Maianthemum includes the former genus Smilacina and is a genus of perennial herbaceous flowering plant with fleshy, persistent rhizomes. It is widespread across much of North America, Europe and Asia, and may be terrestrial, aquatic or epiphytic. It is characterized by simple, unbranched stems that are upright, leaning or hanging down and have 2-17 foliage leaves. Leaves are simple and may clasp the stem or be short-petiolate. The inflorescence is terminal and either a panicle or a raceme with few to many pedicelate flowers. Most species have 6 tepals and 6 stamens; a few have parts in 4s. Tepals are distinct in most species and all of similar size. Flowers are spreading, cup-shaped or bell-shaped and usually white, but lavender to red or green in some species. Fruits are rounded to lobed berries containing few to several seeds.

Asplenium resiliens, the blackstem spleenwort or little ebony spleenwort, is a species of fern native to the Western Hemisphere, ranging from the southern United States south to Uruguay, including parts of the Caribbean. Found on limestone substrates, it is named for its distinctive purplish-black stipe and rachis. A triploid, it is incapable of sexual reproduction and produces spores apogamously. First described by Martens and Galeotti in 1842 under the previously used name Asplenium parvulum, the species was given its current, valid name by Kunze in 1844. Several similar species are known from the tropics; A. resiliens may have arisen from these species by reticulate evolution, but precise relationships among the group are not yet certain.
