Salicornia Sect. Dolichostachyae consists of approximately ten species which are mainly
distributes in lower parts of coastal salt marshes in Eurasia. Taxonomy of the section is
problematic like the other sections of the genus and very little known about the section from
Turkey. Before our study, known species of the section from Turkey are S. fragilis Ball & Tutin
and S. dolichostachya Moss. without certainty. We determined S. fragilis as a doubtfull record
and confirmed the presence of S. dolichostachya Moss. and recorded S.emerici Duval-Jouve as a
new species record from Turkey. Finally three species belonging to this section recognised from
Turkey, namely: S. dolichostachya, S.emerici and S.freitagii Yaprak & Yurdakulol.
Chromosome number of S. dolichostachya, S.emerici are reported first time from Turkey and
S.freitagii first time for science. We have discussed morphological and ecological characteristics
of these species. Since rDNA ETS sequences of these species are identical, Amplified fragment
length polymorphisms (AFLP) were utilized to examine systematic relationships in the section.
Keywords: Chenopodiaceae, Salicornia, Dolichostachyae, Turkey, AFLPs

Botanists have been interested in Mediterranean bulbs for a long time. In spite of numerous, and
quite complete, studies about some genus (Tulipa, Iris, Crocus, Narcissus, Scilla, etc.), our
knowledge about systematic, distribution, or populations state of conservation remain
incomplete.Even recent monographs about some genus are far from solving all the taxonomic and
field identification problems. Furthermore, we poorly know the threats concerning those species
(horticultural collects, urbanization, agricultural changes, etc.). Chromosomal studies, and more
recently DNA studies, improved our knowledge in bulbous species. For a few years, genome size
investigations also allowed us to consider the geophytes with a new approach. 2C DNA values
open new perspectives in the study of geophytes diversity (field inventories, identification,
conservation, etc). The recent studies on Colchicum, Narcissus, Arum show the interest of flow
cytometry.
Keywords: Mediterranean, bulbous geophytes, DNA amount, flow cytometry.
