Pyrrosia includes some very useful ferns. Some are fairly cold hardy, and others make very decorative baskets.
Pyrrosia lanceolata now includes many plants which were formerly species in their own right. It seems likely some will be separated in the future. Both examples above are now considered forms of lanceolata. The one on the left was called P. varia. The one on the right is a much smaller plant. Both do well in a tree fern basket.
Pyrrosia lingua is a tough little ferns. The plant above is Cv. Monstrifera. Normal forms have simple, entire, pointed fronds, which are fairly stiff. This species has a degree of cold hardiness, usually stated as hardy to zone 7.
Pyrrosia longifolia makes strap fronds up to a yard long. The plants in the picture above are grown from spores of a crested form. These are some of the most beautiful ferns when well grown.
Pyrrosia nummularifolia is a delightful little ferns. The button-like leaves tend to clasp the substrate, and I have been told it can cascade for some length. The photo on the left shows a fertile leaf., along with the fuzzy grey underside.
Pyrrosia piloselloides has extremely fleshy leaves, sometimes nearly globose. Fertile fronds are longer and more linear.
