An updated list provides information concerning the, hitherto, known Egyptian mosses (168 taxa). Reference is<br />made to new records (20 taxa), phytogeographical territory(ies) from which each moss has been recorded, and<br />other relevant data.<br />An annex to the main list includes the excluded taxa, which are 16 entities and are either nomina<br />nuda, misidentified or, hitherto, recorded from only greenhouses and gardens or from beyond Egyptian<br />boundaries.<br />An appendix including 67 reference works dealing entirely or partly with Egyptian mosses is also<br />provided.

Macromorphological characters, SEM of seed coat surface criteria, seed coat anatomy and seed protein<br />electrophoresis aspects, were used to re-assess the taxonomic relationships between the genera Chaenomeles and<br />Cydonia. Characters were analyzed by the NTsys-pc. program package, using the UPGMA clustering method.<br />The dendrograms produced were discused and showed a close relationship between Chaenomeles sinensis<br />Koehne and Cydonia oblonga Miller. The result gives support to the merging of the former taxon in the genus<br />Cydonia as presented in Mabberley (1997).

The secondary xylem elements show apparent constancy in their characters among the indiginous species of<br />Tamarix. These characters were studied to evaluate their taxonomic importance. The characters of vessels (width<br />in cross section and number/mm2) were found important at the sectional level, while characters of rays and fiber<br />thikness could be important for the distinction of certain species. Wood anatomical characters were found useful<br />for the identification of Tamarix species when reliable morphological characters such as flowers and fruits are<br />not available. In this respect, such characters would be useful for the identification of archaeological worked,<br />non-worked wood material and charcoal.

The idiginous taxa of Malvaceae represented in the flora of Egypt were systematically revised. This revealed the<br />presence of 26 species belonging to 11 genera and four tribes; among these, Malvella sherardiana ia a new<br />record to the flora of this country.<br />For each species, valid name, synonymes (if any), type, distribution (local and global) and selected<br />specimens are given. A key for the genera of the family, and keys for the species belonging to the genera with<br />more than one species are provided

The pollen grains of 22 species bolonging to 10 genera of Malvaceae which are represented in the flora of Egypt<br />were studied using light microscope (LM). The pollen grains are spheroidal, relatively large with numerous<br />pores scattered irregularly all over the grain, sculpturing is echinate. Pollen morphological differences were<br />found useful when combined with other gross morphological characters to distinguish between certain taxa.

The morphological and anatomical characters of the spermoderm of 49 native and foreign taxa in Wettstein’s<br />tribe Solaneae were investigated for their delimitation as well as for a speculation of their phylogenetic status.<br />The observations culminated into the suggestion of an identificatory key. Taxonomic changes including<br />transference (re-allocation) and addition were done for some taxa. Nomenclatural amendments for some other<br />taxa were suggested and a new species, Atropa lutea, has been reached at. The phylogenetic status of the studied<br />taxa was speculated relying on the number of the spermoderm layers. Multi-layered spermoderm was considered<br />less advanced than the few-layered one.

Twenty-four out of 26 mosses, recently collected from the United Arab Emirates (UAE), are new records for the<br />country and the total number is raised to 27 entities. Six of these mosses and Riccia subbifurca Warnst. ex Croz.<br />are new records to the whole Arabian Peninsula. Upward-growing peculiar aerial rhizoids are recorded in six of<br />the mosses. Reference to sporulation, sexual and asexual reproductive structures are made.

Taxonomic relationships in eight species belonging to five of the 13 currently recognized sections of the genus<br />Lathyrus have been discussed and their phylogeny based on chromosomal criteria is suggested. A diploid<br />number of 2n = 14 (x = 7) has been found in all species studied and thus x = 7 is confirmed as the basic number<br />in the genus. Karyotypes of the examined species have metacentric and submetacentric chromosomes that are<br />variable in length. The retention of L. pratensis in the section Pratensis is confirmed. The assignment of L.<br />hirsutus to section Lathyrus and of L. cicera and L. sativus to section Clymenum are supported. The present data<br />revealed that L. pratensis is the most likely ancestral type in the genus and that Layhyrus represents a natural<br />monophyletic group in the tribe Vicieae.

This study deals with species diversity of ruderal habitats in Nile Delta region. Over 400 stands, representing 18<br />habitats, were sampled in the study area. Of the 248 species encountered, few were common throughout all<br />habitats. Annuals were more represented along the terraces of highway roads, solid refuse areas and trampled<br />fields, while perennials were more represented along the slopes and depressions of old roads in railway yards.<br />The diaspores of more than half of the recorded species are microschlerochores (light diaspores), ballochores<br />(diaspores with explosion mechanisms) and pogonochores (diaspores with long hairs). For almost-all habitats,<br />species diversity was higher in spring than in the other seasons, particularly summer and autumn. Communities<br />of abandoned salinized fields, terraces and depressions of highway and railway roads had the highest species<br />diversity, while those of trampled fields, trampled railway yards, terraces, slopes and depressions of old roads<br />had the lowest.

This<br />revealed the presence of 50 species belonging to 16 genera, 8 tribes and 3 sub-families. Kickxia gracilis, K.<br />pseudoscoparia, Scrophularia sinaica, Veronica scardica and V. rubrifolia are new records to the flora of this<br />country.<br />For each species, valid name, synonymes (if any), type, distribution (local and global) and selected<br />specimens are given.
