Flora of China 6: 1–113. 2001. CARYOPHYLLACEAE 石竹科 shi zhu ke Lu Dequan (鲁德全)1, Wu Zhengyi (吴征镒 Wu Cheng-yih)2, Zhou Lihua (周丽华)2, Chen Shilong (陈世龙)3; Michael G. Gilbert4, Magnus Lidén5, John McNeill6, John K. Morton7, Bengt Oxelman8, Richard K. Rabeler9, Mats Thulin8, Nicholas J. Turland10, Warren L. Wagner11 Herbs annual or perennial, rarely subshrubs or shrubs. Stems and branches usually swollen at nodes. Leaves opposite, decussate, rarely alternate or verticillate, simple, entire, usually connate at base; stipules scarious, bristly, or often absent. Inflorescence of cymes or cymose panicles, rarely flowers solitary or few in racemes, capitula, pseudoverticillasters, or umbels. Flowers actinomorphic, bisexual, rarely unisexual, occasionally cleistogamous. Sepals (4 or)5, free, imbricate, or connate into a tube, leaflike or scarious, persistent, sometimes bracteate below calyx. Petals (4 or)5, rarely absent, free, often comprising claw and limb; limb entire or split, usually with coronal scales at juncture of claw and limb. Stamens (2–)5–10, in 1 or 2 series. Pistil 1; carpels 2–5, united into a compound ovary. Ovary superior, 1-loculed or basally imperfectly 2–5-loculed. Gynophore present or absent. Placentation free, central, rarely basal; ovules (1 or) few or numerous, campylotropous. Styles (1 or)2–5, sometimes united at base. Fruit usually a capsule, with pericarp crustaceous, scarious, or papery, dehiscing by teeth or valves 1 or 2 × as many as styles, rarely berrylike with irregular dehiscence or an achene. Seeds 1 to numerous, reniform, ovoid, or rarely dorsiventrally compressed, abaxially grooved, blunt, or sharply pointed, rarely fimbriate-pectinate; testa granular, striate or tuberculate, rarely smooth or spongy; embryo strongly curved and surrounding perisperm or straight but eccentric; perisperm mealy. Between 75 and 80 genera and ca. 2000 species: widespread but mainly of temperate or warm-temperate occurrence in the N hemisphere, with principal centers of distribution in the Mediterranean region and W Asia to W China and the Himalayas, fewer species in Africa S of the Sahara, America, and Oceania; 30 genera (two endemic) and 390 species (193 endemic) in China. Arenaria, Silene, and Stellaria contain over half the species in the family in China. They are mostly concentrated in the Qinghai-Xizang plateau, and are especially rich from the Hengduan Mountains to the Himalayas. The main uses of this family are medicinal and ornamental. Dianthus superbus, Pseudostellaria heterophylla, Stellaria dichotoma var. lanceolata, and Vaccaria hispanica are commonly used in traditional Chinese medicine. Some species of Arenaria, Dianthus, Gypsophila, Psammosilene, and Silene are used as medicinal herbs among the people or are habitually used in local Chinese medicine. Many species of Dianthus, Gypsophila, Lychnis, Saponaria, and Silene are grown as ornamentals. Atocion armeria (Linnaeus) Rafinesque (Silene armeria Linnaeus), native to Russia and Europe, is also cultivated in China. It differs from Silene in having a corymbose inflorescence and obscure calyx veins. Wu Cheng-yih, Ke Ping, Zhou Li-hua, Tang Chang-lin & Lu De-quan. 1996. Caryophyllaceae.

