1. Introduction
The genus Allium L. is the largest monocotyledonous genera in the family Amaryllidaceae, with approximately
1078 species naturally distributed throughout the northern hemisphere in worldwide (Friesen et al., 2006; POWO, 2024),
however some of the subgenera may not be monophyletic (Li et al., 2010). The main centers of biodiversity are the Southwest
and Central Asia and the Mediterranean region (Friesen et al., 2006; Li et al., 2010; Chase et al., 2016). Allium cepa L., A.
sativum L., A. fistulosum L., A. ascalonicum L, A. ampeloprasum and A. porrum L. are Allium species with high culinary and
medicinal values. Many Allium species found in the wild in Turkey have ethnobotanical use and among the people, their
leaves and bulbs are consumed as vegetables and spices; their water is drunk, added to cheese, pastry, rice and made into
brine etc. and used for food purposes and earache treatment, appetite stimulant, blood pressure lowering, antiseptic
purposes, strength booster, cold treatment, hemorrhoid treatment, parasite treatment, hair loss, stomach ache, inflamed
wounds, worm reducer, boil treatment, asthma, cough suppressant and flu infection treatment, kidney stone reducer, earache,
rheumatic pain, expectorant, blood pressure lowering, diabetes treatment (Baytop, 1999; Akan et al., 2005, 2008; Balos and
Akan, 2007; Genç, 2010; Koçyiğit, 2010; Ekşi, 2012; Sargın et al., 2013; Akgül et al., 2018; Ekşi Bona, 2018; Yeşil and İnal,

Türkiye an important center of Allium diversity in the Southwest Asia (Koyuncu et al., 2023; Balos et al., 2023; Balos and Sonay, 2024) with 234 species.
In recent years, new species related to Allium, especially sect. Codonoprasum, have been published (Koyuncu et al., 2023; Koçyiğit et al., 2023a; Fırat, 2023;
Koçyiğit et al., 2024; Eker, 2024; Yıldırım et al., 2024; Sonay et al., 2024; Çeçen et al., 2024).
Allium sect. Codonoprasum Reichb., contains 67 taxa (37 of which are endemic) (Koyuncu et al., 2023; Koçyiğit et al., 2023a; Sonay et al., 2024). With
the new species in this study, the number of Allium species in Turkey increased to 232 and the number of sect. Codonoprasum species increased to 68.
The first specimens of the new species described here were collected in August 2023 during the floristic studies carried out in Sultan Kubeys Mountain
(Elazığ, Türkiye) during the scientific field trip, which was the second author's master's thesis study. As a result of the examinations made on the collected
specimens, it was determined that the species was an undescribed species, but due to the lack of specimens for a detailed description, a sufficient number of
plant specimens were collected from the place where the plant was first collected the following year, in August 2024. As a result of detailed morphological studies
on living materials, it was concluded that the plant was a new species and this article was written. The new species presented to your journal under the name
Allium kubeysdaghense was compared in relation to the species A. turcicum and A. turcicum subsp. fusciflorum.
The eastern and south-eastern region of Türkiye region is a less studied region in terms of the Allium genus. In 4 years, new Allium species have been
discovered from Türkiye (Armağan, 2021a, 2021b; Balos et al., 2021; Balos, 2022a, 2022b, 2022c; Balos et al., 2022a; Özdöl et al., 2022; Balos and Geçit, 2023a,
2023b; Balos et al., 2023; Koçyiğit et al., 2023a; Eker, 2023; Fırat, 2024; Koçyiğit et al., 2024; Eker, 2024; Yıldırım et al., 2024). Many new endemic species have
been described in Elazığ (Türkiye) in the last two years (Balos, et al., 2022a; Balos, et al., 2023; Keskin, et al., 2023; Sonay, et al., 2024). This shows that the
region is rich in plant diversity.
2. Materials and Methods
In this study, about 30 specimens were collected in this study from natural locality. For the identification of the collected specimens, the literature on Allium
was reviewed. We consulted Kollmann (1984), Özhatay and Tzanoudakis (2000), and Koyuncu et al., (2023) that deal with the Turkish species. Floras of the
neighbouring regions including Iran, Iraq, Syria and Palestine were also consulted (Boissier 1882; Feinbrun 1948; Wendelbo, 1971, 1985). Additional relevant
publications include Brullo et al., (2013; 2014), Salmeri et al., (2015), Cowley et al., (1993), Özhatay et al., (2018), Bagheri et al., (2020), Ioannidis and Tzanoudakis
(2022), Koçyiğit and Kaya (2020), Trigas and Barega (2020), Armağan (2021a), Pirhan (2022), Balos (2022a, 2022b), Balos et al., (2022a), Özdöl et al., (2022),

