The small, stalkless leaves of Erica glandulosa subsp. fourcadei grow in fours up the stems.
The young leaves have more of the sparse glandular hairs characterising the plant than older leaves. The hairs seem to be more concentrated along the rolled-under margins of the barrel-shaped leaves that change their green shades to darker ones with age.
Hairiness on the pale stem in picture is denser than on the leaves (Baker and Oliver, 1967; iNaturalist; http://pza.sanbi.org).
