Fritillaria
ayakoana inhabits the fringes of deciduous tree forests,
where the new green aboveground cover develops in mid-late
spring. Appearing from underground in late February, F. ayakoana
flowers in March and dies back (withers from the tips of
branches to the roots, leaving roots behind) in late May. That
is why people call it a spring ephemeral. This species is
endemic to Shimane, and its Red Data Book lists it as a CR+EN.
The flower (a set of sepals) is a cup-shaped campanulate
structure with a striking nectary on each tepal, located a few
millimeters from the base, which identifies this species. Bloom
time: March-April.
