中文摘要：

利用扫描电镜对中国产岩蕨科（Woodsiaceae）3属18种植物孢子进行了观察。结果表明，孢子单裂缝，两侧对称，极面观为椭圆形或宽椭圆形，赤道面观为半圆形或超半圆形；极轴长32～50μm，赤道轴长43～61μm；外壁表面光滑，由周壁形成孢子表面纹饰的轮廓，根据表面纹饰，孢子可分为5种类型：（1）片状纹饰：周壁表面形成疏密不一的片状褶皱，并连成网状；（2）脊状纹饰：周壁表面形成脊状褶皱，并连成网状；（3）翅脊状纹饰：周壁表面具脊状褶皱，并连成网状，脊的顶端具流苏状不明显的低翅；（4）翅状纹饰：周壁外层形成翅状纹饰，翅的边缘较薄；（5）丝毛状纹饰：周壁结构疏松，由细丝交织成立体网状。上述孢粉学特征表明，岩蕨科是一个自然的类群，其3属的亲缘关系较近，都是岩蕨科的合理成员。

英文摘要：

The morphology of spores of 18 species（belonging to 3 genera）of Woodsiaceae from China was examined by the means of scanning electron microscope （SEM）. The results showed that the spores are bi- laterally symmetrical and monolete. The spores are often elliptic or wide elliptic in view of polar face and hemispheric or super hemispheric in view of equatorial face. The length of polar axis is about 32-50 μm. The length of equatorial axis is about 43~61μm. The exospore of spores is smooth and the ornamentations of spores are formed by perispore. They can be divided into 5 types according to the ornamentations. （1） Lamellate.bearing the sheet folds which formed reticulate ornamentations; （2） Lophate. bearing lophate folds which formed reticulate ornamentations; （3） Alar-lophate：bearing lophate folds which formed reticu- late ornamentations,but there were some short swings with unobvious fringe edge in the top of fold; （4） Pterate.the pterate folds were swing-like and its edge was thinner relatively; （5） Sericate. the structure of perispore was composed of filaments which interwove loosely with each other. From the characteristics of palynology, the species of Woodsiaceae belong to a natural group and the relationship of the 3 genera of this family was closely,and they are all the reasonable members of Woodsiaceae.
