Bare tree growing through centre is Rowan

Widespread but sporadic among rocks or heather, often on clifftops or in mountain boulder fields, but sometimes choosing a sheltered spot.

Leaves c 5-20 mm long.  Berry c 5-6 mm long.

ID: Leaves in whorls of 3 with a whitish stripe along the upper surface.

Other features: Flowers in May-June, male and female on separate plants, female develop into berries, which remain green for a year or so then ripen to become blue-black.

Two subspecies occur, nana and communis.  Nana is a prostrate form, and is the commoner in the area, growing in more exposed places.  Communis is upright but bushy.  Intermediates  occur.  Nana also has a pure white line along the leaf (greyish in communis), leaves almost blunt (spiny in communis) and leaves about 4-7 x as long as wide (8-16 in communis)

Same plant as in top picture, growing among sheltered riverside rocks.  As this plant was 1 m tall from base to highest point, it is presumably ssp communis.  Will go back and check one day and get better pics.
