  • Reticulate Evolution in the Parasitic Genus Cuscuta (Convolvulaceae): Over and Over Again1
    791 Reticulate evolution in the parasitic genus Cuscuta (Convolvulaceae): over and over again1 Sasˇa Stefanovic´ and Mihai Costea Abstract: The frequency and relative importance of hybridization in plants has been an area of intense debate. Although this evolutionary phenomenon has received considerable attention from plant biologists, there are no well-supported cases of reticulate evolution involving parasitic plants, to date. Recent molecular phylogenetic analyses revealed that the subge- nus Grammica, the largest and most diverse group of the stem-parasitic genus Cuscuta (dodder), consists of 15 major clades. We describe here five cases of strongly supported discordance between phylogenies derived from plastid and nu- clear data, and interpret them as results of five independent hybridization events. Three of these cases could represent rela- tively recent reticulations, as each of them involves more closely related species, always confined within the same major clade as their putative parental species, and are currently sympatric or parapatric with them. The two remaining cases in- volve species whose potential progenitors are derived from different major groups of Grammica, and which are allopatric in their present distribution. A series of statistical tests was conducted to assess and further explore the significance of this phylogenetic incongruence. Alternative explanations for discordant gene topologies are explored. Cuscuta liliputana sp. nov., a new Mexican species of hybrid origin is described. Key words: Convolvulaceae, Cuscuta, Cuscuta liliputana sp. nov., molecular phylogeny, parasitic plants, reticulate evolution. Re´sume´ : La fre´quence et l’importance relative de l’hybridation chez les plantes soule`vent d’intenses de´bats. Bien que ce phe´nome`ne e´volutif ait rec¸u beaucoup d’attention de la part des phytobiologistes, a` ce jour, on ne connaıˆt pas de cas bien e´tabli d’e´volution re´ticule´e impliquant des plantes parasites.

  • Floristic Quality Assessment Report
    FLORISTIC QUALITY ASSESSMENT IN INDIANA: THE CONCEPT, USE, AND DEVELOPMENT OF COEFFICIENTS OF CONSERVATISM Tulip poplar (Liriodendron tulipifera) the State tree of Indiana June 2004 Final Report for ARN A305-4-53 EPA Wetland Program Development Grant CD975586-01 Prepared by: Paul E. Rothrock, Ph.D. Taylor University Upland, IN 46989-1001 Introduction Since the early nineteenth century the Indiana landscape has undergone a massive transformation (Jackson 1997). In the pre-settlement period, Indiana was an almost unbroken blanket of forests, prairies, and wetlands. Much of the land was cleared, plowed, or drained for lumber, the raising of crops, and a range of urban and industrial activities. Indiana’s native biota is now restricted to relatively small and often isolated tracts across the State. This fragmentation and reduction of the State’s biological diversity has challenged Hoosiers to look carefully at how to monitor further changes within our remnant natural communities and how to effectively conserve and even restore many of these valuable places within our State. To meet this monitoring, conservation, and restoration challenge, one needs to develop a variety of appropriate analytical tools. Ideally these techniques should be simple to learn and apply, give consistent results between different observers, and be repeatable. Floristic Assessment, which includes metrics such as the Floristic Quality Index (FQI) and Mean C values, has gained wide acceptance among environmental scientists and decision-makers, land stewards, and restoration ecologists in Indiana’s neighboring states and regions: Illinois (Taft et al. 1997), Michigan (Herman et al. 1996), Missouri (Ladd 1996), and Wisconsin (Bernthal 2003) as well as northern Ohio (Andreas 1993) and southern Ontario (Oldham et al.

