Anatomy and micromorphology of the endemic Gypsophila osmangaziensis (Caryophyllaceae) and taxonomic contributions for the genus Gypsophila

Abstract

Gypsophila osmangaziensis, an endemic species from Eskişehir (Turkey) is here studied from the anatomical and micromorphological points of view for the first time. Root, stem and leaf cross-sections as well as seed, leaf and pollen grains surfaces are investigated. Root shows perennial characteristics. Pericycle layer of the stem is composed of sclerenchymatic cells that have 15–17 very thick, layered cell walls. Leaf mesophyll is isobilateral and partly carries druse crystals. Seed surface has an obtuse tubercle. Pollen shape is oblate spheroidal.

Anatomical, palynological, morphological, karyological, and ecological investigations on Gypsophila davisii

“…Anatomy of root, stem and leaves well fit with the descriptions of Metcalfe & Chalk (1957), Barkoudah (1962) and Ataşlar & Ocak (2017) perfoliata L. was x=17, 18, 24, and 34 (Rice et al 2014).…”

“…Anatomy of root, stem and leaves well fit with the descriptions of Metcalfe & Chalk (1957), Barkoudah (1962) and Ataşlar & Ocak (2017 , 18, 24, and 34 (Rice et al 2014). It could be suggested that there is polyploidy in some species of Gypsophila based on these amounts.…”

“…The pollens of Gypsophila taxa are spheroid and polyporate, and generally have granulate-microechinatemicroperforate ornamentations (Ataşlar et al, 2009). Members of Gypsophila contains excess amount of calcium oxalate crystals in the structure of their roots and stems (Ataşlar and Ocak, 2017). Although diploid number of the chromosomes (2n=34) is a typical representative of this genus, the differences at a ploidy level has been found between the Gypsophila species (Vettori et al, 2015).…”
