Habitat in Europa media et boreali ; specimina Gallica spontanea 

 baud vidimus; hospitatur autem in hortis ac arboretis, e. g. circa 

 Parisios in ambulacris sylvee Bois de Boulogne dictse. 



B. Nux lignosa : costis valde prominulis. Ramuli junior es, petioli ac 

 foliorum pagina inferior plus minusve hirti.
