Taxonomy

In the APG III system, the genus is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It was formerly placed in its own family Convallariaceae, and, like many lilioid monocots, before that in the lily family Liliaceae.

There are three varieties that have sometimes been separated out as distinct species or subspecies by some botanists.

Convallaria transcaucasica is recognised as a distinct species by some authorities, while the species formerly called Convallaria japonica is now classified as Ophiopogon japonicus.
