槭葉石韋(學名:Pyrrosia polydactyla)為水龍骨科石韋屬下的一個種。為台灣特有種,分布於全島海拔400~2800公尺的山區,常著生在大樹枝幹或是岩壁,所以有崖生石葦別名。近年來因大量破壞,數量已較為稀少。槭葉石葦種小名polydactylis為「多指的」的意思,形容這種植物葉片明顯裂成多指狀,也因此有人以Manyfinger Pyrrosia作為它的英文名稱,或稱為Five-fingered Taiwanese Tongue Fern,Five-fingered Tongue Fern,都是以此特徵來稱呼。臺灣野外有類似的松田氏石葦(Pyrrosia matsudai (Hayata) Tagawa),但它大多是單葉,偶而出現的掌狀裂葉多為三出且不對稱,與槭葉石葦不難區分。

Pyrrosia polydactyla is a short slow creeping upright fern. New light green fronds turn darker over the season. The new fronds are covered in hairy silver stars. The midrib is darker than the similar P. hastata. The fronds are felt like to the touch and have three to five lobes that can extend to 14” long by 10” wide. The sori without indusia will open in late winter to early spring spreading bright yellow spores. These ferns are easily propagated from division or spores. The spores should be sown when ripe and are slow to germinate. Pyrrosia polydactyla is a drought tolerant evergreen fern that is easy to grow in a container with good drainage. Move containers to a dryer and or warmer area during a prolonged wet season or cold snap. Felt ferns like good drainage in the garden. It prefers loose soil with a decent slope as well as protection from the freezing weather. P. polydactyla makes a good house plant that needs little water or nutrient requirements.
