Monocots of Berrien County, Michigan

The monocots, short for monocotyledons (Class Liliopsida), are one of two classes of flowering plants, or angiosperms, within the Kingdom Plantae, the other being the dicots, or dicotyledons (Class Magnoliopsida). The major distinguishing features between monocots and dicots are discussed here.

Approximately 27,000 species of monocots are recognized worldwide, of which about 4,500 species occur in North America north of Mexico. According to the Online Atlas of Michigan Plants, 437 (64 percent) of the 678 species of monocots known from Michigan have been found in Berrien County; these 437 species represent 13 orders, 25 families, and 134 genera.

While the showy lilies generally draw the public’s attention, it is the grasses and sedges that dominate the local flora, accounting for 45 percent and 35 percent, respectively, of the monocots of Berrien County.

In the following list, scientific and common names follow the USDA Plants database. Species known to occur in Berrien County only as a result of human Introduction are denoted by [I]. Species for which there is a question as to their Native or Introduced origin are denoted [I?]. The status of species determined to be Special Plants in Michigan are denoted as follows: [T] – Threatened, [SC] – Special Concern, [X] - possibly Extirpated.
