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 colourful 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.
Rhododendron is a genus of 1,024 species of woody plants in the heath family (Ericaceae), either evergreen or deciduous, and found mainly in Asia, although it is also widespread throughout the highlands of the Appalachian Mountains of North America. It is the national flower of Nepal as well as the state flower of West Virginia and Washington in United States, and state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer.
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe or leaf-like bract. Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
Syngonium is a genus of flowering plants in the family Araceae, native to tropical rain forests in southern Mexico, the West Indies, Central and South America. They are woody vines growing to heights of 10–20 m or more in trees. They have leaves that change shape according to the plant's stage of growth, and adult leaf forms are often much more lobed than the juvenile forms usually seen on small house plants. The scientific name of the genus comes from the Greek words σύν and γονή and refers to the fused ovaries of female flowers.
Philodendron is a large genus of flowering plants in the family Araceae. As of September 2015, the World Checklist of Selected Plant Families accepted 489 species; other sources accept different numbers. Regardless of number of species, the genus is the second-largest member of the family Araceae. Taxonomically, the genus Philodendron is still poorly known, with many undescribed species. Many are grown as ornamental and indoor plants. The name derives from the Greek words philo- or "love, affection" and dendron or "tree". They are commonly called by their generic name.
The NASA Clean Air Study was a project led by the National Aeronautics and Space Administration (NASA) in association with the Associated Landscape Contractors of America (ALCA) to research ways to clean the air in space stations. Its results suggested that, in addition to absorbing carbon dioxide and releasing oxygen through photosynthesis, certain common indoor plants may also provide a natural way of removing volatile organic pollutants.
Pinguicula moranensis is a perennial rosette-forming insectivorous herb native to Mexico and Guatemala. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 10 centimeters (4 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single pink, purple, or violet flowers appear twice a year on upright stalks up to 25 centimeters long.
Allium nigrum, common name black garlic, broad-leaved leek, or broadleaf garlic, is a Middle Eastern species of wild onion. It lacks the onion or garlic scent shared by most of the other species in the group. The species is native to Turkey, Cyprus, Syria, Lebanon, and Israel but cultivated as an ornamental in many other places. It has become naturalized in some regions, including parts of the United States.
Astragalus lemmonii, the Lemmon's milkvetch, is a rare plant of eastern California. It is a member of the bean family, the Leguminosae, and specifically a member of the subfamily Papilionoideae. The genus Astragalus is a large genus within this family; members of this genus are known as milkvetches or locoweeds. Close relatives of this particular species include Astragalus peckii and Astragalus lentiformis.
Philodendron hederaceum is a species of flowering plant in the family Araceae, native to Central America and the Caribbean.

Philodendron crassinervium is a species of plant in the family Araceae.
Philodendron bipinnatifidum is a plant that belongs to the family Araceae and subgenus Meconostigma, one of three subgenera within the genus Philodendron. The commonly used name Philodendron selloum is a synonym. This plant is native to South America, namely to Brazil, Bolivia, Argentina, and Paraguay, but is also cultivated as a landscape plant in tropical, subtropical and warm temperate climates.
Silvanidae, "silvan flat bark beetles", is a family of beetles in the superfamily Cucujoidea, consisting of 58 described genera and about 500 described species. The family is represented on all continents except Antarctica, and is most diverse at both the generic and species levels in the Old World tropics.
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous flowering plants in the monocot order Asparagales. The family takes its name from the genus Amaryllis and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae).
Phylloxeridae is a small family of plant-parasitic hemipterans closely related to aphids with only 75 described species. This group comprises two subfamilies and 11 genera with one that is fossil. The genus type is Phylloxera. The Phylloxeridae species are usually called Phylloxerans or Phylloxerids.
Syngonium podophyllum is a species of aroid, and commonly cultivated as a houseplant. Common names include: arrowhead plant, arrowhead vine, arrowhead philodendron, goosefoot, African evergreen, and American evergreen. The species is native to a wide region of Latin America from Mexico to Bolivia, and naturalized in the West Indies, Florida, Texas, Hawaii, and other places.
Philodendron xanadu is a plant that belongs to the family Araceae and subgenus Meconostigma, one of three subgenera within the genus Philodendron. This plant is native to Brazil, but is widely cultivated as a landscape plant in tropical, subtropical and warm temperate climates.
Allioideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. It was formerly treated as a separate family, Alliaceae. The subfamily name is derived from the generic name of the type genus, Allium. It is composed of about 18 genera.
Philodendron appendiculatum, also known as güembé, is a perennial species in the genus Philodendron, belonging to the family Araceae. It lives in the jungles, wetlands, and moist forests of South America.
