Acis trichophylla, commonly called the triangular-leaved snowflake,[2] is a species of flowering plant in the family Amaryllidaceae, native to Portugal, Spain and Morocco.

There are generally three very narrow leaves per bulb, appearing before the flowers, each leaf being up to 18 cm long but only at most 1 mm wide.

[10] The combination Acis trichophylla was first used in 1830 by George Don, referring to Sweet (he actually used the masculine form trichophyllus).

[11] Although William Herbert in 1837 also placed the species in Acis,[12] most later botanists used the genus Leucojum, treating it as L. trichophyllum Schousb.

It requires protection from frost, and warm dry conditions for a long time in summer, hence growing in an alpine house or bulb frame is recommended.
