At first glance appearing like Lilium arboricola Stearn which is related to the L. primulinum group, but differing in the maroon-purple petals forming an open stellate-cam- panulate flower instead of the reflex- ed apple-green petals of L. arboricola. The flowers are superficially similar to those of L. souliei and L. taliense, Photographs: Bleddyn Wynn-Jones Photographs: but these species differ in many details, including a lack of axiliary bulbils.

    Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus.

This pattern is likely attributable to consanguineous Conservation mating, and this hypothesis is supported by a low relatedness coefficient. Our study Genetic diversity fl Gene flow suggested that environment factors might restrict gene ow among populations. In Microsatellite markers addition, physical distances between populations were not related to genetic distances, Ypsilandra thibetica implying that ancestral populations might have been distributed over a wider area. These results suggest that Y. thibetica should be a high priority for conservation managers.

China *For correspondence: [email protected] Abstract The whole plant of Ypsilandra thibetica Franch, a perennial herb, has the officinal functions in heat-clearing, detoxifying and relieving congeation. YB16, one of the steroidal saponin in Y. thibetic, exerts anticancer activity in prostate cancer and lung cancer. However, the bioactivity and underlying mechanisms of YB16 in colorectal carcinoma (CRC) are not understood. In the present study, by MTT, apoptosis, mitochondrial membrane potential levels and intercellular reactive oxygen species (ROS) assays, YB16 inhibited the proliferation of cells and induced apoptosis in CRC HCT116 and HCT8 cells. Meanwhile, YB16 provoked mitochondrial membrane potential depolarizing in a concentration-dependent manner. Further analysis showed that YB16 induced apoptosis via stimulating the production of intercellular ROS and the antioxidant NAC reversed the apoptosis in HCT116 and HCT8 after YB16 treatment. These datas demonstrated that YB16 induced

  • Genetic Diversity of Three European Veratrum Species Revealed by Amplified Fragment Length Polymorphism

Chemical and genetic characterization of Veratrum species deposited in European collections is important for genepool preservation and identification of populations with desired metabolic properties.Veratrum album, V. lobelianum and V. nigrum are native to Europe, and in Poland are ranked as rare or threatened. Genetic variation of European Veratrum species was characterized by Amplified Fragment Length Polymorphism (AFLP) markers. The accumulation of jervine as a represen- tative of steroidal alkaloids was measured in seeds. Distribution of 380 markers generated from eight primer combinations was useful for studying genetic relationships among and within species in the Veratrum genus and the most divergent populations were identified. Genetic variation between 12 populations ofVeratrum species supports the classification ofV. lobelianum as a subspecies of V. album. However, the results need further validation on extended material. A higher genetic diversity (22.3%) was observed between populations of V. nigrum as compared to V. album (14.5%). Contents of jervine allowed for discrimina- tion of the studied Veratrum species and can be used as a potential chemotaxonomic marker. The highest jervine levels were found in V. album. V. nigrum seeds had only trace amounts and no jervine was detected in seeds of V.

Email: [email protected] (Manuscript received 4 October 2016; accepted 28 March 2017; online published 3 May 2017) ABSTRACT: Two closely allied genera Chamaelirium Willd. and Chionographis Maxim. distributed disjunctively in eastern North America and eastern Asia are taxonomically reexamined, and a new classification is presented. Chionographis is included in Chamaelirium, and the latter comprises two sections Chamaelirium and Chionographis (Maxim.) N. Tanaka (comb. nov.). The former is monotypic (C. luteum), while the latter is subdivided into two subsections Chionographis and Cathayana N. Tanaka (subsect. nov.). The former subsection comprises four species indigenous to Japan and Korea, and the latter has four species native to Vietnam, Laos and China. A total of 14 new combinations at or below the rank of species (eight at specific, three at subspecific, and three at varietal rank) are circumscribed. Sect. Stenotepalon F. Maek. is reduced to a synonym of sect. Chionographis. Chamaelirium luteum Miq. f. gracilis Miq. is also reduced to a synonym of Chamaelirium japonicum (Willd.) N. Tanaka. Chamaelirium (s.l.) and its infrageneric taxa (two sections and two subsections) are regarded respectively as monophyletic on the basis of morphological and phenological data.

  • Phylogenetic Classification of Seed Plants of Taiwan
    Lin and Chung Bot Stud (2017) 58:52 DOI 10.1186/s40529-017-0206-6 ORIGINAL ARTICLE Open Access Phylogenetic Classifcation of Seed Plants of Taiwan Cheng‑Tao Lin1 and Kuo‑Fang Chung2* Abstract Background: Biological classifcation, the hierarchical arrangement of scientifc names of organisms, constitutes the core infrastructure of biological databases. For an efcient management of biological databases, adopting a stable and universal biological classifcation system is crucial. Currently in Taiwan Biodiversity Information Facility (TaiBIF; http://taibif.tw/), the national portal website that integrates Taiwan’s biodiversity information databases, angiosperms are arranged according to Cronquist’s System of Classifcation, which is not compatible with current trend of the Angiosperm Phylogeny Group (APG) classifcation. To consolidate the function and management of the database, TaiBIF is moving to adopt the APG IV classifcation and Christenhusz et al. (Phytotaxa 19:55–70, 2011)’s classifcation of gymnosperms, which we summarize as the Phylogenetic Classifcation of Seed Plants of Taiwan. Results: The Phylogenetic Classifcation of Seed Plants of Taiwan places gymnosperms in fve families [vs. eight families in the Flora of Taiwan (FOT)] and angiosperms in 210 families (vs. 193 families in FOT). Three FOT gymnosperm families are synonymized in current treatment. Of the 210 APG IV families, familial circumscriptions of 114 families are identical with FOT and 50 families are recircumscription of FOT, with 46 families newly added. Of the 29 FOT families not included in current classifcation, two families are excluded and 27 families are synonymized. Conclusions: The adoption of the Phylogenetic Classifcation of Seed Plants of Taiwan in TaiBIF will provide better service and efcient management of the nation’s biodiversity information databases.
