suffruticosa (J.Koenig ex Roth) Chatterjee Psilorhegma suffruticosa (J.Koenig ex Roth) Britton Senna surattensis, also called glossy shower, scrambled egg tree, glossy shower, golden Senna, glaucous Cassia, sunshine tree and bushy Cassia, is a plant species of the legume family (Fabaceae) in the subfamily Caesalpinioideae that is native to southeast Asia, and possibly northern and eastern Australia.

[5][6][7] S. surattensis is named after Surat district, situated near Bombay, India.

Sepals are rough, elliptic, 3-8 mm long, glabrous or sparsely hairy, and green.

Petals are oblong-elliptic, 10-24 (-30) mm long, hairless or just mildly hairy, yellow, with a distinct venation.

Antecedently, it was thought to be native to coastal north Australia and Malesia, but Symon (1966) stated that it was likely introduced there.

Agricultural Research Service (2014) lists the plant as native to Laos, Myanmar, the Philippines, Thailand, and Vietnam.

[8] The species is known to occur in several tropical and subtropical regions including Southeast Asia, Africa, and the West Indies, where it has escaped into the wild, thereby naturalizing in these places.

It can easily be toppled by heavy winds, therefore it needs many years to become established in ground.

It also may have been cultivated in Trinidad by 1870 and it was introduced as an ornamental plant in Puerto Rico just after 1826.

It is classified as an invasive species in various Asian and Pacific countries such as Singapore, Taiwan, French Polynesia, and Micronesia, including Hawaii.

Eurema blanda only eats the young leaves, and Oecophylla smaragdina will frequently build nests on the plant.
