Allium urusakiorum (Amaryllidaceae), a new member of the Balkan clade of the section Oreiprason from European Turkey

Abstract

The taxonomy of the Allium saxatile group (sect. Oreiprason) has been studied recently upon morphological and molecular data. New specimens collected from the European part of Turkey near the Istranca Mountains and identified as ‘A. saxatile’ proved to be a new species confirmed by sequences of internal transcribed spacer (ITS) and two plastid DNA regions (rpl32–trnL and trnL–trnF) and supported by morphological characters. Allium urusakiorum, a new species from the A. saxatile group, is described here through living and herbarium specimens. It is the only species of the sect. Oreiprason in the country and seems to be an endemic species of the Turkish flora. Characteristics of the species include morphological description, identification key, molecular dataset, and karyotype (2n = 16).

A contribution to the vascular flora of Bulgaria: new species record and chorological update

“…The identity of the plant species was keyed out through Stoyanov et al (2021), apart from A. urusakiorum being identified via Koçyiğit at al. (2016). The nomenclature follows POWO (2023), except for Isolepis supina, presented as in Kuzmanov & Kozhuharov (1964).…”

“Noah’s Ark” Project: Interim Results and Outlook for Classic Collection Development

“…Geographic isolation was the main cause of previously underestimated speciation: researchers were able to describe new species from Romania, Bulgaria, Russia, Kazakhstan, and China. Later, another type of onion from Uzbekistan [137] and another one from Turkey [138] were described.…”

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.…”
