In order to find new suitable characters in the taxonomic delimitation of the genus Quercus, whose hardness is well known, Quercus xfontanesii, endemic to Sicily, has been studied in comparison with its parents, i.e. Q. gussonei, which is close to Q. cerris, and Q. suber. These taxa are here delimited as far as taxonomy, ecology and Sicilian distribution are concerned. Furthermore, the results of SEM microstructure analysis of leaves and xylem anatomy are illu- strated and commented. The analysis of the leaf microstructures shows that there is a remarkable similarity between the stomata and stellate trichomes of Q. xfontanesii and both the parental species, as the trichome rays are numerically intermediate in the nothotaxon. Also xylem anatomy in Q. xfontanesii results intermediate between both the parents. In particular, the qualitative analysis of the transverse sections on earlywood and latewood shows that the vessel distribution in Q. xfontanesii gives origin to a structure with intermediate features between a diffuse porous wood (Q. suber) and a ring porous wood (Q. gussonei). The quantitative analysis, based on the maximum and ‘minimum diameter, surface and shape factor, confirms the conclusion stated above. In particular, the minimum diameter of the wood vessels is the most significant parameter. The frequency distribution shows an increase in the number of vessels in Q. xfontanesii, from earlywood to latewood, differently from the two parental s...

Campylopus oerstedianus has recently been collected for the first time in Sicily. lt is a rare species known from isolated localities in Europe, Costa Rica, Jamaica and North Carolina. This new record suggests that C. oerstedianus is possibly in spreading in the european part of its range. As the scattered distribution in the Caribbean and Mediterranean areas is concemed, this suggest a range of circum-Tethyan origino

Seed proteins of eleven species of Brassicaceae were investigated by polyacrylarnide gel e1ectrophoresis. In tota! 50 different bands were identified. Some ofthe bands are characteristic and represent constant markers of each species, which allow the unequivocal identification of their electrophoregram. The obtained data have been treated numerically using the cluster analysis method of unweighted pair group (UPGMA). The electrophoregrarn gives support to the idea that the tribe Sisymbrieae is an unnatural group and suggests its merge with the tribe Brassiceae. On the other hand the distinct position of Zilla spinosa in the dendrograms supports the traditional treatment of this taxon as a monotypic subtribe Zillinae.

Results of revision of Bulgarian parasitic fungi (Peronosporales, Ascomycetes, Urediniomycetes, Ustomycetes and mitosporic fungi) preserved in of BUCM are presented. 17 species and 45 fungus-host combinalions are reported as new lo Bulgaria.

During the preparation of the list of species in the Flora palaestina area, several hundred names have been changed, added or replaced. Due to the limited space in the scheduled first part ofthe second edition ofFlora Palaestina, the author lists the comments concerning many of the new names in Flora Palaestina.

The author reports on the results obtained by applying the CSR model to the flora of the Isola Piana (NW Sardinia). The R strategy, which includes the plant speeies which live in habitats with frequent disturbances and which are characterised by a short life cycle and abundant seed production is the most widely represented. The triangular arrangement has also been applied to the main systematic groups and in particular, to endemic species which, because they occupy particular ecological niches and differ for the strategy from the other species.

A new Sideritis species is described and illustrated. The new taxon, belonging to the sect. Empedoclia (Raf.) Benth., is endemic to Turkey.

Scanning electron microscopic investigation of seed and capsule morphology of Arenaria serpyllifolia L. and A. leptoclados Guss. In the Caryophyllaceae have been studied. Seed size in both species show consistency, but testa ornamentation (midzone) vary in shape even in the seeds from one capsule of A. serpyfolia, while in A. leptoclados midzone cells are narrowly elongate in different populations and environments. The ripe capsule teeth ornamentation has a diagnostic character to separate A. serpyllifolia and A. leptoclados.

Actinotaenium cruciferum, Cosmarium variolatum, Euastrum binale var. guhvinskii. E. luetkemuelleri var. carniolicum, E. luetkemulleri var. floridanum and E. obesum have been recorded for the first time in Turkey.

This study deals with the co-evolutionary determined interrelationships between the complex of plants flowering in mid-summer on the southern limestone slopes of Vitosha Mts. and their pollinating agents. The most numerous are the plant species with flag and gullet (zygomorphic) blossoms. Numerous are also the plants with dishlbowl (actinomorphic) blossoms. As a whole dominate the purple coloured blossoms, followed by the yellow ones. The pollinators visit most actively the plants with zygomorphic blossoms, mainly those that are purple in colour. Most numerous pollinators ofthe entomophilous plant complex flowering in the mid-summer on the southern limestone slopes of Mt. Vitosha are bees.

The results of a fourth floristic investigation of Cyprus are presented with notes on 159 taxa. Two new combinations are made: Pinus pallasiana subsp. caramanica and Ranunculus cyprius; Lathyrus aphaca subsp. cyprius is described as new. Bassia indica, Fumaria capreolata and Galium divaricatum are reported as new for the Greek part of Cyprus and Lolium multiflorum subsp. gaudini is found new for all Cyprus. Many taxa are reported as new to one or more of the eight botanical divisions of Cyprus. The presence of some taxa has been confirmed after a long time. The chorology of some species is discussed in detail.

