Senna spectabilis
species of plant
Senna spectabilis is a plant species of the legume family (Fabaceae) in the subfamily Caesalpinioideae native to South and Central America. They are often grown as an ornamental in front yards, parks, gardens, buildings etc. due to their bright yellow flowers that bloom during the summer months. They are also known as golden wonder tree, American cassia, popcorn tree, Cassia excelsa, golden shower tree or Archibald's cassia.
The plant has become an invasive alien species in parts of Africa such as Kenya, Malawi, Tanzania and Uganda, and also in South-India, after it was introduced for resources such as firewood as well as to help combat deteriorating ecosystems affected by deforestation and desertification. Currently, S. spectabilis is overtaking native tree species of forestry ecosystems around the world because of its ability to grow quickly.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Senna spectabilis”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Mar 14, 2026. The linked authority identifier is Q2720974. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
