Note. – The type of Iresine edmonstonei that was collected by Edmonston might have been from a plant introduced by early settlers or the specimen was mislabeled to originate from Galapagos (Eliasson, 1985). The folder of I. elatior in the Willdenow herbarium (B) contains four sheets, only two of which have labels. Sheet 0 4 is the only one with a label saying “ Iresine – spec. nova”. The fact that the folder itself contains on its inside three more labels, out of the hand of Bonpland as well as Schlechtendahl (H.W. Lack, pers. comm.) is a further indication of a different origin of the sheets but also that these three labels cold not unambiguously be assigned to any of the sheets. A lectotypification is therefore warranted. The geographic origin of the specimens is unknown. The type specimen of I. laxissima is from a hermaphroditic plant and has only bisexual flowers.
The name “ Rosea poeppigiana Klotzsch ” is not validly published but was listed by Seubert (1875) as a synonym of I. elatior Rich. ex Willd. There is a specimen in B (E.F. Poeppig s.n., B 10 0 242399, from Brazil, Pará) annotated with the name “ Rosea poeppigiana Kl. ”. The handwriting is clearly by J.F. Klotzsch (R. Vogt, pers. comm.). Seubert cited this name as it was often practised at the time.
Taxonomic status: Species limits not yet studied in detail (B).
