Flowers are spreading, cup-shaped or bell-shaped and usually white, but lavender to red or green in some species. Fruits are rounded to lobed berries containing few to several seeds.

'' has an unusual woody, upright sympodial rhizome set above ground. Roots may be spread along the rhizome, clumped at the nodes, or clumped near the base of leafy shoots. The rhizome is the perennial part of the plant and growth is by branching of the rhizome. Flowering/fruiting shoots are attached to the rhizome by a discreet internode, are short-lived and wither at the end of the growing season. ; Stems and leaves The stems are unbranched and pendant to arching or upright.

'' produces two petiolate foliage leaves the first year, then a flowering shoot the second year with 2-4 sessile leaves. In most species, leaves have a large midvein, dividing the leaves in half, then each half is again divided by a slightly smaller vein; each quarter again divided by progressively finer veins. The resulting pattern is that the leaves have three prominent veins, and adjacent veins are of different diameters. A few species, such as '' Maianthemum stellatum'', have leaves with veins that are often all of roughly the same diameter. Leaf edges may be flat or wavy (undulate) and sometimes have small, outward-pointing teeth.

Taxonomy

The current concept includes species that were previously divided into 2 closely related genera; ''Maianthemum'', including dimerous species and ''Smilacina'' for the trimerous ones. Studies in the 1970s showed strong genetic similarity, similar fruits, and evidence that the 4-tepal species evolved from a 6-tepal species, so the genus ''Smilacina'' was combined with ''Maianthemum''.


Phylogeny

In the APG III classification system, ''Maianthemum'' is placed in the family
Asparagaceae Asparagaceae, known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, ''Asparagus officinalis''. Those who live in the temperate c ...
, subfamily Nolinoideae (formerly the family Ruscaceae). Like many lilioid monocots, ''Maianthemum'' (including the former ''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".


Etymology

''Maianthemum'' comes from the Greek for "May" (maios) and “flower” (Anthos).

Ecology

The majority of species are spring-flowering forest herbs, requiring shaded, moist conditions and cool temperatures. Some however (e.g. '' Maianthemum monteverdense'') are epiphytes. Others such as '' Maianthemum stellatum'' grow in diverse habitats from sand dunes to forest under-stories. And ''

'' are found in full sun in open wetlands. ''M. trifolium'' is sometimes considered aquatic. The species that are forest herbs generally begin growth in early spring, with leaves expanding before the tree canopy fully develops. Epiphytic tropical species usually grow new shoots in the dry season.


Conservation

Many of the North American ''Maianthemum'' are widespread and relatively common. Several though are considered endemic to the wider “Mesomexico”. ''Maianthemum comaltepecense'' is a rare perennial, terrestrial herb found as an understory species in moist forests, known only from Oaxaca, Mexico.Espejo et al.1996. Maianthemum comaltepecense, Una Nueva Especie del Estado de Oaxaca. Acta Botánica Mexicana (1996), 36:21-28 and endemic to southwest Mexico.
