Re: Reporting from Rucksack - spurious taxa
I've constructed a rucksack which comprises all the UKBAP/Section 42 "lower plant" species that occur in Wales. For the bryophytes I based the rucksack entries on the preferred bryophyte dictionary. But I've found something odd when I report from the rucksack using the Report Wizard.
Fossombronia foveolata is in the rucksack, Fossombronia incurva is not. As far as I am aware there is not nor has been any synonymy of these two species. If I run a report on the rucksack, ticking the "All Taxa from List" box, I get no records of F. foveolata reported (rightly, because I don't have any) but I DO get a records of F.incurva reported (they were originally input using the Recorder 3.3 list).
If I run a report on F.foveolata only (i.e. not ticking "All Taxa from List") from the rucksack, I get no records of either species (as expected). I get the same result if I report on F. foveolata from the Recorder 3.3 list.
There is a similar issue with Weissias. W. levieri and W.squarrosa are in my rucksack, W.longifolia is not. But if I report ticking "All taxa from List" I get records of W.longifolia as well as records of the two others. In this case though I find that if I report on W.levieri alone I also get W.longifolia (I expect this is all as clear as mud by now). Again, there is no synonymy taht I am aware of involved here.
Does anyone have any idea what might be going on here?
