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

"Habitat in America calidiore." RCN: 2967.

Lectotype (Irwin & Barneby in Mem. New York Bot. Gard. 35: 437. 1982): [icon] " Cassia foliolis quinque jugatis " in Plumier in Burman, Pl. Amer.: 68, t. 77. 1756.

Current name: Senna occidentalis (L.) Link ( Fabaceae: Caesalpinioideae).

Note: De Wit (in Webbia 11: 271. 1956) failed to locate relevant van Royen material, and Irwin & Barneby concluded that a Plumier plate was the type. The relationship between the tracings of the Plumier plates (made by Aubriet and published by Burman between 1755 and 1760) and Plumier polynomials cited by Linnaeus has been explored by Gillis & Stearn (in Taxon 23: 185-191. 1974) and Polhill & Stearn (in Taxon 25: 323-325. 1976).
