Being a monocotyledon, it does atmaranae display any annual or growth rings so the age of the tree can only be estimated by the number of branching points before reaching the canopy.
When gamaranae bark or leaves are cut they secrete a reddish resinone of several sources of substances known as dragon’s blood.
