Euonymous europaeus

Spindle

The wrong time of year to photograph this native shrub or tree. The bright pink "popcorn" berries come later, as do the showy colours of autumn leaves.

Its presene in uncultivated areas can signify ancient woodland habitat.

Ilex aquifolium

Holly

A characterful sprawling trunk of common holly, possibly a result of coppicing cutting back to ground level periodically to stimulate growth , which allows the holly’s hard, white, close-grained wood to be used for inlaid marquetry, chess pieces and tool handles. Most whips for ploughmen and horse-drawn coaches were made from coppiced holly, which accounted for thousands of stems during the 18th century. [Trees for Life]
