"Senna artemisioides" is a flowering plant in the family Fabaceae. It is commonly known as Silver Cassia [cite web |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Senna~artemisioides |title="Senna artemisoides" |work = PlantNET Flora of New South Wales|accessdate=2007-12-22 |publisher=Royal Botanic Gardens & Domain Trust, Sydney Australia] or Feathery Cassia [cite web |url=http://cals.arizona.edu/pima/gardening/aridplants/Cassia_artemisioides.html |title="Cassia artemisioides" |accessdate=2007-12-22 |work= |publisher=University of Arizona Pima County Cooperative Extension] - although "cassia" generally refers to the largest-growing Cassiinae. Some of its distinct subspecies also have common names of their own. This plant is endemic to Australia, where it is found in all mainland states and territories, except for Victoria.

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.

Taxonomy and systematics

The species was first described in 1825 by Charles Gaudichaud-Beaupré based on work by Augustin Pyramus de Candolle and placed in "Cassia", but nowadays it has been moved to "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.

A large number of formerly independent species are provisionally considered subspecies of "S. artemisioides":
* ssp. "alicia" Randell
* ssp. "artemisioides"
* ssp. "filifolia" Randell
* ssp. "helmsii" (Symon) Randell – Blunt-leaved Cassia [cite web |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Senna~form+taxon+;qu;helmsii;qu; |title="Senna" form taxon 'helmsii' |accessdate=2007-12-22 |work = PlantNET - Flora of New South Wales |publisher=Royal Botanic Gardens & Domain Trust, Sydney Australia]
* ssp. "oligophylla" (F.Muell.)

* ssp. "quadrifolia" Randell:("Senna quadrifolia" Burm. is a synonym of "Chamaecrista absus")
* ssp. "sturtii" (R.Br.) Randell – Sturt's Cassia [cite web |url=http://plants.usda.gov/java/profile?symbol=CAST47 |title="Cassia sturtii" R.Br. |accessdate=2007-12-22 |work=PLANTS Database |publisher=United States Department of Agriculture]
* ssp. "zygophylla" (Benth.) Randell

Some hybridogenic subspecies have also been named:
* nothosubsp. × "artemisioides" [cite web |url=http://www.anbg.gov.au/cgi-bin/apni?taxon_id=201111 |title="Senna artemisioides" (Gaudich. ex DC.) Randell nothosubsp.

* nothosubsp. × "sturtii" (R.Br.) Randell [cite web |url=http://www.anbg.gov.au/cgi-bin/apni?taxon_id=201111 |title= "Senna artemisioides" nothosubsp. X "sturtii" (R.Br.) Randell |accessdate=2007-12-22 |last= |first= |coauthors= |date= |work= |publisher=Centre for Plant Biodiversity Research, Australian Government, Canberra]

In addition, there are apparently at least 2 undescribed taxa:
* "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.
