updated taxon framework relationship

Summary of changes:

T. breviflorum --> H. breviflorum
T. fraseri --> H. fraseri
T. japonicum --> H. fauriei
T. tubulosum--> H. tubulosum
T. virginicum --> H. virginicum
T. walteri --> H. walteri
Triadenum (genus) --> Hypericum sect. Elodea

Weakley 2018 (citing Nürk et al. 2013) and VASCAN (citing FNA in prep) include Triadenum within Hypericum. Per Rafaël Govaerts (Feb 2019), Plants of the World Online will also be updated soon to include it within Hypericum. Sums up some research lumping it in Hypericum: Robson, N. (2016). And then came molecular phylogenetics—Reactions to a monographic study of Hypericum (Hypericaceae). Phytotaxa, 255(3), 181. doi:10.11646/phytotaxa.255.3.1.

My main question is what to do about #7, i.e. IDs of Triadenum (genus), and the ~100 observations of Triadenum at rank=genus? Merge to H. sect. Elodea?

Sounds good to me. I agree Triadenum (genus) should = Hypericum sect. Elodea

whoa!

agree with #7 (merge genus-level obs to section)--it's fairly common to have obs. where I can't distinguish virginicum & walteri because I can't see calyx lobes etc. Having useful ranks between genus & species is good!

likewise with fraseri and virginicum. I have lots to genus where i can't tell those apart.
