Bocconea 25, Results of the Seventh Iter Mediterraneum Bocconea 25: 5-127 doi: 10.7320/Bocc25.005 Version of Record published online on 9 July 2012 Werner Greuter Results of the Seventh “Iter Mediterraneum” in the Peloponnese, Greece, May to June 1995 (Occasional Papers from the Herbarium Greuter – N° 1) Abstract Greuter, W.: Results of the Seventh “Iter Mediterraneum” in the Peloponnese, Greece, May to June 1995. (Occasional Papers from the Herbarium Greuter – N° 1). — Bocconea. 25: 5-127. 2012. — ISSN 1120-4060 (print), 2280-3882 (online). The material collected during OPTIMA’s Iter Mediterraneum VII to the Peloponnese in 1995 has been revised. It comprises 2708 gatherings, each with 0 to 31 duplicates, collected in 53 numbered localities. The number of taxa (species or subspecies) represented is 1078. As many of the areas visited had been poorly explored before, a dozen of the taxa collected turned out to not to have been previously described, of which 9 (7 species, 2 subspecies) are described and named here (three more were published independently in the intervening years). They belong to the genera Allium, Asperula, Ballota, Klasea, Lolium, Minuartia, Nepeta, Oenanthe, and Trifolium. New combinations at the rank of subspecies (3) and variety (2) are also published. One of the species (Euphorbia aulacosperma) is first recorded for Europe, and several are new for the Peloponnese or had their known range of distribution significantly expanded. Critical notes draw attention to these cases and to taxonomic problems yet to be solved. An overview of the 11 Itinera Mediterranea that have taken place so far is presented, summarising their main results. Keywords: Flora of Greece, Peloponnese, Itinera Mediterranea, OPTIMA, new species, new com- binations, Allium, Asperula, Ballota, Klasea, Lolium, Minuartia, Nepeta, Oenanthe, Trifolium.

Introduction Iter Mediterraneum VII, organised by the Department of Botany, Patras University, under the auspices of the Organisation for the Phyto-Taxonomic Investigation of the Mediterranean Area (OPTIMA), took place from 30 May to 15 June 1995. During slightly more two and a half weeks it visited parts of the Peloponnese, the southernmost part of 6 W. Greuter: Results of Iter Mediterraneum VII non-insular Greece. When planning the itinerary, the Organisers kept in mind the basic purpose of the Itinera Mediterranea: to explore areas little visited by botanists so far and poorly represented in botanical collections. In this, they fully succeeded. While on the one hand, by leaving aside the classical, floristically rich but well explored localities, they for- sook the collecting of several local but well known endemics, on the other hand they dis- covered no less than a dozen so far undescribed taxa and found new localities for several known ones, often expanding considerably their known distributional ranges. Speaking of Organisers, mention must be made in the first place of one who avoided the limelight of official responsibility but advised actively and knowledgeably from be- hind the scene: Dimitrios Phitos, head of the Department of Botany of Patras University and OPTIMA’s immediate Past President at that time. Georgia Kamari, his spouse, was in the lead of the Iter’s organising committee, of which the other members were Dimitrios Christodoulakis, Theophanis Constantinidis, and Anastasios Anagnostopoulos. All four, taking turns, acted as excursion leaders and guides for part of the excursion, assisted for four days (6 to 9 June) by Gregory Iatrou. All of them were members of the Department of Botany of Patras University, which served as the Iter’s headquarters and offered its in- frastructure and logistic facilities for free – a major asset when one thinks of the consider- able bulk of the material collected. A short history and synopsis of Itinera Mediterranea The plan to organise a series of annual botanical expeditions under the auspices of OP- TIMA took its origin in that Organisation’s Commission for Floristic Investigation, then placed under the active and enthusiastic leadership of Benito Valdés. Approved in princi- ple at the V OPTIMA Meeting in Istanbul in 1986, the plan was fleshed out at a meeting held in Sevilla in May 1987, to be made public in the following year (Valdés 1988a, b). The declared purpose of the Itinera Mediterranea has been: (a) to study and collect plants from poorly known areas, (b) to study areas which, while locally well known, have been but little explored by botanists at large, and (c) to enable young Mediterranean bota- nists to gain field experience in other Mediterranean countries. To promote the last named aspect, half the places for participants (6 for a total of 12) were reserved to “junior” bota- nists, who were in a way subsidised by the “senior” participants by paying, among them, for one third of the expedition costs against the two thirds funded by the seniors. Also, small grants were made available to junior participants by OPTIMA. The idea of these Itinera was well received and proved very successful. In spite of the cost and labour involved, 11 expeditions took place between 1988 and 2002, all extremely successful, last not least in terms of the amount and quality of material collected. The main stumbling block proved to be the handling of the material once dried (separation of duplicate sets, identification, labelling, packing, and mailing). This process often lagged behind by years, causing discontent and eventually loss of interest from side of some par- ticipants and the institutions supporting them. Yet, for anyone who (like me) had to handle that task, the reasons are obvious. My estimate is that, per expedition, at least one person- year was necessary to accomplish the task, which requires good technical and in part sci- entific skills. Bocconea — 25 7 As there is no complete record of all 11 Itinera Mediterranea that took place so far, and as indeed some information regarding them has never been published, I take advantage f the present opportunity to bring together in a single synopsis at least the basic facts. In or- der to do so, I had to rely on the help of several leaders or key players of past Itinera, which they unselfishly offered and to which I am much indebted on that account; to name: Gabriel Alziar, Nice; Gianniantonio Domina, Palermo; Stephen Jury, Reading; Dimitar Uzunov, formerly Sofija; Benito Valdés, Sevilla; Olja Vasić, Beograd; and Ernst Vitek, Wien.

