Descendants / monophyly on unrooted trees?

is there a way to determine taxa that are outside the maximally inclusive monophyletic group in an unrooted tree, maybe by making some assumptions about distances?

Not clear what you mean here. Maximally inclusive according to what criteria? Could you provide either an example function template or toy example of what it would do?

I have a function that will find the node of a maximally inclusive clade (add 0.75 per added in-group, subtract 1 for added out-group, so it will add two in-group taxa if that means adding in one outgroup taxon). But not clear how directionality of daughter taxa is determined for a node on an unrooted tree. Don't want to have the 'inside out" tree...
