蕨类植物

Of them, 8 species belonging to 7 genera and 7 families are Pteridophyte, 10 species belonging to 9 genera and 8 families are Gymnosperm, and 45 species belonging to 36 genera and 23 families are Angiosperm.

通过对福建泉州地区植物资源的考查和研究，发现该地区有珍稀野生药用植物38科52属63种，其中蕨类植物7科7属8种，裸子植物8科9属10种，被子植物23科36属45种。

The evolution of plant undergoes Pteridophyte era、gymnosperm era and Angiosperm era.

植物的演化经历了蕨类植物时代、裸子时代和被子植物时代。

Also, the 121 angiosperm plant species was attributed to 55 families and 93 genus. There was only one gymnosperm plant species.

以大戟科、茜草科、禾本科和竹亚科作为优势科，其中，被子植物55 科93 属121 种，裸子植物1 科1 属1种，蕨类植物8 科9 属10 种。

The Apatosaurus was a plant eater. It ate ferns and tree leaves.

迷惑龙是食草动物，它吃蕨类植物和树叶。

Generally the term is applied to reproductive units produced asexually, such as the spores of bryophytes and ferns.

此术语多用于表述产生无性孢子的繁育单位，例如苔藓和蕨类植物的孢子。

According to the comparative research on Guangnania, the diagnosis of the zosterophytes is expanded. It is suggested that their sporangia have the differentiation in the shape (reniform, rounded/globose to vertically elongate), dehiscence and valves (biconvex or concave/convex).

根据Guangnania的研究和对比，对工蕨类植物的特征进行了扩展，认为孢子囊存在形状（肾形—圆形／球形—纵向伸长）、开裂方式和两瓣的分异。2。

By the support of the present project, 3 articles have been published, 4 articles have been submitted to Grana and Acta Botanica Yunnanica etc and some papers is in preparing.

结果表明：蕨类植物孢子外壁和周壁来源于孢子囊内层绒毡层细胞；孢子表面纹饰有的种类由外壁形成，有的种类是由周壁形成；孢子纹饰是在四分孢子形成后迅速形成的，形成的时间很短并比较稳定。

I know where to find dead grass and bracken ferns, for example, to make a warm mattress in a few minutes.

我知道在哪里可以找到死草和蕨蕨类植物，例如，使一个温暖床垫几分钟。

I picked myself up, ignoring him as I brushed the mud and bracken off theback of my jacket.

我自己挣扎着站起来，不去理会他，只是把外套后面的泥泞和蕨类植物拍掉。

You can use leaves, pine needles, dead grass or dry bracken ferns.

您可以使用树叶，松针，死草或干蕨菜蕨类植物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
