'''''Rhus''''' is a [[genus]] of approximately 250 species of [[flowering plant]]s in the family [[Anacardiaceae]]. They are commonly called '''sumac''' or '''sumach'''. Some species (including [[Poison ivy]], [[Western Poison-oak|poison-oak]], and [[poison sumac]]), often placed in this genus, are here treated in the genus ''[[Toxicodendron]]'', which differs in highly [[allergen]]ic foliage and grayish-white fruit but is not [[genetics|genetic]]ally distinct. The name derives from the Greek name for sumac, ''rhous''.
[[Image:Rhus_typhina.JPG|thumb|left|A young branch of Staghorn Sumac.]]
The genus is found in subtropical and warm temperate regions throughout the world, with the highest diversity in southern [[Africa]].
They are [[shrub]]s and small [[tree]]s growing to 1-10 m tall. The [[leaf|leaves]] are spirally arranged; they are usually pinnately compound, though some species have trifoliate or simple leaves. The [[flower]]s are in dense panicles or spikes 5-30 cm long, each flower very small, creamy white, greenish or red, with five petals. The [[fruit]] form dense clusters of reddish [[drupe]]s called sumac bobs.
Sumac propagates both by seeds, which are spread by birds and other animals through their [[feces|droppings]], and by new sprouts from rhizomes, forming large [[Clonal colony|clonal colonies]]. <br clear = left>

==Cultivation and uses==
The drupes of the Genus Rhus are harvested, the hairy coating removed and then ground to be used as a [[spice]] (a deep red powder with a sour taste) in some Middle Eastern countries, particularly with salads. In North America, the smooth sumac, ''Rhus glabra'', and the staghorn sumac, ''Rhus typhina'', are sometimes used to make a beverage, termed "sumac-ade" or "Indian lemonade" or "rhus juice". This drink is made by soaking the drupes in cool water, rubbing the active principle off the drupes, then straining the liquid through a cotton cloth and sweetening it. Native Americans also used the leaves and berries of the smooth and staghorn sumacs combined with [[tobacco]] in traditional smoking mixtures.
Species including the fragrant sumac ''Rhus aromatica'', the littleleaf sumac, ''R. microphylla'', the skunkbush sumac, ''R. trilobata'', the smooth sumac, and the staghorn sumac are grown for ornament, either as the wild type or as [[cultivar]]s.
The leaves of certain sumacs yield [[tannin]] (mostly pyrogallol), a substance used in vegetable tanning. [[Leather]] tanned with sumac is flexible, light in weight, and light in color, even bordering on being white.
Dried sumac wood glows under UV lighting (blacklight) {{Fact|date=February 2007}}.
Mowing of sumac is not a good control measure as the wood is springy resulting in jagged, sharp pointed stumps when mowed. The plant will quickly recover with new growth after mowing. See [http://ianrpubs.unl.edu/range/g1319.htm Nebraska Extension Service publication G97-1319] for suggestions as to control.
