Costa Rica Fern 2

Elaphoglossum-eximium-2-1.jpg Elaphoglossum-eximium-1-0.jpg

My dementia meant that I was gettig in a bit o a mddle so I do not know if either of my first mailing attempts got through.

My wife and I recently had the privilege of visiting Sri Lanka a country which we have wanted to get to for many years and indeed this trip was originally booked for 2020. In the meantime I have been diagnosed with early stage Vascular Dementia / Vascular Parkinsonism. When I was 21 I set myself a target to photograph 25,000 species of identified living organisms in my lifetime. I am up to 23,600 but I am now 73 and hope that I can still achieve my objective. (The total includes 461 species of Pteridophytes).
I only managed to photograph three fern species in Costa Rica. (Most of the ferns that I saw were not fertile or only had very immature sori)

I would be very grateful if anyone might possibly be able to suggest a species identification of these three species. (I have been a member of BPS for many years).

Many thanks

Costa Rica Ferns

My wife and I recently had the privilege of visiting Sri Lanka a country which we have wanted to get to for many years and indeed this trip was originally booked for 2020. In the meantime I have been diagnosed with early stage Vascular Dementia / Vascular Parkinsonism. In addition I have severe psoriatic arthritis which is increasingly limiting my mobility. When I was 21 I set myself a target to photograph 25,000 species of identified living organisms in my lifetime. I am up to 23,600 but I am now 73 and hope that I can still achieve my objective. (The total includes 461 species of Pteridophytes).
I only managed to photograph three fern species in Costa Rica. (Most of the ferns that I saw were not fertile or only had very immature sori. This was the case with the Adiantum but nonetheless I hope it may be recognisable)

I would be very grateful if anyone might possibly be able to suggest a species identification of these three species. (I have been a member of BPS for many years).

I recently found this fern on the Nature Reserve I work on in Lincolnshire. I have identified it as Hard Shield Fern (Polystichum aculeatum) which appears to be localised within the county and indeed would be a first for the Reserve. However, being fairly new to pteridophytes I stand to be corrected and would appreciate a second opinion.
Many thanks.

Is this fern a Nephrolepis?

I found this fern in a local garden centre amongst their “Hardy Ferns”. It was labelled “Varens”, which is I believe Dutch for Fern. The label stated that it is suitable for indoor or outdoor use. I think it may well be Nephrolepis Exaltata ‘Green Lady’ which isn’t suitable for outdoors. What do you think?

Irish Fern ID Please

Please can you help me identify this fern.
Given as a present from County Cavan in Ireland.
It is growing now in chalky soil in Hampshire. Still green in January.
The fronds are scally, up to 60cm long and quite hardy, though the pinnae are quite fine & delicate. No sign of any sori on the back.
thanks – Philip

fern died in my care before I could identify it

Hello. I sometimes grow fern from spores as a hobby. A friend once sent me spores from the US East Coast, out of which grew Christmas Fern, but in one of those pots also grew another fern I couldn’t identify. When a friend tried to separate them, the unidentified fern died, so I only have a couple photos. I’d really like to know what fern that was, so if, despite the lacking source material, somebody could give me any hints here, I’d be very glad. I got more photos of the likes as those that I uploaded but also in higher resolution. I assume that this fern either came with the Christmas Fern spores, or it’s here locally from central Europe and found its way into the pot by chance.
Thank you for your time.
