Topic: Taxonomy problem
Hi Chris
Not sure if this is one for you or not, but as you can see from this post http://forums.nbn.org.uk/viewtopic.php? … 73#p20773. There is an omission in the R6 version of the dictionary right at the top of the vascular plants list.
Currently in the R6 dictionary browser the top level classes of vascular plants appear as
Chlorophyta
Lycopodiophyta
Equisetophyta
Pteridophyta
Ginkophyta
Coniferophyta
Magnoliophyta
Mike tell us that Coniferophyta is now obsolete and that its child taxon Pinopsida now refers up to the overarching Trachyophyta (which is currently in the list of additional names) as should all the other classes above except Chlorophyta.
As it happens they all do, except Pteridophyta, so using Tracheophyta as the root for a query of our database currently excludes the ferns from the output result (in our database this is 11,000 records gone astray).
