This paper gives a new contribution to the investigation of macromycetes in Monlenegro. The first part deals with the papers so far published and with the authors' researches about fungi and their protection. In the second part, 9 taxa of fungi coming from 4 localities of Montenegro are presented, 6 of which are new for this country.

In northem Morocco is found a complex of three endemic allied taxa of Teucrium sect. Polium (Miller) Schreb.: Teucrium chloroslachyum Pau & Font Quer subsp. chloroslachyum, T. chloroslachyum subsp. melillense (Mairel comb. el slal. nov. et T. gypsophilum Emb. & Maire.

The nutlet anatomy of 19 Jordani an Salvia L. (Labiatae) was studied. Transverse sections were prepared using wax embedding and spurr medium techniques. Significant differences were observed between the species in coat thickness and mucilage production. Epicarp thickness was found to range from 5-75 um, the mesocarp 13-75 um thick and the endocarp 18- 125 um thick. Sclereids were the dominant feature of the endocarp; the following types were recognized: columnar (macrosclereids) with large or minute lumina, and osteosclereids with large and small lumina. The anatomical characteristics studied were found to be taxonomically useful and provided extra evidence for the separation and characterization of the species studied.

The history of the taxonomy and nomenclature or taxa previously assigned to Asteriscus Mill. (sensu lato) is outlined. While the taxonomy of the group is presently well understood, two clearly defined genera being recogni zed, the nomenc1ature is messy. It is demonstrated that the genus that carne recently to be known as "Asteriscus" must bear the name Pallenis Cass. , while Asteriscus replaces Nauplius Casso As a result some nomenclatural transfers, here effected in the frame of a synopsis of the inc1uded taxa, cannot unfortunately be avoided.

Cytinus clusii is reported for the first time from Bulgaria. Il was found on Cistus incanus in the northem Strandza Mt. Short phytogeographical notes on this species are given . A new locality of Cytinus clusii from north·eastem Greece is recorded.

The discovery of Centaurea diluta in the Abruzzo region (central Italy) is reported. This species is native to Spain and N.W. Africa and is naturalized or occurs as a casual in some countries of Europe (Great Britain, Germany and Switzerland). The species probably arrived in ltaly through grain imports from Spain.

Demirkoy Town and its surroundings are situated in the heart of Istranca (Yildiz) Mountains. Istranca mountains range from northwest to southeast of European Turkey occupying 3% of tolal area of Turkey. In Ihe present study, 500 plant taxa were identi ied out of 1400 pi anI spccimens .col!ected during a period of 3 years.

Some notes are presented on the taxonomy and distriblltion of A. peregrina L. This taxon , which had been united with A. tomentosa L., is a separate species with two distinct subspecies, subsp. peregrina and subsp. heracleotica. The earlier lectotype designation for A. peregrina is explained.

Two species of Vicia subgen. Cracea from the S. W. Mediterranean, V. durandii Boiss. and V. monardii Boiss. , are typified. The former name is referable to V. altissima Desf. and the other becomes the correct name for the species improperl y and presently known as 'V. durandii".

C. soleirolii Duby s.l. has been studied by means of biosystematic analysis of dried and living specimens, in natural enviroments and under eultivation. Two species endemic of Corsica have been recognized: C. sfenopefalum Grenier and C. soleirolii Duby. C. sfenoperalum is widespread over 750 m, on screes and dry grasslands. It presents two ploidy levels, diploid and tetraploid. The latter is the most widespread. A dwarf morphotype occurring in the highest sites of the distribution area, has been distinguished as C. sfenopefalum varo nanum Barberis & al. varo 110V. C. sfenopefalum seems to be related to C. utriense Barberis, an endemic species of Ligurian-Piedmontese Apennines. C. soleirolii is restricted to the sumrnit area, over 1800 m, of Mount Renoso, Mount d'Oro and Mount Rotondo. It is a diploid relic entity. A detailed description, a new iconography and information on nomenclature, ecology and distribution are provided for both taxa.

