Shift of the western boundary of the distribution area of Micromeria cristata (Hampe) Griseb. and Steptorhamphus tuberosus (Jacq.) Grossh

During field investigations of Mt Rumija, two new taxa for the flora of Montenegro were recorded: Micromeria cristata (Hampe) Griseb. and Steptorhamphus tuberosus (Jacq.) Grossh. From the phytogeographic point of view these data indicate a change in the distribution area of both taxa, which have shifted to the west. Ashort over-view of the taxonomic treatment of both genera is given.

Abstract

The alien flora of Montenegro is enlarged by 5 new species: Coreopsis tinctoria, Ipomoea indica, Lupinus × regalis, Physalis angulata, and Solidago canadensis. All species are grown as ornamentals, and thus horticulture is considered the most possible pathway for their introduction. Nevertheless, in the case of Physalis angulata, the occurrence might have originated in the remains of picnic meals. In order to define the alien status of these species, monitoring is needed, and thus we propose including the species on the National List of Indicators in environmental protection. Special attention should be paid to the species with invasive potentials: Solidago canadensis, Ipomoea indica and Physalis angulata.

Abstract

In this short communication we report a new fern for Montenegro - Botrychium matricariifolium (Doll) A. Braun ex W.D.J. Koch, known as the chamomile grapefern. Up to now, the only Botrychium species in the flora of Montenegro was B. lunaria (L.) Sw., a typical species for montane to alpine grasslands and meadows. One individual of B. matricariifolium was found in a forest opening on the mountain Babji zub. B. matricariifolium was accompanied by numerous individuals of B. lunaria. These species are clearly distinguished by the lamina, which is in B. matricariifolium 2-pinnatifid, while in B. lunaria it is 1-pinnate with trapezoid to flabellate pinnae. Although chamonile grapefern has a large range of distribution, it is everywhere a rare species that has some kind of protection status in the most European countries. In order to define the protection status of the species in Montenegro, further investigation is needed.

Abstract

Cutandia maritima is a circum-Mediterranean species that inhabits sandy dunes along the coast line. It is fairly frequent on the western Adriatic coast but fairly rare and possibly even non-native in the east. In Croatia, it was discovered in 1990 in Crnika Bay on the island of Rab, which was considered until 2005 to be the only site on the eastern Adriatic coast from the Gulf of Trieste in the north to Corfu in the south. In 2009, the species was briefly reported for Velika plaža (Long Beach) in Ulcinj (Montenegro) but without details about the habitat type and synecology. The aim of this paper is thus to provide a deeper insight into the ecology and synecology of C. maritima in the eastern Adriatic part of the distribution area. On Velika plaža in Ulcinj, the species was found along the whole sea-inland gradient of sand dunes, in various types of vegetation: [1210] - annual vegetation of drift lines, [2110] - embryonic shifting dunes, [2120] - shifting dunes with Ammophila arenaria (white dunes), [2220] - dunes with Euphorbia terracina, [2130*] - fixed coastal dunes with herbaceous vegetation (grey dunes), and also [2190] - humid dune slacks.

Abstract

During field investigations on Long Ulcinj Beach, Montenegrin coast, three taxa new to Montenegrin flora were collected: Colchicum cupanii Guss. subsp. glossophyllum (Heldr.) Rouy, Datura innoxia Mill. and Eclipta prostrata (L.) L. The first species is native to Europe, while the others are alien. Colchicum cupanii subsp. glossophyllum is an endemic of the Balkan Peninsula, with a distribution formerly restricted to Greece and Albania, so this new record extends its distribution to the north-west. The distribution of Eclipta prostrata in the Balkans is also enlarged by this new record for Montenegro, in a westerly direction.

Abstract

- Sixty taxa (59 species and 1 variety) of lichenized fungi are reported from a chestnut grove in Livari. The majority of them (55 species and 1 variety) occurred on Castanea sativa. The recently described Xylographa soralifera is new to the Balkan Peninsula. The lichenicolous fungus Monodictys epilepraria growing on Lepraria rigidula is new to Montenegro. The lichen mycota is compared with similar localities in Italy and Switzerland. The species composition in Livari is most similar to the Montieri site in Tuscany.

Abstract

The pollen features of Chaerophyllum coloratum L., endemic to the Dinaric Alps, have been examined by both light microscopy and scanning electron microscopy in order to contribute to a better understanding of the taxonomic status of the species. Flower visitors have also been observed and analyzed with the aim of clarifying certain pollination aspects of the species including flower attractiveness especially to honeybees, and also in order to ascertain its contribution to the bee pasture. The pollen grains of C. coloratum are isopolar, radially symmetrical and medium sized. Polar axis (P) is 26.83±1.77 μm length, and equatorial diameter (E) is 9.17±0.57 μm length. P/E ratio amounts 2.90±0.10 indicating a perprolate shape. In an equatorial view, the grains are constricted in the equatorial region (bone-shaped), with obtuse polar caps. In polar view, they are triangular with obtuse angles and furrows in the sides of the triangle (interangular). The grains are tricolporate with three straight ectocolpi arranged regularly meridionally, of mean length 14.43±2.17 μm, each of which has one endopore. The characteristic internal thickenings around the protruding, clearly visible endopores (costae) in the constricted equatorial region are obvious in light microscopy. The ornamentation is psilate, irregularly rugulate (“cerebroid”), the exine surface is rather undulating. With regard to the observed flower visitors, the following pollination types occurred: melittophily, myophily, sapromyophily, cantharophily, and phalaenophily, and the most frequent pollinator was the honeybee.

Abstract

The Illyric–Balkan endemic species Moltkia petraea (Tratt.) Griseb. is very interesting as a potential horticultural and medicinal plant. The aim of this study was to investigate soil conditions of M. petraea habitats, the phenolic content in plant parts, and the influence of soil properties on the phenolic contents. The results were evaluated using Spearman rank order correlations. Analyzed soil samples contained very low to intermediate levels of physiologically active phosphorus, but were very rich in potash. Organic matter content of soil was high. Phenolic compound content was higher in leaves than in flowers or stems. The analyses showed that M. petraea possesses considerable quantities of phenolic compounds and has no specific demands for particular soil conditions. A negative correlation was found between soil phosphorus content and total phenols content in leaves and stems, and with the total phenolic acids content in flowers. Organic matter in soil also found to have a negative influence on total tannins content in stems. Among the tested geographical locations, the Mljet population showed a higher degree of separation from the remaining locations.
