Topic: List of additional names
Whilst compiling a summary species list for a site (i.e. listing each taxon only once), I noticed that there were two identical entries for Wild Teasel, Dipsacus fullonum.
On further investigation I discovered that while most of the records were recorded against the vascular plants preferred list and some against the Recorder 3.3 list (where the taxon names are synonymous), there was at least one record against an item in the list of additional names. In this list although both common and scientific names are identical with those in the other lists, the item appears with the SppAgg icon.
I am aware that in the past Wild Teazel (now D. fullonum) and Fuller's Teazel (D. sativus) were formerly regarded as subspecies of fullonum and I assume this was the intent of the aggregation. However, if this is the case, then the scientific name should be recorded as D. fullonum agg., or better D. fullonum s.l.
Whatever the case, it makes no sense for two taxa to exist with indistinguishable recommended scientific names, which also share the same incorrect common name. Or more accurately since recorder can distinguish a difference in the intent (since one is marked as SppAgg) it should also make that clear in the names output.
