Zonal light-coniferous forests are widespread on long-frozen soils in Southern Siberia. Their individuality was first recognised in 1982 by Guinochet, who proposed a new suballiance for them, Pino-Laricenion sibiricae, within the alliance Vaccinio-Piceion. Later, attempts were made to raise the suballiance to the rank of an alliance. However, they failed to publish the name Pino sibiricae-Laricion sibiricae validly according to the International Code of Phytosociological Nomenclature (ICPN). Therefore, the name is validated here after discussing the reasons for rejecting all previous proposals. The validity of the corrected and mutated syntaxon names Rhododendro tomentosi-Laricetalia gmelinii and Rhododendro tomentosi-Laricion gmelinii, which are related to the alliance Pino sibiricae-Laricion sibiricae, is confirmed. Corrections and mutations of two association names are also performed.

The alliance name ‘Pino sibiricae-Laricion sibiricae’ is related to a peculiar regional category of light-coniferous forests occurring on long-frozen soils in the southern part of Siberia and adjacent areas of Northern Mongolia (

In contrast, the name of the new alliance ‘Pino sibiricae-Laricion sibiricae Ermakov’ was not validly published on p. 701 although in the original diagnosis there was only one suitable element designated as the nomenclatural type (“Номенклатурный тип”, in Russian) (Art. 5a), namely the validly published association ‘Carici iljinii-Laricetum sibiricae Ermakov in Ermakov et Alsynbayev 2004’. The invalidity is due to the fact that the same association is also the type of another new alliance name on p. 701, the ‘Ledo-Laricion sibiricae’. Actually, the name ‘Ledo-Laricion sibiricae’ is a typing error for ‘Pino-Laricion sibiricae’ since the ‘Carici iljinii-Laricetum sibiricae’ is indeed the type designated for the ‘Pino-Laricion sibiricae’. Nevertheless, although no type was designated for the name ‘Ledo-Laricion sibiricae’, its diagnosis contains only one suitable element to be designated as the type of the name, the ‘Carici iljinii-Laricetum sibiricae’. Indeed, the names of the two other associations mentioned (‘Ledo-Laricetum sibiricae Zhitlukhina et Alimbekova 1987’ and ‘Bergenio-Pinetum sibiricae Zhitlukhina et Alimbekova 1987’) are not effectively published names (nomina inedita) since in the bibliography of
Regarding the new order proposed to represent the light-coniferous larch (Larix cajanderi) forests occurring on frozen soils in Central Yakutia, the name ‘Ledo palustris-Laricetalia cajanderi’ was validly published in

Following the nomenclatural analysis performed above, we validate here the name Pino sibiricae-Laricion sibiricae Ermakov et Theurillat all. nov. The holotypus of the alliance is the association Carici iljinii-Laricetum sibiricae Ermakov in Ermakov et Alsynbayev 2004 (
The alliance includes the larch and pine-larch (Pinus sibirica, Larix sibirica) forests widespread in the upper part of the forest belt in the continental and ultra-continental climatic sectors of Southern Siberia and adjacent areas of Northern Mongolia, where they occupy north-facing mountain slopes at altitudes of 1400–2000 m a.s.l. At present, the alliance Pino sibiricae-Laricion sibiricae includes nine associations described in Anenkhonov and Chytrý (1997),
