“…Studies of seed morphology are based on the combination of different qualitative characters and directed towards understanding the phylogenetic relationships between taxonomic groups. In addition, two particular strategies applied are as follows: (1) A general description of seed morphological types and, (2) The definition of surface characters, such as for example seed tubercles in the Caryophyllaceae [26][27][28][29][30][31]. In both cases, descriptions are based on adjectives, and progress is often hampered by the lack of quantification methods.…”

The Cucurbitaceae is a monophyletic family with close to 1000 species of climbers, including important agronomic species and varieties characterized by tendrils and pepo fruits. The seed’s morphology is varied, and the development and structure of the seed coat have been described in detail on some species. Overall description of the seed shape is based on terms comparing it with geometric figures, but quantitative methods are lacking in the literature. Here we apply a general morphological analysis to seeds of representative genera of the Cucurbitaceae, followed by curvature analysis in the poles and symmetry analysis. These methods are useful for the quantitative description of seed shape and the comparison between species and varieties. Differences between species were found for most morphological measurements, as well as for symmetry and curvature values. The comparison between three species of Cucumis (Cucumis sativus, C. myriocarpus and C. melo) and two varieties of C. melo reveals differences between species and varieties both in curvature and symmetry. The results obtained from both methods, curvature and symmetry analysis, form similar groupings in a cluster analysis. The methods described here were applied for the identification of agronomic varieties and the quantitative description of seed shape in taxonomy.

“…Apart from a few exceptions (Petrorhagia alpina, Agrostemma githago), previous studies have demonstrated that Caryophyllaceae pollen is usually of medium size, ranging from 25 to 50 (65) μm in diameter (Yildiz, 2001a, b;Perveen and Qaiser 2006;Ataşlar et al, 2009;Yildiz et al, 2010;Poyraz and Ataşlar, 2010). Ataşlar et al, (2009) specified that grains range from 24 to 65 µm in diameter if pantocolpate and pantoporate, and from 12.5 x 8 µm to 28 x 23 µm if tricolpate or triporate.…”

The pollen morphology of Dianthus petraeus (Caryophyllaceae), which is endemic to the Balkans, has been examined by both light and scanning electron microscopy in order to provide taxonomically valuable characters that might be used in the classification of the Caryophyllaceae, as well as to contribute to the pollen atlas of Serbian apiflora. The pollen grains of D. petraeus are radially symmetrical, apolar, spheroidal and medium-sized. The mean of the pollen diameter is 45.5?1.4 ?m. The sculpturing pattern of exine is microechinate-microperforate, and the tectum is covered with minute echini averaging 0.8?0.1 ?m in length, more or less evenly distributed between the perforations. The microechini average number per sample area of 5 ?m x 5 ?m is 3.2?0.6. In view of the number, position and type of the apertures, the grains are polypantoporate, with about 13 operculate pores, averaging 6.4?0.7 ?m in diameter. Each operculum is covered with 4-6 conical spinules, which are longer than those on the exine surface. The mean interporal distance is 13.3?1.3 ?m. The obtained palynological results provide information that contribute towards a better understanding of the taxonomic status of D. petraeus.

In the Caryophyllaceae, seed surfaces contain cell protrusions, of varying sizes and shapes, called tubercles. Tubercles have long been described in many species, but quantitative analyses with measurements of size and shape are lacking in the literature. Based on optical photography, the seeds of Silene were classified into four types: smooth, rugose, echinate and papillose. Seeds in each of these groups have characteristic geometrical properties: smooth seeds lack tubercles and have the highest values of circularity and solidity in their lateral views, while papillose seeds have the largest tubercles and lowest values of circularity and solidity both in lateral and dorsal views. Here, tubercle width, height and slope, maximum and mean curvature values and maximum to mean curvature ratio were obtained for representative seeds of a total of 31 species, 12 belonging to Silene subg. Behenantha and 19 to S. subg. Silene. The seeds of the rugose type had lower values of curvature. Additionally, lower values of curvature were found in species of S. subg. Silene in comparison with S. subg. Behenantha. The seeds of S. subg. Behenantha had higher values of tubercle height and slope and higher values of maximum and average curvature and maximum to mean curvature ratio.
