As part of a study of Iberian and Balearic Araceae, two Linnaean names, Arum proboscideum L. and A. mus- civorum L. f., are lecto- and neotypified, respectively.

In the indigenous Araceae of the Iberian worked before Boccone, but his publication only Peninsula and Balearic Islands there are some Linnaean appeared posthumously (see also Savi, 1816).

Cafferty (in litt.) comments, there is not included in the recent monographs of Arisarum no herbarium material available for typification, only the (Boyce, 1990) and Helicodiceros (Boyce, 1994), and Boccone or Barrelier illustrations.
