Ciao magev Part of the issue is branching overload.
For this kind of thing "working backwards" may help. By which I mean *can you visualise what the tree should look like* at its branchings to be manageable? (E.g. 600 items listed in a Tiddler is likely too much, so WHAT is the SUB-division? 10, 50, 100?). ONE suggestion is to add further levels so that, for instance, genus, is sub-divided in some way ... maybe by morphological features of the plants by genus groups (if possible), or by simple grouped indices on names. In you current thinking the hierarchy is a strict descent line. But there is no reason I can see you could not interlace descriptive or denotative groupings that could make the volume more manageable in its presentation. That's what botanists tend to do in practice in complex situations. The classic "botanical key characteristic identification system" has a lot of utility I think. Just a thought from an amateur botanist :-). Best wishes Josiah -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
