Marks, F.R. Wesley, & S. Gardescu. For a link to the Journal's 2008 issues and abstracts, go to: <http://www.torreybotanical.org/journal.html> The following list of vascular plants includes native and non-native species that occur in a multi-county area in central New York State (see map below). We have called this the "Cayuga Region," as it includes the "Cayuga Quadrangle" of the flora of Clausen (1949) and the "Cayuga Lake Basin" of earlier floras (Dudley 1886, Wiegand & Eames 1926). A single set of modern species concepts was used, to correct for variations in nomenclature among the floras. Species found only under cultivation are not included. SPECIES NAMES are in alphabetical order, within major group. NATIVE/NOT is with respect to the Cayuga Region. For non-natives, WHEN HERE is the year by which the species had first established i the region, based on the floras of Dudley (1886), Wiegand & Eames (1926), Clausen (1949), and Wesley (2005; unpublished). -

The seeds were collected mainly in Tibet, Pamir, Alai, Tien Shan, Yunnan, Kamchatka, Sechuan, Kunlun, Karakoram, Sakhalin, Patagonia, Turkey and others. Selected pictures are in my photogallery http://holubec.wbs.cz/ . There is a lot of items that were regenerated in the garden. They are as valuable as the natural collections and can be collected exactly when become ripe. These species proved to be growable in rock gardens in Central Europe. Those items are clearly marked with ex. Some items come from other collectors: Jiri Papousek (JP), Zdenek Obrdlik (ZO) and Jaro Horacek (JH). The plants were determined according to Floras, in case of the recent collections Fl. China, Fl Tajikistan, Fl Kyrgyzstan, Key to the vascular plants of Kamchatka. Some plants were not seen in flowers and therefore it is not possible to guarantee all determination. From previous expeditions there are still available many good items. All seeds are marked with a collecting year. Older ones were stored in refrigerator and they keep a good germination ability (some of them germinate even better the second year). Several abbreviations were used in descriptions: pl- plant, lv, lvs-leaves, fl, fls-flowers, infl-inflorescence. Please, order by both numbers and names to avoid mistakes. Seeds from another locality will be sent when the ordered item is gone. -

Severe Grazing Pressure on an Unpalatable Plant, Primula Japonica, and Its Potential Chemical Compound for Grazing Defence in a Long- Term Deer Grazing Habitat
Vegetation Science 37 : 101-107, 2020 Deer grazing on a plant with chemical defence 101 Short communication Severe grazing pressure on an unpalatable plant, Primula japonica, and its potential chemical compound for grazing defence in a long- term deer grazing habitat Ryo O. SUZUKI1*, Yuri MAESAKO2 and 1Faculty of Science, University of the Ryukyus 2Graduate School of Human Environment, Osaka Sangyo University 3 Shigeru MATSUYAMA 3Graduate School of Life and Environmental Sciences, University of Tsukuba We monitored the deer grazing pressure on a population of an unpalatable perennial, Primula japonica in a long-term grazed habitat by sika deer, using an enclosure treatment with cages for two years. The two-year census showed that all unenclosed individuals of this species lost their aboveground parts due to grazing, where- as all enclosed individuals survived and most of them elongated inflorescences at the end of the census period. Although inflorescences extended outside cages, no grazing on the reproductive organs was observed. We also quantified the main chemical compound of the species using the gas chromatography and evaluated variations in the concentration of the compound among regions (a high deer-density site and a low deer-density site) and among organs (leaves and inflorescences), which identified flavone as the main compound and detected a higher flavone concentration in flowers than in leaves but little difference among regions. Although the results showed a possibility that flavone can contribute to protecting reproductive organs from deer grazing, we could not demonstrate clear evidence that flavone has toxic effects on deer. Future studies need to evaluate whether deer also graze other unpalatable plants in high-deer density regions and to verify mechanisms on how sika deer can overcome the chemical defence of unpalatable plants. -

Prof. Dr. Karin Valant-Vetschera Acknowledgements It is my great pleasure to thank all those who, with their help and support, have contributed to the completion of this thesis. First and foremost I would like to express my sincere and heartfelt gratitute to my supervisor Assoc. Prof. Dr. Karin Valant‐Vetschera for giving me the opportunity to join the “Chemodiversity Group”. I thank her for assuming the dual role of supervisor and mentor. During the years of my diploma and doctoral theses she has continuously offered me the best guidance, support and advice I could have asked for. I am very grateful to Dr. Lothar Brecker for the characterization and identification of the isolated compounds. Additionally, I thank him for his constant encouragement, support and valuable suggestions. In the lab I have always received invaluable technical support from Mag. Johann Schinnerl, for which I extend him my earnest thanks and appreciation. Prof. Dr. Harald Greger has been very kind and supportive throughout the years, which I gratefully appreciate. Thanks are also due to Prof. Dr. Irene Lichtscheidl and Dr. Wolfram Adlassnig for providing access to their laboratory equipment and for their excellent guidance. I am deeply indebted to Prof. Eckhard Wollenweber (Institut für Botanik der TU Darmstadt, Germany) for the constant supply of authentic flavonoid samples, which made my lab life a lot easier. -
