Polystitchum x illyricum (Holly Fern/Hard Shield Fern hybrid)

To the best of my knowledge we have not yet discovered the rare 'illyricum' hybrid on Hutton Roof, although there is every possibility we might one day, so I have put some details and photos on the site to describe the rarity in the event.

Ophioglossum vulgatum - Adders Tongue


Population 3 - Hutton Roof
(fertile)

This is the most prolific population, and is found to the North West side of Hutton Roof, and at the side of a well trodden footpath. Their are hundreds if not a thousand or so, covering an area of about a metre wide and over a distance of 18 metre (20 yards) intermittent. The plants are well shielded by emerging bracken. I found the population on 14th May 2020.

Population 2 - Burton Fell
(infertile)

Now we have another fern from yesterday and showing nice emergence photographs, this time the Ophioglossum vulgatum (Adders Tongue Fern).  To my knowledge so far this is only the 2nd population so far found on Hutton Roof Crags. I have checked out this population in both 2019 and 2020 and although you get the shoots and growth of the large leaves you do not get the column, so obviously I have taken it that these plants are infertile.

First I have found on the Hutton Roof complex. So small up to about 4" in height. Population 1 area covers about 11 linear metres x 1 metre wide and holds hundreds of Adders Tongue Fern.

Gymnocarpium robertianum (Limestone Fern or Limestone Polypody)


18th April 2020

Today I was able to find lots of early developing Gymnocarpium robertianum (Limestone Fern)



 Gymnocarpium robertianum (Limestone Fern or Limestone Polypody)
This photo shows two early stages of development
On the lower left it shows closed croziers, and on the larger one on the right
shows it further on with early opening of the croziers and taking on its true lime green colours.

Blechnum spicant (Hard Fern)

Showing Crozier just starting to unravel

We don't get a lot of this particular fern on the Hutton Roof side because it favours acid soils (not limestone), but here and there (up to 4 previous records I have so far) we do get small pockets were you get a build up of soils, thus supporting the species.

If you go on the opposite side of Dalton to the Keer Valley, this species is very common on the large sloping banks to the small River Keer.

I like this photo in particular because it shows the varying stages of the croziers and their unravelling process

I have so far identified three small areas were this species is recorded on the whole of Hutton Roof, although I am sure there will be more undiscovered small pockets. 1) is near the first escarpment after leaving Plain Quarry, Another is at the entrance to a badger set.  The species grows on acid soil and is plentiful if you go over the other side of Dalton in the "Keer Valley".

Phegopteris connectilis (Beech Fern)


There are 5 separate populations recorded on the Hutton Roof complex and all populations are lying from a Central to the East side of the complex starting from a area a few hundred yards just east after leaving the Uberash Breast (Cairns areas), and continuing East the largest populations cover a large split area over a 200ft length incline. Another 3 populations are lying high above the Kelker Well areas.  All populations lie next to well established footpaths.