It is a predominantly flat land with several shallow depressions, which act as seasonal wetlands after monsoon and during winter its converts into sedge mixed grassland, an ideal dual ecosystem. An attempt was made to document ecology, biomass and community based assessment of grasses in Banni, we surveyed systematically and recorded a total of 49 herbaceous plant species, being used as fodder by livestock. In which, the maximum numbers of species (21 Nos.) were recorded in Echinocloa and Cressa habitat; followed by Sporobolus and Elussine habitat (20 species); and Desmostechia-Aeluropus and Cressa habiat (19 species). A total of 21 highest palatable species were recorded in Echinocloa-Cressa communities followed by Sporobolus-Elussine–Desmostechia (20 species and 18 palatable species) and Aeluropus–Cressa (19 species and 17 palatable species). For long-term conservation of Banni grassland, we also suggest a participatory co-management plan.

Recent studies have shown that, the expression levels of common housekeeping genes are varying in different tissues and experimental conditions. The genomic DNA contamination in RNA samples is another important factor that also influence the interpretation of the data obtained from qPCR. It is estimated that the gDNA contamination in gene expression analysis lead to an overes- timation of the RNA transcript level. The aim of this study was to validate the most stably expressed reference genes in two different tissues of Aeluropus littoralis—halophyte grass at salt stress and recovery condition. Also, a qPCR-based approach for monitoring contamination with gDNA was conducted. Results: Ten candidate reference genes participating in different biological processes were analyzed in four groups of samples including root and leaf tissues, salt stress and recovery condition. To determine the most stably expressed reference genes, three statistical methods (geNorm, NormFinder and BestKeeper) were applied. According to results obtained, ten candidate reference genes were ranked based on the stability of their expression.

Accepted 6 May, 2011 Seeds of 48 species of Poaceae were examined for the presence of alkaloid, protein, fats and oil, inulin, starch and tannins. All taxa investigated indicated the presence of starch, fats and oils and protein and were devoid of tannins and inulin. Only 12 seed samples indicated the presence of alkaloids. The Positively indicated taxa are suggested for further investigation. Key words: Poaceae, starch, fats and oils, alkaloid, protein, tannins, inulin. INTRODUCTION Ergastic substances are products of metabolism. These reserve (Abelson, 1978). substances may appear or disappear at different times in From the beginning, seeds have been and still are the the life of the cell. They are reserve or waste products main source of man’s diet. The Poaceae (large seeded resulting from cellular activities. Some well-known grasses) contribute more food seeds than any other plant ergastic substances are carbohydrates, cellulose and family; it contributes about 50% per capita energy intake starch, protein bodies, fats and related substances (FAD, 1977). (Eckey, 1954; Pritchard, 1997; Arahira et al., 1998; The importance of the nature of ergastic substances in Christina et al., 2001; Gómez-Sosa and Castro, 2004; plant taxonomy has been stressed by various authors Wolf, 2006).
