Hi, I’ve grown this attractive fern from spores and it is quite unusual in that it spreads by distinctive black wiry rhizomes. I would love to know what species it is. Hopefully the 4 pictures attached will help you to identify it for me.
Many thanks
Jonny

I bought this fern from a garden centre in Titchfield, Havant
It does not have fronds bearing sori but it has a green scaly rhizome

It looks so perfect that it looks artificial

It does not have fronds bearing sori but it has a beautiful venation

It is clearly dimorphic

A curious dimorphic fern I bought at a plant store in San Francisco, with no information available from the grower. Scans of both the low and high leaf forms attached, front and back, with one enlargement apparently showing sori. The sample of the tall form is approx. 7″.

Family: Thelypteridaceae ?
Genus: Thelypteris ??
Origin: maybe Uganda
Rhizomatous species, petiole more than 1/3 of the lamina

Can anybody identify this Tectaria?

I purchased this fern recently as I liked its form. It is I believe mislabelled . The label states that it is Dryopteris Cristata Angustata but it seems to be more akin to a Dryopteris Affinis cultivar. What do you think?

Hello Ferners, The fern pictured below I bought as Dryopteris wallichiana, but it certainly does not look like the rest of wallichianas I am growing. In many ways it is very similar .
But it has much fewer scales, a smaller size( same growing conditions and age), deeper venation and is less upright, but only slightly so. Asked a few fern experts here,( Seattle,WA , USA) and they were puzzled. I thought maybe D. yigongensis, though it is very rare in the trade here. Any way I am hoping you will be able to shed some light on this mystery.

Thanks for looking,

Daniel Mount
