The Genus Brassavola, (L.) R.Br
The Genus Brassavola, (L.) R.Br. in W.T.Aiton, Hortus Kew. 5: 216 (1813) Type: Brassavola [B.] cucullata [bra-SAH-vo-la kyoo-kyoo-LAH-ta] There are 28 species (OrchidWiz [update Dec 2017]) that are epiphytes and sometimes lithophytes at elevations of from sea level to 3300 ft (1000 m) from Mexico, southern Caribbean islands to northern Argentina in moist or wet montane forests, mangroves, rocky crevices and cliff faces. They are most fragrant at night and many with a citrus smell. The genus is characterized by very small pencil-like pseudobulbs, often forming large clumps; a single, fleshy, apical, sub-terete leaf and the inflorescence produced form the apex of the pseudobulb. The inflorescence carries from a single to a few large flowers. The floral characteristics are elongate narrow similar sepals and petals, the base of the lip usually tightly rolled around at least a portion of the column which carries 12, sometimes eight unequal pollina with prominent opaque caudicles. The flowers usually occur, as a rule, in spring, summer and fall. The flowers are generally yellow to greenish white with a mostly white lip. It is not unusual for dark spots, usually purple, to be in the region where the sepals, petals, and lip join the stem (claw). This spotting is a dominant generic trait in Brassavola nodose. They are easily cultivated under intermediate conditions. Although this is a relatively small genus (28 species), the species show an unusually close relationship with one another in their floral patterns, coloration, and column structure making identification difficult, key to know where the plants were collected. -

Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE
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. -
NATIONAL WETLANDS INVENTORY and the NATIONAL WETLANDS RESEARCH CENTER PROJECT REPORT FOR: GALVESTON BAY INTRODUCTION the U.S. Fi
NATIONAL WETLANDS INVENTORY AND THE NATIONAL WETLANDS RESEARCH CENTER PROJECT REPORT FOR: GALVESTON BAY INTRODUCTION The U.S. Fish & Wildlife Service's National Wetlands Inventory is producing maps showing the location and classification of wetlands and deepwater habitats of the United States. The Classification of Wetlands and Deepwater Habitats of the United States by Cowardin et al. is the classification system used to define and classify wetlands. Upland classification will utilize the system put forth in., A Land Use and Land Cover Classification System For Use With Remote Sensor Data. by James R. Anderson, Ernest E. Hardy, John T. Roach, and Richard E. Witmer. Photo interpretation conventions, hydric soils-lists and wetland plants lists are also available to enhance the use and application of the classification system. The purpose of the report to users is threefold: (1) to provide localized information regarding the production of NWI maps, including field reconnaissance with a discussion of imagery and interpretation; (2) to provide a descriptive crosswalk from wetland codes on the map to common names and representative plant species; and (3) to explain local geography, climate, and wetland communities. II. FIELD RECONNAISSANCE Field reconnaissance of the work area is an integral part for the accurate interpretation of aerial photography. Photographic signatures are compared to the wetland's appearance in the field by observing vegetation, soil and topography. Thus information is weighted for seasonality and conditions existing at the time of photography and at ground truthing. Project Area The project area is located in the southeastern portion of Texas along the coast. Ground truthing covered specific quadrangles of each 1:100,000 including Houston NE, Houston SE, Houston NW, and Houston SW (See Appendix A, Locator Map). -
Texas Coast Salt and Brackish Tidal Marsh
ECOLOGICAL MAPPING SYSTEMS OF TEXAS: TEXAS COAST SALT AND BRACKISH TIDAL MARSH TEXAS COAST SALT AND BRACKISH TIDAL MARSH Nature Serve ID: CES203.473 Geology: Recent alluvial and eolian deposits along the coast. Landform: Nearly level very gentle slopes, and flats influenced by tides. Soils: Coastal sands and various Salt Marsh Ecological Sites. Description: These marshes occupy relatively low-lying, coastal situations on level landforms influenced by tidal fluctuations. Some sites are only influenced by storm tides, or tides resulting from extreme wind events. The composition of these marshes is primarily influenced by the frequency and duration of tidal inundation. Salinity on some marshes, particularly in the south, is maintained by salt spray from prevailing southeasterly winds. Low marshes are regularly flooded and representative examples are dominated by Spartina alterniflora (smooth cordgrass), Juncus roemerianus (blackrush), or Avicennia germinans (black mangrove). Significant areas of Avicennia germinans (black mangrove) become more frequent towards the south, while extensive areas of Spartina alterniflora (smooth cordgrass) become rare south of Corpus Christi Bay. Areas of decreased frequency and/or duration of tidal inundation are often referred to as high, or irregularly flooded, marsh. These marshes may be dominated by species such as Spartina patens (marshhay cordgrass), Distichlis spicata (saltgrass), Schoenoplectus robustus (sturdy bulrush), Schoenoplectus americanus (three-square bulrush), Sporobolus virginicus (seashore dropseed), Monanthochloe littoralis (shoregrass), and Spartina spartinae (Gulf cordgrass). Shrubs, subshrubs, and forbs, such as Batis maritima (saltwort), Borrichia frutescens (sea ox-eye daisy), Sesuvium portulacastrum (shoreline seapurslane), Salicornia spp. (glassworts), Suaeda linearis (annual seepweed), Limonium spp. (sea-lavenders), and Lycium carolinianum (Carolina wolfberry) are commonly encountered in these marshes. -

