Only on mountains, where it can be commoner than E nigrum in high altitude dwarf heath vegetation.

Flower diameter c 1.2-2 mm, berries c 4-10 mm

ID:  (E nigrum agg) 6 separate (not joined at base) pink petals/sepals.  Leaf-margins rolled under to almost meet below.  Also unmistakable in fruit if looks like these pictures.  (E hermaphroditum) Leaves 2-3 times as long as broad, not 3-4 times.  Young twigs green, not red.  Flowers always hermaphrodite.  Stems never root.

Other features: Hermaphrodite character can often be seen in fruiting plants since the withered stamens persist at the base of some of the berries.
