Osmorhiza chilensis and Osmorhiza depauperata are wispy, very delicate plants easily over-looked even though they are very common.  They grow singly, as in this picture, or in large colonies lining trails. Tiny white flowers are grouped in equally tiny sprays.  These give way to long, very narrow seed pods.

The most recent botanical classification eliminates O. chilensis and splits it into three species, one of which is combined with O. depauperata. 

Stems , leaves, seeds, and especially roots of Sweet Cicely often have a pleasant anise flavor and aroma, thus its Greek genus name: "osmo" for "smell" and "rhiza" for "root".  "Chilensis" is for the country of Chile where the plant was first collected in the late 1820s.  "Depauperata", "diminutive", perhaps refers to Sweet Cicely’s very delicate, fragile form and tiny flowers.

Even though the most recent botanical classification combines Osmorhiza chilensis with Osmorhiza depauperata, there are variations that are interesting to observe: the Osmorhiza chilensis flowers and seeds are in a compact spray, i.e., the pedicel (the individual flower stem) of each flower makes about a 30 degree angle with the peduncle (the stem of the entire flower cluster).  Osmorhiza depauperata flowers and seeds spread nearly at right angles to the main flower stem (see especially the last seed photograph of O. depauperata).  Seeds of O. chilensis are nearly cylindrical; seeds of O. depauperata are club-shaped.  Otherwise the plants are almost identical in appearance.

The Osmorhiza occidentalis flower is so tiny and so spread on long stems that it is easily overlooked. Leaves are pointed and serrated; stems are thick and swaying.  Osmorhiza occidentalis can occur singly in open dry woods or in very large patches in moist woods.  Compare this Sweet Cicely to its even more common close relatives, Osmorhiza depauperata and Osmorhiza chilensis above.

Stems , leaves, seeds, and roots of Sweet Cicely often have a pleasant anise flavor and aroma, thus its Greek genus name: "osmo" for "smell" and "rhiza" for "root". "Occidentalis" is Latin for "Western".

Thomas Nuttall collected the first specimen of this plant in what is now Oregon in the early 1830s. He named it Glycosma occidentalis in 1840 and it was given its present name by John Torrey in 1858.
