good to hear that i could feed the microsorium hunger in you all!!!

MICROSORIUMS ARE WICKED COOL!!!

The owner of this store actually collected this plant, unfortunately i forgot where

so its not a cultivated variety, gotta b a microsorium species and on top of that, chuck told me some extra evidence, that the keikis that come off of it, also form those long fingers comin off of it...they dont turn into normal pteropus leaves..so mos def different from tropica, but what else would u call it??? "KICK @$$" Microsorium sp.

when i took some pictures last summer i went up, the large plant was the size of the one in the bottom left, of the picture taken some distance back, that smaller specimen is also narrow leaf tropica, and to the right of that one, (bottom right) is emersed reverse tropica

i was thinkin that too, cuz the one in your pic has fingers that come off right next to one another, sharing the same base of the main stem, but this one the fingers come out almost at even intervals

KEN-actually he wasn't selling it at all, and if he had to sell it he told me he would sell it 10,000 yen for an inch of rhizome!!! thats about $100 ;-P well worth it

and would you believe it, the last week i was in japan he told me he had just received a new microsorium, unfortunately i didnt get to see it

but i will soon enough

on top of that, he got news of 2 more varieties, he's currently hunting them down now...but they're called
-narrow leaf red-im assuming its narrow leaf with red tips like the normal red cultivar
-microsorium "duet"-not expecting too much of this one, he and everyone else i talked to about it is assuming its just a mix of 2 microsoriums, but you never know how nice it might be ;-P

Hi,
In my study I dealt with the taxonomy of Microsorum and Microsoroid ferns respectively. This is a huge genus, indeed - and a complicated genus, too. It is in need of revision. Cladistic analyses (Dr. H. Schneider and H.-P. Kreier) have evidenced that M. is not monophyletic (not sharing one common ancestor). E.g. M. pteropus is closer related to species of Colysis (or Leptochilus) than to other Microsorum species. Several other genera "nest" in Microsorum, e.g. Lepisorus or Lecanopteris.
According to the last revisions (Bosman, Nooteboom) the only aquatic Microsorum species is M. pteropus. (Apparently M. insigne, too, can grow on boulders in streams and in waterfalls.) All other Microsorum species are epiphytic or terrestrial. Some Colysis (Leptochilus) species are rheophytes and occur on streams (possibly suitable for aquariums??).
ID of Microsorums can be difficult. Important characters are e.g. venation pattern, form, arrangement and innervation of sori, form of the cross section of rhizoms, rhizome scales, or outline and texture of leaves.
The fern in Inspire91's photo is exceptional, but it needs details in order to identify it, e.g. venation pattern or density of scales on the midrib of the leaves.

wow i never actually read about the background behind the species of microsoriums, really interesting stuff

thanks

Hi Inspire91,
in few words, M. pteropus is maybe the most popular Microsorum species due to its worldwide distribution as an aquarium plant, but it is by far not a typic Microsorum, and perhaps it is rather among Colysis (Leptochilus).

Could You make a close-up photo from the undersurface of the leaf of Your crazy fern where the midrib (with scales?) and the venation are visible? I'm curious if they are characteristic of M. pteropus!

Inspire91 · 10-23-2006, 11:03 PM

I wish i could but I dont actually have this plant

...all the pictures that i took were in a shop in japan..so sorry about that...i guess we'll never know about that :-/

miremonster · 10-24-2006, 10:21 AM

Oh, sorry, now I see I didn't read Your former postings exactly!

I think it looks similar to a new fern species I just got coming out of Aquafleur nursery in the Netherlands. Check out this picture (picture is not mine):

Hahah just realized this post was 2 yeas old, the good old search button goes a long way lol
