Literature. BALAKRISHNAN, N. P. & T. CHAKRABARTY (1993). The genus Paracroton (Euphorbiaceae) in the Indian subcontinent. Kew Bull. 48: 715 - 726, ff. 1 - 3.

Notes. The generic name Fahrenheitia Reichb.f. & Zoll. ex Müll.Arg. used in most recent floras of Indian region, is invalid as it was published as nomen provisorum by Reichb.f. & Zoll. in 1857. The next published name for the genus, Paracroton Miq. (1859) is to be used as discussed by Balakrishnan & Chakrabarty (l. c.).
