Careful, such sites tend to have been compiled in haste and are meant as an
indication only, not as a source. Since there was a publication in the Bot.
Journ. Linn. Soc. of last year (and before that too) it may be easier to
browse through the list of references there?

Also, descriptions of the characters of higher taxa are not always
correct in every character for all subordinate taxa.
