Novosti iz adventivne flore Slovenske Istre

V članku je predstavljenih nekaj novih nahajališč adventivnih vrst v Slovenski Istri. Najverjetneje prehodno pojavljanje na južni meji areala imajo vrste Dasypyrum villosum, Hedysarum coronarium in Piptatherum miliaceum s po enim novoodkritim nahajališčem, medtem ko so najverjetneje z vrtov ušle Iris foetidissima, Periploca graeca in Soleirolia soleirolii, prvi dve s po enim in slednja z več novimi nahajališči. Hedysarum coronarium in Periploca graeca sta bili prvič zabeleženi v flori SlovenijeArticle briefly discusses the occurrence of 6 adventitious species in the flora of Slovenian part of Istria. Dasypyrum villosum, Hedysarum coronarium and Piptatherum miliaceum are most probably recorded as casuals on the northern border of their native distribution range, each in one new locality. On the other hand, Iris foetidissima, Periploca graeca and Soleirolia soleirolii escaped from cultivation and established in one to more localities. Hedysarum coronarium and Periploca graeca were recorded for the first time in the flora of Sloveni

The genus Euphorbia in Slovenia

Članek obravnava rod mlečkov (Euphorbia) v Sloveniji. Na podlagi revizije dosegljivega herbarijskega materiala smo potrdili uspevanje 28 vrst mlečkov naozemlju Slovenije (od 36 vrst, ki jih navaja literatura), obravnavamo pa tudi dve novi vrsti za Slovenijo - Euphorbia taurinensis All. in E. myrsinitesL. Pregledu podatkov o razširjenosti posameznih vrst v Sloveniji in okoliških deželah sledijo ekološki in fenološki podatki. Zemljevidi razširjenosti temeljijo na konkretnih podatkih o pojavljanju vrst in predstavljajo izhodišče za naravovarstveno vrednotenje posameznih vrst. Izdelali smo ključ za določanje mlečkov, ki uspevajo v Sloveniji.The study presents the results of revision regarding the genus Euphorbia in Slovenia. On the basis of the revision of available herbarium material, the occurrence of 28 Euphorbia species was confirmed (out of 36 listed in different literature sources) and two new species were found - Euphorbia taurinensis All. and E. myrsinites L. The data on taxa distribution in Slovenia and its neighbouring countries, as well as their ecology and phenology were gathered. On the basis of literature, herbarium revision and field work, distribution maps of the studied species were produced. Suggestions for nature conservation and protection of some of them were also proposed. Furthermore, determination key for euphorbias growing in Slovenia was compiled

Epilobium obscurum Schreb., nova vrsta v flori SLovenije

During the revision of herbarium material (Herbarium LJU) of the genus Epilobium, a new species for the flora of Slovenia found. The specimen of Epilobium obscurum (short-fruited willowherb) had been collected in 1994 in Koroška (N Slovenia) region. Eventually, some additional localities of this species in the Pohorje Mts. and in the Štajerska (NE Slovenia) region were recorded. The present article deals with known distribution of the species in Slovenia and its most reliable distinguishing characters.Med nedavno revizijo herbarijskega materiala herbarija LJU je bila odkrita tudi pola z vrsto Epilobium obscurum, najdena na Koroškem. To je bil prvi podatek o pojavljanju te vrste v Sloveniji. V zadnjih letih smo odkrili še več nahajališč na območjuPohorja in Štajerske. V članku predstavljamo trenutno znano razširjenost vrste v Sloveniji in razlikovalne znake, po katerih E. obscurum ločimo od podobnih vrst vrbovcev
