Abstract: the author has analyzed the variability at 3 (three) plant species, namely: Silene supina Bieb., Alkanna tinctoria Tausch, Himantoglossum hircinum (L.) Spreng. After this analyze, there are two new subspecies, depicted here for the first time: Silene supina Bieb. subsp. longicarpa Ciocârlan subsp. nova and Alkanna tinctoria Tausch subsp. petrosa Ciocârlan subsp. nova. As concerning Himantoglossum, there is a mention that in the flora of Romania is growing H. hircinum subsp. caprinum (Bieb.) Sunderm., and not H. hircinum subsp. hircinum. In this paper, is showed that a synonymyzation of the species S. supina Bieb. with S. spergulifolia (Willd.) Bieb. is an error ! The same is the situation of the synonymy between Himantoglossum hircinum (L.) Spreng. and H. caprinum (Bieb.) Sundern.

Key words: variability - Silene supina - Alkanna tinctoria - Himantoglossum hircinum – Romania

Abstract: As a result of the researches carried out in 2003 in the river Suceava basin (the forests in the area of Patrauti), we identified phytocoenoses of the association Fraxino angustifoliae-Quercetum pedunculiflorae Chifu et al. 1998. An analysis of their structure and composition made evident the trees relatively even-aged character and various composition, all the layers (arborescent, shrubs, herbaceous) being well represented.
The spectre of the bioforms is numerically outshone by hemicryptophytes but dominated by the phanerophytes when it comes to the biomass. Phytogeographically, the European elements are definitely prevalent.
The valuev of the overground phytomass of the trees (obtained after surveys on spot) higlight the dominance of the biomass of the stems, followed by that of the branches.


Key words: even-aged, abundance-dominance, phanerophytes, hemicryptophites, Euroasian elements, overground phytomass.

Abstract: In the „Flora of Romania” Jasione jankae is presented as a synonym name at J. heldreichii Boiss. et Orph. After an analysis of some samples collected from the “locus classicus” (Mountain Trescovat, Banat), we are demonstrating that J. heldreichii and J. jankae are two separated plant species, point of view backed by Janka & Hayek.

Abstract: The paper represents a part of the research carried out in a five-year period (within my Ph.D. paper called: “The Flora and the Vegetation of the Lower Hydrographic Basin of the River Motru”, coordinated by Professor V. CIOCÂRLAN, Ph.D.). The material contains additional information for the diagnosis of the taxa: Agróstis canína L. subsp. canína, Círsium créticum (L.) D' Urv.; it suggests a new variety for the species Trifólium stríctum L. var. pubéscens Costache var. nova; the following species are noticed to be new for the region of Oltenia: Achilléa roseo-álba Ehrend., Cárex guestphálica (Boenn. ex Rchb.) Boenn. ex O. Lang (with taxonomic considerations), Galinsóga quadriradiáta Ruiz & Pav., Xánthium saccharátum Wallr.

Abstract: The study analyzes the Lathyro aurei – Fagetum (Dobrescu et Kovacs 1973) Chifu 1995 association both phytocoenologically and from the viewpoint of the aerial phytomass of the arborescent layer and herbaceous layer it develops. The forests gathered in this association achieve a density of 548 trees/ha, a phytomass of the arborescent layer of 308639.24 Kg/ha and the herbaceous layer of 82.30 kg desiccated substance/ha.

Abstract: The autor is presenting here 43 rare plant species in the flora of Romania, discovered in various new localities. Most of them have been identyfied in Dobrudja, being included on different red lists (2, 5, 10). In order ot make a distinction among those 3 (three) red lists, concerning their degree of threatening, I have inserted the IUCN indices for every registred plant species here. One can remark a large difference between these red lists, which requires o good collaboration between botanists, to achieve a unitary red list for Romania.

Abstract: The presence of a new plant species is signaled out here, for the 1st time in Romania, by the authors of this paper. This plant – Eriochloa villosa (Thunb.) Kunth – is an invader one in the flora of Romania. It has been discovered inside the crops of flax, clover, sun flower, maize, at Livada, Satu Mare county. This species is a characteristic one for the rice crops, but it is growing also inside the wet meadows, along the river’s meadows.

Abstract: In this paper, the results of the field-researches made between 2004-2005 in different places of Bistrita Mountains are presented. The lichen flora analysis had carried out to 115 taxa identification, belonging to Ascomycotina Class. The species have been analysed from the ecological point of view, on the values of ecological indexes (light, humidity, temperature and chemical reaction of the substrata) published by Ellemberg et al (1992). 93,05% of the total number of species are common species and 6,95% are rare species (Cladonia amaurocraea, C. rangiformis, C. sulphurina, Cetraria sepincola, Pheophyscia ciliata, Peltigera pretextata). One species – Collema subflaccidum is for the second time cited in romanian lichenological flora.