We report on a new loeality of Quercus trojana subsp. euboica, endemic oak of the Island of Evvia (Euboea), Greece. Q. trojana subsp. euboica was found on serpentine (peridotite) near the town of Prokopi, northern Evvia in undergrowth of open Pinus halepensis wood. Phytosociologieal-status of Q. trojana subsp. euboica and syntaxonomy ofthese Evvian Pinus halepensis woods on peridotite is briefly diseussed.

The results of a floristic and vegetational investigation on the Aegean islet of Khrisi are pre- sented. Its vascular flora numbers 172 taxa (species, subspecics and hybrids), 92 of which are new records. A species new to science, Limonium chrisianum, is described and illustrated and two new combinations, Limonium roridum and Teucrium dumulosum, are proposed. Furthermore, an iconography of the fruited Bupleurum gaudianum, a rare endemic known up to now only from the islet of Gévdos is provided. The phytosociological analysis identifies 8 associations, that have been put in evidence by belonging to relevés of maquis, phrygana, salt marshes, psammophilous and rupicolous vegetation. The observed association, six of which are here described for the first time, are outlined from the floristic, ecological and chorological point of view. Besides, a new alliance, Cichorio-Limonion roridi, is proposed.

This paper deals with studies on the morphology and ecology of Delphinium cyphoplectrum Morphological observations carried out on several natural populations showed that in nature D. cyphoplectrum mainly oceurs on slightly calcareous soils with a basic pH and a sandy to sandyloamy texture. Pollens are tricolpate and spherical. In the light of the results obtained, it is clear that there is no need for dividing this species into varieties in Turkey.

A floristic and environmental (ecological) study on Sesleria caerulea (L.) Ardoino (syn. S. uliginosa Opiz). new finding for the Central Apennines, is reported. Some morphological and anatomical characteristics and the comparison among three related Sesleria species are also pointed out

A description is given of the plant life of the small hill of Sào Bartolomeu, Nazaré in W Portugal which, because of its steep terrain, retains some features of the country’s original vegetation. Lists are given of its vascular plants {c. 150, lichens (c. 68) and bryophytes (c. 17). Its phyto- geography with its elements of Mediterrancan, Euro-Siberian and Macaronesian phytochoria is discussed; the dominant one is Mediterrancan. A brief phytosociological survey is presented. Although most of its plants are not rare, the importance of Sào Bartolomeu’s hill as a compact portuguese refugium for a wide and interesting range of plant forms is emphasised, and the need for a formal protected status is stressed.

A study of the Marine benthic flora of the Gargano promontory has been performed, in order to know the benthic algal communities of this zone. A list of 213 taxa at specific and infraspecif- ic level has been obtained (153 Rhodophyceae, 30 Phaeophyceae and 30 Chiorophyceae). among which 115 of them are new for the Gargano coast and 12 are new for the Adriatic Sea The discovery of propagules-bearing thalli of Alsidium corallinum, of thalli of Antithamnion cruciatum with intercalary spores and of female gametophytic thalli (with gonimoblasts) of Corallophila cinnabarina can be numbered among the most interesting result of this study.

In the Mediterranean area and its surrounding floristic regions (Macaronesian, Circumborcal, Irano-Turanian, and Saharo-Arabian) the genus Teucrium L. (Labiatae) has around 242 taxa grouped in 9 sections according to Bentham (1832-1836) with the additions made by Boissicr (1879). Section Teucriopsis Benth. is endemic to the Canary and Madeira Islands. Section Teucrium comprises 28 perennial herbs and shrubs. Section Stachyobotrys (Benth.) Kastner is a section with 7 rare taxa, one of them endemic to Morocco and two to Turkey. Section Scorodonia (Hill) Schreb., includes 18 half-shrubs from open forests, 16 of them endemic to the western Mediterranean; the only one in the genus which shows a clear bilabiate calyx (excluding T. abutiloide L'Her. and T. betonicum L’Hér. from sect, Teucriopsis). Section Spinularia (Boiss.) Kistner comprises the only winter-deciduous 7 herbs of the genus. Section Isotriodon with 16 small half-shrubs is found only in crevices and cliffs and seems to_be of recent origin. Section Chamaedrys (Mill.) Schreb., is represented in all Mediterrancan lands, with 35 taxa they are mainly half-shrubs endemic to Turkey, Greece and SE Spain and perennial herbs with thizomes. Section Polium (Mill.) Schreb.. is a variable section in the leaves, calyx and indu- mentum, arranged in 4 subsections: (1) Subsection Polium including 64 gynodioccious half- shrubs and scrubs. 70% of them distributed in Spain and Morocco; (2) Subsection _Rotundifo...

his paper analyzes the Greek, Balkan, and Sub-Balkan endemic taxa present in the flora of Mount Vermion in order to define the phytogeographical connections between Mt. Vermion and other mountains and areas of Greece and the Balkan Peninsula. The chorological spectrum of the total flora, which consists of 1042 taxa, is also analyzed. Seven taxa are reported from Mt. Vermion for the first time. Compared to other mountains of the same geographical arca (NC), Mt Vermion appears t0 have closer phytogeographical links with Mts Olympus, Vourinos, Pieria, Voras, Vamous and Pinovo in decreasing order of floristic similarity. The analysis of Greek endemic taxa shows that Mt. Vermion has greater phytogeographical connections with Southern Greece. The impact of Balkan elements on Mt. Vermion is significant.

Tortula israelis is reportcd for the first time in Sicily from the Agrigentoo town. This finding is the second in Italy. The species . whose distribution is scattered in the Medilerranean, is known from Spain, ltaly. lsrael, Turkey and Cyprus.
