中文摘要：

Pecopteris lativenosa Halle是栉羊齿属中羽叶形态变化十分显著的一个种。作者在详细观察的基础上。尝试性地运用定量统计和方差分析方法判定该植物具有代表性的各项特征，提出了普遍存在的5种小羽片类型、6种末次羽片类型和2种末二次羽片类型，以及各类型小羽片、末次羽片、末二次羽片和末三次羽片的空间分布关系。并以此为依据绘制了Pecopteris lativenosa Halle三次羽状复叶复原图。这一复原图能够解释以往发现的Pecopteris lativenosa Halle标本所属类型。

英文摘要：

Pecopteris lativenosa Halle is one of the pecopterid species with marked intraspecific variation of leaf morphology. Based on observation of nu merous specimens collected from the Early Permian Taiyuan Formation in Wuda, Inner Mongolia, and with an application of statistic analysis, the major features of Pecopteris lativenosa Halle are tested and verified. Five types of pinnules, six types of ultimate pinnae and two types of penultimate pinnae are differentiated, and their spatial locations on a tripinnate leaf are evaluated. As a result, a reconstruction of a tripinnate leaf is realized. It is applicable to interpret previously described specimens of this species. Qualitative and quantitative methodology in morphological reconstruction of fossil plant is briefly reviewed.
