“…Several studies have been carried out on the seed morphological characters and their taxonomic significance. Among these studies, 17 Caryophyllaceae species were delimited using seed type, seed surface type, tubercle shape, surface granulation, suture outline, and hylar zone; 14 species from Asclepiadaceae and Apocynaceae on the basis of seed surface morphology; 11 species of Silene genus using seed micromorphological characters; genus Gypsophila and allied genera were delimited on the seed shape, size, length, epidermal cells shape, anticlinal wall, and testa cells (Amini, Zarre, & Assadi, ; Fawzi, Fawzy, & Mohamed, ; Gabr, ; Yildiz, ).…”

Seed shape, surface cells shape, arrangement, anticlinal wall pattern, and periclinal wall protuberances were recorded for nine species of Eucalyptus (Myrtaceae) using scanning electron microscopy to determine the importance of seed morphological characters as an additional tool for identification. Most of the seeds were found ovate and some seeds were elliptic and cuboid in shape. Almost reticulate regular seed surface patterns were observed. Four types of surface cells were examined; diamond, elliptic, oblong, and irregular. Majority of the seeds showed raised anticlinal wall level and diversity from wavy to puzzle in pattern. Periclinal wall may be glabrous or having protuberances that were rhombus and bullate in shape. Both macro-and micromorphological characters can provide basis for classification and delimitation of genus Eucalyptus. Research highlights• Seeds quantitative characters of nine Eucalyptus species as seed length, width, and weight.• Macromorphological characters of seeds including seed color, helium position, and seed shape.• Micromorphological characters include seed surface, periclinal wall, and anticlinal wall investigation under scanning electron microscope.• Ultra-seed sculpturing features as an additional tool in identification.

“…Anticlinal undulations and characters of cell boundaries in the seed exine are of high taxonomic significance and often characterize between the species and genus level (Barthlott &Voit, 1979 andBarthlott, 1981). Kaplan et al (2007) and Fawzi et al (2010) reported seed coat characters are successfully employed in the identification and classification of taxa.…”

T HE PLANT morphology, anatomical characters of stem and leaves, SEM of seed coat surfaces were used to reassess the conflicted taxonomic relationships between the genera Anthyllis, Hymenocarpos and Tripodion. Previous studies treated the genera Hymenocarpos and Tripodion as synonyms to Anthyllis. The present study clearly indicated considerably differences between the three genera. The most important characters used to distinguish the studied genera are habit, inflorescence type, bract shape, calyx, pod shape and seed coat pattern. On the bases of morphology, anatomy and seed characters, three distinct genera, Anthyllis, Hymenocarpos and Tripodion are represented in the Egyptian flora, each with only one species.

“…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, ).…”

Seed micromorphology of 13 species, belonging to four genera of subfamily Alsinoideae (Caryophyllaceae) were investigated with scanning electron microscopy (SEM), in order to assess their diagnostic significance at generic level and provide additional evidence on species delimitation, as well as correct identification and phylogenetic position. Genera and species of subfamily Alsinoideae exhibit great variation in ultrastructure and a high diversity of novel micromorphological characters were observed. Variation in seed shape, color, hilum, anticlinal wall, epidermal cell, cell surface, margins, and quantitative characters as length and width were studied in detail, compared, illustrated, and their taxonomic significant were discussed. Seed shapes of the species were classified as reniform, round, angular, subcircular, subreniform, and elliptical pyriform, with sub‐central, central, basal, and nearly basal hilum. Wavy, irregular, tetragonal, and elongated epidermal cells structure has been observed as an exomorphological character. The present findings show that the micromorphology of subfamily Alsinoideae provides taxonomic information and is helpful to distinguish different species. The results also explained that SEM morphology of seeds provide important data about affinity among taxa and give potential characters in delimitation of members of subfamily Alsinoideae at generic and species level. A principal component analysis allowed to highlight the most outsiders among seed micromorphology with a possible explanation. Taxonomic keys were developed based on micromorphological characters to delimit the species and useful for their quick identification within subfamily Alsinoideae.
