Abstract:
F. sulcisquamosa is slightly different from F. unibracteata in pollen morphology and
differs external-morphologically from the latter in lacking trellised spots inside tepals. There-
fore the former is reduced to a variety of the latter. F. puqiensis is found very similar to
F. thunbergii both in pollen morphology and gross morphology. The former is different from
the latter in geographical distribution and thus reduced to a variety of the latter.
