  • Gymnaconitum, a New Genus of Ranunculaceae Endemic to the Qinghai-Tibetan Plateau
    TAXON 62 (4) • August 2013: 713–722 Wang & al. • Gymnaconitum, a new genus of Ranunculaceae Gymnaconitum, a new genus of Ranunculaceae endemic to the Qinghai-Tibetan Plateau Wei Wang,1 Yang Liu,2 Sheng-Xiang Yu,1 Tian-Gang Gao1 & Zhi-Duan Chen1 1 State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, P.R. China 2 Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, Connecticut 06269-3043, U.S.A. Author for correspondence: Wei Wang, [email protected] Abstract The monophyly of traditional Aconitum remains unresolved, owing to the controversial systematic position and taxonomic treatment of the monotypic, Qinghai-Tibetan Plateau endemic A. subg. Gymnaconitum. In this study, we analyzed two datasets using maximum likelihood and Bayesian inference methods: (1) two markers (ITS, trnL-F) of 285 Delphinieae species, and (2) six markers (ITS, trnL-F, trnH-psbA, trnK-matK, trnS-trnG, rbcL) of 32 Delphinieae species. All our analyses show that traditional Aconitum is not monophyletic and that subgenus Gymnaconitum and a broadly defined Delphinium form a clade. The SOWH tests also reject the inclusion of subgenus Gymnaconitum in traditional Aconitum. Subgenus Gymnaconitum markedly differs from other species of Aconitum and other genera of tribe Delphinieae in many non-molecular characters. By integrating lines of evidence from molecular phylogeny, divergence times, morphology, and karyology, we raise the mono- typic A. subg. Gymnaconitum to generic status. Keywords Aconitum; Delphinieae; Gymnaconitum; monophyly; phylogeny; Qinghai-Tibetan Plateau; Ranunculaceae; SOWH test Supplementary Material The Electronic Supplement (Figs. S1–S8; Appendices S1, S2) and the alignment files are available in the Supplementary Data section of the online version of this article (http://www.ingentaconnect.com/content/iapt/tax).

Clematis wood has features typical of wood of vines and lianas: wide (earlywood) vessels, abundant axial parenchyma (earlywood, some species), high vessel density, low proportion of fibrous tissue in wood, wide rays composed of thin-walled cells, and abrupt origin of multiseriate rays. Superimposed on these features are expressions indicative of xeromorphy in the species of cold or dry areas: numerous narrow late­ wood vessels, presence of vasicentric tracheids, shorter vessel elements, and strongly marked growth rings. Wood of Xanthorhiza is like that of a (small) shrub. Wood of Delphinium, Helleborus, and Thalictrum is characteristic of herbs that become woodier: limited amounts of secondary xylem, par­ enchymatization of wood, partial conversion of ray areas to libriform fibers (partial raylessness).

  • Red List of Vascular Plants of the Czech Republic: 3Rd Edition

(2012): Red List of vascular plants of the Czech Republic: 3rd edition. – Preslia 84: 631–645. The knowledge of the flora of the Czech Republic has substantially improved since the second ver- sion of the national Red List was published, mainly due to large-scale field recording during the last decade and the resulting large national databases. In this paper, an updated Red List is presented and compared with the previous editions of 1979 and 2000. The complete updated Red List consists of 1720 taxa (listed in Electronic Appendix 1), accounting for more then a half (59.2%) of the native flora of the Czech Republic. Of the Red-Listed taxa, 156 (9.1% of the total number on the list) are in the A categories, which include taxa that have vanished from the flora or are not known to occur at present, 471 (27.4%) are classified as critically threatened, 357 (20.8%) as threatened and 356 (20.7%) as endangered. From 1979 to 2000 to 2012, there has been an increase in the total number of taxa included in the Red List (from 1190 to 1627 to 1720) and in most categories, mainly for the following reasons: (i) The continuing human pressure on many natural and semi-natural habitats is reflected in the increased vulnerability or level of threat to many vascular plants; some vulnerable species therefore became endangered, those endangered critically threatened, while species until recently not classified may be included in the Red List as vulnerable or even endangered.

The thesis may not be reproduced elsewhere without the permission of the Author. OPTIMISING THE SEED PRODUCTION CYCLE OF Delphinium elatum L. A thesis presented in partial fulfilment of the reg uirements for the Degree of Master of Science in Plant Biology at Massey University, Palmerston North Katharine Bedford 2005 ABSTRACT Delphinium elatum L. (Ranunculaceae) hybrids are developed by Dowdeswell's Delphiniums located at 692 Brunswick Road, Wanganui (www.delphinium.co.nz), who grow delphiniums for seed export. Development of new cultivars is important for commercial purposes, and requires development of high quality breeds. The main objectives of this study were to determine reasons for variable seed set and low germination in commercial D. elatum hybrids and determine optimal parameters for seed germination and storage. Seed set was investigated by examining pollen viability, carpel structure, and pollen tube growth in vitro and in vivo. Seed structure was determined by paraffin embedding and sectioning of seeds. Results investigating variable seed set were inconclusive. Seed set is limited by pollen viability and age. Pollen viability is low (below SO%) in most cultivars, and pollen tubes growth rate is variable between cultivars and individual pollen grains. Ovule development showed no abnonnalities. Germination-promoting treatments were used to improve germination in D. elatum. Stratification (S 0 C) and application of gibberellic acid both improved gennination in D. elatum cultivars. Chilling at S°C reduced germination time in all cultivars, and increased total germination in cv.

Of the vascular plants that occur in the study region, a total of 280 medicinal plant species belonging to 164 genera from 51 families are reported. Of these, we collected voucher specimen for 123 species between June and August in the years 2015 and 2016. The families Asteraceae (46 species), Fabaceae (37 species), and Ranunculaceae (37 species) were represented most in the study area, while Astragalus (21 species), Taraxacum (20 species), and Potentilla (17 species) were the most common genera found.

    LABORATORY FEEDING TESTS ON THE DEVELOPMENT OF GYPSY MOTH LARVAE WITH REFERENCE TO PLANT TAXA AND ALLELOCHEMICALS JEFFREY C. MILLER and PAUL E. HANSON DEPARTMENT OF ENTOMOLOGY, OREGON STATE UNIVERSITY, CORVALLIS, OREGON 97331 ABSTRACT The first through fifth instars of the gypsy moth were tested for development to adults on 326 species of dicotyledonous plants in laboratory feeding trials. Among accepted plants, differences in suitability were documented by measuring female pupal weights. The majority of accepted plants belong to the subclasses Dilleniidae, Hamamelidae, and Rosidae. Species of oak, maple, alder, madrone, eucalyptus, poplar, and sumac were highly suitable. Plants belonging to the Asteridae, Caryophyllidae, and Magnoliidae were mostly rejected. Foliage type, new or old, and instar influenced host plant suitability. Larvae of various instars were able to pupate after feeding on foliage of 147 plant species. Of these, 1.01 were accepted by first instars. Larvae from the first through fifth instar failed to molt on foliage of 151 species. Minor feeding occurred on 67 of these species. In general, larvae accepted new foliage on evergreen species more readily than old foliage. The results of these trials were combined with results from three previous studies to provide data on feeding responses of gypsy moth larvae on a total of 658 species, 286 genera, and 106 families of dicots. Allelochemic compositions of these plants were tabulated from available literature and compared with acceptance or rejection by gypsy moth. Plants accepted by gypsy moth generally contain tannins, but lack alkaloids, iridoid monoterpenes, sesquiterpenoids, diterpenoids, and glucosinolates. 2 PREFACE This research was funded through grants from USDA Forest Service cooperative agreement no.
