摘要

The typification of Euphorbia aphylla and E. piscatoria are discussed. The type of E. aphylla had previously been indicated by Carter in 2002 (repeated in 2022) from material collected by Pierre Marie Auguste Broussonet in Tenerife (Canary Islands, Spain). However, unfortunately the type indication is not effective according to the International Code of Nomenclature for algae, fungi, and plants (ICN, Shenzhen Code, Turland et al. 2018). This paper proposes the effective lectotypification of Euphorbia aphylla and provides data on the specimens collected by Broussonet and used by Willdenow to describe his species. A specimen preserved at BM and collected by Francis Masson in 1776 in Madeira Island (Portugal) is selected as the type of E. piscatoria.
