I agree with Jerry. The statement is that the author recognises the taxon as a component of the taxon hierarchical level within which it is incertae sedis, but cannot place it within any of the taxa at the next heirarchical level below. This may be interpreted as a statement about the absence of data regarding the incertae sedis taxon, or, indeed, a statement that the totality of the circumscriptions of the taxa at the next lowest rank are in their current form insufficient to encompass the full variation within the higher taxon.

All,
I'm not sure I agree with this simplistic interpretaion of incertae sedis. I thought it meant
the author could not place it in any of the existing named higher ranks in his circumscription of the taxon (which incorporates a concept of the higher classification). e.g. that none of the existing families in a particular classification he wishes to adopt is suitable for his taxon. Thus incertae sedis carries concept information, as does any component of the higher classification applied to a taxon. In my opinion it is a necessary statement about the absence of information and not just a lack of data.

For what it's worth, I feel the same as Rich on this. The TCS should not
attempt to be a vehicle for transfer of all information in a taxonomic
document - only of that which can in some way be used.

Ah!! I now have a glimmer of understanding! If the purpose is simply to
record the fact that the author used the term "incertae sedis" in the
publication, then I do not consider this information important for purposes
of TCS, because it does not help us understand anything about the Concept
definition, or relationships to other concepts. There are many other kinds
of information that authors include with their use of names and concepts,
which are not included in TCS.
Aloha,
Rich
