Leaves The contemporary taxa in a dataset (as opposed to the reconstructed ancestral taxa).  Also known as terminal tips.

LogDet A distance matrix method, simultaneously invented by Mike Steel and James Lake. This method is particularly adept at reconstructing relationships among sequences that have evolved by a non-homogenous (in relation to base composition) process. Also known as Paralinear distances.
