报道宁夏石嘴山早二叠世一种矿化的孢子囊穗———中华盘穗Discinitessinensissp .nov.孢子叶表皮细胞长条形 ,两端尖 ;孢子囊为椭球体 ,基部收缩 ,呈短粗柄状 ;孢子囊壁及绒毡层细胞均纵向排列 ,不具环带 ;大、小孢子囊外形相似 ,不易区分 ,除非孢子囊破裂露出内部的孢子 .大、小原位孢子形态也相似 ,均为Deltoidospora类型 .该新种支持盘穗属于瓢叶目以及瓢叶目与前裸子植物的亲缘性 Reported a mineralized sporangium spores of Early Permian in Shizuishan, Ningxia, China --- Discinitessinensissp .nov. Spore leaf epidermal cells were strip-shaped with both ends pointed; the sporangium was ellipsoid, base contracted, Spore wall and tapetal cells were longitudinally arranged, not ring zone; large and small sporangia similar shape, not easy to distinguish, unless the sporangia burst internal spores. Large and small in situ spore morphology are also similar, are Deltoidospora species. This new species supports that the panicles belong to the order of the scutellum and the phylogenetic relationship of the sclerotinia to the former gymnosperms
