Vestured Pits in Wood of Onagraceae: Correlations with Ecology, Habit, and Phylogeny1
VESTURED PITS IN WOOD OF Sherwin Carlquist2 and Peter H. Raven3 ONAGRACEAE: CORRELATIONS WITH ECOLOGY, HABIT, AND PHYLOGENY1 ABSTRACT All Onagraceae for which data are available have vestured pits on vessel-to-vessel pit pairs. Vestures may also be present in some species on the vessel side of vessel-to-ray pit pairs. Herbaceous Onagraceae do not have fewer vestures, although woods with lower density (Circaea L. and Oenothera L.) have fewer vestures. Some Onagraceae from drier areas tend to have smaller vessel pits, and on that account may have fewer vestures (Epilobium L. and Megacorax S. Gonz´alez & W. L. Wagner). Pit apertures as seen on the lumen side of vessel walls are elliptical, occasionally oval, throughout the family. Vestures are predominantly attached to pit aperture margins. As seen from the outer surfaces of vessels, vestures may extend across the pit cavities. Vestures are usually absent or smaller on the distal portions of pit borders (except for Ludwigia L., which grows consistently in wet areas). Distinctive vesture patterns were observed in the several species of Lopezia Cav. and in Xylonagra Donn. Sm. & Rose. Vestures spread onto the lumen-facing vessel walls of Ludwigia octovalvis (Jacq.) P. H. Raven. Although the genera are presented here in the sequence of a recent molecular phylogeny of Onagraceae, ecology and growth forms are more important than evolutionary relationships with respect to abundance, degree of grouping, and morphology of vestured pits. Designation of vesture types is not warranted based on the distribution of named types in Onagraceae and descriptive adjectives seem more useful, although more data on vesturing in the family are needed before patterns of diversity and their extent can be fully ascertained. -

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.

After graduation from college, he moved to Eastern Oklahoma State College where he took a position as Instructor in Botany and Agronomy. In the course of conducting botany field trips and working with local residents on their plant problems, the author became increasingly interested in the flora of that area and of the State of Oklahoma. This led to an extensive study of the northern portion of the Oauchita Highlands with collections currently numbering approximately 4,200. The specimens have been processed according to standard herbarium procedures. The first set has been placed in the Herbarium of Oklahoma State University with the second set going to Eastern Oklahoma State College at Wilburton. Editor’s note: The original species list included habitat characteristics and collection notes. These are omitted here but are available in the dissertation housed at the Edmon-Low Library at OSU or in digital form by request to the editor. [SS] PHYSICAL FEATURES Winding Stair Mountain ranges.

Unpublished report. April 2009. 62 pages plus appendices. INTRODUCTION The Virginia Department of Conservation and Recreation's Division of Natural Heritage (DCR-DNH) was established to protect Virginia's Natural Heritage Resources. These Resources are defined in the Virginia Natural Area Preserves Act of 1989 (Section 10.1-209 through 217, Code of Virginia), as the habitat of rare, threatened, and endangered plant and animal species; exemplary natural communities, habitats, and ecosystems; and other natural features of the Commonwealth. DCR-DNH is the state's only comprehensive program for conservation of our natural heritage and includes an intensive statewide biological inventory, field surveys, electronic and manual database management, environmental review capabilities, and natural area protection and stewardship. Through such a comprehensive operation, the Division identifies Natural Heritage Resources which are in need of conservation attention while creating an efficient means of evaluating the impacts of economic growth. To achieve this protection, DCR-DNH maintains lists of the most significant elements of our natural diversity. -

A Vascular Plant Survey for Big Thicket National Preserve
DRAFT FINAL REPORT Big Thicket National Preserve National Park Service Beaumont, TX A Vascular Plant Survey for Big Thicket National Preserve Principal Investigator: P.A. Harcombe Department of Ecology and Evolutionary Biology Rice University Houston, TX 77005 National Park Service Cooperative Agreement CA14001004 May 29, 2007 - 1 - - 2 - INTRODUCTION The goal of the project was to produce verified inventories of vascular plant species (including ferns and fern allies) by unit in the Big Thicket National Preserve (BTNP), a part of the National Park System located in southeastern Texas in Hardin, Tyler, Polk, Liberty, Jefferson, Orange and Jasper counties. Collection efforts focused on the major units (Big Sandy, Hickory Creek, Turkey Creek, Beech Creek, Lance Rosier, Neches Bottom/Jack Gore Baygall, Beaumont). Owing to time constraints collecting in Loblolly Unit and Menard Creek was minimal, and no new collecting was done in the other corridor units (Pine Island Bayou, Upper Neches, and Lower Neches). Between June 2001 and December 2006, a database of 8095 specimen records was compiled. The database contains 1384 valid names representing 1264 distinct taxa in 536 genera and 146 families . From the database, final species and specimen tables were generated. A total of 7198 specimens were delivered to Dale Kruse, Curator, Tracey Herbarium at Texas A&M University (TAES) on April 6, 2007. In this report we describe methods used in constructing the database, the collectors, and the unit-level collection efforts. A species-by-unit table is presented; collection results are compared with Watson (1982), and there is an examination of variation in species richness among units. -

The current recommended plant selections for Mid- Atlantic pollinator habitats primarily provide resources for common or generalist pollinators. However, such plants may not foster uncommon or rare Mid-Atlantic specialist pollinators, whose populations are susceptible to harm from anthropogenic threats. This manuscript presents the first catalog of native specialist bees and associated host plants for the Mid-Atlantic. Approximately 29% of Mid-Atlantic native bee species are pollen specialists. -
Loss of Sexual Recombination and Segregation Is Associated with Increased Diversification in Evening Primroses

We test this hypothesis by estimating rates of speciation, extinction, and transition between sexuality and functional asexuality in the evening primroses. Specifically, we estimate these rates using the recently developed BiSSE (Binary State Speciation and Extinction) phylogenetic comparative method, which employs maximum likelihood and Bayesian techniques. We infer that net diversification rates (speciation minus extinction) in functionally asexual evening primrose lineages are roughly eight times faster than diversification rates in sexual lineages, largely due to higher speciation rates in asexual lineages. We further reject the hypothesis that a loss of recombination and segregation is irreversible because the transition rate from functional asexuality to sexuality is significantly greater than zero and in fact exceeded the reverse rate.
