The results of character evolution history reconstruction shows the SC in PT and AD clade might be a homoplasy character; also, the SC in PT clade might have multiple origins. SC in Pteridaceae has some special characteristics:(1) the cell long axes usually run parallel to the lateral veins;(2) Most of Pteris and Adianum species have VSC only in lower epidermis;(3) Species have ISC also have VSC.(4) Presence of spicular cells is highly correlated with the long veinal epidermal cells. Species have type III silica deposition type usually have longer and narrower veinal epidermal cell compared with ordinary epidermal cells; Species have type IV silica deposition type also have long epidermal cells, but not significantly different from ordinary epidermal cells.

本实验中亦发现凤尾蕨科之矽异形细胞具有几项特色：(1)矽异形细胞之长轴多与叶片侧脉方向平行(2)发现多数铁线蕨属以及凤尾蕨属植物仅下表皮具有脉上矽异形细胞；(3)具有脉间矽异形细胞的种类会同时具有脉上矽异形细胞；(4)长条形的侧脉上表皮细胞与矽异形细胞具有相关性，仅具脉上矽异形细胞的分类群之脉上表皮细胞均较一般表皮细胞细长；具有脉间矽异形细胞之物种之脉上表皮细胞亦为长条形但形态与一般表皮细胞常无明显形态差异。