Morphological studies were carried out to describe and characterize of this Allium species in all Allium were examined on fresh material using with a
stereo-binocular microscope. The collected specimens are kept in the herbarium of the Harran University Herbarium (HARRAN).
Electron micrographs (Scanning Electron Microscope, SEM) were obtained under a Zeiss EVO 50 SEM at an accelerating voltage of 10 kV, three
seeds were mounted onto aluminium stubs with double adhesive carbon tape and coated with 5 nm thick gold prior to observation. Ornamentation descriptions
(Table 1) on SEM ornamentation images of seeds (Figure 4) were made according to Neshati and Fritsch (2009), Choi and Cota-Sanchez (2010, 2012), Bednorz
et al., (2011), Celep et al., (2012), Lin and Tan (2017), Baasanmunkh et al., (2020; 2021), Khorasani et al., (2020), Ariunzaya et al., (2022, 2023), Shin et al.,
(2022) and Yusupov et al., (2022).

Sonay (Paratype HARRAN).
Etymology: The new species takes its name from Sultan Kubeys, which gave its name to Sultan Kubeys Mountain and where his tomb is located. Sultan
Kubeys Mountain is located between the Kovancilar, Palu and Karakoçan districts, close to the Elazığ-Bingöl border. The new scientific Turkish name suggested
according to the guides of Menemen et al., (2016; 2021) is "Kubeys soğanı", named in honor of Sultan Kubeys.

Distribution and Habitat: Allium kubeysdaghense is a endemic found Elazığ province, eastern Anatolia (Türkiye). It grows on the mountain top, in stony,
steppe areas at 2200–2315 m a.s.l. (Fig. 1). Other plant species grooving nearby are Acantholimon saxifragiform Hausskn. & Sint. ex Bokhari, Achillea millefolium
L. Allium murat-sonayi Balos, Sonay & C.Çeçen, A. pseudoampeloprasum Miscz. ex Grossh., Astragalus acicularis Bunge, A. lagopoides Lam. Helichrysum
arenarium subsp. aucheri (Boiss.) P.H.Davis & Kupicha, Hypericum linarioides Bosse, H. Scabrum L., Jacobaea cilicia (Boiss.) B.Nord., Odontites aucheri Boiss.,
Prometheum sempervivoides (Fisch. ex M.Bieb.) H.Ohba, Tanacetum nitens (Boiss. & Noë) Grierson.
Conservation status: As a result of the Geocat Program Analysis (GeoCAT, 2024), the distribution area of the plant species covers an area of occupancy
(AOO) is 4000 km2, extent of occupancy (EOO) is 0.012 km2. It is estimated that there are less than 200–250 individuals in the only known location. Due to goat
grazing and people's tourist activities, a decrease in the number of the species is expected in the near future. Therefore, according to the IUCN Red List categories
and criteria (https://www.iucnredlist.org/), we assessed its conservation status as "Critically Endangered" (CR) [criterion B2ab [i, ii, iii] (IUCN, 2024).
Allium kubeysdaghense is morphologically similar to A. turcicum and A. turcicum subsp. fusciflorum in general shape and presence of long spathe valves.
But it differs in papyrus-like outer tunic; flexible, purple or green petioles on the upper part of the leaves; leaf sheaths covering up to 2/3 of the total length of the
scape; crescent-shaped leaf cross-section; leaf margins with 3 to 6 scabrous teeth; verrucose leaf surface; non waxy, cream or white bell-shaped perigone;
different structure and shape of inner and outer tepals; reticulate ovary surface, different colour of capsule and ornemantasyon of seed surface (see Fig. 1–4 and
Table 1).

... Codonoprasum, which is the second largest section in Turkey after sect. Allium, includes 69 taxa (39 endemic) (Koyuncu et al. 2023, Sonay et al. 2024a); with the new species described herein this number rises to 70. ...
... Floras of the neighbouring regions including Iran, Iraq, Syria and Palestine were consulted as well (Boissier 1882: 428, Feinbrun 1948, Wendelbo 1971, 1985.

