Allium alexeianum

Discussion of the taxon / Таксоны / Forum

В IPNI и TROPICOS есть ещё и Allium hissaricum Vved. Вот только это не синоним Allium alexeianum var. hissaricum Lipsky...

I never saw Allium hissaricum, but it certainly isn't A. alexeianum var. hissaricum. Differences between Allium nevskianum and A. alexeianum observed by me are: Allium nevskianum - has 2 leaves, is growing on stone-slides, stem push flowerhead well over leaves, increases by bulb splitting even in wild (largest clump seen consisted from 18 bulbs), bulbs lie in ground deeply. Good grower in cultivation even in open garden. Allium alexeianum - has only 1 leaf, is growing on "melkozemi" (flat, hard clay), flowerhead sitting on very short stem, never increases by splitting of bulb even in cultivation. Difficult to cultivate, here succeed only in greenhouse under cover. There are smaller morphological differences, too. Seeing both in nature, no doubt that they are different. According Fritsch, leaf number is not important as it varie in both species

By the way - all former pictures on Plantarium labelled as Allium alexeianum, really are A. nevskianum. In 1982, when I collected the first bulbs from this complex in Varzob gorge, initially I identified them as A. alexeainum, too. I was very inexperienced and only started my collections, but later I soon discovered mistake. There is excellent publication about CA Allium taxonomy in which you will found following key: 40. Flowers broadly funnel-shaped, tepals lanceolate, patent, dirty red or greenish-brown, in the dry state prickly by a thick stiff median vein (77) Allium alexeianum 40* Flowers narrower funnel-shaped, tepals narrowly lanceolate, somewhat recurved, pink to purplish, in the dry state soft becoming only crumbled (79) Allium nevskianum See: A Preliminary Review of Allium subg. Melanocrommyum in Central Asia by Reinhard M. Fritsch. Leibniz-Institut für Pflanzengenetik und Kulturpflanzenforschung Gatersleben (IPK), 2016 Unfortunately it was not published in printed form (lacking of financing) but only on internet. Another paper about Alliums of Iran is in printed form, too.

Something more from Fritsch, 2016: By the way - Allium nevskianum is crossable with A. sarawschanicum and there is reported hybrid with stipitatum by E. Dambrauskas, Lithuania

Allium hissaricum belongs to completely different group of Allium species - sect. Regeloprason and closest relatives are A.A. darwasicum, lipskyanum, sochense. A. nevskianum and alexeianum belongs to sect. Kaloprason

Is "Allium nevskianum Vved." and "Allium nevskianum Wendelbo" really different combinations or just differently recorded "Allium nevskianum Vved. ex Wendelbo"?

As I see, we have to separate Allium alexeianum and Allium nevskianum. Such point of view is accepted in POWO http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:527560-1 http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:528483-1 WFO http://www.worldfloraonline.org/taxon/wfo-0000755581 http://www.worldfloraonline.org/taxon/wfo-0000756822 GBIF https://www.gbif.org/species/2857024 https://www.gbif.org/species/2855769 Any objections?

Как я понимаю, возражения отсутствуют.

Переименовал "Allium nevskianum Wendelbo" в "Allium nevskianum Vved. ex Wendelbo" и сделал его отдельным видом. Перенёс все ранее загруженные фото от Allium alexeianum к Allium nevskianum, за исключением

А на заглавном фото растения с 2 листьями, что противоречит п. 2 настоящего обсуждения.

А, ну тогда ладно.

Снимок, который сейчас выбран главным, Янис отнёс к A. nevskianum: https://forum.plantarium.ru/viewtopic.php?pid=431038#p431038

Перенёс к A. nevskianum оба фото, где это название упомянуто в имени файла.

Да, это разные комбинации, причём "Allium nevskianum Vved." (1971) (обнародованная во 2-м томе ОРСА), похоже, ещё и незаконная. Запись "Allium nevskianum Vved. ex Wendelbo" (1969) верна и приоритетна.

Добавлю "nom. illeg." к "Allium nevskianum Vved."?

Да.

Сделал.
