Seed micro‐morphology and its systematic significance in Gypsophila (Caryophyllaceae) and allied genera

Abstract

In order to examine the systematic application of seed-coat micro-morphology in Gypsophila and allied genera, seed surfaces of 30 species and two varieties representing four genera of tribe Caryophylleae were examined with scanning electron microscope. The seeds of examined species range between 0.5Á2.1 mm in length and 0.3Á2.4 mm in diameter. The exomorphology of the seed coat shows two distinctive cell patterns. The epidermis is constructed either of elongated polygonal or of broad polygonal cells. The elongated type is the most common among the studied species, but the variation in alignment of testa cells, their size and shape as well as the density of protuberances may provide further information and useful diagnostic characters at generic and specific rank. The testa cells in Gypsophila and Saponaria are shallowly undulate, deeply undulate, lobed and armed at anticlinal walls. Deeply undulate anticlinal walls were observed in both Gypsophila and Ankyropetalum and a few species of Saponaria. Non-or indistinctly grooved anticlinal walls is the more common type in Allochrusa. Seed-coat characters support the separation of Gypsophila and Saponaria to some extent but disagree with recognition of Ankyropetalum as a genus separate from Gypsophila.

Seed micromorphology and its taxonomic evidence in subfamily Alsinoideae (Caryophyllaceae)

“…The available literature suggests that seed micromorphological characters provide an important valuable feature for delimitation of different species and genera of the family Caryophyllaceae (Fawzi, Fawzy, & Mohamed, ; Hong, Han, & Kim, ; Kanwal et al, ; Minuto et al, ; Mostafavi et al, ). Different seed micromorphological characteristics, that is, seed color, seed shape, hilum, anticlinal wall, epidermal cell, cell surface, margins of cell, length, and width were studied to be important in distinguishing plant entities at different taxonomic level (Amini et al, ; Kanwal et al, ; Minuto et al, ; Mitra Arman, ).…”

“…The seed morphological characters here identified and measured are helpful and can provide enough differential characters at the interspecific level (Crow, 1979;Wofford, 1981;Yildiz, 2002). (Amini et al, 2011;Kanwal et al, 2012;Minuto et al, 2006;Mitra Arman, 2013).…”

“…Seed micromorphological features are very useful for identification and taxonomic delimitation of various plant groups (Arabi, Ghahremaninejad, Rabeler, Heubl, & Zarre, 2017), and more precisely in different genera of family Caryophyllaceae (Amini, Zarre, & Assadi, 2011;Hoseini, Ghahremaninejad, Assadi, & Edalatiyan, 2017;Kanwal, Abid, & Qaiser, 2012;Sadeghian, Zarre, & Heubl, 2014). Seed morphology has been shown to be specifically valuable in delineation of narrowly allied genera.…”

Seed micromorphology of Acanthophyllum C.A.Mey. (Caryophyllaceae) Genus inTurkey

“…Species in our research was unwinged and were not have projections. Amini and et al (2011) investigated seed morphology of 22 species of Gypsophila L., five species of Saponaria L., two species of Allochrusa Bunge ex Boiss. and one species of Ankyropetalum Fenzl were examined by scanning electron microscope.…”
