Sylvanus Wear formed the core of the Belfast Field Club.
The flowering plants were his hobby and he undertook the work required to issue a Second Supplement and Summary of the Flora of the North-east of Ireland.
His algal collections were donated by Queen's University of Belfast to the Ulster Museum in 1968.
