“…The floral charchaters have proven to be valuable in defining relationship within Primulaceae (El-Karemy & Hosni, 1993;Oh et al, 2008;Morozowska et al, 2011;Xu et al, 2016 andLuna et al, 2017). Stamens and pollen morphology have been of interest for over one century few studies on these topics have been done Dickinson, 1989, 1990;Keijzer et al, 1996 andIslam et al, 2008).…”

The circumscription study of Primulaceae is still uncertain and remains controversial. Stamens and pollen grains morphological characters of five species and one variety representing five genera viz., Anagallis, Lysimachia, Coris, Primula and Samolus of Primulaceae in Egypt have been studied using LM and SEM. The specific target of the present study is to evaluate the taxonomic value of the macro and micromorphological characters of stamens and pollen grains in order to distinguish between the studied species. The obtained results showed remarkable variations in anther shape, anther dehiscence, filament attachment and presence of trichomes on the anther filament. Pollen grains are radially symmetrical, isopolar, spheroidal-subprolate to prolate, with amb angulaperturate or fossaperturate and tricolpate or tricolporate. Tectum is microreticulate, reticulate with perforated lumine and clavate exine ornamentation. Out of the studied taxa Coris monspeliensis is distinguished by the presence of prominent margo, reticulate exine ornamentation, minute luminal perforations decreasing towards the colpi, orbicular anther shape, latrorse dehiscence of anthers with short longitudinal slit and presence of glandular diseriate trichomes at the base of the filaments. Clavate exine ornamentation as well as lanceolate anther shape, extrorse dehiscence and short filament can distinguished Samolus valerandi from the remaining studied taxa. An artificial key for the studied species was constructed based on stamens and pollen morphological criteria is provided.

“…Plant species nomenclature follows The Plant List (2013) website. The Androsace specimens were compared with the relevant taxonomic literature (Pax and Knuth 1905, Grossheim 1967, Lamond 1978, Smith and Lowe 1997, Mabberley 2008, Schönswetter and Schneeweiss 2009, Boucher et al 2012, Xu et al 2016, Dentant et al 2018, Jacquemoud and Jordan 2020) and material in the herbaria of ISTE, Selçuk University (KNYA), EGE, Biology Dept of Bingöl University, Nigde Ömer Halisdemir University, Çukurova University (CUEF), ANK and Bolu Abant İzzet Baysal University (AIBU), and some digital herbarium materials were examined from the the E, G and K herbaria. Detailed morphological measurements were performed on the new species and it was compared with the closely related species Androsace albana and A. multiscapa , using a stereo‐binocular microscope.…”

Androsace azizsancarii (Primulaceae) is described and illustrated as a new species from Bayburt Province in northeastern Anatolia, Turkey. Diagnostic morphological characteristics, a full description and a distribution map are provided. The new species is morphologically closest to Androsace albana, A. multiscapa and A. villosa, but it is easily distinguished from these species by indumentum, leaf, flower and seed characters.

Despite the rising interest in biotic interactions in mountain ecosystems, little is known about high-altitude flower-visiting arthropods. In particular, since the research in these environment can be limited or undermined by harsh conditions and logistical difficulties, it is mandatory to develop effective approaches that maximize possibilities to gather high-quality data. Here we compared two different methods, manual sampling and video observations, to investigate the interactions between the high-mountain arthropod community and flowers of Androsace brevis (Primulaceae), a vulnerable endemic alpine species with a short flowering period occurring in early season. We manually sampled flower-visiting arthropods according to the timed-observations method and recorded their activity on video. We assessed differences and effectiveness of the two approaches to estimate flower-visiting arthropod diversity and to identify potential taxa involved in A. brevis pollination. Both methods proved to be effective and comparable in describing the diversity of flower visitors at a high taxonomic level. However, with manual sampling we were able to obtain a fine taxonomic resolution for sampled arthropods and to evaluate which taxa actually carry A. brevis pollen, while video observations were less invasive and allowed us to assess arthropod behavior and to spot rare taxa. By combining the data obtained with these two approaches we could accurately identify flower-visiting arthropods, characterize their behavior, and hypothesize a role of Hymenoptera Apoidea and Diptera Brachycera in A. brevis pollination. Therefore, we propose integrating the two approaches as a powerful instrument to unravel interactions between flowering plants and associated fauna that can provide crucial information for the conservation of vulnerable environments such as high-mountain ecosystems.
