The '''arums''' comprise the '''Family Araceae''' (including the numerous '''aroids''' subfamily): [[Monocotyledon|monocotyledonous]] [[flowering plant]]s in which [[flower]]s 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 hood. This family of 107 genera and over 3700 species is most diverse in the New World tropics, although also distributed in the Old World tropics and north temperate regions. Recent genetic research by the [[Angiosperm Phylogeny Group]] has shown that the duckweeds, previously treated in a separate family [[Lemnaceae]], also belong in the Araceae.
In [[Plant sexuality|monoecious]] aroids (possessing separate male and female flowers, but with both flowers present on one plant), the spadix is usually organized with female flowers towards the bottom and male flowers towards the top. In aroids with [[perfect flower]]s the [[stigma (flower)|stigma]] is no longer receptive when the [[pollen]] is released, thus preventing self-[[fertilization]]. There are also some [[Plant sexuality|dioecious]] species.
''[[Anthurium]]'' and ''[[Zantedeschia]]'' are two well-known members of this family, as are ''[[taro|Colocasia esculenta]]'' ([[taro]]) and ''[[Xanthosoma|Xanthosoma roseum]]'' (Elephant ear or ‘ape). Among the largest inflorescence in the world is that of the arum, ''[[Titan arum|Amorphophallus titanum]]'' (Titan arum). This family includes a great many [[ornamental plant]]s: ''[[Dieffenbachia]]'', ''Aglaonema'', ''[[Caladium]]'', ''Nephthys'', and [[Pothos|''Epipremnum'']], to name a few. In the genus ''[[Cryptocoryne]]'' are many popular aquarium plants. Both Taro and ''[[Monstera deliciosa]]'' provide food value (the fruit of ''Monstera deliciosa'' called "Mexican breadfruit"). ''[[Philodendron]]'' is an important plant in the ecosystems of the [[rainforest]]s and is often used in home and interior decorating. ''Symplocarpus foetidus'' ([[skunk cabbage]]) is a common North American species. A interesting peculiarity is that this family includes the largest unbranched inflorescence, that of the [[titan arum]], often erroneously called the "largest flower" and the smallest flowering plant and smallest fruit, found in the duckweed, ''[[Lemnaceae|Wolffia]]''.
Many plants in this family are thermogenic (heat-producing). Their flowers can reach up to 45 degrees Celsius even when the surrounding air temperature is much lower. One reason for this unusually high temperature is to attract insects (usually beetles) to pollinate the plant, rewarding the beetles with heat energy. Another reason is to prevent tissue damage in cold regions. Some examples of thermogenic Araceae are:'' [[Symplocarpus foetidus]]'' (eastern skunk cabbage),'' [[Amorphophallus titanum]]'' (Titan Arum),'' [[Amorphophallus paeoniifolius]]'' (elephant foot yam), ''[[Helicodiceros muscivorus]]'' (dead horse arum lily) and ''[[Sauromatum venosum]]'' (voodoo lily). Species such as [[Titan Arum]] and the dead horse arum give off a very pungent smell, often resembling a rotten animal. This is to attract flies to pollinate the plant. The heat produced by the plant helps to convey the scent further.
The largest collection of living Araceae is maintained at [[Missouri Botanical Gardens]].<ref>. "The resources which have been built up for aroid research at the Missouri Botanical Garden include one of the largest living collections of aroids and the largest collection of herbarium specimens of neotropical aroids. The living and dried collections include a large percentage of Croat's more than 80,000 personal collections". ({{cite journal| author = Croat, Thomas B|year = 1998| title = History and Current Status of Systematic Research with Araceae| journal = Aroideana| volume = 21}}) </ref> Another large collection of living Araceae can be found at [[Munich Botanical Garden]], thanks to the efforts of the researcher and aroid authority [[Josef Bogner]].
