In my opinion this is one of the most beautiful small bolbitis I've ever seen. Name suggests that this fern comes from the Gua Angin (Wind Cave) near Sarawak river in Indonesia. But i think that Vladim should better describe history of this fern. Temp of grow similar to Cuspidata, but i have it for a short time to tell more. Has a beautiful detailed edges and sharp top of the leaves.
Growing fine in my tank with parameters:
KH 6
GH 14
PH 6,8

Hi vasteq,
looks indeed similar to Bolbitis heteroclita "cuspidata" and might be a variant of B. heteroclita. Emersed specimens with spores could be ID'ed.
With B. heteroclita forms such as "cuspidata" I have the problem that mature submerged leaves become dark-brown / blackish. Maybe due to suboptimal conditions.

Quite similar but Gua angin has a sharp leaves. Size is also similar.:



Photo wit both Bolbitis (not good quality. In foreground is Cuspidata. Gua angin is on the net). On the left is Bolbitis Heteroclita Difformis - smallest Bolbitis:

Hi vasteq,
thank You for the pics! It's possible that there are much more variants from this Bolbitis group.
I wonder if there are ones remaining a good-looking color of mature leaves, not turning dark when submerged.

what do you mean : not turning dark when submerged.
I observed this what do you wrote, but it not only applies to mature leaves, also sometimes the young leaves if they change the environment. Leaves could stop growing and turn brown. That's the same also Bolbitis Cuspidata and Difformis. However some mature leaves are green to this day. I think that depend on water quality or maybe like i said: change environment. The "passing in bronze" leaves are release the small spores (i observed it on Difformis, Cuspidata, Pteridophyta "X kiat". But on Gua angin not yet) Pteridophyta "X kiat you can se here (you can see a smal spore on non-trident leaf):

Hi Vasteq,

yes, I meant the same what You've observed. Till now I saw it on all forms of B. heteroclita I tried submerged (that means, also "cuspidata" and "difformis"). It might be difficult to keep conditions where these brown areas on the leaves don't appear (low light?).

I believe also Your Pteridophyta "X kiat" is a form of Bolbitis heteroclita (for ID it must be a full-grown emersed plant, best with spore bearing leaves = sporophylls).

I mean the little round thing on the non-lobed leaf of Your "X kiat" isn't a spore or a sorus, but a bulbil from which a daughter plantlet may develop (vegetatively).
In ferns the sori develop on the underside of the leaves only. In Bolbitis species, the spore-bearing leaves differ much from the sterile leaves, they have longer stalks and narrower leaf blades. They don't have single sori but the whole underside of the leaf blade is covered with brown sporangia (spore capsules).
Here a drawing of the 2 leaf types: http://140.112.8.149/tai2/node/354

So Crepidomanes Auriculatum should be also from a family of Bolbitis, because it has also a "little round things" on the outer side of leaves?

The fern imported from Taiwan as "Crepidomanes auriculatum" is IDed by the pteridologist Prof. Brigitte Zimmer (Berlin) as Asplenium cf. normale: neue-und-besondere-wasserpflanzen/asplenium-cf-normale-crepidomanes-auriculatum-t17447.html#p151776
Buds or bulbils or gemmae on the leaves for vegetative propagation, similar to them of Bolbitis, occur in several different, not closely related fern groups. E.g. in many Asplenium species. In Tectaria gemmifera they get as big as a pea and drop off.

Do you know that Asplenium ruta-muraria and Asplenium trichomanes could grow underwater? I found it at holiday in Croatia, (Plitvice lake) but dont want to grow underwater, or maybe i just wrong adaptated it.

I can't say it for sure as long as I haven't tried it, but I mean, most probably not! These 2 Aspleniums are quite frequent on old walls also here in Germany [edit: and I believe You can find them easily in Your country too], naturally dwelling in rock crevices, and drought-adapted ones, never occurring in wet habitats. Asplenium is a huge genus with species from very different habitats.

Hi there!

Very nice Bolbitis! Why haven't I seen this threat before?!? :eek:

@Alan
Does the photo shows a submerged growth form of this plant? It's beautiful!
