spinescent; leaves alternate; flowers precocious, at base of short 
lateral twigs simulating catkins ; males sessile in axils of deciduous 
bracts; females solitary pedicellate, in axils of leaves (Europe, tem-

rarely 4, 6), rotundate concave imbricated deciduous leaves ; leaves 
of innermost whorl 5 (or 4, 6), long subspathulate, crispato-crenate
