Also, the paper provides information about the hayfields floral richness, a great scientific value for Romania and Europe. The study of the flora was carried out in several stages: 2005-2008, 2013, 2017-2018. In the studied area, 397 taxa were identified, distributed in 82 families with therapeutic potential, represented by 164 medical taxa, 37 of them being in the European Pharmacopoeia 8.5. The study reveals that most plants contain: volatile oils (13.41%), tannins (12.19%), flavonoids (9.75%), mucilages (8.53%) etc. This plants can be used in the treatment of various human disorders: disorders of the digestive system, respiratory system, skin disorders, muscular and skeletal systems, genitourinary system, in gynaecological disorders, cardiovascular, and central nervous sistem disorders. In the study plants protected by law at European and national level were identified: Echium maculatum, Cephalaria radiata, Crambe tataria, Narcissus poeticus ssp. radiiflorus, Salvia nutans, Iris aphylla, Orchis morio, Orchis tridentata, Adonis vernalis, Dictamnus albus, Hammarbya paludosa etc. Keywords: Fărăgău, medicinal plants, human disease, Mureş County 1.

    Outline of Angiosperm Phylogeny

    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

Zeltnera beyrichii (Torr. & A. Gray) Mans., an insufficiently acknowledged North American medicinal plant species, may be considered a pharmacological substitute for commercial C. erythraea Rafn, since it accumulates in aerial parts nearly the same amount of secoiridoid glycosides: swertiamarin, gentiopicrin, and sweroside (13.76, 7.56, and 0.17 mmol per 100 g dry weight, respectively) in plants grown under greenhouse condition, and a considerable amount of xanthones: decussatin and eustomin. Additionally, Z. beyrichii produced as much biomass during cultivation in RITA® temporary immersion bioreactors as greenhouse-grown plants, in a third of the time. Plants grown in bioreactors contained moderate levels of total phenolics and total flavonoids, and possessed modest antioxidant activity and antimicrobial potential against eight bacterial and eight fungal species. Therefore, this species may be highly recommended for cultivation either in natural environment, or in bioreactors under in vitro conditions, for producing compounds of interest of modern pharmacology and food industry. Keywords: Zelnera beyrichii; temporary immersion bioreactors; secoiridoid glycosides; xanthones; antioxidant activity; antimicrobial activity.

    Phylogeny and Phylogenetic Taxonomy of Dipsacales, with Special Reference to Sinadoxa and Tetradoxa (Adoxaceae)

    PHYLOGENY AND PHYLOGENETIC TAXONOMY OF DIPSACALES, WITH SPECIAL REFERENCE TO SINADOXA AND TETRADOXA (ADOXACEAE) MICHAEL J. DONOGHUE,1 TORSTEN ERIKSSON,2 PATRICK A. REEVES,3 AND RICHARD G. OLMSTEAD 3 Abstract. To further clarify phylogenetic relationships within Dipsacales,we analyzed new and previously pub- lished rbcL sequences, alone and in combination with morphological data. We also examined relationships within Adoxaceae using rbcL and nuclear ribosomal internal transcribed spacer (ITS) sequences. We conclude from these analyses that Dipsacales comprise two major lineages:Adoxaceae and Caprifoliaceae (sensu Judd et al.,1994), which both contain elements of traditional Caprifoliaceae.Within Adoxaceae, the following relation- ships are strongly supported: (Viburnum (Sambucus (Sinadoxa (Tetradoxa, Adoxa)))). Combined analyses of C ap ri foliaceae yield the fo l l ow i n g : ( C ap ri folieae (Diervilleae (Linnaeeae (Morinaceae (Dipsacaceae (Triplostegia,Valerianaceae)))))). On the basis of these results we provide phylogenetic definitions for the names of several major clades. Within Adoxaceae, Adoxina refers to the clade including Sinadoxa, Tetradoxa, and Adoxa.This lineage is marked by herbaceous habit, reduction in the number of perianth parts,nectaries of mul- ticellular hairs on the perianth,and bifid stamens. The clade including Morinaceae,Valerianaceae, Triplostegia, and Dipsacaceae is here named Valerina. Probable synapomorphies include herbaceousness,presence of an epi- calyx (lost or modified in Valerianaceae), reduced endosperm,and distinctive chemistry, including production of monoterpenoids. The clade containing Valerina plus Linnaeeae we name Linnina. This lineage is distinguished by reduction to four (or fewer) stamens, by abortion of two of the three carpels,and possibly by supernumerary inflorescences bracts. Keywords: Adoxaceae, Caprifoliaceae, Dipsacales, ITS, morphological characters, phylogeny, phylogenetic taxonomy, phylogenetic nomenclature, rbcL, Sinadoxa, Tetradoxa.
