Cassia senna Linnaeus, Species Plantarum 1: 377. 1753.

"Habitat in Aegypto." RCN: 2971.

Lectotype (Valenti in Webbia 26: 62. 1971): [icon] " Senna Alexandrina sive foliis acutis" in Morison, Pl. Hist. Univ. 2: 201, s. 2, t. 24, f. 1. 1680.

Current name: Senna alexandrina Mill. ( Fabaceae: Caesalpinioideae).

Note: Brenan (in Milne-Redhead & Polhill, Fl. Trop. E. Africa, Leguminosae 2: 65. 1967) stated that the type was uncertain but that Morison’s plant agreed with usage of the name. Valenti was the first to make a formal type choice.
