Note:
Fagopyrum wenchuanense
was confirmed as a diploid with 16 metacentric chromosomes; based on ISSR data
F. wenchuanense
grouped with
F. qiangcai
;
F. wenchuanense
was considered a derived species from
F. gracilipes
based on the assumption that "reducing ploidy level is one of the possible evolutionary mechanisms in buckwheat"

Note:
it examined affinities among 11
Fagopyrum
taxa including
F. wenchuanense
; broader morphological features of
F. wenchuanense
relates to a member of the "Urophyllum group", but based on its fruit characters it belongs in the "Cymosum group"; both
