“…They investigated morphological features and phylogenetic relationship using molecular ITS markers of some Alnus taxa and reported that these sub-species had very similar features. Meanwhile, Hosseinzadeh-Colagar et al (2016) analyzed of trnH-psbA sequence data of different Alnus taxa and suggested that the recognized A. glutinosa subspecies were distributed among the other species of the genus.…”

“…For example, Shayanmehr et al (2014) evaluated morphological characteristics of different Alnus taxa in Iran. The molecular phylogeny of the genus according to two DNA barcode markers was not congruent with the last morphological classifications (Hosseinzadeh-Colagar et al, 2016), and Gholamiterojeni et al (2019) performed a revision of this genus in the country using molecular ITS markers and morphological characters and recognized some new taxa. But we could not find any study related to seed micromorphology of Alnus in Iran.…”

Alnus Mill. is a problematic genus of Betulaceae, and there are several intrageneric classifications for the genus. Alnus species are widely distributed in the Hyrcanian forest of Iran, and different species with some intraspecific taxonomic ranks including subspecies and varieties have been reported from this country. We evaluate seed micromorphology characteristics of ten taxa using scanning electron microscopy and light microscopy in the current study. The data were analyzed using SPSS and MVSP software. Results revealed that qualitative characteristics such as seed shape, surface sculpturing pattern, presence of indumentum, and its type vary among the studied taxa and have diagnostic value. However, seed color was nearly stable among the taxa. Besides, quantitative variables highly differed among the taxa. In the UPGMA tree, Alnus taxa were clustered into three groups, and these groups were supported by PCA and PCO plots. According to the PCA bi-plot, some taxa were characterized by the particular characteristic(s) that was useful for their identification. In some cases taxa clustering was similar to those of previous phylogenetic and morphological studies. Our findings revealed that seed morphology characteristics are a valuable taxonomical tool in identifying most Alnus taxa, except for A. glutinosa subspecies, which have similar seed morphology features in common.

“…Ploidy level diversity in Alnus has been poorly investigated. Published chromosome data were summarized by Fedorov (1974), but the most recent papers dealing with phylogenetic relationships in Alnus (Navarro & al., 2003;Chen & Li, 2004;Colagar & al., 2016) or even Betulaceae (Chen & al., 1999;Li & al., 2005) do not take ploidy levels or chromosome counts into account. In Alnus, closely related yet morphologically well-defined taxa of different ploidy levels are treated as separate species or as subspecies in cases where morphological differentiation is not substantial (e.g., A. incana subsp.…”

In the present study, we investigate the variation of European representatives of Alnus subg. Alnus, i.e., Alnus glutinosa and A. incana, in Europe and partly North Africa. Four distinct Alnus taxa were recognized using a multidisciplinary approach based on multivariate morphometrics, karyology, flow cytometry and nuclear microsatellite analyses. Besides the long-recognized diploid taxa (2n = 2x = 28) A. glutinosa and A. incana, we revealed the presence of morphologically, cytologically and genetically noticeably delimited tetraploid populations (2n = 4x = 56), which we consider new species. These form two geographically well-delimited clusters located in the Iberian Peninsula and the adjacent part of North Africa, designated here as Alnus lusi tanica, and in the Dinaric Alps extending south-easterly to Greece, denominated here as Alnus rohlenae. Detailed information concerning their diagnosis and geographical distribution is presented, and photographs of type specimens are provided.
