Herbaceous perennial to 30" high. Leaves in 2 ranks, elliptic, to 6" long and 3" wide, obtuse or rounded at the base, short-acuminate, finely hairy beneath. Stems finely hairy, curved-ascending. Flowers numerous, on very short pedicels, to 1/8" wide, in a pedunculate to sessile terminal panicle; perianth segments up to 2 mm long, shorter than the stamens. Fruit dotted, becoming red at maturity, sometimes spotted with purple but not striped.

Notes

Flowers mid April to late June

Wetland indicator: Facultative upland

Formerly known as Smilacina racemosa (L.) Desf., it has been widely accepted that the two genera be merged based on the "pattern of inflorescence growth". It is also suggested that the proper family is now Ruscaceae. I have not read the paper by LaFrankie proposing the change.

The differences between the two genera appear to include the following:

Smilacina: Tepals 6; stamens 6; anthers ovate; ovary globose; style very short; stigma obscurely 3-lobed

Maianthemum: Tepals 4; stamens 4; anthers introrse; ovary bilocular, with a 2-lobed style
