Re: Anyone had any experience with this wierd plant?

Yup, aquatic magic is notorious for taking pics of non aquatic plants submerged. Little to the buyer's knowledge the plants are usually only submerged for a couple of minutes while they take the picture. Add a shrimp and wahlah it looks like it has been flourishing underwater for years!

Re: Anyone had any experience with this wierd plant?

I corresponded w/ them on this:
Dear aquaticmagic,

Why do you sell this as an aquatic plant? It will die if kept under water!


They replied:
Hi!

It can live underwater no problem =)

Cheers!

Re: Anyone had any experience with this wierd plant?

Well thats interesting... two of our brainiacs on opposite sides of the fence, one says its non aquatic and the other says it is newly discovered by the Japanese company Rayon vert...

Cavan.. Aaron... who's right? :boxing:
Naturally I agree with Cavan. You have me confused with another Aaron. :D

Re: Anyone had any experience with this wierd plant?

As far as my searching tells me...Plagiomnium Trichomanes is a bryopphyte with some (alleged) medicinal properties. It is harvested (in China or distributed from there) and it (or its extracts) are offered for sale world wide. I can find no specifics on exactly where it grows or its natural habitat. It has been quite frustrating, really. I plug in a word like Holotype and google says "Huh?".

The few reliable looking references generally wast to talk about the biochemistry and/or genetics of the plant and any background information is beyond reach as I'm not willing to subscribe ($$$), so all I can see are the abstracts.

I don't have the feeling that this particular species grows in North America though...

Try Google Scholar - That understands words like Holotype, and finds scientific papers.

Re: Anyone had any experience with this wierd plant?

I tried it - many of the same listings as before, but a new one or two including one thet lead me to the email address of a moss expert at the local botanical garden. I sent him a note asking about it.

Re: Anyone had any experience with this wierd plant?

Quick & interesting reply...

Hi,
Mosses are generally defined as terrestrial plants although some are said to be aquatic. For those growing in aquatic conditions, they are not really true aquatic in nature because at times they do expose to air during dry season. No mosses are growing in ocean or in lakes, ponds, etc. Most of the aquatic mosses are found in streams or sometimes fens where they are immersed most of the time. However, I have found my friends who grow a few mosses in aquaria with air pumps and under a good light condition. I asked them how long the mosses have been in water and they said a couple of years had past. So, I guess it is possible to grow mosses in an aquarium, but I doubt they can survive for an extensive time, to say five or ten years. Anyway, it all depends on the condition of an aquarium.
It is hard to identify the moss you showed to me. It looks like a Plagiomnium species. For the name Plagiomnium trichomanes, it has been synonymized with P. acutum. So, its distribution is much wider now than it was previously reported from China and Japan as P. trichomanes.
Hope this is of some help to your inquiry.
So, it's a definite "maybe" in my book - and P. acutum



(which seems to look a lot like P. cuspidatum^).

I guess you just have to try it... I can also see a ton of room for errors in properly identifying these as you probably need a microscope, spores a good key and expertise to do it with any certainty.

This is why you should have kept your original handle, Aaron! (one of the coolest, I must add!)

here is what I know... I first got the plant in question (or something that looked quite like it) in 2003 in Hong Kong. they sold it in "sheets", obviously stripped off rocks from somewhere locally. It actually looked more like P. acutum at the time. I set it up in a number of environments (both submersed and emersed) and it sat there, doing nothing for a long time.

I think a year later, through correspndence with one of the old time members of the board, I was given a piece of what was called P trichomanes. From what I understand, it originally came from the person who first posted that wonderful picture on Tonina Forest that we all are drooling over. Unfortunately, when I finally received it, it ended up looking nearly identical to the plant I bought in Hong Kong (which was still alive, showing little to no growth)

At that point, I had pretty much given up on the plant and placed pieces on some sphagnum moss and plopped it in my Cryptocoryne case. Just for good measure, I took a few fronds and tied it to a branch in my planted tank.

apparently, the prior techniques of keeping this plant in plastic containers with varying degrees of humidity was NOT ideal. in both situations, the plant took off. in the case (emersed) it turned into a lovely green puff ball, very much looking like the picture that was posted. underwater, it was more of a creeper which took on the look of a miniature underwater Ficus repens. Not the puff ball seen in the picture, but very beautiful and distinctive none the less. The "leaves" became very round.

So... is this indeed P. trichomanes? i don't know, I'm not a bryologist.
Does it grow under water? yes, but it looks different...

...and no, I don't have it anymore. still bitter over that loss... To make it worse, the pictures of it are trapped on my old frozen laptop.

Hope this helps...

Re: Anyone had any experience with this wierd plant?

Aaron - Thanks for posting your input!

More from Aquaticmagic (I asked what, if any, special requirements the plant had)-
Hi!
It prefer medium to highlight. Water temperature not critical and less demanding than moss. Water parameter is not defined yet for this plant.
This plant is something very new to hobbist =)
Cheers!
Mike
So, I'm thinking my new moss expert friend is probably right when he implies that YMMV with all of these "occasionally semi-aquatic" species and that P. trichomanes, a.k.a. P. acutum, has distinct immersed & emersed growth forms (like Marselia species etc.). I'd also feel pretty comfortable guessing that both pictures just above are of the immersed form(s). I think I may have to get some of this stuff at some point down the road (but getting some ground cover is a higher priority for me now).
