Allium negianum (Amaryllidaceae): a new species under subg. Rhizirideum from Uttarakhand Himalaya, India

Abstract

A new species, Allium negianum (Amaryllidaceae), belongs to the genus Allium subg. Rhizirideum, sect. Eduardia is described here from the Uttarakhand Himalayan region of India. This taxon grows in Malari region of Niti valley in Chamoli district and Dharma valley of Pithoragarh district, Uttarakhand, India. It is a narrowly distributed species and morphologically more closer to A. przewalskianum Regel but differentiated by its tunic color of bulb, umbel with lax flowers, peduncle length, perigone colour, size and shape and leaf anatomy. Taxonomic delineation and relationship analysis based on nuclear ribosomal Internal Transcribed Spacers (ITS) region indicated that A. negianum is distinct and related to A. przewalskianum. This study provided a comprehensive description and comparison with A. przewalskianum, an identification key and notes on the distribution of the species.

Allium heterophyllum (Amaryllidaceae), a new species from Henan, China

“…Many new Allium species have been described this year (Armağan 2021;Balos et al 2021;Friesen et al 2021;Pandey et al 2021). During our field investigation in Songxian county in September 2021 (Henan province, China), we discovered a new Allium species (Fig.…”

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.…”

Allium Species in the Balkan Region—Major Metabolites, Antioxidant and Antimicrobial Properties

“…The taxonomic classification of this genus is complex. Earlier classifications, based on inflorescence morphology, traditionally placed Allium in the family Liliaceae, then in the family Amarilidaceae, while recent knowledge which relies on molecular techniques, puts this genus in the following taxonomic position: class Monocotiledones, order Asparagales, family Amarilidaceae [3][4][5][6]. Species of this genus are distributed across the northern hemisphere.…”
