Cerastium fontanum subsp. holosteoides (Common Mouse-ear) was a nice surprise today on the dunes at Grogan Burrow, as it is a new subsp. for the county. I have known this almost hairless Mouse-ear on the dunes of Ballyteige Burrow since about 2011, but have never seen it flowering. Today as soon as I saw the flowers, noticing how much larger they were, it took me back to seeing this subsp. in the Comeragh Mountains in Co. Waterford.

The leaves look glossy as they are hairless, except for along the margins. The internodes are hairless except for a single row of hairs.

I now have to visit Ballyteige Burrow to see if the hairless Cerastium fontanum there are the same subsp.

Matthiola sinuata (Sea Stock) refound in Wexford, thought to be extinct in Ireland

 Sea Stock refound on the Wexford coast. A species that was thought extinct in Ireland. The Ireland Red List No. 10 Vascular Plants says it was last seen in Ireland from Co. Clare in 1933, and for Wexford says 1925. In my database for the county I have records up to the 1970s, which would seen to be correct, as more than one person has mentioned seeing Sea Stock in the county, since I reported the Wexford site found on 2nd April. I counted 85 plants, but might be as many as 100 plants. The Sea Stock has been there more than one year, as there were tiny little plants as well as large rosettes. I walked this stretch of coast in 2016 looking for Atriplex, surprised I didn't seen it then if it was there, would seem more likely that a winter storm unearthed buried seeds.

Cotoneaster frigidus (Tree Cotoneaster) growing on the site of a ruin, new species for Wexford

 I was out trying to refind Carex strigosa (Thin-spiked Wood-sedge) in the only hectad in the county where there is no post 2000 record. No luck as where the Carex once grew had been drained and planted with trees. While in the area I noticed two large chimneys poking above the trees, my first thought was there might be snowdrops in the wood, if it was a ruin (see below). It was a large house at one time known as Coolbawn. There was a Cotoneaster self-sown on the ruins, plus a very large tree of the Cotoneaster (see above), which I took to have been planted. As the tree still had leaves and berries I was able to ID it as Cotoneaster frigidus (Tree Cotoneaster) a new species for the county.

 Also self-sown on the ruin was a number of bushes of Veronica salicifolia (Koromiko) (see blow, light green bush in picture), this is a new hectad record for this Veronica. Had no luck in finding any snowdrops, but very much enjoyed looking around the ruins.

Map showing average number of species per monad in each hectad within Co. Wexford

Map showing average number of species per monad within each hectad to the of 2018

By the end of 2018 all but one monad had species recorded in Co. Wexford.

There are 2558 monads in the county.

The aim when I started recording for the Flora of Co. Wexford in 2008, was to record one monad from each Tetrad across the county. Paula O’Meara started recording in 2010. A couple years later I decided to aim to visit every monad, something I didn’t really think possible by the end of 2019. Not sure when it was decided to aim for a minimum of 100 species per monad.

S8251 is the only monad with no records.

There are 404,870 individual monad species records across the county.

The average number of species for a monad across the county is 158.

153 monads have under 100 species recorded. The majority are part monads around the county margin, where the neighbouring county has the largest area of land, or most of the monad is in the sea. There is one monad that has only Zostera marina (Eelgrass), even at low tide there is no land above sea-level. Another monad has only a sandy beach as land, the one species being found is Atriplex laciniata (Frosted Orache).

Two whole monads only have 1 species recorded, hopefully they will be visited in the next couple of weeks. Access can be a big problem, this is usually the reason why some whole monads have less than 100 species recorded. Other whole monads just don’t have a very good variety of habitats. For example one monad was all arable, and weed killer had been used along every field bank, only the toughest of species surviving.

Looking forward to seeing how 2019 turns out, and how many more monads can top 100 species.
