In the course of preparing our unpublished synopsis of the New World Cleomaceae, we found it desirable to make a number of changes in classification. Consequently, the genus Corynandra Schrad. ex Spreng., an earlier name for Arivela Raf., is re-established with Corynandra chelidonii (L. f.) Cochrane & Iltis [≡ Cleome chelidonii L. f.], C. felina (L. f.) Cochrane & Iltis [≡ Cleome felina L. f.], C. flava (Banks ex DC.) Cochrane & Iltis [≡ Cleome flava Banks ex DC.], and C. viscosa (L.) Cochrane & Iltis [≡ Cleome viscosa L.]. Also, one infraspecific combination is made, namely Corynandra viscosa subsp. nagarjunakondensis (Sundararagh.) Cochrane [≡ Cleome viscosa var. nagarjunakondensis Sundararagh.], and lectotypes are designated herein for Polanisia leschenaultii DC. and P. viscosa DC. var. grandiflora Benth.
