inhabits the fringe of a deciduous tree forest where the new green
above covers up in mid-late spring. Appearing from underground in
late February, F. ayakoana flowers in March and dies back in
late May. That is why they call this a spring ephemeral. This
species is endemic to Shimane, and the Red Data Book lists it as a
CR+EN. The flower (a set of sepals) is a cup-shaped campanulate and
has a striking nectary on each tepal, a few millimeters apart from
the base, which identifies this species.
