Ilex crenata - has the common name of the box leaved holly. There are
several varieties and some forms (which have small leaves but are not
shiney box like at al - thinking of I.c f latifolia).
A small green leafed, female variety being Mariesii produces plack
berries.
I.c. Convexa AGM, female, has curved leaves and black berries
I.c. Golden Gem, female, has yellowy / golden leaves with black
berries.
Most of the crenata's produce black berries, but some apparently
produce white or yellow berries; haven't seen them though.
I see that the RHS plant finder lists 35 varieties.
