acaroid resin definition

Acaroid resin (also known as accroides) is a heavily colored resin that materializes in both yellow and red forms originating from Australian grass trees.  The resin (gum accroides) contains film-forming characteristics used for years in the processing of orange, red and yellow varnishes.  Acaroid resin continues to be utilized for some industrial uses even though bright dyestuffs have been created to fulfill that particular need in the marketplace.  

Xanthorrhoea, black-boy gum and Botany Bay gum are terms used for resin in the past.
