What does this tree mean?

Background

This leaflet was produced by the National Union of Women's Suffrage Societies (NUWSS) in July 1913.

The NUWSS adopted a peaceful and non-confrontational approach. Members believed that success could be gained by argument and education. The organisation tried to raise its profile peacefully with posters, leaflets, calendars and public meetings.
