Arales is an order of flowering plants. The name was used in the Cronquist system for an order placed in subclass Arecidae, circumscribed as (1981):
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. Also known as the arum family, members are often colloquially known as aroids. This family of 140 genera and about 4,075 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
A raceme or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard and radish plants.
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa.
Heinrich Wilhelm Schott was an Austrian botanist well known for his extensive work on aroids (Araceae).
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, after genus Anthurium. 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". The generic name, Philodendron, is often used as the English name.
The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years : taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets have been elevated to family level. The type genus is Gryllus and the first use of the family name "Gryllidae" was by Walker.
Zantedeschia is a genus of eight species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The genus has been introduced on all continents except Antarctica. Common names include arum lily for Z. aethiopica and calla and calla lily for Z. elliottiana and Z. rehmannii, although members of the genus are neither true lilies of Liliaceae, true Arums, nor true Callas. The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.
Calla is a genus of flowering plant in the family Araceae, containing the single species Calla palustris.
Calla is a genus of flowering plants in the family Araceae.
Hydrometridae is a family of semiaquatic insects, known as marsh treaders or water measurers. They have a characteristic elongated head and body which makes them resemble a yardstick for measuring the water surface.
Zantedeschia elliottiana, golden arum or golden calla lily,yellow calla lily, is a herbaceous ornamental plant in the family Araceae. It grows from a bulb. It is said to occur in the province of Mpumalanga in South Africa, although other sources say that it is not found in the wild but appears to be a hybrid of garden origin.
Zantedeschia rehmannii, the pink arum lily, pink calla, or red calla lily, is a herbaceous ornamental plant in the family Araceae. It is a recipient of the Royal Horticultural Society's Award of Garden Merit.
Gymnostachys is a monotypic genus, of the monocotyledon plant family Araceae.
Aroideae is a subfamily of flowering plants in the family Araceae. It is the largest subfamily in Araceae and consists of about 72 different genera, and 2,300 species. Many Aroideae have spiny pollen grains without a sporopollenin outer exine layer and lacking an aperture.
Orontium aquaticum, sometimes called golden-club, floating arum, never-wets or tawkin, is a species of flowering plants in the family Araceae. It is the single living species in the genus Orontium, which also contains several extinct species described from fossils. O. aquaticum is endemic to the eastern United States and is found growing in ponds, streams, and shallow lakes. It prefers an acidic environment. The leaves are pointed and oval with a water repellent surface. The inflorescence is most notable for having an extremely small almost indistinguishable sheath surrounding the spadix. Very early in the flowering this green sheath withers away leaving only the spadix.
Protarum is a monotypic genus of flowering plants in the family (Araceae). The single species composing the genus is Protarum sechellarum. It is endemic to the Seychelles. This species was previously placed in the subfamily Colocasioideae in the tribe Protareae, but it has since been reclassified to the subfamily Aroideae in the tribe Colocasieae.
Filarum is a monotypic genus of flowering plants in the family Araceae. The single species making up the genus is Filarum manserichense. It is found growing in the amazonian region of northeastern Peru. Govaerts, R. & Frodin, D.G. (2002). World Checklist and Bibliography of Araceae : 1–560. The Board of Trustees of the Royal Botanic Gardens, Kew. The fertile male flowers of Filarum are unique in that they have hairlike attachment to them.
Pothoideae is a subfamily of flowering plants in the family Araceae. The species in the subfamily are true aroids.
