'''''Sclerocactus''''' ("hard [[cactus]]", from [[Greek language|Greek]]; refers to the hard, dry fruit) is a [[genus]] of [[cactus|cacti]]. It comprises about 15 species, the exact number depending on the authority. These species are very [[xerophytic]]. They are sometimes called 'fishhook cactus' or 'little barrels'. They are ovoid to elongate cylindric, have rigid stems with [[tubercules]] that are ± coalesced into ribs, and are ± covered with spines that come out of the [[aeroles]].<ref name='fna'>Sclerocactus. Flora of North America Online. http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=129764. Accessed 17 December 2007.</ref> Most species have at least one hooked spine at each areole. Less often, species may not have hooks. These plants are found in higher elevation deserts such as on the [[Colorado Plateau]], or in the [[Mohave Desert]] or the [[Great Basin]]. They are well suited to extremes due to lack of rainfall, hot summers and below freezing winters. ''S. parviflorus'' is the most common species; its flowers are usually pink, but are yellow in a few areas (see photo) or, rarely, white or intermediate shades. ''S. polyancistrus'' is the ‘giant’ of the [[genus]]. Some species are quite rare and need considerable further study. ==Cultivation== ===Propagation=== ===Pests and diseases=== ==Species== *''[[Sclerocactus blainei]]'' *''[[Sclerocactus brevispinus]]'' *''[[Sclerocactus cloverae]]'' *''[[Sclerocactus glaucus]]'' *''[[Sclerocactus mesae-verdae]]'' *''[[Sclerocactus nyensis]]'' *''[[Sclerocactus papyracanthus]]'' *''[[Sclerocactus parviflorus]]'' *''[[Sclerocactus polyancistrus]]'' *''[[Sclerocactus pubispinus]]'' *''[[Sclerocactus scheeri]]'' *''[[Sclerocactus sileri]]'' *''[[Sclerocactus spinosior]]'' *''[[Sclerocactus uncinatus]]'' *''[[Sclerocactus wetlandicus]]'' *''[[Sclerocactus whipplei]]'' *''[[Sclerocactus wrightiae]]'' The following genera have been brought into synonymy with ''Sclerocactus'' and this is commonly accepted: *''Coloradoa'' <small>[[Boissev.]] & [[C.Davidson]]</small> *''Toumeya'' <small>[[Nathaniel Lord Britton|Britton]] & [[Joseph Nelson Rose|Rose]]</small> ==Gallery== <gallery perrow=5> Image:Upload.png| photo 1 Image:Upload.png| photo 2 Image:Upload.png| photo 3 </gallery> ==References== <references/>    ==External links== *{{wplink}} {{stub}} __NOTOC__
