A closeup of the leaves, which are strongly dimorphic. The sterile pinnae (leaves) are palm or hand-shaped; the fertile pinnae are many forked and much more delicate.A closer view of the sterile pinnae. This is quite a showy fern, with it's long-creeping wiry brown stems and lush, tropical-looking foliage.
In close on the fertile pinnae, which somewhat resemble the sterile leaves, just on a minute scale. The little whitish bumps on the segments of the leaves are the sori, or cases which hold the spores. As with all of our ferns, the tiny spores are windborn and can be transported great distances. I have heard that any sizeable air sample taken nearly anywhere in the world is likely to contain fern spores.
Climbing Fern is an exceptionally beautiful species, and forms luxuriant beds. It would be a natural for those interested in growing native species. I've not seen it in cultivation, but perhaps it is somewhere. The two Asian species are; escaping from cultivation is how they became established in Florida.