FLORIDA GOLDEN ASTER Chrysopsis Floridana
FLORIDA GOLDEN ASTER Chrysopsis floridana Above: Photo of Florida Golden Aster flower cluster. Photo courtesy of Laurie Markham. Left: Photo of Florida Golden Aster plant. Photo courtesy of Laurie Markham. FAMILY: Asteraceae (Aster family) STATUS: Endangered (Federal Register, May 16, 1986) DESCRIPTION AND REPRODUCTION: Young plants of this perennial herb form rosettes with leaves that are covered with dense, white, short-wooly hairs. Upright stems that grow from the rosettes are 0.3-0.4 meters (1-1.5 feet) tall, with closely-spaced, obovate-elliptic, hairy leaves. The leaves are nearly as large at the top of the stem as at the bottom. The flower heads are arranged in a more or less flat-topped cluster. Each head is slightly over 2.5 centimeters (1 inch) in diameter. Both the central disc and the rays are yellow. This plant is short-lived, and reproduces entirely by seeds. Its seeds are apparently dispersed primarily by the wind. RANGE AND POPULATION LEVEL: Florida golden aster is currently known from Hardee, Hillsborough, Manatee and Pinellas Counties, Florida. 2004 surveys on Hillsborough County lands have discovered several new populations (Cox et al. 2004). Additional survey will be conducted in 2005 on additional Hillsborough and Manatee Counties land. Systematic surveys should be continued and De Soto and Sarasota Counties should be included in this search. Historic sites include Long Key (St. Petersburg Beach) in Pinellas County, and Bradenton Beach and Bradenton in Manatee County. HABITAT: The species grows in open, sunny areas. It occurs in sand pine-evergreen oak scrub vegetation on excessively-drained fine white sand. -

The Vascular Flora of the Lake Thoreau Environmental Center
THE VASCULAR FLORA OF THE LAKE THOREAU ENVIRONMENTAL CENTER, FORREST AND LAMAR COUNTIES, MISSISSIPPI, WITH COMMENTS ON COMPOSITIONAL CHANGE AFTER A DECADE OF PRESCRIBED FIRE William J. McFarland, Danielle Cotton, Mac H. Alford, Micheal A. Davis 118 College Dr., Box 5018 School of Biological, Environmental, and Earth Sciences The University of Southern Mississippi Hattiesburg, Mississippi 39406, U.S.A. [email protected] ABSTRACT Longleaf pine (Pinus palustris Mill.) ecosystems exhibit high species diversity and are major contributors to the extraordinary levels of regional biodiversity and endemism found in the North American Coastal Plain Province. These forests require frequent fire return inter- vals (every 2–3 years) to maintain this rich diversity. In 2009, a floristic inventory was conducted at the Lake Thoreau Environmental Center owned by the University of Southern Mississippi in Hattiesburg, Mississippi. The Center is located on 106 ha with approximately half cov- ered by a 100+ year old longleaf pine forest. When the 2009 survey was conducted, fire had been excluded for over 20 years resulting in a dense understory dominated by woody species throughout most of the forest. The 2009 survey recorded 282 vascular plant species. Prescribed fire was reintroduced in 2009 and reapplied again in 2010, 2012, 2014, 2016, and 2018. A new survey was conducted in 2019 to assess the effects of prescribed fire on floristic diversity. The new survey found an additional 268 species bringing the total number of plants species to 550. This study highlights the changes in species diversity that occurs when fire is reintroduced into a previously fire-suppressed system and the need to monitor sensitive areas for changes in species composition. -
Araceae) from South America and Notes on the Tribe Caladieae
Willdenowia 35 – 2005 333 JOSEF BOGNER & EDUARDO G. GONÇALVES Two new species of Xanthosoma (Araceae) from South America and notes on the tribe Caladieae Abstract Bogner, J. & Gonçalves, E. G.: Two new species of Xanthosoma (Araceae) from South America and notes on the tribe Caladieae. – Willdenowia 35: 333-344. – ISSN 0511-9618; © 2005 BGBM Berlin- Dahlem. doi:10.3372/wi.35.35216 (available via http://dx.doi.org/) Two new species of Xanthosoma sect. Acontias, X. mariae and X. latestigmatum, are described and il- lustrated. They have pilose, pedate leaf blades as have in Xanthosoma only X. plowmanii and X. pottii, and their pollen grains are released as monads, unlike in all other Xanthosoma species, which, as far as studied, release the pollen in tetrads. X. mariae is an evergreen plant mainly distinguished by its dark green velvety lustrous leaf blades with numerous leaflets and tuber-like swellings at the junction of petiole and blade; the gynoecium is of the Acontias type and the ovary is pilose in the lower part. X. latestigmatum is seasonally dormant and has medium green leaf blades with numerous leaflets and no tuber-like swellings; the gynoecium is of the Caladium type (with a very broad stigma) and completely glabrous. The relationship of the genera Caladium and Xanthosoma is discussed, C. paradoxum is transferred to Xanthosoma and the new combination X. paradoxum validated, and a key to the genera of the tribe Caladieae given. Introduction Two new species of Xanthosoma Schott cultivated in recent years in the Botanischer Garten München are described here. X. mariae has been collected only once in Peru by Mary Sizemore.
