all "BIEN_taxonomy_*()" queries list class as "Equisetopsida" about rbien HOT 3 OPEN

Thanks for the note! This issue is related to taxonomic lags. The higher classification used by Tropicos (and the TNRS, hence BIEN) at the time of our last update followed Reveal and Chase 2009 in applying the Equisetopsida to all land plants, not just horsetails. Horsetails are now known to be nested in the ferns. @ojalaquellueva will this issue be addressed in the forthcoming update to BIEN?

@bmaitner correct. The TNRS classification is taken straight from Tropicos, which follows APG III (Reveal and Chase 2009) in placing all land plants in class Equisetopsida. It will take some fiddling to change that as Tropicos still hasn't changed their higher taxonomic backbone. Most likely I'll make the World Flora Online (WFO) backbone the default higher classification and keep Tropicos as an alternative.

@bmaitner I suggest closing this issue as there is no problem here. It is just the classification used, which is fine. I may switch to a different higher classification with the next rebuild and we can revisit this discussion then.
