Both species are similar in having 1-pinnate-imparipinnate laminae, entire and linear pinnae, and free venation with simple or furcate veins. In Pteris longifolia, however, the pinnae are articulated to the rachis, whereas in P. vittata they are not (i.e., each pinna has a short petiolule that is continuous to the rachis). The pinnae base shape can be helpful too: cordate in P. longifolia vs. truncate in P. vittata.
This is a speices of Pteris. There are a couple that commonly occur on rock wall, e.g. P. longifolia and P. vittata.
Great. Thanks. P. vittata is native here.
