As a result of collecting and analyzing a material from the Căpătânii Mountains, Beleoaia Peack, material belonging to the Euphrasia genus, we have noticed that it corresponds to a taxon which even now is placed under question in Romania's flora. The analysis of our material according to recent literature has led to the conclusion that the species is part of the E. stricta group, which is recognized by the usually rigid and erect stem and branches. Leaves glabrous to densely hairy, frequently also with short glandular hairs, usually narrowly ovate or elliptical to oblong-lanceolate; floral leaves usually appressed to the flower, with long, very acute to aristate teeth, the basal teeth apically directed. Capsule usually much shorter than calyx, oblong to elliptic-oblong. Within this group, in the 3rd volume of Flora Europaea, 4 species are included: Euphrasia stricta D. Wolff ex J. F. Lehm. (E. brevipila Burnat et Gremli, E. condensata Jordan, E. tatarica auct., non Fischer ex Sprengel), E. hyperborea Joerg., E. pectinata Ten. (E. tatarica Fischer ex Sprengel) and E. liburnica Wettst. From this whole group, in our country's flora are treated only two species: Euphrasia stricta D. Wolff ex J. F. Lehm. Which includes the subspecies pectinata (Ten.) P. Fourn (E. tatarica Fischer ex Sprengel) and the subspecies brevipila (Burnat et Gremli) Ciocârlan and E. liburnica Wettst. (with a question mark). Among the taxons of the material we collected, it corresponded to Euphrasia liburnica Wettst., thus clarifying the question marks from various works regarding the presence of this taxon in our flora. When determining the taxon we used material we collected ourselves from the above-mentioned research area, which we analyzed according to recent specialized literature. It is recognized by the following characters: 15-25 cm stem, purple leaves, glabrous or with hairs, not glossy when faded; the superior ones and the bracts ± ovate, length maximum two times greater then the width, with close-together dents. The corolla has a length of 4,5- 6,5 mm, and is lilac- coloured. The first flower appears at nodes 5-8. The capsule presents frequent and long ciliums on the edges, shorter or equal to the calyx. The proportion between the length and the width of the capsule is above 2. REFERENCES 1. Ciocârlan V. (2000). The Romanian ilustrated Flora. (in Romanian). Pteridophyta et Spermatophyta. 1038 pag.

(Orobanchaceae) in Iran Shahryar Saeidi Mehrvarz, Sayad Roohi, Iraj Mehrgan & Elham Roudi Summary: Comparative morphological, anatomical and palynological studies on six species Euphrasia L. (Orobanchaceae) in Iran are presented using plants collected from their type localities and many other populations. Euphrasia petiolaris and E. sevanensis are reported for the flora of Iran for the first time. In terms of anatomy, the phloem/xylem proportion in vascular bundles of stem and root, presence or absence of collenchyma at the periphery of stem cortex, the number of parenchyma cell layers of stem cortex and the thickness of the vascular bundle in the leaf midrib provide valuable characters in distinguishing species. According to the obtained results, the pollen morphology seems also to be taxonomically valuable. The main shapes observed among investigated taxa were spheroidal, oblate- spheroidal and prolate-spheroidal. The pollen grains were tricolpate and microrugulate, micropilate and microgemmate on exine surface. The relationships between taxa were estimated by analyzing the scored morphological, anatomical and palynological data using the Euclidian distance coefficient and UPGMA clustering method. Keys are provided for identification of the species of Euphrasia in Iran based on both morphological and anatomical features. Keywords: anatomy, palynology, Euphrasia, Orobanchaceae, taxonomy, flora of Iran The genus Euphrasia comprises about 450 perennial and annual green hemiparasitic species (Mabberley 2008). The distribution area ranges from Europe to Asia, the northern parts of America, South America, the mountains of Indonesia, Australia and New Zealand (Barker 1982).

