RE: Pyrrosia musifolia


Thanks for you information. Our P."musifolia" does match your description,
so I am satisfied that it is P. lanceolata. Another question: what is the
current thinking on P. varia? Jones treats it as a valid species while
Hoshizaki puts it in synonomy with P. lanceolata. Our varia is lighter green
and has narrower fronds than our lanceolata.

Hi all,

If it looks like P. lanceolata, chances are 99.9 % that it is P.
lanceolata, especially if origins are uncertain. There are very few species
looking even a little bit like P. lanceolata, and they are very restricted
in distribution and unlikely to be in culture in Potsdam. Far more likely
that the creeping plant somehow ended up behind the wrong label.
For confirmation: 1. check the sori. They should appear to be formed of
concentric rows of sporangia. 2. Check the scales of the rhizome. Even with
low magnifications, it should be clear that they have a fringed margin.

If that does not solve the matter, get back to me with some sort of picture.
