Another example of narrow-leaved glossy buckthorn. This condition is not infrequent. "Two horticultural forms of Frangula alnus are widely sold and planted in North America. The cultivar 'Asplenifolia' (Frangula alnus var. asplenifolia Dippel; fernleaf or cutleaf buckthorn) has linear-oblong leaves with coarsely toothed to incised margins and commonly is grown as a specialty plant."--Flora of North America
