Maianthemum includes the former genus Smilacina and is a genus of perennial herbaceous flowering plants 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.

The genus is native to warm temperate and subtropical regions of the Northern Hemisphere. They are large ferns, with fronds growing to 50–300 cm long depending on the species. The fossil record of the genus extends to the Paleocene.
Linnaea is a plant genus in the honeysuckle family Caprifoliaceae. Until 2013, the genus included a single species, Linnaea borealis. In 2013, on the basis of molecular phylogenetic evidence, the genus was expanded to include species formerly placed in Abelia, Diabelia, Dipelta, Kolkwitzia and Vesalea. However, this is rejected by the majority of subsequent scientific literature and flora.

Platanus rzedowskii, commonly known as Rzedowski's plane tree, Rzedowski's sycamore, Sicómoro de la Sierra Madre Occidental, or the Sierra Madre Occidental sycamore, is a species of Platanus in the family Platanaceae. It was described by Jackie M. Poole in 2003 with the name attributed to Kevin C. Nixon.
Platanus gentryi, commonly known as Gentry's plane tree, Gentry's sycamore,Sicómoro de la Sierra, or the mountain sycamore, is a species of Platanus in the family Platanaceae. It was described by Kevin C. Nixon and Jackie M. Poole in 2003. The species is endemic to northwestern Mexico, primarily the states of Chihuahua, Sinaloa, and Sonora, at general elevations of 650–1,500 m, where it grows in semi-arid, dry conditions. It is currently listed as "Vulnerable" by the IUCN Red List, for the logging industry has been over-exploiting the species profitable lumber.
