Poculiforms Known since the nineteenth century, poculiform snowdrops derive their name from the Latin poculus ('little cup'), and were named by the Revd. Henry Harpur-Crew (1828–1883). The inner segments are elongated so that all six flower segments are generally equal in length, forming a rounded, bowl-shaped flower.

We discuss the possibility that one stygobitic lineage secondarily regained some of its body pigmentation as adaptation to increased photic conditions after cave collapse and forming of cenotes during the last glacial maximum.