Thirteen taxa of mosses new to Serbia have been recorded. Seven species are from Hepaticae, and five spccies and one variety are from the Bryopsida. or these Porella baueri (Schiffn.) C. Jens. is regionally endangered and Ortotrichum stellatum Brid. is recorded as rare.

The diicovery of Pterygoneurum subsessile was made in a very xeric area of southem Sicily during a research project on terrestrial bryophytc communities. P. sulbsessile had been previously reported in Trentino-Alto Adige near the Austrian border. In addition new localities for Pterygoneurum ovatum (Hcdw.) Dix. are given. A description , illustration, ecology and distribution of P. subsessile is presenled.

Twenly - seven lichen species are reporled from the southem part of the Island of Elba, Italy. One species, Perrusaria monogona Nyl. is new lo Italy.

The occurrence of Riella notarisii in Sicily is reported. Some brief notes on its ecology, taxonomy, chorology are presented.

Ophrys holoserica sllbsp. apulica was until recently considcred endemic to southem haly, but during the last few years severaI finds have been reported from Greece. In the present paper, a comparison is made between plants from Rhodes and Monte Gargano in Italy. It is concluded that they are not conspecific and that O. holoserica subsp. apulica must stili be considered endemic to southern haly. The Rhodean taxon is considered identical with the recently described O. calypsus from Leipsoi and Naxos. However, the taxonomic validity of O. calypsus is questioned, and it is hypothesized that it should rather be regarded as cases of hybridization and probably introgression between O. holoserica subsp. holoserica and O. solopax subsp. heldreichii. A distance diagram of morphological Ophrys data from Rhodes and Crete, as well as phenological observations on the Rhodean specimens, support our hypothesis. Possible pre- and post-zygotic barriers between the supposed parental taxa are discussed. While Hirth & Spaeth (1994) recognized O. calypsus as a separate species, Delforge (1995) split the complex into O. heldreichii var. calypsus and O. heldreichii var. pseudoapulica. In contrast, we propose that O. calypslIs should be treated merely as a hybrid complex with no need to be recognized as one or more independent taxa.

On the base of the fìnding of new slations of Carex Rrioletii in Tuscany, our chorological, ecological and karyological knowledge of this rare pian t of the mediterranean-ponlic flora is brought up to date. In Tuscany there had been no data about this elusive species for almost a century, as a consequence of thc difficult accessibility of the growing sites of ihe populations, their small area, and of the anthropic alterations occurred in two of the three localities in which it was found in the pasl. The populations are all restricted to shady and mesic forest habitats of the meditemmean and submediterranean belt with a conservative power for species of the tethyan-tertiary flora. C. Rrioletii ha s 2n ~ 48 small-sized chromosomes, an uncommon number within the genus Carex. Although less rare than previously thought, this species could become vulnerable lo extinction because of its low adaptive capacity to changed ecological conditions and ex ansion inability connected probably to its reproductive biology and to the absence of vegetative spreading systems.

12 taxa of charophytes belonging to the genera Chara, Lamprothamnium, Nitella, Nitellopsis and Tolypella were found in 22 aquatic stands. Nitella giracilis and N. mucronata are recorded as new for Greece. The presence of 5 taxa in Greece is confirned. Comments are also given for the found taxa, ali having few previous records from Greece.

The finding of Serrotula lycopifolia (Vill.) A. Kern. on the Altopiano delle Rocche (Abruzzo) is reported.

The chronological data on Merendera sobolifera in Bulgaria are presented together with the current status of 8 localities, two of which are new for the country. Species ecology, biology and manner of spatial dispersal have been studied , as well as the population structure of 3 investigated populations. Phytocoenological characteristics of 4 communities have been assessed. Some comments are given on the historical migration and distributionion of the species. An evaluation on of the human influence on the Merendera sobolifera populations has been made.
