Allium pallasii and A. caricifolium—Surprisingly Diverse Old Steppe Species, Showing a Clear Geographical Barrier in the Area of Lake Zaysan

Abstract

Polymorph Allium pallasii s.l. from monotypic A. sect. Pallasia was studied using a wide spectrum of methods and divided into two clearly morphologically, geographically, cytologically and genetically isolated species: A. pallasii s. str.—North-East Kazakhstan, Western Siberia, and the Altai Mountains; A. caricifolium—Kyrgyzstan, Northwest China, South-East Kazakhstan until Zaysan Lake in the east. Despite serious genetic differences, both species are sisters and are related to species of the A. sect. Codonoprasum (Subg. Allium). Allium caricifolium differs from A. pallasii s. str. by taller stems, dense inflorescence, and with filaments longer than perianth. The possible phylogenetic reasons for the separation of these species are discussed. A nomenclature analysis of synonyms was carried out.

Analysis of the representation of species of the genus Allium L. flora of Aral-Balkhash region in the Herbarium (AA)

“…В процессе изучения были использованы данные следующих литературных источников: «Флора Казахстана» [4], «Иллюстрированный определитель растений Казахстана» [8], «Определитель растений Средней Азии» [9], Государственный кадастр растений Жамбылской [10] и Кызылординской областей [11], Красная книга Казахстана [12]. Кроме того, были использованы данные некоторых статей, монографий и диссертаций по флоре рассматриваемого региона.…”

Flower morphology of Allium (Amaryllidaceae) and its systematic significance

“…Allium is characterized by the presence of bulbs enclosed in membranous tunics, flowers with six free, or almost free, tepals, and often a subgynobasic style ( Fritsch and Friesen, 2002 ; Friesen et al., 2006 ; Choi et al., 2011 ; Choi and Oh, 2011 ). Recently, a number of Allium species have been described as new to science based on their morphology (e.g., Armağan, 2021 ; Khan et al., 2021 ), or mixed morphological, including molecular and karyological properties (e.g., Koçyiğit et al., 2016 ; Choi et al., 2019 ; Xie et al., 2020c ; Friesen et al., 2020 , 2022 ; Jang et al., 2021 ; Pandey et al., 2021 ; Bartolucci et al., 2022 ; Khan et al., 2022 ). In general, the major morphological traits used to assess Allium taxonomy include rhizome and bulb tunics, stamens, tepals, and filaments.…”

MATO: An updated tool for capturing and analyzing cytotaxonomic and morphological data

“…4,7 Light microscopy, the conventional and convenient method, determines chromosome count and ploidy. [8][9][10][11] When investigating plant morphological characteristics, different traits require distinct approaches for identification. Discontinuous traits, such as flower cardinal number and chromosome count, can be observed and manually counted.…”
