The last comprehensive review of Iranian Grasses (Poaceae) dates back to half a century ago in Flora Iranica. Since then, a number of taxa have been described as new species or newly recorded from Iran, and some names have been placed in synonym. This study presents a comprehensive and updated account of all reported Iranian grasses and their classification. The results include 128 genera, 477 species, 64 subspecies and 44 varieties belonging to 37 subtribes, 19 tribes, and seven subfamilies, of which 28 taxa are endemic for Iran. The genera, <em>Elymus,</em> with 7 species and <em>Festuca,</em> with 5 species have the highest number of endemic species. The most diverse genera in Iran are, <em>Bromus</em> (39 spp.), <em>Festuca</em> (27 spp.), <em>Stipa</em> (27 spp.), and <em>Poa</em> (26 spp.). Poeae is the largest tribe, and Pooideae is the largest subfamily in Iran. This paper provides a new name, <em>Festuca neopersica</em> a new combination, <em>Leymus europaeus</em> as well as nomenclatural modifications on the basis of recent taxonomic and molecular investigation of Poaceae taxa related to Iran. The comparison of the species distribution in Iran with that in neighboring countries indicates that Turkey has the most and the Arabian Peninsula the least species in common with Iran, with 305 (64%) and 156 (32%) species, respectively. The species shared with Iran, Pakistan and Saudi Arabia are placed mainly in PACMAD clade, while the species shared with Iran, Turkey and Transcaucasia are mainly placed in PEB clade. Grasslands in Iran are in need of more protection as a result of climatic change and human actions.</span></span></span></p> 2022-11-25T00:00:00+13:00 Copyright (c) 2022 Phytotaxa <p><strong>Vascular flora of Zarrin-Kuh Protected Area in Central Kopet Dagh Mountains, NE Iran: An annotated checklist</strong></p> 2022-11-25T09:09:05+13:00 MOHAMMAD SADEGH AMIRI SHAHRYAR SAEIDI MEHRVARZ FARSHID MEMARIANI MOHAMMAD REZA JOHARCHI <p align="justify"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">Zarrin-Kuh Protected Area (ZPA) is a part of the Khorassan-Kopet Dagh floristic province of the Irano-Turanian region. In this research, we present the first checklist of vascular plants of ZPA along with the life-form spectrum, phytogeography, and conservation status. We conducted field surveys through several random collection efforts and vegetation sampling during 2015–2017. A total of 549 species/infraspecific taxa belonging to 69 families and 318 genera are recorded as native and naturalized plants. The most prominent families are Asteraceae (43 genera/72 species), Poaceae (29/44), Brassicaceae (31/43), Fabaceae (15/43), and Chenopodiaceae (24/41). The richest genera are <em>Astragalus </em>(21 taxa), <em>Euphorbia </em>(10), <em>Acanthophyllum </em>(8), and <em>Allium </em>(8). The therophytes (47.2 %) and hemicryptophytes (25.2%) are dominant in the life-form spectrum. Irano-Turanian elements (347 taxa, 63.2%) are the most common plants; however, the area is inhabited by several Iranian and/or Khorassan-Kopet Dagh endemic, rare and narrow-range plants, among which 17 species are threatened. <em>Astragalus</em> <em>androssovianus</em> Gontsch. is also recorded as new to the flora of Iran. Over-grazing and exploiting valuable plants are the most critical threats to the area. The results support more effective protection practices to ensure the conservation of the unique flora of Central Kopet Dagh. </span></span></span></p> 2022-11-25T00:00:00+13:00 Copyright (c) 2022 Phytotaxa <p><strong>DNA links Andean tepui endemic <em>Helonoma peruviana</em> to <em>Hapalorchis</em> (Orchidaceae, Spiranthinae)</strong></p> 2022-11-25T09:09:07+13:00 GERARDO A.

The systematic position of <em>H. peruviana</em> was assessed by means of a Bayesian inference analysis of plastid (<em>matK-trnK</em>, <em>trnL-trnF</em>) and nuclear (ITS) DNA sequences from 43 genera and 50 species of Spiranthinae, plus suitable outgroups. The analysis recovered <em>H. peruviana</em> as the strongly supported sister of <em>Hapalorchis</em>, being more distantly related to <em>Beloglottis</em>, a genus in which <em>Helonoma</em> has been merged at the sectional level. Despite some differences in perianth morphology, <em>Helonoma</em> and <em>Hapalorchis</em> share both vegetative (densely pubescent roots, decumbent rhizome) and reproductive traits (similar column and pollinarium morphology). <em>Helonoma</em> has a disjunct distribution between the Guiana Shield and the Andean tepui region, and<em> H. peruviana</em> is restricted to the later in Colombia, Ecuador, and Peru.</span></span></span></p> 2022-11-25T00:00:00+13:00 Copyright (c) 2022 Phytotaxa <p><strong>Three new national records from Kon Chu Rang Nature Reserve, Vietnam: <em>Euphorbia bokorensis</em>, <em>Glochidion geoffrayi</em> and <em>Lysimachia nutantiflora</em></strong></p> 2022-11-25T09:09:09+13:00 MAXIM S.

Pistillate flowers are for the first time described for<em> E. bokorensis</em>. <em>Glochidion geoffrayi</em> (Phyllanthaceae) was considered endemic to southern Cambodia, and <em>Lysimachia nutantiflora</em> (Primulaceae) was only known from Guangxi, China. For each species, we provide analytical photographs, information on its habitat, phenology, distribution and studied specimens.</span></span></span></p> 2022-11-25T00:00:00+13:00 Copyright (c) 2022 Phytotaxa <p><strong><em>Leptomischus multiflorus</em> (Argostemmateae: Rubiaceae), a new species from southern Vietnam</strong></p> 2022-11-25T09:09:11+13:00 MAXIM S.
