Background Camelina sativa (gold-of-pleasure) is a traditional European oilseed crop and emerging biofuel source with high levels of desirable fatty acids. A twentieth century germplasm bottleneck depleted genetic diversity in the crop, leading to recent interest in using wild relatives for crop improvement. However, little is known about seed oil...

Climatic fluctuations in the Pleistocene caused glacial expansion-retraction cycles in Eurasia and other areas of the world. Consequences of these cycles, such as population expansion and subsequent subdivision, have been studied in many taxa at intraspecific population level across much of the Northern Hemisphere. However, the consequences for the...

Formal proposals to amend Recommendation 7A on deposition of type material in institutions of countries of origin, and to add a new Recommendation 51A regarding avoiding potentially inappropriate or unacceptable names of taxa

Smith and Figueiredo, in their recent articles, raised important issues of getting rid of colonial legacy in botanical nomenclature. Some other politically motivated claims and proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN) have also been published or discussed by some other authors. In particular, Smit...

The Helmsman of the Sofiyivka Arboretum. An article in memory of Ivan S. Kosenko (1940–2022), the long-term director of the beautiful Sofiyivka Arboretum in Uman, Ukraine.

New information is provided on the close dates of publication of the two generic names, Osmelia Thwaites (Nov 1858) and Stachycrater Turcz. (Sep-Oct 1858). We propose to conserve the name Osmelia against Stachycrater under Art. 14 of the ICN because we think that decision would best serve nomenclatural stability and would allow continued usage of t...

A formal proposal to conserve the name Aria against Chamaemespilus and Torminalis (all formerly treated in Sorbus s.l., Rosaceae). If this proposal is accepted, the name Aria will be the correct name for a combined genus including Chamaemespilus and Torminalis, but it will not preclude the use of the two latter generic names for those who would pre...

Some years ago, I visited the Kyiv Defense Line of 1941. I have drafted a poem about the Great Battle of Kyiv 1941. Now it is actual, again. Sorry, this poem is in Russian (my second native language, as well as Ukrainian), but I will try to translate it in English later. No surrender. We will stand. Period.

This is from my impressions of Chornobyl (Chernobyl) in 1987. In the village of Kopachi (which I visited with researchers of Dmytro Grodzinsky's team) there was a peculiar and impressive cherry tree in bloom, with several zones clearly visible on the tree: one (protected by the roof of a house) with numerous flowers, another with young leaves but a...

I am publishing here my English translations of two sonnets by Mykola Zerov about the Great City of Kyiv, my native city, which I love so much. I drafted those translations in 2016 but never published them before (just shared with several friends). Now my City is going through its new Ordeal of Fire, but its spirit and soul will live on. Kyiv met m...

A new generic name, Wilketalia S.Y.Kondr. (nom. nov.; Teloschistaceae, lichenized Ascomycota), is published to replace the name Andina Wilk, Pabijan & Lücking (nom. illeg.), which is an illegitimate later homonym of Andina J.A.Jiménez & M.J.Cano (Pottiaceae, Bryophyta) and Andinia (Luer) Luer (Orchidaceae). A new species-rank combination Wilketalia...

A formal proposal to amend Article 41.5 and add an Example clarifying requirements for referring to a basionym or replaced synonym.

These proposals would make attendance at a Nomenclature Section open to a wider audience and therefore more democratic.

The discovery of Ediacaran macrofossils in South Australia in the mid-20th century stimulated systematic studies of Late Precambrian organisms of the Ediacaran Period (635-541 Ma, partly overlapping the Vendian that was widely used before). Most macrofossils of the Ediacaran/Vendian biota have no confirmed analogs among modern organisms, or even am...

The Eurasian species Artemisia vulgaris L. has been reported from the Eastern Cape Province (Stutterheim District) in South Africa since at least half a century. However, examination of relevant herbarium specimens has demonstrated that the South African plant material belongs to a morphologically similar East Asian species, A. verlotiorum. It is i...

Noteworthy records of 11 alien plant species in Kyiv City and Kyiv Region made mainly in 2020 are discussed. In particular, new localities of the following taxa are reported: Amaranthus spinosus, Artemisia tournefortiana, Chenopodium ucrainicum, Celastrus orbiculatus, Datura innoxia, Dysphania ambrosioides, Erechtites hieraciifolius, Mesembryanthem...

Chenopodium rugosum was described by Aellen in 1928, based on a specimen collected in Siberia by Arnell and deposited in the US Herbarium. For a long time, this Aellen's name was forgotten or ignored by the researchers, mainly because of the uncertain identity of that taxon and unavailability of its type. We report here the holotype of C. rugosum r...

A formal proposal to reject the name Chenopodium pallidum (Chenopodiaceae / Amaranthaceae sensu APG). The reasons are explained in the full-text PDF.

The proper type designation of the name Camelina microcarpa Andrz. ex DC. (Brassicaceae) is discussed. This taxon is currently considered to be a wild relative and possible progenitor of the oilseed crop Camelina sativa (L.) Crantz, and thus the proper typification of the name C. microcarpa is important for further germplasm research and improvemen...
