The taxa are V. articulata, V. cassubica, V. villosa subsp. villosa in sect. Cracca, V. noeana var. noeana, V. sativa subsp. sativa, V. peregrina in sect. Vicia and V. caesarea in sect. Ervum. V. cassubica, V. noeana var. noeana, V. sativa subsp. sativa, V. caesarea have 2n = 12 chromosomes. V. articulata, V. villosa subsp. villosa, V. peregrina have 2n = 14 chromosomes in somatic cells. Total chromosome lengths range between 2.93-4.99 µm in V. articulata, 2.09-4.73 µm in V. cassubica, 1.86-3.36 µm in V. villosa subsp. villosa, 4.23-6.05 µm in V. noeana var. noeana, 2.07-3.72 µm in V. sativa subsp. sativa, 4.32-7.21 µm in V. peregrina and 2.39-5.78 µm in V. caesarea. The detailed chromosome measurements, relative lengths, centromeric indexes and karyotype asymmetries are also given. V. articulata is the most symmetrical karyotype, while V. villosa subsp. villosa is the most asymmetrical karyotype in intrachromosomal asymmetry including parameters of M CA , AsK, TF, Syi, A1, and A. However, the asymmetrical karyotypes are different in interchromosomal asymmetries. While V. noeana var. noeana is the most symmetrical karyotype in CV CL , Rec, and A2. V. caesarea is the most asymmetrical karyotype in only CV CL and A2. Unlike all parameters, V. cassubica is the most asymmetrical karyotype in Rec value. The scatter diagrams are given between M CA-CV CL and Syi-Rec.

Twelve morphometric characters are analysed with one-way analysis of variance and Tukey's honestly significant difference test for multiple comparisons. Polar axis and equatorial diameter of pollen grains range from 24.64 to 44.19 and from 15.90 to 30.42 mu m, respectively. The pollen grains are prolate-spheroidal to perprolate (P/E = 1.09-2.07), but the prolate shape occurs in the majority of the taxa. The regular pollen grains of all taxa are trizonocolporate, isopolar, and released in monads. Ornamentation of the mesocolpium is psilate-perforate in V. tenuifolia subsp. dalmatica and V. tenuifolia subsp. tenuifolia (sect. Cracca), reticulate-rugulate in V. villosa subsp. villosa (sect. Cracca), and reticulate-perforate in the remaining taxa. The apocolpium and colpus area are reticulate-perforate in V. hirsuta (sect. Cracca), V. ervilia (sect. Ervilia) and V. lunata subsp. grandiflora (sect. Trigonellopsis), and psilate, psilate-slightly perforate or perforate in the other taxa. The results obtained from analyses of pollen grains from the studied taxa of the subgenus Vicilla reveal significant differences in general morphology and some morphometric attributes, and ornamentation types. However, it is concluded that pollen morphology has proved to be uninformative for differentiating the subgenera Vicilla and Vicia.

These data were then synthesized to make taxon descriptions, keys, geographical distributions and ecological preferences. Since 2009, about 700 specimens have been collected from Central Anatolia and examined as the research materials. In addition, a large number of specimens have also been studied in the following herbaria ANK, GAZI, MUĞ, HUB and E. According to the Flora of Turkey (Davis 1985), there were 16 species found in Central Anatolia. But this study has shown that genus Vicia covers 22 species (V. noeana, V. anatolica, V. pannonica, V. hybrida, V. sericocarpa, V. narbonensis, V. galilaea, V. ervilia, V. caesarea, V. cracca, V. villosa, V. monantha, V. canescens, V. cappadocica, V. articulata, V. cassubica, V.peregrina, V. truncatula, V. grandiflora, V. lathyroides, V. cuspidata, V sativa) in ...

Maxted, Vicia L. and Narbonensis (Radzhi) Maxted sections of the genus Vicia L. subgenus Vicia (Fabeae, Fabaceae) naturally growing in Turkey has been studied using Light Microscopy (LM) and Scanning Electron Microscopy (SEM) to evaluate the taxonomic relevance of pollen characters. Twelve morphometric characters are analysed with one-way analysis of variance and Tukey’s honestly significant difference test for multiple compari- sons. Of the taxa studied V. narbonensis var. narbonensis (sect. Narbonensis) has the largest pollen grains (P = 51.98 lm 9 E = 30.52 lm) and V. lathyroides (sect. Wiggersia) has the smallest pollen grains (P= 27.71 lm 9 E = 20.14 lm). The pollen grains are sub- prolate to perprolate (P/E = 1.16–2.11), but the prolate shape occurs in the majority of the taxa. The regular pollen grains of all taxa are trizonocolporate, isopolar, and released in monads. Ornamentation of the mesocolpium is psilate-perforate in V. lathyroides (sect. Wiggersia), retic- ulate-rugulate in V. narbonensis var. narbonensis (sect. Narbonensis), (micro)reticulate in V. sericocarpa var. se- ricocarpa (sect. Hypechusa), V. sativa subsp. sativa (sect. Vicia) and V. grandiflora var. grandiflora (sect. Vicia), and
reticulate-perforate in the remainine taxa. The apocolpium and colpus area are psilate or perforate in all taxa except V. sericocarpa var. sericocarpa (sect. Hypechusa) and V. sativa subsp. sativa (sect. Vicia), which exhibit the obscurely reticulate-perforate pattern. Several palynologi- cal features have taxonomic importance in sectional level: polar axis, equatorial diameter, pollen shape (P/E ratio), colpus length, colpus width, size of pori, porus length/ width ratio, lumina diameter, muri thickness and orna- mentation. The results also indicate that pollen characters can be useful in distinguishing the examined taxa.
