Grammitis poeppigiana (Grammitidaceae) |
|
Grammitis
poeppigiana is a common native alpine and subalpine fern that
grows on rocks. It has the typical thick unlobed leaves of
Grammitis species, but these are only 1-3 cm long. The key
feature that distinguishes it from similar species in the alpine
zone is the type of hairs. G.
poeppigiana has forked hairs, whereas
G. gunnii has
simple hairs on the lower surface, including among the sporangia.
G. billardieri and G.
magellanica have no hairs. |
