TAXONOMY, CHOROLOGY, ECOLOGY AND COENOLOGY OF THE ALCHEMILLA MONTICOLA SPECIES

For some polymorphic genera, such as Alchemilla (Fam. Rosaceae), widespread over large areas, it can be said that the taxonomy of species is difficult. Therefore, the aim was to know the Alchemilla species from the Romanian Carpathians in all aspects, in relation to the complex researches that are carried out from a taxonomic point of view at European level. The species Alchemilla monticola, presented in this paper, is thoroughly analyzed from the taxonomic, ecologic, chorologic, coenologic and even plantlet points of view. New additions have been made in respect of the chorology of this taxon in the Romanian Carpathians

TAXONOMIC, CHOROLOGIC AND COENO-ECOLOGIC FEATURES OF THE ALCHEMILLA COLORATA SPECIES

Monographic research on the Alchemilla genus has been motivated by its complexity. Alchemilla species are mountainous, subalpine and alpine plants, perennial, small to medium. Their identification is usually difficult. The aim was to find new characters and criteria for the most precise delimitation of the different microspecies. Apart from the delimitation and description of species of this genus and in addition to morphological criteria, other criteria are required, such as ecology, chorology, phytogeography, karyology etc. Alchemilla colorata, analyzed in this paper, is a microspecies that has separated itself from the aggregate species Alchemilla hybrida (L.) Mill. In addition to taxonomy information, ceno-ecological characteristics and new data on the chorology of this taxon in the Romanian Carpathians are presented.

DATA ON THE PRESENCE OF INVASIVE AND POTENTIALLY INVASIVE ALOGEN PLANTS IN OLT COUNTY (ROMANIA)

The research carried out in Olt County regarding invasive and potentially invasive alogen plant species is a necessary step in order to complete the information on their distribution at the national level. The data obtained will be able to be used for a careful monitoring of these plants and the adoption of the necessary management measures regarding the eradication or prevention of their introduction and spread. In this sense, an inventory of invasive and potentially invasive plant species identified on the territory of Olt county is presented, with information on the geographical origin, life form, biological form, an assessment of the degree of invasiveness, chorological data, habitat, as well as aspects related to the impact they exert on native vegetation, human health or the economy. The preliminary analysis of the list of invasive and potentially invasive alogen plants identified in Olt County highlights, in particular, the presence of some species of concern for the European Union (such as Ailanthus altissima, Asclepias syriaca and Elodea nuttallii). Besides these, the most widespread invasive species found in Olt county are Ambrosia artemisiifolia, Robinia pseudoacacia, Morus alba, Amorpha fruticosa, Acer negundo, Amaranthus retroflexus, Erigeron annuus, E. canadensis, Lycium barbarum, Sorghum halepense, Xanthium orientale subsp.italicum. It is well known that the impact of invasive species on the environment, the economy and in some situations even on human health is major and that is why these organisms must be subject to an extensive and continuous monitoring process. Also, in order to control the introduction and spread of invasive and potentially invasive species, a series of appropriate management measures are required

NEW CHOROLOGICAL DATA FROM OLTENIA (ROMANIA) FOR APHANES AUSTRALIS RYDB. AND MONTIA FONTANA L. SUBSP. CHONDROSPERMA (FENZL) WALTERSSPECIES

In this paper we present the new chorological information from Oltenia (floristic province of Romania) for species Aphanes australis (Rosaceae) and Montia fontana subsp. chondrosperma (Portulacaceae), accompanied by some considerations from ecological and cenological points of view

ORNAMENTAL PLANTS FROM THE COMMELINACEAE AND PIPERACEAE FAMILIES EXISTING IN THE GREENHOUSES OF THE BOTANICAL GARDEN "AL. BUIA" FROM CRAIOVA

Greenhouses of the Botanical Garden "Al. Buia" in Craiova house a varied collection of plants, belonging to numerous families. In this paper, species from the families Commelinaceae and Piperaceae are presented. The family Commelinaceae includes herbaceous plants, rarely lianas, native to tropical and temperate regions of the world, except Europe. In the greenhouse, this family is represented by ornamental species of the Callisia, Cyanotis and Tradescantia genera. The family Piperaceae comprises herbaceous plants, subshrubs or lianas, rarely trees, with simple, entire leaves, with stipules, often succulent and with small, bisexual or unisexual flowers, grouped in spikes or spadix. They are plants that grow spontaneously in tropical or subtropical areas around the world, but the greatest diversity is found in the Americas in a wide range of habitats being distributed from the southern United States of America to Chile and Argentina. In the greenhouses of the Botanical Garden this family is represented by two genera: Piper and Peperomia. In addition to the decorative effect, numerous representatives of the Piperaceae family are used as a food ingredient (Piper longum, Piper nigrum, Peperomiapellucida) and in traditional medicine to treat a wide variety of conditions: inflammatory diseases, gastrointestinal and respiratory tract disorders, acne, kidney diseases. Therefore, disseminating information about the existing ornamental plants in the greenhouses of the Botanic Gardens on the one hand supports their botanical value and on the other hand represents another step for environmental education

MEDICINAL PLANTS FROM GREENHOUSES COLLECTION "AL. BUIA" BOTANICAL GARDEN OF THE UNIVERSITY OF CRAIOVA (NOTE I)

In this paper are presented the medicinal plants from the greenhouses Botanical Garden "Al. Buia" of the University of Craiova. In the greenhouses collection there are exotic plants, well identified, obtained over time from seed or cuttings in the exchange of plant material between the Botanical Garden and other similar institutions in the country or abroad. Knowledge of all aspects of these exotic plants and disseminating information to both specialists and the general public is one of the objectives of University Botanical Gardens.The species with therapeutic potential existing in collection Botanical Garden greenhouses are known in particular as ornamentals and less from the point of view of their use as medicinal plants

MEDICINAL PLANTS FROM GREENHOUSES COLLECTION "AL. BUIA" BOTANICAL GARDEN (NOTE II)

In the paper are presented the medicinal plants from the greenhouses collection of Botanical Garden "Al. Buia” from the University of Craiova. The species existing in the collection are better known as ornamental plants than as medicinal plants. These taxa with ornamental and medical value were obtained largely through the exchange of plant material between the Botanical Garden and other similar institutions

THE LIST OF MAIN SPONTANEOUS MEDICINAL PLANTS FROM ROMANIA

The paper presents the list of spontaneous medicinal plants in Romania, for each taxon being indicated the scientific and vernacular name, the type of collection and plant organs collected. A special mention is made for medicinal plants in Romania that are included on the Red Lists. For these a series of recommendations are made regarding their collection from the spontaneous flora and special protection measures
