Impressions of fragments of vegetative organs of a few ferns are recorded from Lower Cretaceous sandstone<br />beds in Kurnub Formation, in Al Baqaa area, North Jordan. Spore-pollen assemblages, also indicating Early<br />Cretaceous age, were found in samples containing plant macro-remnants.<br /><br />

Five mosses are reported as new records to the Khartoum Province. This brings the number of fully identified<br />mosses known from this Province to 11 entities. The main floral elements in the studied localities are species of<br />Philonotis.<br />The total number of fully identified mosses, for the Sudan, is increased from 23 to 31 entities. Four of the<br />eight new to Sudan records resulted from this work while the other four were erroneously regarded earlier as<br />elements of the Egyptian flora.

The relationship among 15 samples representing 9 species and 8 sections of Plantago, based on electrophoretic<br />seed protein profile , as well as karyotype data is discussed in the light of their current sectional and sub sectional<br />delimitation. The delimitation of P. lanceolata as a separate identity from P. afra is congruent with the<br />taxonomic differences between these two species,while its separation from P. amplexicaulis and P. cylindrica<br />matches the cytological differences between them. The separation of P. alpina and P. coronopus based on the<br />electrophoretic pattern of their seed protein is congruent with the chromosomal differences between them, P.<br />alpina is a tetraploid with 2n=24 and a base number of X=6, whereas P. coronopus is diploid with 2n=10 and<br />X=5. The delimitation of P. afra supports its taxonomic separation from the other studied species. The pattern of<br />protein electrophoresis under reducing conditions distinguished P. major from the remaining species. This<br />separation is supported by the delimitation of this species in a separate section i.e. Plantago. The separation of P.<br />media from P. amplexicaulis and P. cylindrica by the analysis of protein pattern, under reducing condition,<br />confirms their separation based on morphological and chromosomal differences between them. Under nonreducing<br />condition P. amplexicaulis and P. cylindrica are separated together as one group distinct from P. major<br />and P. media which are delimited as another group

SDS-PAGE of seed protein profiles , SEM of seed coat surface patterns and selected macromorphological<br />characters were studied in the related taxa Caesalpinia gilliesii, C. pulcherrima, C. sepiaria and Delonix<br />regia. The obtained characters were used as one set of data and analyzed using the NTSYS-pc program.<br />The dendrogram produced showed a closer relationship between D. regia & C. pulcherrima. Taxonomic<br />relationships between the four taxa were discussed in the light of their morphological, anatomical,<br />embryological and phytochemical criteria. Merging of C. pulcherrima in the genus Delonix has been<br />suggested.

Criteria obtained by SEM of seed coat surface have been used to re-assess the taxonomic relationships between<br />19 species belonging to three subgenera of the genus Sesbania. The produced characters were analyzed by the<br />NTSYS-pc. program package using the UPGMA clustering method. The produced phenogram supported the<br />treatment of the three taxa Agati, Daubentonia and Sesbania as subgenera in the genus Sesbania. SEM criteria<br />have revealed that, the genus represent a natural monphyletic group and the subgenus Sesbania is the center of<br />the genus from which the other subgenera could have been evolved.

Vegetation and seed bank dynamics were undertaken in Wadi Fatima (western region of Saudi Arabia). 56<br />species representing 26 families of vascular plants are recorded in six community types dominated by Acacia<br />mellifera, Acacia tortilis ssp. tortilis, Rhazya stricta, Haloxylon salicornicum, Leptadenia pyrotechnica and<br />Senna italica, respectively. Assesment of soil seed bank was also undertaken
