Maianthemum paniculatum is a perennial flowering plant; a species of monocot found from Mexico to Panama.

[1][2] Smaller plants from Chiapas, Mexico, with narrow rhizomes and 10 or fewer stem leaves have been treated as Maianthemum septifolium.

About 8 to 15 spreading to ascending side branches are set at 4–20 mm intervals along the main axis of the panicle.

[4] The flowers are made up of white, spreading tepals 2–42 mm long that are roughly equal in size.

[4] Maianthemum paniculatum has been found in Costa Rica, El Salvador, Guatemala, Honduras, and Panamá as well as the Mexican states of Chiapas, Guerrero, Hidalgo, Oaxaca, Puebla and Veracruz.