Phylogenetic Biogeography of Euphrasia Section Malesianae (Orobanchaceae) in Taiwan and Malesia
Blumea 54, 2009: 242–247 www.ingentaconnect.com/content/nhn/blumea RESEARCH ARTICLE doi:10.3767/000651909X476229 Phylogenetic biogeography of Euphrasia section Malesianae (Orobanchaceae) in Taiwan and Malesia M.-J. Wu1, T.-C. Huang2, S.-F. Huang3 Key words Abstract Species of Euphrasia are distributed in both hemispheres with a series of connecting localities on the mountain peaks of Taiwan and the Malesian region including Luzon, Borneo, Sulawesi, Seram and New Guinea. biogeography Two hypotheses are proposed to explain this distribution pattern. The Northern Hemisphere might have been the Euphrasia centre of origin or the Southern Hemisphere. This study aims to reconstruct the core phylogeny of Euphrasia in the phylogeny connecting areas and tries to identify the migratory direction of Euphrasia in Taiwan and Malesia. The phylogeny rps2 gene sequence of Euphrasia, including sections Euphrasia, Malesianae and Pauciflorae, is reconstructed with the chloroplast trnL intron sequence molecular markers rps2 gene, trnL intron and trnL-trnF intergenic spacer. The results suggest that the migratory trnL-trnF intergenic spacer sequence direction between Taiwan and the Philippines is possibly from the north to the south. However, the migratory direc- tion within section Malesianae and the centre of origin of Euphrasia remain unanswered from our data. More data is needed to clarify this issue. Published on 30 October 2009 INTRODUCTION as the centre of origin (Von Wettstein 1896, Van Steenis 1962, Barker 1982), while the other theory considers it to be in the Euphrasia contains about 170 species and 14 sections, each Northern Hemisphere (Raven & Axelrod 1972, Raven 1973). with a typical distributional area (Table 1; Barker 1982: f.

Euphrasia Officinalis
The European Agency for the Evaluation of Medicinal Products Veterinary Medicines Evaluation Unit EMEA/MRL/667/99-FINAL August 1999 COMMITTEE FOR VETERINARY MEDICINAL PRODUCTS EUPHRASIA OFFICINALIS SUMMARY REPORT 1. Euphrasia officinalis (synonym: eyebright) is an aggregate of several Euphrasia subspecies, which are plants of the family Scrophulariaceae. Euphrasia is a frequent hemiparasite in grassland populations in North and Middle Eurasia, growing either unattached or attached to various host plants. The homeopathic mother tincture is prepared by ethanolic extraction of the entire flowering plant according to homeopathic pharmacopoeias. Significant constituents of Euphrasia officinalis are iridoid glycosides. Aucubin, catapol, euphroside, eurostoside (10-p-cumaroylaucubin, 0.04%), geniposide, 7,8-dihydrogeniposid (adoxosid), ixoroside and mussaenoside in the dried herb of Euphrasia rostkoviana have been identified. Aucubin and ixoroside are found in Euphrasia stricta. The content of aucubin in the dried total plant of Euphrasia stricta was 0.94%. In above-ground parts of Euphrasia rostkoviana phenolic acids were found, such as caffeic acid (102 mg/kg), ferulic acid (traces), vanillic acid (6 mg/kg) and, following acid hydrolysis, chlorogenic acid (18.5 mg/kg), gallic acid (10.5 mg/kg), gentisinic acid, p-hydroxy phenylpyruvic acid, protocatechuic acid (together with gentisinic acid 48 mg/kg). Further constituents were phenylpropanoid glycosides, such as leucosecptoside A in herbs of Euphrasia rostkoviana, lignans (dehydro-coniferyl alcohol 4b- glycoside, 0.013% of the dry total plant) and mannit in the herbal parts. Additional constituents of Euphrasia are tertiary alkaloids, phytosterols (b-sitosterol, stigmasterol), flavones such as apigenin, chrysoeriol and luteolin, and galactosides as well as flavonolglycosides like quercetin- 3-glycoside, quercetin-3-rutinoside and kaempferol-3-rutinoside.

