Re: Hymenophyllaceae sp. Wayanad

Probably India because the name Wayanad is the district in this country. But I also found information that it could be Crepidomanes Latemarginale. I don't know what is true.

Hi Vasteq,

finally a Hymenophyllaceae fern that grows and propagates permanently in the tank? Also from Your experience? That would be very cool!!
The Wayanad District is in the Indian state Kerala, belongs to the area of the Western Ghats: http://en.wikipedia.org/wiki/Wayanad_district

Crepidomanes latemarginale is not in this list of Western Ghats Pteridophytes:
http://wgbis.ces.iisc.ernet.in/biodiver ... phytes.pdf
A similarly sounding name is Trichomanes (or Crepidomanes) intramarginale, this species occurs in the Western Ghats indeed:
http://pvmadhu.tripod.com/pterido-pages ... ramar.html
http://fr.wikipedia.org/wiki/Crepidoman ... amarginale
Looks very similar to the aquarium fern, but there are further similar Trichomanes/Crepidomanes species.

The aquarium fern could be IDed with Prof. Madhusoodanan's book "Filmy Ferns of South India": http://pvmadhu.tripod.com/pterido.html or by the Prof himself.

Re: Hymenophyllaceae sp. Wayanad

I know also that it prefer cold water, and weak light. I have 22-23 degre in celcius, and 0,5W/L. I could send a sample to identity.

Re: Hymenophyllaceae sp. Wayanad

I could send a sample to identity.

That would be fine! There might be sori (the sporangium-bearing structures) on older leaves, as in this drawing:

A sample with sori would be most informative.

Re: Hymenophyllaceae sp. Wayanad

I don't think that it have any sori.. but .. maybe I must use bigger macro to see it Reply to my PM.

Re: Hymenophyllaceae sp. Wayanad

Now I see something like you called sori. Grow out of these smaller leaves:

Hallo,

der Farn von Friedrich Bitter und auch der von Vasteq vorgestellte sind möglicherweise der gleiche wie dieser hier auf den Bildern von Claus Christensen (Reise nach Kerala, Süd-Indien, Februar 2012):
https://picasaweb.google.com/109837052880254682778/SouthIndia2012JanuaryAquaticPlantExpedition02?authuser=0&feat=directlink#5733114291077148242

http://www.aquadiscover.com/last_trip.html

Der Farn wird dort Crepiomanes malabaricum cf. genannt (korrekte Reihenfolge wäre Crepidomanes cf. malabaricum). Mit dem "cf." wird ausgedrückt, dass noch nicht sicher ist, ob es sich um die Art C. malabaricum handelt.

Crepidomanes malabaricum wurde 1999 wissenschaftlich beschrieben und soll eng verwandt sein mit den schon länger bekannten Arten C. intramarginale und C. christii:
http://onlinelibrary.wiley.com/doi/10.1111/j.1756-1051.1999.tb01112.x/abstract
Bilder von C. intramarginale zeigen was sehr Ähnliches: http://fr.wikipedia.org/wiki/Crepidomanes_intramarginale Man kann also vielleicht andere Arten nicht ausschließen.
Ich habe das Paper mit der Originalbeschreibung von C. malabaricum nicht und kann darum nicht angeben, wie die Art von anderen ähnlichen Crepidomanes-Arten unterschieden wird.

Hoffentlich wird einmal Genaueres über die Aufsammlungen und vielleicht auch sichere Bestimmung von diesem spannenden Minifarn aus Südindien veröffentlicht.

Gruß
Heiko

Hi there!

I had this plant in one of my last tanks. I got it as Crepidomanes malabaricum. For me the leafs seem to be kind of different shape and a bit wider than the pictures of Hymenophyllaceae. Sure, that these two species could be the same?!

 

[vasteq]

Yes, in my opinion this is the same because leaves can be wider in better conditions.
