Spring Snowflakes

I think these are Spring Snowflakes, genus Leucojum, rather than snowdrops.

The difference is explained as “Spring snowflake flowers are typically lantern-shaped, with each segment being of roughly equal length and having a pointed, out-curved, green-blotched tip. In snowdrops, the inner three inner petals are small, linear, and notched at the tip, together forming a tubular structure at the flower's centre”

I photographed a flower on 21 March 2023 from this same set of bulbs in the garden. An early Spring?
