  In tree shown in Figure \ref{fig:Tree1} (genus _Brachybacterium_), our sample of interest from an assembly is "Brachybacterium muris UCD-AY4" \cite{Lo\_2013}. It falls within a clade where every named member has the same name "Brachybacterium muris", and this name does not occur elsewhere on the tree. Hence, we were confident enough to name our sample as that species. In other words, this sequence falls within a well-supported monophyletic clade of _Brachybacterium muris_.    In the tree shown in Figure \ref{fig:Tree2} (genus _Tatumella_) our species of interest is Tatumella _Tatumella_  sp. \cite{Bendiks_2013}. In contrast to the Brachybacterium example, here our species falls within a poorly defined clade containing multiple species. In this case we did not assign a species name to this isolate.
