Gypsophila with approximately 150 species represents the fourth largest genus of Caryophyllaceae and the
second genus of tribe Caryophylleae. Iran is the second main center of Gypsophila diversity with 38 species in the world. Considering Gypsophila as one of the most polymorphic genus of the family and almost half of its taxa distributed in Iran a...

Using light and scanning electron microscopy, we studied the pollen morphology of six species (one of which are endemic) of Chinese Pseudostellaria. All species were studied for the first time. Results of this study indicated that pollen grains of Pseudostellaria are spheroidal or spheroidal‐polyhedral in shape and small or medium in size and pantoporate. Each pollen grain has 12–16 round pores. These pores are apart from each other by 5.77–7.73 μm and each has 7–13 granules in the operculum region. These features have important taxonomic significance. In addition, their pollen grains have thin exine with microechinate‐punctate‐perforate surface ornamentation. Pollen features do not support the traditional infrageneric classification of Pseudostellaria into two sections, but support that Pseudostellaria is closely related to other species of the Odontostemma clade. Pollen characteristics can be used to distinguish P. davidii and P. japonica. The pollen characteristics do not support the traditional infrageneric classification into two sections, but support that Pseudostellaria is related to the other member of the Odontostemma clade.
... Pollen grains size (20.7-32 µm), operculum diameter (1.6-6 µm), Distance between pores (2.3-7 µm) and operculum thickness are variable among taxa (Nejad Falatoury et al., 2017). ...
Gypsophila hispida, sect. Hispidae, is reported for the first time from NW Iran. Illustrations, morphological and palynological descriptions and distribution are provided in detail, along with a key for the six taxa of subgen. Hagenia from Iran.
... Pollen morphology of Caryophylleae has been studied extensively (Barkoudah 1962;Chanda 1962;Nowicke 1975;Skvarla and Nowicke 1976;Moore et al. 1977;Al-Eisawi 1989;Taia 1994;Punt and Hoen 1995;Wang et al. 1997;Yildiz 2001;Perveen and Qaiser 2006). Palynological characteristics of Caryophylleae such as shape, size, number of pores and surface ornamentation are proved to have taxonomical importance (Sahreen et al. 2008;Ataşlar et al. 2009;Dong and Guan 2009;Aktaş et al. 2010;Kızılpınar et al. 2010;Nejad Falatoury et al. 2017;Ullah et al. 2018). Many scholars have used palynological characteristics to describe new species as well as distinguish new species from other similar species (Dong et al. 2008;Vural 2008;Kızılpınar et al. 2010;Ma cukanovi c-Joci c et al. 2015;Nejad Falatoury et al. 2015. ...
... Aktaş et al. (2010) discussed the pollen grains of 10 species of Petrorhagia from Turkey and the results revealed that their pollen grains have a tectate exine and had microechinate ornamentation. Nejad Falatoury et al. (2017) studied the pollen grains of 40 species of Gypsophila from Iran and indicated that the pollen grains have a microechinate-microperforate ornamentation. ...
... The other clade contains 20 species, including five species in the study, namely G. cephalotes, G. elegans, G. heteropoda, G. paniculata and G. patrinii. In line with previous results about other species such as G. bicolor (Nejad Falatoury et al. 2017), G. curvifolia (Ataşlar et al. 2009), G. fastigiata and G. repens (Punt and Hoen 1995) in the latter clade, we believe that the pollen characteristics of these two clades are clearly different. The annulus of the former clade contains microechinae, while the annulus of the latter clade pollen grains is smooth or rarely microechinate. ...
Pollen morphology of 43 species two subspecies and three varieties of the genera Acanthophyllum, Dianthus, Gypsophila, Petrorhagia, Psammosilene, Saponaria and Vaccaria, of Caryophylleae was observed and studied in detail using scanning electron microscopy. Among them, 28 species two subspecies and three varieties were reported for the first time. The results show that the number and distribution of pores and surface ornamentation have systematic significance. In addition, pollen morphology contributes to infrageneric evolutionary trends of Dianthus, infrageneric and intergeneric classification of Gypsophila, and reveals the differences between the tribes Caryophylleae and Sileneae.
The Zagros Mountain range is one of the biodiversity centers with the highest percent of endemic species in Iran. There are several peaks with more than 4000 m high in Zagros hosting many rare alpine species. Arenaria is one of the morphological complicated genera with a large number of species and endemism in SW-Asia with an high species concentration in Turkey and Iran. By recollecting the rare and endemic species of Arenaria bulica from locus classicus after 139 years and examining the herbarium specimens, it was found that the two species, A. minutissima and A. semiromica can be considered as its synonyms. A detailed description, original photos, habitat, distribution map, phytogeography, conservation status, seed micromorphology and growth form have been provided and discussed.
Bolanthus including 11 species and all endemic in Turkey. Pollen morphology that belong to the genus Bolanthus were investigated using light microscopy (LM) and scanning electron microscopy (SEM). In this study, all of 11 species in Bolanthus were studied. Pollen of seven species were determined from Turkey and reported for the first time. Pollen shape has two different ornamentation at genus Bolanthus as prolate-spheroidal and oblate-spheroidal. Pollen grains are polipantoporate and isopolar symmetrical. The pollen ornamentation is scabrate-perforate. Pollen diameter, pore diameter, pore numbers, exine thickness, operculum diameter, distance between two pores, spinule numbers, punctum numbers are varying characters between Bolanthus species. The taxonomic separations of the species have been demonstrated with SPSS analysis as dendrogram.