RABELER University of Michigan Herbarium – EEB, 3600 Varsity Drive, Ann Arbor, MI 48108-2228, USA. [email protected] Four new combinations in Shivparvatia (Alsineae, Caryophyllaceae) are made to accommodate placement of all currently recognized taxa of Arenaria subg. Solitariae within the genus Shivparvatia. Keywords: Arenaria, nomenclature Introduction Sadeghian et al. (2015) completed the most recent, comprehensive analyses of Arenaria Linnaeus (1753: 423) in the broad sense. They confirmed the results of earlier studies by Harbaugh et al. (2010) and Greenberg and Donoghue (2011), showing that Arenaria s.s., Eremogone Fenzl (1833: 13), and Odontostemma Bentham ex G.Don (1831: 431) are each in different clades and are each monophyletic. In addition, they showed that Arenaria subg. Solitariae McNeill (1962: 128) is sister to Odontostemma and Arenaria subg. Dolophragma (Fenzl 1836: 63) McNeill (1962: 127) appears distantly related to any Arenaria species; both of these subgenera should also be excluded from Arenaria and treated as distinct genera. With only four names currently available in Shivparvatia Pusalkar & D.K.Singh (2015: 81), provided by Pusalkar & D.K.Singh (2015) for species found in India, four new combinations are required to allow placing the remaining taxa currently recognized in Arenaria subg. Solitariae within Shivparvatia. Methods The information about type specimens of the basionyms of the new combinations that I have included is based on examining protologues and searching major indices (Tropicos,org; JSTOR Global Plants) as well as websites of several individual herbaria, e.g.

Wolfe) ABSTRACT A fundamental question in evolutionary ecology is how species adjust post colonization. The plant Silene latifolia was introduced to North America (NA) from Europe (EU) in the 1800s. The goal of this thesis was to test if Silene latifolia has become locally adapted across its range. My first experiment tested local adaptation of germination success to three temperatures across three latitudinal regions in a growth chamber using seeds from nine EU and NA populations. Germination success or speed was similar among latitudinal regions across continents. My second experiment examined local adaptation at a continental scale; I grew plants from 15 EU and NA populations in four common gardens across continents. Growth and survival for the first year revealed that plants grew larger in their respective continents.

This challenge is most serious in tribe Caryophylleae since the supposed genera seem to be highly artificial, and the available morphological evidence cannot effectively be used for delimitation and exact determination of taxa. The main goal of the present study was to re-assess the monophyly of the genera currently recognized in this tribe using molecular phylogenetic data. We used the sequences of nuclear ribosomal internal transcribed spacer (ITS) and the chloroplast gene rps16 for 135 and 94 accessions, respectively, representing all 16 genera currently recognized in the tribe Caryophylleae, with a rich sampling of Gypsophila as one of the most heterogeneous groups in the tribe.

Hamzeloo-Moghadam2 1Traditional Medicine and Materia Medica Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran. 2Department of Traditional Pharmacy, School of Traditional Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran. Abstract Cancer is a major cause of death worldwide and causes serious problems in human life. It is developed by uncontrolled growth of a cell or a group of cells. There are many difficulties in treatment of cancer and many researchers are involved in investigating for effective drugs to treat the disease. Caryophyllaceae is a large family of about 86 genera and 2200 herbaceous or subshrub species. The family is known for its ornamental plants and saponin compounds. In the present study, the potential cytotoxic activity of 17 selected species from Caryophyllaceae has been investigated against MCF-7, HepG-2, A-549, HT-29 and MDBK cells using MTT assay. Five species exhibited cytotoxic effects with IC50 values < 100 μg/mL. Silene ampullata and Acanthophyllum bracteatum extracts were toxic only against MCF-7 cell line suggesting them as suitable candidates for more investigations of breast cancer studies. Keywords: Caryophyllaceae, cytotoxic activity, MTT assay Introduction Cancer is known as the second cause of death with lower side effects. Medicinal plants as worldwide and is characterized by the failure in natural compounds represent a vast potential the regulation of the tissue growth that results in resource for anticancer researches [3].

Owing to the rapid proliferation of callus tissues, in vitro production of avonoids has their own specic importance. Callus cultures raised followed by auxin directed biosynthesis of avonoid through related transcript prole were carried out. Murashige and Skoog (MS) medium fortied with 2,4- Dichlorophenoxy acetic acid (2,4- D) or picloram induced formation of friable callus from internode derived cultures of D. chinensis. Culture medium containing 2,4- D (10 µM) produced the highest avonoid content, 4.44 mg quercetin equivalent per gram (QE g− 1) under incubation in continuous dark condition, while maximum dry weight yield (0.38 g/ culture) was obtained from 10 µM 2,4- D under 16 h light / 8 h dark condition (50 µmol m− 2 s− 1 irradiance) at 60 days of incubation. The callus raised in light condition in 10 µM 2,4- D selected to analyze avonoid related gene expression prole viz., chalcone synthase (CHS), chalcone isomerase (CHI), avanone-3-hydroxylase (F3H), and avonol synthase (FLS) at specic time intervals.