  • Cuscuta Coryli Engelm
    Cuscuta coryli Engelm. Common Names: Hazel dodder (3). Etymology: With Arabic origins, Kushkut, means dodder plant or parasitic plant; in New Latin, Cuscuta directly translates as dodder. Corylus converts to hazel in Greek. The species epithet, coryli, refers to the tendency to parasitize Corylus (1,2). Botanical synonyms (4): Cuscuta compacta var. crenulata (Engelm.) Choisy Cuscuta crenulata Engelm. Cuscuta inflexa Engelm. Epithymum coryli (Engelm.) Nieuwl. & Lunell Grammica coryli Family: Convolvulaceae, the morning glory family Quick Notable Features: ¬ Reduced stem and leaf structure ¬ Thread-like stem is 0.4-0.6mm in diameter ¬ Tiny flowers, ~1.5-2.5mm, with translucent yellowish-white petals, growing in cymose-paniculate clusters or compact glomerulate bunches ¬ Corolla lobes are inflexed ¬ Most often present in hazel (Corylus) fields Plant Height: The height of Cuscuta coryli is dependent on the host; H.L. Dean measured the length of a single dodder plant at nearly half a mile (14). Subspecies/varieties recognized (4): Cuscuta coryli var. coryli and Cuscuta coryli var. stylosa Engelm. Most Likely Confused with: Any other species of Cuscuta—in Michigan these might be: C. cephalathi, C. epilinum, C. epithymum, C. glomerata, C. indecora, C. pentagona or C. polygonorum. Habitat Preference: In Michigan, C. coryli parasitizes Amphicarpaea, Aster, Bidens, Ceanothus, Corylus, Euthamia, Mentha, Monarda, Solidago, Stachys and Symphoricarpos (6). It has also been noted in sandy areas along pond perimeters and low, dry surfaces (17). Geographic Distribution in Michigan: C. coryli is found in eight counties in Michigan’s Lower Peninsula: Cass, Kalamazoo, Monroe, Wayne, Oakland, St. Clair, Midland and Bay (6). Known Elevational Distribution: The altitudinal limit of C.

    157 NOTES ON OUR INDIANA DODDERS. T. G. YUNCKER. Dodder is the popular or common name ordinarily applied to species of Ouscuta. This genus belongs naturally to the Convolvulaceae. The re- markable embryogeny ; the structure of the mature plants ; the manner in which they secure their nourishment and their peculiar ecological rela- tionships make tliem subjects of particular scientific interest. Tliere are in Nortli America about lifty known native and five intro- duced species. Of the natives less than a half dozen are reported as harm- ful to economically important crops, and, of these, but one or two are of much importance. Of the introduced species four are distinctly harmful. Because of the trouble caused by this minority the whole genus is fre- quently considered in ill repute. Some authors, however, attempt to show that the harm done by a few members of the group is offset by the good done by the others in parasitizing harmful weeds and thus retarding their growtli. In the state of Indiana we have seven native and possibly two introduced species. Of these, one native, C. pcnfagoiia. and both of the introduced spe- cies are harmful to crops. The amount of harm caused by these parasites becomes considerable if they are not checked, in some cases causing nearly the total loss of the crop. The grower finding these plants in his fields should take immediate steps to <lestroy them. In the proper identification of the species one must oi-dinarily make a careful dissection of the flowers. After the flowers have been pressed and dried this usually means that they require softening by boiling and the subsequent dissection in water.

Brentwood Blvd. St. Louis, Missouri 63144 [email protected] JUSTIN R. THOMAS Institute of Botanical Training, LLC 111 County Road 3260 Salem, Missouri 65560 [email protected] ABSTRACT An annotated checklist of the 2,961 vascular taxa comprising the flora of Missouri is presented, with conservatism rankings for Floristic Quality Assessment. The list also provides standardized acronyms for each taxon and information on nativity, physiognomy, and wetness ratings. Annotated comments for selected taxa provide taxonomic, floristic, and ecological information, particularly for taxa not recognized in recent treatments of the Missouri flora. Synonymy crosswalks are provided for three references commonly used in Missouri. A discussion of the concept and application of Floristic Quality Assessment is presented. To accurately reflect ecological and taxonomic relationships, new combinations are validated for two distinct taxa, Dichanthelium ashei and D. werneri , and problems in application of infraspecific taxon names within Quercus shumardii are clarified.
