Any Fern specialist?

[emiliasgarden]

Among the meny collections that i have, i have one of Ferns, mostly tropical ones. Now, from those i have, several of them just appeared and were not collected or bought by me. So if there is any Fern-lover that can help me ID them it would be great.

****************************************************
This one i suspect that is what is called in Spanish as Venezuelan Fern (Helecho venezolano). But i cannot find any info about it. Any idea of its scientific name?

The larger plant i have:


Close ups of the rhizomes:



And a smaller one:


These ferns are very agresives. Thye appear in any place in my house, from Bonsai pots, to deade leaves in the ground of the greenhouse, to covered seed trays.

****************************************************
This other is a fern that just appeared a couple of years ago in a American Elm Forest Bonsai that i have. I do not know if a spore just fall in that pot, of if it came with the Elms from New England. It appeared a few weeks after i potted the trees.

The plant right now:


A closer look of the base:


The spores:


****************************************************
This is one that is native to PR. They grow attached to the trees in very humid forests. This one is fro ma cutting i took from the Lands ofmy Family in the Northern Mountains. It is a small plant. It always stays like that, thought the rhizomes can cover entire trees.

The plant:


Detail of the rhizomes:


The spores:


****************************************************
This is another native of PR. It grows in the soil under large trees. Every place i have seen this one the soil is covered by dead and wet leaves. The plant i have is a small one, it is only like 8 or 10 inches of leafspan. But mature plants can be a couple of feet of leafspan.



****************************************************
This is another PR native. It grows in the mountains, in sunnier sites. It is very common to see them living inhe roadsides. This one and the other onesi have from this "species" have not been collected, they just germinated in some pots.

Detail of the leaf:


Detail of the base:


****************************************************
Now this "species" is the most curious of all... These ferns germinate in every place is use Sphagnum Moss. I do not know if it is that they love the constant humidity of Sphagnum, or if they come in the Sphagnum. I do notthink these can be natives of the Islands. I have never seen them in the wild.

2 plants growing in Nepenthes' pots:

Any help with them? ;D

some unknown fern too

Hi Merlin
That's a very interesting fern.I recently found a very similar fern growing in a couple of pots that i have and have potted them up individually.
There seems to be some similarity with the plant u show but i also note the obvious difference of toothed lamina margins on the one i have and the presence of black hairs on the rhizome of the one you have.
They do not take well to drying out and seem to require a constantly moist media,i keep them in a bright place with no direct sunlight and they appear to like that.This to me would indicate that the fern would not grow in Hong Kong apart from in protected waterfall/stream fed gullies that stay moist even during the dry winter months.How they/the spores got into my rooftop greenhouse dome is a mystery.
I can only assume that these are a juvenile stage plant and may well mature into a very different looking plant.







I am reasonably familiar with alot of ferns in Hong Kong ,we have over 200 fern species here, and i have not seen this one here in the wild.This plant has really got me baffled.I am most interested to find out what it is.


Peace

nice fern, im not great with fern names, but maybe mine is a diplazium?

Good morning, I'm no specialist but I did stay at a holiday inn last night and then came home and grew this staghorn.

[twoton]

Holy Brother of God! I knew that some platycerium species grow leaves up to six feet long, but I didn't realize p. bifurcatum (I think that's what this is) would get this large. A while ago, a neighbor presented me with a large specimen with 5 or 6 "grow plates" or whatever the brown shields are called, and in my eyes that's a monster already. But this thing must be six times the size of mine!

Incidentally, how did staying at a Holiday Inn inspire you to grow this staghorn?

[bogbaron]

Hey Twoton, They may not have any Holiday Inn ads where you watch tv. My reference to H.I. is an attempt at humor. In their ads here on tv they try to suggest someone who stays at H.I. is smarter than most. For example a fellow is preforming sugery and the nurse say you're wonderful doctor and he says oh I'm not a doctor but I did stay at a Holiday Inn last night. Actually that isn't my staghorn fern. It's my friend's and it is so heavy I always help her put it inside when freeze warnings come out. She has a lot of nice plants but no cps.

Thanks for solving that cross-cultural conundrum. I actually don't have any TV service (neither cable nor wireless, I just watch DVDs), plus I live in Taiwan, where there's no Holiday Inns at all.

It's my friend's and it is so heavy I always help her put it inside when freeze warnings come out.

Put it inside where? Not in a terrarium, I presume? :-)

[bogbaron]

Good morning Twoton, We take it inside to her old kitchen which is now a large pantry. I have a few pictures of some baby staghorn ferns and one of an unidentified fern. I'll post them if I can find them. In the mean time here is a picture of where one of the small staghorns hangs. A leaf might be recognizable, if you look close, right behind the dragonfly's posterior. Have a good day, BoGHead

Jorge Joel:

I get these volunteering all the time in my hanging moss baskets. I think the spores ship with green moss used for hanging baskets, at least in my neck of the woods. I enjoy them, and just let them grow without worries. If you give them a lot of moisture without drying out, they can become attractive.

bogbaron, loved all your photos so far...very nice!

[bogbaron]

Hey Ludwig, Here's some Boston fern, I think, which sprouted up in this clump of bromeliad. Have a good day, BoGHead

[bogbaron]

Here's a few pics of a couple of monster staghorns and some new growth plates on a staghorn.

Greetings. The Platycerum bifurcatum you have pictured is the one we call the Elkhorn. Platycerum superbum is what we call the Staghorn
