The identity of Polanisia angulata DC. is discussed and the Linnaean names Cleome fruticosa L. and C. monophylla L. (Cleomaceae) are typified. The typifications of the two Linnaean names are based on an assessment of Linnaeus' original materials and the literature cited in the protologue. Examination of type specimens and protologues of the names Cleome chelidonii var. pallae C.S. Reddy & V.S. Raju, Corynandra elegans Chandore, U.S. Yadav & S.R. Yadav, C. pulchella Schrad. ex Spreng. and Polanisia angulata showed that all are conspecific. Thus, a new combination Corynandra angulata (DC.) R.Kr. Singh, Arigela & C.S. Reddy is proposed for the first available name Polanisia angulata. Lectotypes are also designated here for Polanisia burtporensis Munro and the Linnaeus filius' names Cleome chelidonii L.f., C. felina L.f. and C. tenella L.f.
