摘要
皱体双囊粉是低海拔山地针叶树植物的花粉。我国的皱体双囊粉自早三叠世开始出现，白垩纪是它的发展时期，晚白垩世赛诺期是它的鼎盛期。白垩纪末皱体双囊粉基本灭绝，仅有少数种的个别分子孑遗到古新世、始新世，甚至中新世。干旱一半干旱亚热带气候控制下的低山丘陵地最适宜其生长。该属有近２７种，依据气囊与本体的着生关系及其相对大小分成双束松、单束松、雪松、云杉和罗汉松型五个组，再结合帽上的纹饰、发育程度来区分。笔者编写了种的检索，并对１４新种和一些老种作了详细描述．
As the pollen of coniferophyte in low-lying mountain areas Rugubivesiculites in China began to appear in the Early Triassic, well developed in the Cretaceous, greatly flourished in the Senonian, and became almost extinct at the end of Cretaceous, with only a few species persisting to the Paleocene, the Eocene and even to the Miocene. This genus favoured such environments as low mountains and hills of arid-semiarid subtropical climates. The genus includes 27 species which can be divided into five groups according to the contact relationship between sacci and body and their relative size. In addition, based on the rugulate tubercles on the body cap and their extent of development, the writers have worked out a species index, with detailed description of 14 new species and some old species.
