Likewise, over the last two decades, the number of known species in Iran has tripled with the discovery of 16 additional species. Despite these noteworthy recent findings, there is a lack of an updated taxonomic revision that encompasses all these newcomers. This revision of the genus in Iran is based on comprehensive morphological examinations conducted on fresh plant material collected in the field, cultivated plants, herbarium specimens, and an extensive literature review. Presently, 24 species are recognized in Iran. They are classified into two sections: <jats:italic>Crocus</jats:italic> and <jats:italic>Nudiscapus</jats:italic>. Notably, 18 species (75%) are endemic to Iran, with 14 among them being steno‐endemics, the five remaining species are subendemic elements whose distribution is limited to Iran and the adjacent countries. An identification key to all 24 recognized species is presented, accompanied by illustrations, detailed descriptions, distribution maps and information on the conservation status of each species. According to the IUCN criteria, the conservation status of all species, excluding <jats:italic>C. caspius</jats:italic>, <jats:italic>C. damascenus,</jats:italic> <jats:italic>C. haussknechtii</jats:italic> and <jats:italic>C. michelsonii</jats:italic> is at an alarming level.

The annual mean temperature, mean temperature of the wettest quarter and annual precipitations were the most critical parameters that chiefly influence the distribution of <i>D. melanoxylon</i>. The ensemble model rendered high accuracy with AUC = 0.93, TSS = 0.74 and Kappa = 0.71. Past projections of <i>D. melanoxylon</i> indicated a widespread distribution during LGM and MH suggesting its adaptability to semi-dry as well as warm and humid climate, respectively. Presence of fossil pollen evidence of <i>D. melanoxylon</i> in the suitable habitats derived through past projections in this study complements the model results and marks occurrences of the species during LGM and MH. By 2050s and 2070s (RCP 8.5), there would be a decline in the distribution by only 0.4% (13 622 km²) and 0.2% (6842 km²) of the extremely suitable habitats, respectively. The main factor leading to reduced habitat suitability is the anticipated rise in temperature and variations in seasonal precipitation patterns. Our findings, help in identifying the parts of the country which would be severely affected by future climate change scenarios and plan conservation strategies for this commercially important species to facilitate its growth in suitable habitats which are likely to sustain under future climatic conditions.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":"23 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140172325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We collected phenotypic data from herbarium specimens and garden‐grown plants of <jats:italic>S. autumnalis</jats:italic>, representing several habitats throughout Scandinavia and Iceland, and subjected progenies from controlled crosses within a subset of the common garden material to different temperature regimes to assess patterns of phenotypic plasticity. Our results strongly suggest that colour and indumentum of involucral bracts, as well as the size of capitula (measured by ligule length), are environmentally plastic and much affected by temperature. Reduced temperature resulted in significantly larger capitula, with both thicker and darker involucre indumentum. Since dark colouration, dense indumentum and large floral structures have been shown to facilitate heat retention and insect visitation in other plant species growing in cold climate, we hypothesize that plants of <jats:italic>S. autumnalis</jats:italic> benefit from possessing these features under cool conditions, and that much of the geographical variation in capitulum characters reflects adaptive phenotypic plasticity rather than ecotypic divergence.
