It resembles G. halophilus by its secund inflorescence, obovoid fruit, and winged seed, and is related to G. anatolicus based on its leaf and flower features. Also it is compared to G. illyricus because of having some leaf, flower features, and winged seed characteristics. Its distribution, habitat and ecology, etymology, conservation status and diagnostic morphological, and taxonomic features with familiar species are discussed in this paper. Additionally, pollen and seed micromorphological characteristics of G. hamzaoglui, G. halophilus, and G. anatolicus are examined and compared using LM and SEM analyses. IUCN conservation status of G. hamzaoglui is suggested as Endangered (EN) category.

The aim is to identify the pollen morphological characteristics of 23 Ferula species. The pollen is radially symmetrical, isopolar and tricolporate in all examined species. Pollen grains are prolate and perprolate with the polar axis ranging from 22.28 to 40.47 µm and the equatorial axis from 13.70 to 18.73 µm. Their polar shapes are triangular, triangular to subtriangular and circular to subcircular. Several types of exine ornamentations have been observed on pollen through the use of scanning electron microscopy. The dendrogram constructed by using Average Linkage of the examined data revealed two main groups. It was determined that some pollen characteristics are more useful for classification than others. In particular, P, E, the ratio of P/E (pollen shape) and ornamentation in the polar and equatorial views are the most valuable variables for discrimination the Ferula species.

Sa g ıro g lu & H.Duman, sp. nov. from northeast Anatolia in Turkey (A8: Artvin & Erzurum) is described and illustrated. It is closely related to F. coskunii H.Duman & M.Sa g ıro g lu, from which it differs mainly in its habit, basal leaves, umbel, and mericarp features. Diagnostic morphological characters are discussed. Notes are also presented on its ecology and conservation status, together with scanning electron micrographs of the surface of the mericarps and of a somatic metaphase plate showing the chromosome number.

The antioxidant activity was investigated by determining the percentage of 2.2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity of ethanolic extracts at a concentration of 1 mg/mL. The highest antioxidant activity was found in the corm part of C. flavus subsp. flavus, whereas, the lowest value was detected in the aerial part of C. danfordiae subsp. danfordiae. For the total phenolic content, the highest and the lowest values were observed in the corm of C. olivieri subsp. istanbulensis at 390 mg GAE/100 g and in the aerial part of C. danfordiae subsp. danfordiae at 24.4 mg GAE/100 g, respectively.

Questions: What is the ethnobotanical usage culture of geophytes in Sakarya province? Studied species: Geophytes. Study site and dates: Sakarya, Turkey; 2017 to 2020. Methods: Information in the local community was obtained through face to face or collective interviews. In addition, cultural importance index (CII) and the informant consensus factor (ICF) values were calculated. Results: In this study, the knowledge of the local public about 115 geophytes (107 natural and eight cultivated) belonging to 26 families was revealed. The most common families are Asparagaceae (23 taxa), Iridaceae (21 taxa) and Amaryllidaceae (14 taxa). The most common genera are Crocus (12 taxa), Orchis (7 taxa) and Allium (6 taxa). Out of a total of 115 taxa, 226 uses are reported, including 128 folk remedies, 47 ornamental plants, 48 food and three the other uses. The most widely used plant according to cultural importance index is Leucojum aestivum (Gölsoğanı, CII: 2.57). Conclusion: Our interviews revealed that the geophytes in the study area are still widely used by people in their daily lives for medicinal, food and floricultural purposes. In addition, the ethnobotanical uses of Crocus speciosus subsp. sakariensis, Crocus keltepensis, Fritillaria bithynica and Muscari pamiryigidii are reported for the first time in Turkey.

Koch was firstly collected from Tekirdağ province in 1969. The morphological description of the species in “Flora of Turkey and the East Aegean Islands” was written based on these specimens. The species has not been collected for along time untilday. This species was re-collected by us during a flora study in 2014 at Malkara district, Karaiğdemir Dam road in Tekirdağ. The name of this species was mispelled. This situation has been corrected here. Its correct use is Opopanax chironius. Also, in this study, expanded description of the species, pictures, disdictive morphological characters from other species, ecology, fruit photographs and ethnobotanical usage were given.

Achene characterization is a very important criterion used in the distinction of Tripleurospermum species as well as those in Asteraceae family. Important taxonomic characteristics are achene size, shape, corona structure, number of ribs, thickness and width of lateral and adaxial ribs, and presence or absence of slime cells

Gladiolus izzet-baysalii is not morphologically close to any of the species of Gladiolus in Turkey. Although it has some similarities with G. illyricus and G. hamzaoglui in terms of habitus, G. izzet-baysalii differs significantly in tunic structure, number of leaves, inflorescence, perianth, anther, style, capsule and seed features. In this study, the diagnostic morphological features, distribution, conservation status, habitat and ecological characteristics of the new species are discussed. Micromorphological characteristics of G. izzet-baysalii, G. illyricus and G. hamzaoglui seeds are also examined and compared using stereomicroscope and SEM analyses.
