An epiphyte is an organism that grows upon or attached to a living plant. The term most commonly refers to higher plants, but epiphytic bacteria, fungi (epiphytic fungi), algae, lichens, mosses, and ferns exist as well. The term epiphytic derives from the Greek epi- (meaning 'upon') and phyton (meaning 'plant'). Epiphytic plants are sometimes called "air plants" because they do not root in soil. However, there are many aquatic species of algae, including seaweeds, that are epiphytes on other aquatic plants (seaweeds or aquatic angiosperms).
Epiphytic organisms usually derive only physical support and not nutrition from their host, though they may sometimes damage the host. Parasitic and semiparasitic plants growing on other plants (mistletoe is well known) are not "true" epiphytes (a designation usually given to fully autotrophic epiphytes), but are still epiphytic in habit.
Epiphytic plants use photosynthesis for energy and (where non-aquatic) obtain moisture from the air or from dampness (rain and cloud moisture) on the surface of their hosts. Roots may develop primarily for attachment, and specialized structures (for example, cups and scales) may be used to collect or hold moisture.

曾经有很多人问过我
dryopteris究竟是什么意思
当初
在网络使用dryopteris这个ID
完全是一种机缘兼巧合
还记得以前本来只使用hotmail的mail box
有时候收到中文的信字都会变成乱码
很挫败
所以决定去奇摩开一个mail box
问题是
不知道是不是太多人使用奇摩的mail box
放哪个ID都跟别人的重复
当时在念F6
然后上biology的时候学了一大堆科学名
就左试一个右试一个
最后dryopteris这个ID成功了
dryopteris是fern的科学名
也是我众多植物中挺中意的一种
因为很简单
就绿绿的没有很花
然后叶片的线条很流畅
我觉得自己其实跟fern很像
epiphytic
寄生在别人身上
让自己成长的路上跌少几次
跟蔡智恒在榭寄生内的形容很接近吧
因为榭寄生也是epiphyte
只是我不懂自己只是依附别人
可以自行呼吸和进行光合作用
还是我根本就是parasite
将别人的营养都抢过来了
这几年一路走来很幸运
即使路途再荆棘再挫折
身边总是有几株植物支撑着我
或许我比较像个黑洞
什么都吸掉
然后什么都没有了
这些人给了我很多
可是我好像也没有因为这些而变成怎样
再过两天就要回大学了
我已经失去了我所有的host
或许我还是一棵fern
失去了host还是可以靠空气残撑着
又或许我也只能变成别人的host
