Remarks :

The Maltese material seems to correspond morphologically and genetically with the hybrid between B. glaucus and B. maritimus, and at present this is assumed to be an endmic hybrid. Sterility, polymorphism and intermediate characters of the achenes between the putative hybrids strongly supports this hybrid. Check paper in the links below It will be formerly described in 2023.
