BACKGROUND
Previous studies have discussed the special structural adaptations of Late Palaeozoic lycopsids, for example, the dispersal potential of reproductive organs. Based on materials from the Upper Devonian Wutong Formation in Changxing County, Zhejiang Province, China, we now analyze the morphometric and perform some calculation to evaluate the dispersal of sporophyll units of lycopsids.
RESULTS
The fossil sporophyll units are divided into two types in view of obvious difference in shape and we name two new (form) species for them. We also analyze the falling process and give the calculation method of dispersal distance.
CONCLUSIONS
The fossil sporophyll units show relatively poor potential of wind dispersal compared with modern samaras, and show potential adaptation to the turbulent environment.
背景
先前的研究讨论了晚古生代石松类植物的特殊结构适应性，例如生殖器官的扩散潜力。基于来自中国浙江省长兴县上泥盆统五通组的材料，我们现在分析了石松类孢子叶单位的形态计量学并进行了一些计算，以评估其扩散能力。
结果
根据形状上的明显差异，化石孢子叶单位分为两种类型，我们为它们命名了两个新（形态）种。我们还分析了坠落过程并给出了扩散距离的计算方法。
结论
与现代翅果相比，化石孢子叶单位的风散潜力相对较差，表现出对动荡环境的潜在适应性。
