Abstract: On a basis of morphological analyses of achenas, as well as the monopodial structure of the rhizome, there it is coming to the rhizome, there it is coming to the fore the fact that Sennikov has restored the genus Pietrosia. Unfortunately, all the previously nomenclatural combinations, including here also those made by Sennikov himself, are not accurately and it is necessary an improvement of it. In this paper, there are made also some comments over Pietrosia, as a particular genus.

Abstract: In this paper we are analysing the main coenotaxonic units mentioned in the specialized literature in order to clarify the phytosociological classification of the Quercetalia pubescentis order on the Moldavian territory.
We identified and described the following plant associations: Piptapthero virescentis – Quercetum dalechampii Chifu, Sârbu et Stefan 1998, Tilio tomentosae – Quercetum dalechampii Sârbu 1979, Aro orientalis – Quercetum pedunculiflorae ass. nova et Fraxino angustifoliae – Quercetum pedunculiflorae Chifu, Sârbu et Stefan 1998.

Abstract: Aquatic vegetation represents an important natural filter for the impurities charge of the Danube river water, constituting a barrier which hinds the polluants entrance in the Black Sea. It is important to mention that the conventional industrial installations, to obtain the treatment objectives of waste waters, use the same physical , chemical and biological principles as that which acts in a natural wet zone. The Isac – Uzlina aquatic complex (Danube Delta Biosphere Reserve) was studied and a number of 13 aquatic associations was identified. For every of these, the floristic structure, composition and specific features are also given out. 40 releves of aquatic vegetation from 40 points were used to characterize this aquatic complex.

Abstract: The hornbeam groves forming the Aro orientalis – Carpinetum (Dobrescu et Kovacs 1973) Täuber 1991-1992 association are analyzed both phytocoenologically and from the viewpoint of the biomass and aerial productivity of the arborescent layer it develops. This association achieve a density of 670 trees/ha, a biomass of 340967,47 kg/ha and a productivity of 10470 kg/ha/year.

Abstract: In this paper, the forest vegetation in the Tecuci Plain (Galati County) is presented. There have been identifyed nine vegetal associations, framed out in four Classes, five Orders, and seven Alliances of vegetation. Thus, the forest vegetation is installed along the rivers, on the sand dunes, or on the hills in that region. Every association, in this paper, is accompanied by: a diagnosis, a live form’s spectrum, a fitogeographical spectrum, and a phytosociological table. Also, there are cross-references to the most significantly papers, in relation to this vegetation of the Tecuci Plain.

Abstract: The paper presents two plant associations of the class Phragmiti-Magnocaricetea Klika in Klica et Novac 1941: the association Glycerietum plicatae Kluczinsky 1928 of order Nasturtio-Glyceritalia Pignatti 1953, alliance Glycerio-Sparganioni Br.-Bl. et Sissing in Boer 1942, and the association Carici-Menyanthetum Soó 1955 of order Magnocaricetalia Pignotti 1953, alliance Magnocaricion elatae (Balatova-Tulakova 1963) Oberd. et al. 1967. The tables of phytosociological relevees, chorology, the ecology and the characteristic and accessory species were presented, and the analysis of bioforms, floristic elements and ecological indices was carried out for each association.

Abstract: In Iassy, „A. Fatu” Botanical garden’s Greenhouse complex (20 buildings with a total area of 3800 sq.m) hosts a remarcable fund of exotic plants (2700 taxa), native especially in subtropical, tropical and ecuatorial areas, on every continent.
This paper presents some of the plant collections grown in this space. It comes out that, by number, diversity and value (scientific/decorative) of the taxa, many collections – azaleas and camelias, carnivorous plant, palm trees, bromelias, orchids, cicads, crotons, ficuses – have a unicum value in the country.

Abstract: The present paper presents a new group of plants, from the “Useful Plants” sub-section, less known for its immunostimulant proprieties, but which are used in the composition of some modern drugs (neutraceuticals).
Out of the total number of twenty-three species, belonging to fourteen families, two are trees, two are shrubs, seven are annual plants and twelve are perennial.
The medicinal and toxic plants are listed in the alphabetical order of their Latin names, along with the family, vegetal material, the harvesting time, the geographic distribution and the therapeutic activity.
The immunostimulant plants represent a valuable material for scientific researcher or the studying process because of its known origins.

Abstract: As the continuous demography registered during the last decades of the last century increases, the population on the Earth reached alarming levels due to the increasing needs of the population in continuous increase on the one hand and on the other hand, due to the human intervention in larger areas of the Earth. This continuously increased ominous anthropic influence, that attracts also the limitation of the planetary resources of all kinds, conducted during the last years to the unanimous recognition of the fact that the plants have the status of vital element within the world natural heritage, being a main element for maintaining the life on Earth and representing at the same time an essential resource for the future, for the planet existence (Convention on Biological Variety, 1992; The Declaration from Grand Canaria on World Program for Plants Preservation, 2000).
