Beaucarnea is a genus of flowering plants native to Mexico and Central America. [2] In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae [3] ). Beaucarnea is sometimes treated as a synonym of the genus Nolina , with the species being then transferred to that genus. However, recent research shows that Beaucarnea should be treated as an independent genus. [4]
The species are small tropical xerophytic trees growing to 6–10 m tall, with a trunk 20–40 cm diameter with a flared base; young plants are single-stemmed, branching only after flowering. The leaves are evergreen, linear, strap-shaped, 0.5-1.8 m long and 1.5–2 cm broad, leathery in texture, with a finely serrated margin. The flowers are produced only on old trees, forming on large panicles 75–110 cm long, the individual flowers numerous but very small (1.5 mm diameter), greenish-white, with six tepals.
The now defunct genus Calibanus was first formally described in 1906 by Joseph Nelson Rose, [5] with Calibanus including two species. More recent research using molecular (phylogenetic) and morphological findings demonstrated that both former Calibanus species were closely related to Beaucarnea species, leading to both former Calibanus species being transferred to the genus Beaucarnea.

Asparagales is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985 and then the APG in 1998, 2003 and 2009. Before this, many of its families were assigned to the old order Liliales, a very large order containing almost all monocots with colorful tepals and lacking starch in their endosperm. DNA sequence analysis indicated that many of the taxa previously included in Liliales should actually be redistributed over three orders, Liliales, Asparagales, and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. In the APG circumscription, Asparagales is the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species.
Scilla is a genus of about 30 to 80 species of bulb-forming perennial herbaceous plants in the family Asparagaceae, subfamily Scilloideae. Sometimes called the squills in English, they are native to woodlands, subalpine meadows, and seashores throughout Europe, Africa and the Middle East. A few species are also naturalized in Australasia and North America. Their flowers are usually blue, but white, pink, and purple types are known; most flower in early spring, but a few are autumn-flowering. Several Scilla species are valued as ornamental garden plants.
Nolina is a genus of tropical xerophytic flowering plants belonging to the Asparagaceae plant family. The native distribution of the genus includes most of Mexico and the southern regions of the United States. Especially in the USA, members of the genus are known as beargrasses, some of which are cultivated as ornamental plants.
Scilloideae is a subfamily of bulbous plants within the family Asparagaceae. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus Hyacinthus. Scilloideae or Hyacinthaceae include many familiar garden plants such as Hyacinthus (hyacinths), Hyacinthoides (bluebells), Muscari and Scilla and Puschkinia. Some are important as cut flowers.
Nolinoideae is a monocot subfamily of the family Asparagaceae in the APG III system of 2009. It used to be treated as a separate family, Ruscaceae s.l. The family name is derived from the generic name of the type genus, Nolina.
Agave amica, formerly Polianthes tuberosa, the tuberose, is a perennial plant in the family Asparagaceae, subfamily Agavoideae, extracts of which are used as a note in perfumery. Now widely grown as an ornamental plant, the species is native to Mexico.
Asphodelaceae is a family of flowering plants in the order Asparagales. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species. The type genus is Asphodelus.
In 1984, the International Organization for Succulent Plant Study set up a working party, now called the International Cactaceae Systematics Group, to produce a consensus classification of the cactus family, down to the level of genus. Their classification has been used as the basis for systems published since the mid-1990s. Treatments in the 21st century have generally divided the family into around 125–130 genera and 1,400–1,500 species, which are then arranged in a number of tribes and subfamilies. However, subsequent molecular phylogenetic studies have shown that a very high proportion of the higher taxa are not monophyletic, i.e. they do not contain all of the descendants of a common ancestor. As of August 2023, the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010.
Asparagaceae, known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, Asparagus officinalis. This family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, and hosta, and the houseplants include snake plant, corn cane, spider plant, and plumosus fern.
Cascabela is a genus of flowering plants in the dogbane family, Apocynaceae. It is native to Mexico, Central America, and South America.
Lysiphyllum is a genus of flowering plants in the legume family, Fabaceae. It includes nine species of trees, semi-scandent shrubs, and lianas which range from India through Southeast Asia to Australasia. Typical habitats include seasonally-dry tropical forest and woodland, vine thickets, Brigalow and Gidgee scrubland, floodplains, alluvial flats, tidal forest, mangroves, river and stream banks, and occasionally dunes and coral islets. They can grow on diverse soils including calcareous, granitic, and basaltic.
Calibanus was a genus of two species of flowering plants, both evergreen succulents from dry areas of northeastern Mexico.The genus was subsumed in the genus Beaucarnea in the year 2014. The APG III classification system places Beaucarnea in the family Asparagaceae, subfamily Nolinoideae The now-defunct Calibanus was formerly included in the Agavaceae but was separated from them, for it is polycarpic and dioecious. Its name refers to the monster Caliban, an antagonist in Shakespeare's The Tempest.
The Hylocereeae are a tribe of cacti. Most are found in the tropical forests of Central and northern South America, and are climbers or epiphytes, unlike most cacti. The tribe includes between six and eight genera in different circumscriptions. The plants known as "epiphyllum hybrids" or "epiphyllums", widely grown for their flowers, are hybrids of species within this tribe, particularly Disocactus, Pseudorhipsalis and Selenicereus, less often Epiphyllum, in spite of the common name.
Beaucarnea gracilis is a species of flowering plant in the Asparagaceae family. It is native to Puebla, and northern parts of Oaxaca, in Mexico, where it is endemic to the Tehuacán Valley matorral. It grows primarily in the seasonally dry tropical biome.
Beaucarnea glassiana is a species of flowering plant belonging to the genus Beaucarnea, which is a member of the Asparagaceae family. Beaucarnea glassiana forms a caudex geophyte and is native to the Mexican state of Guanajuato where it grows in areas of tropical deciduous forest and submontane central Mexican matorral in the Sierra Madre Oriental near Xichú.
Daniel Lee Nickrent is an American botanist, working in plant evolutionary biology, including the subdisciplines of genomics, phylogenetics, systematics, population genetics, and taxonomy. A major focus has been parasitic flowering plants, particularly of the sandalwood order (Santalales). His interest in photographic documentation and photographic databases has led to several photographic databases including Parasitic Plant Connection, Phytoimages, Plant Checklist for the Rocky Mountain National Park, and Plant Checklist for the Crab Orchard National Wildlife Refuge.
Epiphyllum hookeri is a species of climbing cactus in the Epiphyllum genus. It forms showy white flowers and is native from Mexico through Central America to Venezuela. A perennial, it was introduced to Florida and some West Indian islands.
Gonolobus naturalistae is a species of perennial vine in the milkweed genus Gonolobus. It is endemic to Mexico.
Beaucarnea olsonii is a plant in the family Asparagaceae, native to Mexico. The species is named for the botanist Mark E. Olson.
