Ditrichum flexicaule

Following George's photos of Ditrichum gracile from Cefn-onn, here are a couple of pics of D. flexicaule sensu stricto from the tops of limestone boulders at Craig y Cilau.  The lower photo shows the characteristic branches with short, imbricate leaves - D. gracile doesn't have these.  There are problematic intermediates though, and a widespread feeling among British bryologists that this isn't the safest of splits.
