Fern i.d.
Falmouth Spring Show yesterday so I had a quick look around Gyllyngdune Gardens. Saw this fern growing on a tree fern, and I also grow it (also from a Dicksonia trunk). Can anybody put a name on it for me? Years ago I convinced myself it was a Microsorum but now I am older and more forgetful, so I am no longer convinced (looking down quickly to check I haven't dribbled down my shirt front).

Re: Fern i.d.
I have something similar ( maybe the same ) growing on my DA's that was kindly identified by a member on this forum as Phymatosorus (microsorum) diversifolius ...............

Re: Fern i.d.
Phymatosorus looks likely, but P.pustulatus is more likely if the trunks came from a southern origin.
Habitat shots of it on Dicksonia in Tasmania are on this board .

ps. I'm writing rubbish this morning. My suggestion is synonymous with P.diversifolius in some sources!

Re: Fern i.d.
John and Taffy, you're seeing the juvenile simple fronds of the Australian fern, Phymatosorus diversifolius. The mature fronds are pinnatifid and look like this :
Here are both juvenile and mature fronds:

Re: Fern i.d.
Thanks for the help Valdy, I grow this one as well
but I was beginning to doubt the little one - I got it in 2006 and it is still producing juvenile leaves so I had started to question it.

Re: Fern i.d.
John, your most recent pic looks like Microsorum grossum (used to be called M. scolopendria, but that is a different species from Malaysia and not generally in cultivation). I don't think it's Phymatosorus diversifolius (you can't go by nursery/commercial names; they're usually hopelessly wrong!)

Re: Fern i.d.
Ooh - thank you again Valdy!
I got this one as Phymatosorus scolopendria but it is fairly hardy here, so I had asumed it was in fact P. diversifolius.
I got this as P. scolopendria 'Greenwave' and it wasn't even slightly hardy, so I guess this is a form of the Malaysian M. scolpendria? It was available as a house plant for a short time, I don't know if it's still on the market.

Re: Fern i.d.
Hi John
Of your last two pics, the first one is definitely Phymatosorus diversifolius again, with very nice mature fronds.
The second pic is a variety of Microsorum grossum. Both M. grossum amd M scolopendria are tender ferns coming from tropical Asia, but it's M. grossum that is widely cultivated in places like Florida and Hawaii and often used as tropical ground cover because the fern wanders about on the ground with those long rhizomes. The horticultural trade has produced several ornamental varieties of this species, including the twisted form you have.
As I said previously, M. grossum is still often called M. scolopendria (or M. scolopendrium) in the trade, but this is now known to be wrong. M. scolopendria is not known to be in cultivation and is a more difficult plant to grow.
Hope this helps!

Re: Fern i.d.
I might have that. I haven't chimed in because I'm not 100% sure and two its been a very slow grower and seems to need more warm shade than I have. It used to be on the porch..and it did well. I put it in the back yard in its pot on the ground surrounded by driftwood and sphagnum moss hoping it would creep over that. Its slow growth combined with winter and cats that seem like to walk in that spot have got me to think of..back to the porch. So all I can say..its more warm needy then most ferns I have.