... In addition, very long spathe valves, lax and diffuse umbel, conicalcampanulate perigon, stamens long exserted from perigon and ovary with inconspicuous nectaries indicate that the species belongs to the stamineum group within the section (Brullo et al. 2007, Eker 2024. In our opinion, this species, which has very long spathe valves and a stipitate and a more or less globose ovary, should be placed in a separate group together with species described in recent years such as A. kubeysdaghense (Sonay et al. 2024a), A. turcicum subsp. turcicum (Cowley et al. 1994), A. turcicum subsp. ...

Allium euphraticum Balos, Sonay & U. Çakılcıoğlu (Amaryllidaceae) is described as a new species in sect. Codonoprasum from Elazığ Province, eastern Turkey. It is morphologically similar to A. sultaniae-ferhanii and A. turcicum, but differs from them by, for example, scabrid leaf sheath, backwards curved apex of perigon, creamy and brownish perigon, and presence of teeth at the filament base. Herein we present a detailed description of the species, along with images, an overview of its habitat and ecological characteristics, and a conservation assessment.

Allium decumbens Balos & Sonay is described as a new species from Elazığ Province, Eastern Türkiye. It is an endemic serpentine species that grows on the slopes at an altitude of 2160–2300 m above sea level on the Hazarbaba Mountain in the Sivrice district of Elazığ Province. Based on morphological features, it belongs in Allium subgen. Allium sect. Allium. Allium decumbens is quite different from other species in the section with some of its features. It is morphologically similar to A. murat-sonayii Balos, Sonay & C.Çeçen. However, it clearly differs from A. murat-sonayii by its leaf structure, tunic type, larger bulb, short and decumbent stem, number and shape of leaves, different sheath structure, longer pedicels, umbel structure with radial symmetry, and smooth inner and outer tepals. Herein, the morphology of A. decumbens, a comprehensive description, detailed photographs, habitat and ecological characteristics, and IUCN conservation assessment are provided.

Allium ahmet-tirasii Yıldırım (Amaryllidaceae) is described as a new species from Alanya district in Antalya province, southern Türkiye. Diagnostic characteristics, a full description, and comprehensive illustrations are provided. Based on morphological features, it belongs to the Allium subgen. Polyprason sect. Scorodon. Allium ahmet-tirasii has no closely related species. It slightly resembles A. sivasicum, by the pale brownish-orange inner tunic and greenish-yellow perigone and A. opacum, by perigone size and color also style length. However, it is easily distinguished from both A. sivasicum and A. opacum by many other morphological characters and its habitat. It is characterized by 1–2 equal bulblets; spathe one or sometimes 2-valved, if with 2-valved, valves unilateral; filaments equal or slightly shorter than tepals; style 1.5–2 mm long before fertilization shorter than perigone.

Allium purpureotunicatum Aytaç, Ekşi & Koçyiğit (Amaryllidaceae), a new species of sect. Scorodon, is described and illustrated from Kütahya Province, western Turkey. It is a narrowly distributed geophyte growing on calcareous marl slopes, resembling closely A. sibthorpianum and A. rumelicum. Allium purpureotunicatum differs from those species by its shorter tepals, longer filaments and pistil morphology. It also resembles A. stamineum by having pink flowers, stamens significantly longer than perigon, and a spherical ovary, but differs from it by having coriaceous, distinctly striped and purplish-pink inner tunics as well as fewer flowers. Following IUCN Red List Categories and Criteria, we assessed A. purpureotunicatum as Endangered (EN).

Allium mehmetyaschari Eker sp. nova (Amaryllidaceae) is described as a new species from the Province of Adana, southern Anatolia, Turkey. It is morphologically similar to A. sintenisii and A. erzincanicum in having bearded outer tepals. However, it clearly differs from A. sintenisii by having e.g., smaller bulb, stem and leaves; fewer bulblets; different sheath indumentum; different shape and size of umbel; shorter pedicels; smaller flowers and reproductive organs; different perigone colour; different indumentum structure on outer tepals; smooth inner tepals; and smaller capsule and seeds. It differs from A. erzincanicum mainly in tunic type; leaf structure; densely scabrid sheaths; umbel shape; indumentum shape on outer tepals; smooth inner tepals; ratio of central cup to lateral cups; anther colour; and in having bulblets. Herein, the morphological features, a comprehensive description, habitat and ecological characteristics, detailed images, conservation assessment and micromorphological characteristics of the seeds of A. mehmetyaschari are provided.
