Sand

July 8, 2019

I spent a week on Colonsay with five other botanists refreshing my skills in sand dune and sandy soil habitats, amongst other things. An excellent week in which I learnt about several new galls, saw a Small Copper butterfly, which I have never seen on Skye/Raasay and found nice things in the local context like Atriplex laciniata (Frosted Orache) and Orobanche alba (Thyme Broomrape).

I made the most of my refreshed and new skills by going to Canna/Sanday on Saturday. On summer Saturdays it is possible to have over eight hours on the islands by catching the 0730 ferry from Mallaig and leaving Canna on the 1820.

This proved very useful as I re-found 1930s records in the Sanday dunes for Catapodium marinum (Sea Fern-grass) and Trifolium campestre (Hop Trefoil). In both cases these are only the second recent records for the vice-county, the others being on Rum and Eigg respectively.

I also inadvertently made the first Canna/Sanday record and therefore the first NG20 record for several species including Botrychium lunaria (Moonwort), Carex remota (Remote Sedge) and Scrophularia auriculata (Water Figwort), the last looking like a recent import at the ferry terminal.

Even more importantly, I made the first VC104 record for Polygonum boreale (Northern Knotgrass), distinguished from P. aviculare by having oblong-ovate, petiolate leaves (and large nuts, but it is too early in the year for that to be apparent).

This is a species that was thought to be restricted to the Northern Isles but has since been found in the Outer Isles and Tiree and Colonsay.

The dipteran Janetiella frankumi makes this gall on Rosa spinosissima (Burnet Rose):

Simon showed it to me on Colonsay, and there it was on Canna.

So much more I could write but I must get on with entering records into the database……

To Coire Balaig

June 24, 2019

Today I walked from the Bla Bheinn car park to Coire Balaig. Coire Balaig itself turned out to be pretty dull botanically but on the way there and back I made some useful records. The best from my point of view was Carex pauciflora (Few-flowered Sedge) – two sites with plenty of plants. This had no records in NG52 post-1999 and the previous records were at the opposite (NE) corner of the hectad.

This is difficult to find except when the flowers/fruits are there and they don’t last all that long. Also, it tends to be in the middle of otherwise unexciting wet moor which is not that inviting for careful survey.

On Wednesday, I am off to Colonsay for a week in VC 102.

Hybrid Bluebells

June 23, 2019

There was an interesting paper earlier this year in Conservation Genetics by Peter Hollingsworth and Markus Rusham at RBGE, plus collaborators in Canada and New Zealand, concerning hybridization potential between native and introduced bluebells. Using an experimental array allowing natural pollination to occur among flowering plants, and determining the paternity of offspring using microsatellite markers, they conclude that “lower reproductive success of non-natives coupled with the massive numerical advantage of natives represents a substantial constraint against ‘extinction-by-hybridization’ of H. non-scripta in the UK”. Some good news then.

A Shrub at Skinadin

Steve has spotted this planted shub at Skinadin. Please can ayone tell us what it is?

Later: Mike suggests  Photinia davidiana (Stranvaesia) which looks right to me. I knew it looked familiar……

The Week Just Gone

June 22, 2019

Last Saturday I headed across the Skye Bridge to help out with recording in the adjacent VC105 (W. Ross). Of relevance to my own patch was the finding of Veronica montana (Wood Speedwell) not far from Kyle in NG72 – it is not recorded in NG72 in VC104.

When I got home I broke my laptop. It failed whilst doing a System Restore and I couldn’t even open it in Safe Mode. To cut a long story short, I am now back in business with the same machine but I am trying to buy a new laptop (turns out to be more chaos!).

The upshot of all this is that whilst I have continued to get out and about, computer time has been dedicated to sorting this out rather than writing my blog.

So… back in VC104, fourteen member of Skye Botany Group went to Torrin on Tuesday and re-found Epipactis atrorubens (Dark-red Helleborine) amongst other nice things and added 13 taxa to the well-recorded tetrad NG52Q.

On Wednesday Seth, Neil and I went to Bay and Sgùrr a’ Bhàgh in search of an old record for Paris quadrifolia (Herb-paris). We failed on that but had an excellent day adding  Draba incana (Hoary Whitlowgrass) to the tetrad and finding daffodils on the top of a stack. Heaven knows who thought planting them there was a good idea.

Yesterday I toured a number of sites in Trotternish and re-found Petasites hybridus (Butterbur) at Brogaig, last recorded in 1980 (not tricky given the details from the old record). The Carex diandra (Lesser Tussock-sedge) at Loch Cleat is flourishing. It is in large quantities in the marsh at the west end but also at intervals around the loch:

I found this leaf-spot on Caltha palustris (Marsh-marigold) which I have only seen once before:

Ramularia calthae

There were large numbers of Gymnadenia borealis (Heath Fragrant-orchid) all over the place including road verges.

What Else Has Been Going On

June 14, 2019

Joanna and Julian have had a look at parts of NG60P in Sleat that had not been surveyed before, particularly small areas of woodland. They added nearly 50 taxa to the tetrad including Platanthera chlorantha (Greater Butterfly-orchid) and new to NG60, Carex canescens (White Sedge).

Bridgette re-found the Kalmia procumbens (Trailing Azalea) on An Diallaid. Hoorah!

Les has helped me with some willow issues so that I have settled on Salix x fragilis  (Hybrid Crack-willow) without trying to be too clever for the trees near Borve, confirmed Salix phylicifolia (Tea-leaved Willow) from Kilmauag and sorted out records for Salix x ambigua (S. aurita x repens) that had previously been mis-identified.

A recent specimen with sericeous hairs on young leaves from the S. repens parent:

 

Here on Raasay, Lisa pointed me towards an Acer with curiously purple undersides to the leaves.

It appears to be Sycamore but why it is that colour remains a mystery.

A Lay-by

June 14, 2019

Recently Neil reported Tellima grandiflora (Fringecups) as a garden throw-out from a lay-by in Glen Varragill and said there were other things in the discard pile too. On my way back from Geary I had a look and indeed there were, the most interesting of which is Geranium pyrenaicum (Hedgerow Crane’s-bill).

But there were also local weeds like Arabidopsis thaliana (Thale Cress) and Veronica arvensis (Wall Speedwell). These will presumably not survive for many winters out there.

Geary

June 14, 2019

Yesterday Neil and I went to the Geary Ravine SSSI and then moved south to take in some woodland along the coast in the same tetrad. We got to parts of the Geary Ravine that I had never managed before but still failed to re-find any of the quite long list of things found by John Birks over 45 years ago that have not been recorded since. I suspect as a young man doing his PhD work he got to parts that I never will now.

However, having inspected the Equisetum hyemale (Rough Horsetail) and so on, we moved south to the known site for Neottia nidus-avis (Bird’s-nest Orchid) and found just one:

Nearby, and also a bit further away, we spotted new sites for Cephalanthera longifolia (Narrow-leaved Helleborine), past flowering and sadly not having set any fruits.

We also found Bromopsis ramosa (Hairy-brome), previously recorded from the ravine but not since 1982 and Scrophularia nodosa (Common Figwort) never before recorded from this tetrad but one that had been recorded in NG26 pre-2000 only.

A very useful and enjoyable day, and nobody died.
