福建分布新记录沙梨木及其叶片的显微鉴别

New Distribution Record of Crateva magna in Fujian Province and Microscopic Identification of Leaf

    摘要
  • 摘要: 报道了2021 年10 月19 日在福建省发现的山柑科Capparaceae 鱼木属Crateva 植物沙梨木C. magna （Loureiro）DC，为福建分布新记录。本种与同属植物树头菜C. unilocularis Buch.-Ham.较为相似，不同之处在于： 该种叶片卵状披针形至长圆状披针形；花干后黄白色；萼片披针形较窄；果实椭圆形至长圆状卵形，种子压扁， 背部有明显的瘤状刺。对沙梨木叶进行显微观察，为沙梨木的进一步研究提供参考资料。凭证标本保存于福建师 范大学生命科学学院植物标本馆（FNU）。

     

    Abstract: On October 19th 2021, Crateva magna, a new record species of Crateva L. from Capparaceae was found in Fuzhou, Fujian province. It is similar to C. unilocularis, but leaf of C. magna is ovate-lanceolate to oblong-lanceolate, with flower of yellowish-white after drying. The sepals were narrower than lanceolate, fruit oval to oblong-ovate, seeds flattened, and obvious tumor-like spines on the back. Microexamination was implemented on C. magna leaf leaves. Voucher specimens were conserved in Plant Herbarium of College of Life Sciences, Fujian Normal University ( FNU).
