Ulex x breoganii a new hybrid gorse for Wexford

Ulex x breoganii is a hybrid between Ulex europaeus (Gorse) and Ulex gallii (Western Gorse). Gorse is common over the whole of the county. Western Gorse is much more restricted within the county, often being found on the more heathy ground and acid soils. Zoe Delvin the finder said would I like to go and see a gorse she had found, which from photos we thought could be Ulex minor (Dwarf Gorse), a species that has only once been reported from the county back in 1959.

There were 11 bushes of Ulex x breoganii on the side of a disused railway at Mountelliott, a little north of New Ross. The books all say measure a range of flowers, I did this with flowers from all 11 bushes and could see they better fitted between the two species. Ulex europaeus has blue/green stems and foliage and large strong spines, and pale yellow flowers. Whilst Ulex gallii has dark green foliage and week spines and whole plant much more slender, and golden yellow flowers. Ulex x breoganii is somewhere in the middle, foliage is neither blue/green or dark green and the flowers are a deep yellow but not as golden as Ulex gallii. To be sure we sent photos to Jeanne Webb who is very familiar with the hybrid and Jeanne agreed with our ID.

Calystegia x howittiorum (C. pulchra x C. silvatica) new for Wexford

 Alexis Fitxgerald email me to ask if I knew the hybrid between Calystegia pulchra (Hairy Bindweed) x Calystegia silvatica (Large Bindweed) = Calystegia x howittiorum - that day I didn't. The next day I was driving along in Wexford and saw the above pink flowered bindweed in a roadside hedge, I stopped to get a map reference. On looking at the plant I could see it wasn't C. pulchra as I had expected but the hybrid C. x howittiorum. The next day I stopped to look at a known site for C. pulchra, and again it was the hybrid. The hybrid has never been recorded form Wexford before. The hybrid has pink flowers, bracteoles (see photos below) near to Calystegia silvatica subsp. disjuncta, plus the pedicel has a wavy-edged wing (see photo below) like C. pulchra.

Pastinaca sativa subsp. urens (Eastern Parsnip) a new parsnip for Ireland

 After reading Alan Leslie's article on 'An overlooked parsnip in Britain' in BSBI News No. 134 January 2017, I started to wonder if the parsnip at Rosslare Ferryport could also be Pastinaca sativa subsp. urens (Eastern Parsnip). I had to wait until it flowered. A specimen was sent to Alan and he agreed it was Eastern Parsnip. This new parsnip has sort of a round stem, but has no deep grooves and ridge like the other subsp. have. Also the terminal umbel on Eastern Parsnip is the same size as all the other heads on the same plant. The bottom picture shows a large patch of the Eastern Parsnip on a bank by all the parked new cars and vans. The area has just been fenced in, much harder now to gain access.

Erica erigena (Irish Heath) on a Wexford heath, a new county record

 I was doing some recording on a heath on Bargy Common when I came across this Erica which I took to be a garden species. I tried keying it out and only came up with Irish Heath. Sent a specimen to Charles Nelson who agreed with my ID. Charles said it is grown in gardens. All the other sites in Ireland are in the North-west. Wexford is the opposite corner. Couldn't see it in any gardens nearby. Will be interesting to see if it spreads.

Tragopogon porrifolius (Salsify) 2nd Wexford record

 Was checking out sites where I saw Dactylorhiza leaves earlier in the year, this morning before the rain got the better of me. Stopped quickly at a monad which I had visited early in the year to add some grasses to the recording card. Very surprised to see a group of Salsify flowering on the roadside at Castlellis. This is the 2nd county record. I wonder if I had seen it when the flowers were closed up if I would have recorded it as Tragopogon pratensis (Goat's-beard)!

Luzula multiflora subsp. hibernica

 It was good to find lots of Luzula multiflora subsp. hibernica an Irish endemic today in the centre of a track leading to a disused quarry at Burrow very close to the Wicklow border. This is only the 4th record for the county. It is a much slender plant than Luzula multiflora subsp. congesta. It is more like a hybrid between Luzula campestris (Field Wood-rush) and Luzula multiflora (Heath Wood-rush) as it looks some where half way between the two species. Had to measure the seed appendage, all less than 0.3mm in length. The whole plant isn't as big or as hairy as Luzula multiflora subsp. congesta.

Trifolium ornithopodioides (Bird's-foot Clover) a new site on the south coast

 Bird's-foot Clover is a rare clover in Wexford. Very surprised today to find a new site at Bannow. 15 km from the nearest site on the south coast. I had walked over the clover twice before I noticed it on the bare gravel. There were 58 clumps. Bird's-foot Clover is very easy to over look as it looks like a small patch of non-flowering White Clover, has much smaller leaves. The flowers are very tiny and it is easy not to even notice them. A great find from a place I have been to a number of times over the years.

 Below is the habitat the clover was found in.
