  • Species Relationships and Farina Evolution in the Cheilanthoid Fern
    Systematic Botany (2011), 36(3): pp. 554–564 © Copyright 2011 by the American Society of Plant Taxonomists DOI 10.1600/036364411X583547 Species Relationships and Farina Evolution in the Cheilanthoid Fern Genus Argyrochosma (Pteridaceae) Erin M. Sigel , 1 , 3 Michael D. Windham , 1 Layne Huiet , 1 George Yatskievych , 2 and Kathleen M. Pryer 1 1 Department of Biology, Duke University, Durham, North Carolina 27708 U. S. A. 2 Missouri Botanical Garden, P.O. Box 299, St. Louis, Missouri 63166 U. S. A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Lynn Bohs Abstract— Convergent evolution driven by adaptation to arid habitats has made it difficult to identify monophyletic taxa in the cheilanthoid ferns. Dependence on distinctive, but potentially homoplastic characters, to define major clades has resulted in a taxonomic conundrum: all of the largest cheilanthoid genera have been shown to be polyphyletic. Here we reconstruct the first comprehensive phylogeny of the strictly New World cheilanthoid genus Argyrochosma . We use our reconstruction to examine the evolution of farina (powdery leaf deposits), which has played a prominent role in the circumscription of cheilanthoid genera. Our data indicate that Argyrochosma comprises two major monophyletic groups: one exclusively non-farinose and the other primarily farinose. Within the latter group, there has been at least one evolutionary reversal (loss) of farina and the development of major chemical variants that characterize specific clades. Our phylogenetic hypothesis, in combination with spore data and chromosome counts, also provides a critical context for addressing the prevalence of polyploidy and apomixis within the genus. Evidence from these datasets provides testable hypotheses regarding reticulate evolution and suggests the presence of several previ- ously undetected taxa of Argyrochosma.

  • Four Western Cheilanthoid Ferns in Oklahoma
    Oklahoma Native Plant Record 65 Volume 10, December 2010 FOUR WESTERN CHEILANTHOID FERNS IN OKLAHOMA Bruce A. Smith McLoud High School McLoud, Oklahoma 74851 Keywords: arid, distribution, habitat, key ABSTRACT The diversity of ferns in some of the more arid climates of western Oklahoma is surprising. This article examines four Oklahoma cheilanthoid ferns: Astrolepis integerrima, Cheilanthes wootonii, Notholaena standleyi, and Pellaea wrightiana. With the exceptions of A. integerrima and P. wrightiana which occur in Alabama and North Carolina respectively, all four species reach their eastern limits of distribution in Oklahoma. Included in this article are common names, synonyms, brief descriptions, distinguishing characteristics, U.S. and Oklahoma distribution, habitat information, state abundance, and a dichotomous key to selected cheilanthoids. The Oklahoma Natural Heritage Inventory has determined that all but one (N. standleyi) are species of concern in the state.

  • Driftless Area National Wildlife Refuge
    DRIFTLESS AREA NATIONAL WILDLIFE REFUGE McGregor, Iowa ANNUAL NARRATIVE REPORT FY2006 DRIFTLESS AREA NATIONAL WILDLIFE REFUGE McGregor, Iowa Fiscal Year 2006 _________________________ Prepared by Date _________________________ ______________________________ Refuge Manager Date Complex Manager Date ______________________________ Regional Chief, NWRS Date INTRODUCTION 1. Location The Driftless Area National Wildlife Refuge was established in 1989 for the protection and recovery of the threatened Northern monkshood and endangered Iowa Pleistocene snail. These species occur on a rare habitat type termed algific talus slopes. These are slopes with outflows of cold underground air that provide a glacial relict habitat to which certain species have adapted (see diagram below). The Driftless Area National Wildlife Refuge consists of ten units scattered throughout Allamakee, Clayton, Dubuque, and Jackson Counties in northeast Iowa. Total Refuge acreage is 811 acres with individual units ranging from 6 to 208 acres. Acquisition targets not only the algific slope, but surrounding buffer habitat that includes sinkholes important to air flow to the slope. Acquisition is ongoing, but limited due to insufficient funds. 2. Topography Refuge units are primarily forested and generally consist of steep topography with narrow creek valleys, large rock outcroppings, and karst features. Riparian and grassland habitat also occur on the Refuge. 3. Points of Interest The algific talus slope habitat of the Refuge harbors many unusual and rare plant and land snail species, some of which are also on the state threatened and endangered species list. These areas tend to be scenic with cliffs and rock outcroppings, springs, and coldwater streams. 4. Physical Facilities The Refuge office is located at the McGregor District of the Upper Mississippi River National Wildlife and Fish Refuge, McGregor, Iowa.

Since 1995, 20 fern taxa have been added to the Arkansas fern flora as new and naturalized, including Arachnioides simplicior , Athyrium nipponicum ‘Pictum’, Cyrtomium falcatum , C. fortunei , Dryopteris erythrospora , Hypolepis tenuifolia , Marsilea mutica , M. quadrifolia , Matteuccia struthiopteris , Nephrolepis exaltata , Polystichum tsus-sinense , Phegopteris decursive-pinnata , Salvinia minima , S. molesta , Selaginella braunii , S. kraussiana , S. k. ‘Aurea’, S. k. ‘Brownii’, S. k. ‘Goldtips’, and S. uncinata . Of the reported Arkansas naturalized ferns, one was deleted (C. fortunei ), being without a known voucher. There are now 97 native and 24 naturalized fern taxa known and documented in the Arkansas fern flora. The total Arkansas fern flora is now 121 taxa documented with 3019 county-level occurrence records. Noteworthy update records and comments are reported for 79 of 97 Arkansas native species and 25 Arkansas naturalized species. KEY WORDS : Arkansas, ferns, county distribution Over the last 30 years, studies have been conducted to document the diversity and abundance of the Arkansas fern [pteridophyte] flora.

It appears to be a glacial relict, existing today only in unique areas with cool, moist microenvironments, such as algific talus slopes.

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.
