Note. – No lectotypification of Iresine latifolia was made by Pedersen (1997), who also cited a wrong collector’s number (Galeotti 520) for the type. The two Galeotti specimens mentioned in the protologue are numbers 420 and 423. We have selected Galeotti 423, the sheet with barcode 0 0 0 0 0 6952501, which has the more complete label; the isolectotype could be a duplicate for which a simpler label was just written by hand. Standley (1916) erroneously made a new combination using Achyranthes calea Ibáñez as basionym, assuming that “ Iresine latifolia D. Dietr. ” was already available as a validly published name. However, as pointed out by Pedersen (1997) the name Iresine latifolia appears nowhere on p. 870 in Dietrich’s Synopsis plantarum (vol. 1, 1839), although this is cited by Moquin-Tandon (1849: 351). On the other hand, Moquin-Tandon mentiones two pages earlier (p. 349) “ Iresine latifolia = Alternanthera pulverulenta ”, which apparently is an error because Alternanthera latifolia is the next entry on p. 351 of Moquin’s treatment. No specimen of I. latifolia var. velutina could be localized at B. The existence of duplicates that could serve as lectotypes cannot be excluded as Endlich specimens are in various herbaria such as G, L and MO (electronic search so far not successful).
Taxonomic status: Probably a natural entity (monophylum) as currently defined (A).
