During my internship here at Leeds Museum Discovery Centre I have been helping to complete a photographic record of Thomas Cockerline’s herbarium collection. Throughout this I came across two specimens that particularly interested me, a Vicia bithynica specimen and an Epilobium pedunculare specimen.
Vicia bithynica (Bithynian Vetch) is and has been for some time a rare and declining species of legume. It is a scrambling annual found in rough grassland on coastal under-cliffs and inland in open hedges, scrubby grassland and on railway banks. The flowers are a beautiful purple with white wings and keel and this plant has distinctive toothed stipules (leaf-like structures at the bottom of the leaf stalk or petiole).
I did find some excellent news online from the UK wild Flowers website, where someone has recorded (2005) a relatively large population of Vicia bithynica on a hillside by the sea at Upgang Ravine.
The other herbarium specimen that interested me was of the species Epilobium pedunculare, native to New Zealand but thriving in the British Isles, to the extent it is often referred to as a ‘garden thug’. This ‘little foreigner’ is considered a weed, but we have only ourselves to blame for its invasion into our countryside via dispersal of seeds from our gardens.
This species is excellently adapted to the British climate and as stated in the issue ‘The Naturalist’ from Oct-Dec 1947, it has a preference for wilder places amongst the hills and moor-lands and is also commonly found growing amongst Sedges.
