Synonyms reported only from Egypt are given in a separate list. The distribution of the 181 mosses in the 11, hitherto, surveyed phytogeographic territories of Egypt shows that S, Mm, Cai and Di are the richest territories regarding the number of recorded taxa. Pottiaceae, Bryaceae and Funariaceae dominate the flora. Poh/ia lescuriana (Sull.) Oehl is a new record to Egypt. Other relevant annotations are also given.Cairo University Herbarium (CAI)Taeckholmia1110-741335120151201Identification of pollen grains of some species of Eugenia and Syzygium (Myrtaceae) using Fourier transform infrared spectroscopy25431214810.21608/taec.2015.12148ENHebaElazabDepartment of Botany, Faculty of Science, Ain Shams UniversityJournal Article20150714Four plant species have been collected from the parks and botanic gardens in Egypt; namely: <br />Eugenia supraxillaris, Eugenia uniflora, Syzygium cumini, Syzigium jambos. These species were <br />tentatively selected from the two genera Eugenia and Syzygium for studying their pollen morphology. <br />Farther, their pollens have been undertaken as modules representing preliminary trials to test the <br />efficiency of the Fourier transform infrared (FT-IR) spectroscopy as a tool for pollen grains <br />identification. This methodology is applied as a novel tool to screen the chemical compositions of <br />pollen grains. In case of successful application of this method, a larger number of Myrtle taxa can <br />be subject to future studies for unraveling the knots of controversy and taxonomic arguments about <br />the stability or segregation of some species of the two genera mentioned above. Pollen samples, <br />belonging to the four species under investigation, were examined with light photomicroscope as <br />regards to some morphological features, principally: pollen shape; size; aperture characters; and <br />pollen class. The results obtained showed that the pollens of the examined species were <br />oblatespheroidal toprolate spheroidal in shape. Tricolporate and tetracolporate types were detected <br />in all the studied taxa. FT- IR identification revealed that all the studied species<br /> were closely similar with regard to their chemical compositions. Thus, the results obtained at this <br />stage might assume that the pollen grains of the Eugenia and Syzygium species under investigation <br />exhibit close similarity.Cairo University Herbarium (CAI)Taeckholmia1110-741335120151201Flora and vegetation of the different habitats of the western Mediterranean region of Egypt.45761221610.21608/taec.2015.12216ENDaliaAhmedBotany Department, Faculty of Science, Tanta UniversityKAMALSHALTOUTBotany Department, Faculty of Science, Tanta University, Tanta, EgyptHasnaaHosniBotany Department, Faculty of Science, Cairo University, Cairo, Egypt.R.El-FaharBotany Department, Faculty of Science, Tanta University, Tanta, EgyptJournal Article20150818 <br /> The present study aims to assess the relation between the floristic composition and the different habitats charcterizing the western Mediterranean region of Egypt, determine the community types that dominate the study area; and evaluating the rarity of the recorded species. Nine hundred and sixty eight species (belonged to 429 genera and 97 family) were recorded; 363 species were restricted to one habitat, while only one species occured in all the 13 habitats. Asteraceae had the highest contribution, followed by Fabaceae, Poaceae and Brassicaceae. The most represented life form was therophytes, while parasites were the least. Six habitat groups were resulted after the application of 1WINSPAN and DCA. Mediterranean elements were the most represented, followed by Irano-Turanian, but Sudano Zambezian elements were the least. Twenty endemics and 21 near endemic species were recorded. Species which had small geographical distribution, narrow habitat specificity and were non-abundant (SNN) were the most represented, while species had large geographical distribution, wide habitat specificity and non-abundant (LWN) were the least. Forty one species were recorded as introduced species in the study area. Therecent land use led to the emergence of new invasive species, which may severely affect the plant diversity and community structure of the study area.Cairo University Herbarium (CAI)Taeckholmia1110-741335120151201Diversity of crop plants in Nile Delta, Egypt77971221910.21608/taec.2015.12219ENM.El-BeheiryBotany Department, Faculty of Science, Tanta University, Egypt.DaliaAhmedBotany Department, Faculty of Science, Tanta UniversityEsraaAmmarBotany Department, Faculty of Science, Tanta University, Egypt.KamalShaltoutBotany Department, Faculty of Science, Tanta University, Egypt.Journal Article20150920 <br /> This study aims to answer the following questions: 1- what are the crop diversity<br />and distribution in Nile Delta and its outskirts?, 2- what are their annual cyclic distribution? <br />and 3- what are the economic goods and environmental services which they offer?. One hundred field <br />trips were conducted to many districts in Nile Delta including Greater Cairo and Alexandria during <br />summer 2012 to spring 2014. One hundred and seventy three crop species belonging to 99 genera and <br />44 families were recorded. Poaceae was the most represented family, where Cucumis was the most <br />represented genus. Herbaceous plants were the most represented, followed by trees and shrubs. The <br />period from March to May was characterized by the highest flowering activity. Most of the species <br />were propagated by seeds (86.9%), followed by cutting (13.2%). Twenty two groups of crops were <br />resulted after the application of TWINSPAN and DCA: 6 groups occurred in only one district, 3 in 2 <br />districts, and another 3 in > 10 districts. Group 10 that included 13 districts had the highest <br />species richness (67.9 species region-'), while G 11 that included 20 districts had the highest <br />species turnover (3.7). Of the 173 crop species recognized in Nile Delta, 82.1 % had at least one potential or actual economic good. Food plants were the most common crops, while grazing plants were the least. Inaddition, 64.2 % of the crop species had at least one environmental service; cold-tolerant plants were the most represented, while the sand accumulators were the least. This study is the first attempt to evaluate the agro-diversity in Nile Delta and introduces for the scientific community a baseline data for evaluating the agro-biodiversity in Egypt as a whole.Cairo University Herbarium (CAI)Taeckholmia1110-741335120151201Floristic Diversity and Vegetation Analysis of Wadi Sudr, South-West Sinai Peninsula.991191222310.21608/taec.2015.12223ENAmal A.MorsyFaculty of Science- Ain Shams University.HematKhatabFaculty of Science- Ain Shams University.Esraa A.El SherbinyEcology and dryland agriculture division, Desert Research Center.JasminEldemirdashEcology and dryland agriculture division, Desert Research Center.Journal Article20180902<br />This study evaluated the effect of edaphic factors on species diversity and distribution of <br />vegetation in Wadi Sudr, Sinai Peninsula. The study included 21 stands, 54 species<br />belonging to 44 genera and representing 22 families, where the abundant family was Zygophyllaceae <br />comprising 15% of the total number of the recorded species. Chamaephytes were the dominant life <br />forms in the studied Wadi (55.56%). Chorological analysis showed the dominance of the monoregional <br />Saharo-Arabian chorotype (46.3%). TWINSPAN classification separated five vegetation groups which <br />included: (I) Zygophyllum album, (II) Haloxylon salicomicum, (III) Retama raetam, (IV) Reaumuria <br />hirtella and (V) R raetam. CCA analysis indicated that the vegetation group representing the <br />downstream of Wadi Sudr was affected by soil chemical properties, whereas CaC03% and physical <br />properties affected the vegetation groups representing the up and midstream parts of the Wadi.
