摘要
剌参粉和江汉粉具有独特的萌发器和结构.依据结构形态,联系其出现的环境,分析了它们的结构和结构功能.从化石花粉与现生亲缘属花粉的差异,它们在上白垩统中出现的先后和形态结构的异、似情况,探讨了剌参粉的演化.概略地推测了刺参粉植物可能是从风媒植物到典型虫媒植物;由灌木到多年生草本植物;从生长于低山、丘陵到高山.描述了5新种.
Morinoipollenites and Jianghanpollis were established by Wang Daning and Zhao Yingniang in 1979, with unique apertures and structures. This paper expounds their structures and structural functions based on their morphology and palaeoenvironment, with exploration into the evolution of Morinoipollenites and the cause of its evolution based onthe diversity as compared with recent pollen species, the sequence of fossil, the difference and similarity in shape and structure. The parents of Morinoipollenizes might have evolved from anemophilous to entomophilous pollination, from bush to perennial herb and from living in lower mountains or hills to living in high mountains.