Cies of Euphrasia (Orobanchaceae) and Its Consequences for Botanical Research on Protected Areas
Research eco.mont – Volume 9, Number 2, July 2017 16 ISSN 2073-106X print version – ISSN 2073-1558 online version: http://epub.oeaw.ac.at/eco.mont https://dx.doi.org/10.1553/eco.mont-9-2s16 Euphrasia’s hide-and-seek: periodicity of occurrence in some high-mountain spe- cies of Euphrasia (Orobanchaceae) and its consequences for botanical research on protected areas Ewa Posz Keywords: Euphrasia, periodicity, protected areas, botanical research Abstract The paper presents the results of long-term observations made on selected populations of two high-mountain Euphra- sia species. The monitoring was conducted during 2002–2016 in ranges of the Polish parts of the Carpathians and Sudetes. Field studies revealed periodical occurrence and disappearance of populations in the localities for one or more seasons, which may be connected with the life cycle of annual plants. The phenomena of periodicity occurrence and seed dormancy and their consequences are discussed. Introduction The genus Euphrasia (eyebright) is represented by ca. 350 species worldwide (Fischer 2004). High-moun- tain eyebright species occur at altitudes up to 4 450 m a.s.l. in the Himalayas (Li 1953). In Europe, eyebright species have been found in almost all mountain ranges at altitudes as high as 2 700 m a.s.l. (in the Alps) (Yeo 1978). There are 11 species of eyebright in Poland (Posz 2014, 2016), three of which, E. minima Jacq., E. picta Wimm. and E. corcontica (Smejkal) Smejkal et % are typical for siliceous bedrock. The range of E. salis- burgensis Funck is also limited to mountain areas, but it prefers calcareous bedrock.

Email: [email protected] Abstract The research presented in this paper had the purpose of Key words inventory and knowledge of spontaneous and subspontaneous plant species of Botanical Garden "Vasile Fati" Jibou, Salaj, Romania. Following systematic Jibou Botanical Garden, investigations undertaken in the botanical garden a large number of spontaneous flora, spontaneous taxons were found from the Romanian flora (650 species of adventive and vascular plants and 20 species of moss). Also were inventoried 38 species of subspontaneous plants, adventive plants, permanently established in Romania and 176 vascular plant floristic analysis, Romania species that have migrated from culture and multiply by themselves throughout the garden. In the garden greenhouses were found 183 subspontaneous species and weeds, both from the Romanian flora as well as tropical plants introduced by accident. Thus the total number of wild species rises to 1055, a large number compared to the occupied area. Some rare spontaneous plants and endemic to the Romanian flora (Galium abaujense, Cephalaria radiata, Crocus banaticus) were found. Cultivated species that once migrated from culture, accommodated to environmental conditions and conquered new territories; standing out is the Cyrtomium falcatum fern, once escaped from the greenhouses it continues to develop on their outer walls. Jibou Botanical Garden is the second largest exotic species can adapt and breed further without any botanical garden in Romania, after "Anastasie Fătu" care [11].

Mack. in South-Eastern Carpathians Mihai PUŞCAŞ Alexandru Borza Botanical Garden, Babeş-Bolyai University, 400015 Cluj-Napoca, Romania; [email protected] Abstract This study proposes a critical analysis of the distribution and habitat requirements of the rare arctic-alpine plant species Kobresia simpliciuscula (Wahlenb.) Mack. in the South-Eastern Carpathians. The species was recorded in this part of Carpathians only from Romania, in Bucegi Mountains. The mention of K. simpliciuscula in Rodna Mountains (Eastern Carpathians) is considered to be erroneous. K. simpliciuscula was found in the Southern Carpathians in a different habitat type compared to the one characteristic for populations in the Arctic and the Alps. The species does not grow in the pioneer phytocoenoses of the Caricion bicoloris-atrofuscae alliance but, on the contrary, in dry calciphilous alpine vegetation included in Oxytropido-Elynion. The plant communities where K. simpliciuscula was found in Bucegi Mountains belong to Achilleo schurii-Dryadetum (Beldie 1967) Coldea 1984. These phytocoenoses are very similar to those described for the species in Belianske Tatra Mountains (Western Carpathians, Slovakia). Keywords: alpine habitats, chorology, Cyperaceae, rare species, Romanian Flora Introduction cula, one of the rarest plant species in the Carpathian Flora (Čeřovský et al., 1999; Dihoru and Negrean, 2009).
