Basically this kind of thing can happen to any consumer electronics, from a TV to a DVD player to an mp3 player or video game unit.

Some ferns species produce mostly sterile fronds (without sori), while also producing one or more fertile fronds (with sori). Other ferns consist entirely of fertile fronds. And in some fern species, the sori only emerge from some of the pinnae, while they are absent from the rest of the pinnae. Examining the stalk of a frond can also be a help in identifying the fern species. The part of the stalk from the ground to the beginning of the frondâs leafy area is known as the stipe.
