Joanna kindly spent some of her holiday on Skye recording tetrad NG24K which only had 3 species recorded previously. It now has 121. She also spotted this fine Vicia orobus (Wood Bitter-vetch) near Roag.

Does anybody know what this is? Later: Consensus is Nostoc sp. There is lots about at the moment:


Three interesting (to me, anyway) papers that have come to my attention recently, though only one is recent work:

  1. All English Elm trees could be descended from a single tree brought here by the Romans (2004)
  2. Yeast emerges as hidden third partner in lichen symbiosis (2016)
  3. Researchers at Royal Botanical Gardens, Kew now believe there are hundreds more plants that catch and eat insects and other small animals than they previously realised. Among them are species of petunia, ornamental tobacco plants, potatoes and tomatoes and shepherd’s purse (2009)

    Hi Stephen, I suspect your last picture is of a cyanobacterium, probably a Nostoc species.

    Many thanks!
