126. Euphorbia splendens Bojer ex Hook. var. breonii Leandri View in CoL

Notulae Systematicae 12: 159 (1946), nomen, and Cactus (Paris) View in CoL 34: 114 (1952). — Euphorbia milii Des Moul.var. breonii Ursch & Leandri , nom. nud., Mémoires de l’Institut scientifique de Madagascar, série B, Biologie végétale 5: 148, fig. 38 (1954).

REMARK

According to Newton (1994), Euphorbia breonii Nois. is a superfluous renaming of E. milii Des Moul. , but the epithet was misapplied to a new species by Leandri (1946: 159), without validly describing the taxon (see the section “Names invalidly published by Leandri (1946) and Ursch & Leandri (1954) ”). Consequently, Euphorbia splendens Bojer ex Hook. var. breoni and Euphorbia milii Des Moul.var. breonii were invalidly published nomina nuda, excluding the type of their epithet-bringing synonym.

NAMES INVALIDLY PUBLISHED

BY LEANDRI 1946

AND URSCH & LEANDRI 1954

Leandri (1946) introduced in an identification key,

four new varieties of Euphorbia splendens Bojer ex

Hook. without descriptions. In their work on the

Euphorbia from the botanical garden of Tsimbazaza,

Ursch & Leandri (1954) revised this group. They

based new combinations on these three names but,

this time again, did not give any Latin descriptions.

These names are not validly published because they

were not and still have not been “accompanied by

a Latin description or diagnosis or by a reference to

a (…) Latin description or diagnosis” ( McNeill et

al. 2006: Art. 36):

NAMES INVALIDLY PUBLISHED

BY W. RAUH IN SCHILL 1971

In a cytotaxonomic study of the genus Euphorbia L., Schill (1971) mentions two varieties of spiny euphorbias, announcing their description by Rauh in preparation. These species have never been published and their names are therefore two unpublished nomina nuda:

Kingdom	Plantae
Phylum	Tracheophyta
Class	Magnoliopsida
Order	Malpighiales
Family	Euphorbiaceae
Genus	Euphorbia
