Mayflower (Maianthemum)

Description

Maianthemum (Latin M-ia "May" and Greek -nthemon "flower"; including former Smilacina) is a genus of rhizomatous, herbaceous, perennial flowering plants, native to the understory of woodlands. It is widespread across much of North America, Europe and Asia. In the APG III classification system, Maianthemum is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). Because of genetic similarity, similar fruits, and evidence that the 4-tepal species evolved from a 6-tepal species, the genus Smilacina was combined with Maianthemum in the late 20th century. Like many lilioid monocots, both Maianthemum and Smilacina were formerly included in the family Liliaceae. The genus has also been placed in the former family Convallariaceae, and resembles the closely related Polygonatum, hence the common name "false Solomon's seal". Flowers have six tepals, reduced to four in M. canadense, M. bifolium and M. dilatatum.
