Croton obliquifolium Visiani (1836a: 223; also treated in Visiani 1836b: 39; 1836c: 70) Locus classicus: —“in AEgypto”. Lectotype (designated here):— EGYPT. s.l., s.d., Acerbi s.n. (PI005428!) (see Fig. 9). Additional specimens examined:— EGYPT. In argine Nili, s.d., Brocchi s.n. (BASSA-BR-112!). Note:—The specimen chosen as type bears a label written and signed by Visiani, and is therefore suitable as a lectotype. This name is now generally considered a synonym of Chrozophora plicata (Vahl) A.Jussieu ex Sprengel (1826: 850) (Euro+Med 2018). Visiani himself evaluated the similarities between these two plants, but he concluded that his new taxon was different from Jussieu’s “because of the genus, the infructescence, the leaves, and the pendulous capsules” (“genere, frutescentia, foliis, capsulis pendulis”).
