Pages 3-8

Full reference | Abstract | Full text PDF

ABSTRACT:  In water samples of salt marsh Slatina in 2006 we found Cylindrospermopsis raciborskii (Woloszinska) Seenayya et Subba Raju. h e i ndings of C. raciborskii are of particular importance given that this species produces cyanotoxins and that it may be considered as potentially invasive and harmful to waters in Serbia. h e present paper is concerned with both general and specii c characteristics of C. raciborskii and with specii c characteristics of the habitats in which the species was found considering its invasive and harmful potential.

Distribution of the genus Ephedra (Ephedraceae) in Calabria (S Italy)
CARUSO G, UZUNOV D, GANGALE C & PIGNOTTI L.
Pages 15-22

Full reference | Abstract | Full text PDF | Appendix

ABSTRACT:  A chorological study on the distribution of the genus Ephedra L. in Calabria was carried out. E. nebrodensis subsp. nebrodensis was already known to occur in Pollino Massif (N Calabria). Field investigations have been done to i nd other stands in Calabria without results. E. distachya subsp. distachya occurs mainly on the sandy coasts, especially Ionian, occasionally inwards along sandy river banks and rarely in rocky habitats. This species shows a fragmented distribution, has disappeared from some coastal areas and is regressing because of human activities. E. fragilis , recently excluded from regional flora because of some wrong past records, has been found with a small population by the Tyrrhenian coast in the S. Ferdinando surroundings. All studied species need conservation measures against existing threats, especially E. fragilis because of its small population size, persisting human pressure and lack of protection.

The phytogeography of European bryophytes
FRAHM J-P.
Pages 23-36

Full reference | Abstract | Full text PDF

ABSTRACT:  A survey is given of the origin and distribution patterns of European bryophytes. The mixture of floristic elements is explained by the vegetation history of the Holocene, during which different floristic elements invaded under different climates. In contrast to other higher plants, the ranges of bryophytes are much wider and transcontinental, and relicts from the Tertiary and the ice ages play a more important role.

Pages 41-48

Full reference | Abstract | Full text PDF

ABSTRACT:  Th e relationship between genetic similarity and larger geographical distance among populations of plant species has been attributed to a number of dif erent factors mostly breeding systems. We assessed this relationship among i ve accessions of seli ng legume Lathyrus sativus L. (grass peas, Fabaceae) using RAPDs by including 10 randomly selected individuals from each accession. Five primers produced 73 clear, reproducible and scorable polymorphic bands. The percentage polymorphic bands ranged from 20.6% in German to 60.3% in Polish accessions. The range of Nei’s within-accession genetic diversity was wide, ranging from 0.075 in German to 0.25 in Polish accessions. Partitioning of total genetic diversity by AMOVA indicated 76.44% genetic diversity among accessions and 23.56% within accessions, indicating that L. sativus is a seling species. The shortest genetic distance was detected between German and Iranian accessions (0.202), while the greatest genetic distance was revealed between Iranian and Polish accessions (0.5102), indicating that in seling species genetic similarity among accessions is not correlated with geographical distance.

Comparative study of seed germination and seed vigour test in Andrographis paniculata (Acanthaceae)
KUMARI A, LAL RK & SINGH KLB.
Pages 49-52

Full reference | Abstract | Full text PDF

ABSTRACT:  Kalmegh (Andrographis paniculata Nees.) is an important medicinal plant which is employed in the Indian traditional system of medicine (Folk medicine), Homeopathy, Ayurveda and Unani system of medicine. Its leaves, stem and inl orescence are used as medicine. Its major bitter principles are diterpenoids - andrographolide and neo-andrographolide. It is useful in the treatment of liver disorders, hepatitis, dysentery, febrifuge etc. h e herb kalmegh is also used as a liver tonic, in hyperdispsia, wounds, ulcers, chronic fever, malarial and intermittent fevers, inl ammations, coughs, bronchitis, skin diseases, leprosy, colic, l atulence, diarrhoea, dysentery, haemorrhoids. h is study of germination revealed that germination was essentially complete at er 16 d. KNO 3 and GA 3 improved the seed germination percentage. Germination in the presence of NaHClO 3 was rapid, taking only 8 d. Being a medicinal plant, KNO 3 and NaHClO 3 treatments are economic and easily applied by nursery workers and poor farmers in developing mass planting stocks.

KEY WORDS:  Andrographis paniculata, cancer therapeutic, diterpenoid compound, kalmegh, germination, seed vigour

Seasonal and spatial dynamics of Stratiotes aloides (Hydrocharitaceae) plants
EFREMOV AN & SVIRIDENKO BF.
Pages 59-52

Full reference | Abstract | Full text PDF

ABSTRACT:  A study of the peculiarities of the spatial dynamics of Stratiotes aloides L. plants in dif erent seasons is discussed. Th e mechanism of the immersion and buoyancy of S. aloides plant, established by phylogenetical factors, helps them to survive the unfavorable winter period in the water bodies of the temperate climatic zone of the North Eurasia. It was found that the mechanism of immersion in the fall and emergence in spring is based on several factors. The main contribution comes from seasonal variation of the structural “weight” of the leaves, while the seasonal dynamics of starch and mineral (ash) content is less important.

KEY WORDS:  Stratiotes aloides, seasonal spatial dynamics of specimens, structural “weight” of leaves, starch content,ash content

Retypification of two infraspecific names from Caryophyllaceae

ABSTRACT:  Heliosperma pusillum var. pancicii, was originally described in 2007. A typographic error occurred as part of the citation of the type, thus making useless its current usage. Therefore, a neotype from BEOU has been designated to avoid the conservation proposal. Silene sendtneri f. slavnicii was described in the same paper and its original type material was accidently destroyed in BEO. A corresponding specimen from BEOU has been designated as the lectotype.

Symphyotrichum novae-angliae (Compositae) new alien species in Serbia

ABSTRACT:  Symphyotrichum novae-angliae (Linnaeus) G. L. Nesom is native to almost every area in North America east of the Rocky Mountains, but excluding the far north of Canada as well as some of the southern States. Due to the attractive l owers, numerous cultivars of have been developed. Furthermore, as a result of its increased usage in the garden, it has been introduced to many area beyond its natural range. In many places Symphyotrichum novae-angliae is escaped from cultivation and naturalized as an alien species. According to Eu ro+Med PlantBase there is a presumption that the species is introduced in the countries of the Former Yugoslavia.
Based on our research in the i eld and the studies of herbarium material, we have found that S. novae-angliae is present in Serbia, both as cultivated ornamental plants, as well as a naturalized alien species.
We have registered this species on 25 localities that are situated in 18 UTM 10 km x 10 km squares. Twenty two of the localities refer to a small group of individuals which are cultivated, while the remaining 3 i ndings relate to plants that have escaped from cultivation and have naturalized as a alien species. Size estimation of naturalized population s and detailed chorological data (locations of occurrences recorded with GPS, and distribution map presented at UTM grid squares of c. 10 km × 10 km) are presented
