera multinervia （Araliaceae）, Nothapodytes tomentosa （Icacinaceae） and Delavaya toxocarpa （Sapindaceae）. Delavaya toxocarpa belongs to the genus Delavaya Franch, which is a monophyletic species. According to relevant documentary records, it is distributed in Guangxi province and Yunnan province in China, and it is also distributed in northern Vietnam. The discovery in Huili city and Panzhihua city confirmed that it is a new genus record in Sichuan province. The voucher specimens were preserved in the Herbarium of Xichang college （XIAS）. The newly recorded discovery not only enriched the diversity of spermatophyte in Sichuan province, but also provided a basis for studying the origin, diffusion routes, and distribution of related groups.
