'''''Senna artemisioides''''' is a [[flowering plant]] in the [[family (biology)|family]] [[Fabaceae]]. It is commonly known as '''Silver Cassia'''<ref>http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Senna~artemisioides</ref> or '''Feathery Cassia'''<ref>http://cals.arizona.edu/pima/gardening/aridplants/Cassia_artemisioides.html</ref> - although "cassia" generally refers to the largest-growing [[Cassiinae]]. Some of its distinct [[subspecies]] also have common names of their own.
This is a shrub that grows up to 3 metres in height. It has pinnate leaves with between 1 and 8 pairs of leaflets. It produces an abundance of yellow flowers in winter and spring which are about 1.5 cm in diameter, followed by 2 to 7 cm long flat green pods which age to dark brown.
The species adapts to a wide range of climatic conditions, although it is susceptible to frost, particularly when young. It prefers dry, well drained sites with full sun. As an [[ornamental plant]], it is propagated readily from seed, which should first be soaked in boiling water.<ref>http://asgap.org.au/s-art.html|title=''Senna artemisoides''</ref>

The species was first described and placed in ''[[Cassia (genus)|Cassia]]'', but nowadays it has been moved to ''[[Senna (genus)|Senna]]''. However, for a long time this plant was erroneously known as ''[[Cassia eremophila]]'' which is a true species of ''Cassia'' called [[Desert Cassia]], described by [[Julius Rudolph Theodor Vogel]]{{wp}}.
A large number of formerly independent species are provisionally considered [[subspecies]] of ''S. artemisioides''{{wp}}:
* ssp. ''alicia'' <small>Randell</small>
* ssp. ''artemisioides''
* ssp. ''filifolia'' <small>Randell</small>
* ssp. ''helmsii'' <small>(Symon) Randell</small> – '''Blunt-leaved Cassia'''
* ssp. ''oligophylla'' <small>(F.Muell.) Randell</small> – '''Blunt-leaved Cassia'''
* ssp. ''petiolaris'' <small>Randell</small> '''Woody Cassia'''
* ssp. ''quadrifolia'' <small>Randell</small>
:(''Senna quadrifolia'' <small>Burm.</small> is a synonym of ''[[Chamaecrista absus]]'')
* ssp. ''sturtii'' <small>(R.Br.) Randell</small> – '''Sturt's Cassia'''
* ssp. ''zygophylla'' <small>(Benth.) Randell</small>
Some [[Hybrid (biology)|hybridogenic]] subspecies have also been named{{wp}}:
* nothosubsp. × ''artemisioides''
* ssp. × ''coriacea'' <small>(Benth.) Randell</small>
* nothosubsp. × ''coriacea'' <small>(Benth.) Randell</small>
:(''Cassia coriacea'' <small>Benth.</small> is a synonym of ''[[Chamaecrista coriacea]]'')
* nothosubsp. × ''sturtii'' <small>(R.Br.) Randell</small>
In addition, there are apparently at least 2 undescribed [[taxa]]{{wp}}:
* ''Senna artemisioides'' "[[James Range]] (P.L.Latz 18528)"
* ''Senna artemisioides'' "[[Kuyunba]] (B.Pitts 113)"
Altogether, ''S. artemisioides'' might be best considered a [[form taxon]] whose [[phylogenetic]] diversity is still largely unresolved{{wp}}.
