“…Calcium oxalate crystals in S. tatarica can help prevent infections, as was also suggested by Werker (1997) and Tillman-Sutela and Kauppi (1999). The endosperm and perisperm in these seeds are typical of the Caryophyllaceae (e.g., Melzheimer 1977;Aeschimann 1984;Werker 1997;Hong et al 1999).…”

Certain morphological and anatomical structures of riparian plants might be important for their survival during the season when they are exposed to severe stress caused by flooding, burial, fluctuating temperatures, and drought. These rare characteristics were studied as related to their ecological consequences in a threatened plant, Silene tatarica (L.) Pers., in riparian and ruderal habitats. The main differences between the habitats were morphological and closely related to the habitat properties, whereas the basic anatomy of structures was similar. After sand burial, most riparian plants formed vertical rhizomes and new meristems by bud ramification in the stem base near the ground surface. Special anatomical structures of fleshy underground stems and roots seem to allow plants to be resilient. Moreover, some primitive structures, such as vascular elements with helical and scalariform thickenings, collenchyma, and abundant xylem parenchyma, may increase the resilience of organs. High amounts of saccharose in fleshy rhizomes and roots can increase the cold resistance of plants. The flat shape and structures of tiny seeds may enhance the long-distance dispersal by water. We suggest that the synergism of these structures enables the survival of S. tatarica in highly disturbed habitats with fluctuating water levels.Résumé : Chez les plantes riveraines, certaines structures morphologiques et anatomiques peuvent être importantes pour leur survie au cours de la saison, lorsqu'elles sont exposées à des stress importants, causés par l'inondation, l'enterrement, les fluctuations de température et la sécheresse. Les auteurs ont étudié ces caractéristiques rares, en relation avec leurs conséquences écologiques chez une plante menacée, le Silene tatarica (L.) Pers., dans des habitats riverains et rudéraux. Les principales différences entre les habitats sont morphologiques et étroitement reliées aux propriétés de l'habitat, alors que les structures de base de l'anatomie sont les mêmes. Suite à l'enterrement, la plupart des plantes riveraines forment des rhizomes verticaux et de nouveaux méristèmes par ramification de bourgeons à la base de la tige, près de la surface du sol. Des structures anatomiques spéciales, au niveau des tiges et racines souterraines charnues, semblent conférer de la résilience aux plantes. De plus, certaines structures primitives, telles que les élé-ments vasculaires munis d'épaississements hélicoïdes ou scalariformes, les collenchymes et un abondant parenchyme du xylème, peuvent augmenter la résilience des organes. La présence de grandes quantités de saccharose dans les rhizomes charnus et les racines peut augmenter la résistance au froid des plants. La forme et les structures aplaties des très petites graines peut augmenter leur dispersion par l'eau sur de longues distances. Les auteurs suggèrent que le synergisme de ces structures rend possible la survie du S. tatarica dans des habitats fortement perturbés par des fluctuations du niveau de l'eau.

“…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.

“…We observed variation in all species of which more than one population was examined, and we abstained from constructing groups due to instability of seed characters and studying 24 taxa from only a single population while 15 taxa were from more than one population. The single exception for the family Caryophyllaceae is a paper by Hong et al (1999), who did not report any intraspecific variations in 8 Korean Silene species although they worked mostly on 2 populations per taxon and the main grouping character was dorsal groove of seed, either distinct or not distinct, which is closely related to ridge pattern. Distinction level of the dorsal groove is proportional to the appearance of the ridge.…”

“…Ghazanfar (1983) worked on 75 taxa of perennial Silene, which she assigned to 5 types depending on seed morphology. Hong et al (1999) worked on 8 Korean Silene species. They grouped them mainly into 2 types and prepared an identification key based on seed morphology.…”

Some species of Silene form a complex, since they are separated from each other by only small morphological differences, which may intermix or overlap. In particular, anthophore length, capsule length, and leaf width are used to differentiate species on millimetric scales (Coode and Cullen, 1967). Therefore, the identification of these species may be difficult, especially when they show great variation.Seed macro-and/or micromorphology is an alternative or additional tool to delimit taxa, and sometimes the seed characters alone are satisfactory (Dadandı et al., 2009). Seed morphology has been examined and interpreted in many other genera of Caryophyllaceae such as Gypsophila L.
