|Shining Crane's-bill Geranium lucidum and Herb-Robert G. robertianum
In the past a hybrid between G. lucidum and G. robertianum was said to have been found at 'Mill in the Hole', Bridgnorth, Salop (Daniels Mill). This hybrid is not mentioned in the Hybrid Flora of the British Isles (Stace, 2015), but was mentioned in Stace 1975 by McClintock when it was said to be in a couple of places. There is some uncertainty around the validity of the record due to the lack of a convincing herbarium specimen.
Michael Wilcox, BSBI member has been researching Geranium lucidum and has asked Shropshire botanists to keep an eye out for unusual looking specimens that could indicate hybridisation. Michael would welcome flowering specimens of G. lucidum to look at pollen and stomata, and would want to receive live specimens of plants with flowers/flower buds and some root (they are shallow rooted so should be possible). Please exercise the usual protocol for collecting specimens (BSBI Code of Conduct), and contact Michael beforehand: Michaelpw22@hotmail.com
So this is your mission, keep an eye out for odd looking G.lucidum whilst you are out and about, and especially if you are visiting the rather fine looking Daniels Mill near Bridgnorth as it is now known:
