Maianthemum racemosum, sometimes confused with Maianthemum stellatum (see below) and Streptopus fassettii, can be distinguished by its broader leaves and tassel-like flower cluster.  Although it is rhizomatous, sprouting new plants from lateral underground roots, it tends to grow in fewer numbers than M. stellatum.  Maianthemum racemosum is a common plant in mid-altitude woods, thriving in moist locations where plants often grow quite robust and several feet tall.

Linnaeus named this species Convallaria racemosa in 1753, Desfontaines renamed it Smilacina racemosa in 1807, Weber accepts the name, Maianthemum amplexicaule, and Kartesz calls it Maianthemum racemosum.  (Nuttall named the species Smilacina amplexicaulis in 1834.) 

"Maianthemum" means "May Flower", "racemosum" describes the inflorescence arrangement, and "amplexicaule" describes the "clasping" of the stem by the leaves.

Star Lily is common in the rich moist soils of Aspen woods where it commonly grows in large patches of dozens of plants.  It is especially noticeable on the uphill side of trails arching its tiny star-like flowers downhill toward hikers.

Linnaeus named this species Convallaria stellata in 1753, Desfontaines renamed it Smilacina stellata in 1807, and Link named it Maianthemum stellatum in 1821.

"Stellatum" is Latin for "star".

In more open woods, plants abound.  Flowers are tiny and hard to see unless you are on your hands and knees, but the dozens of arching plants with pointed leaves are easily noticed -- and quite common.

Fresh flowers grow at the tip and ripening fruit (now yellow, but soon to be red), grows in the fading petals at the base of the raceme of flowers.
