Clementi, Moreno, D’Antraccoli, Marco & Miola, Antonella, 2019, Nomenclatural and taxonomical notes on some taxa described by Roberto de Visiani from Egypt and Sudan, Phytotaxa 399 (1), pp. 49-64 : 51

Heliotropium brocchianum Visiani (1836a: 192 ; also treated in Visiani 1836b: 8; 1836c: 65)

Locus classicus: —“circa Chartum in Sennaar”.

Lectotype (designated here):— SUDAN. Chartoum [Khartoum] in Sennaar, [1824–1826], G.B. Brocchi s.n. (G00147133!) (see Fig. 1 ).

Note:—The label of the specimen we select as type bears, in the handwriting of Brocchi, the following description: “Corolla infundibulif[ormis] limbo 5-fido. Faux pervia, at pilis 5 stellatim dispositi instructa (fauce luteola). Planta prostrata”. This is almost identical to the original description by Brocchi that Visiani (1836a) reports in the protologue. The specimen has been recognised as pertaining to H. ovalifolium Forsskål (1775: 38) .
