Plants typically contain many bioactive compounds are used for medicinal purposes for several disease treatment. This study aimed to identify the plant species distribution in area of UiTM Kuala Pilah, providing research scientific data and to contribute to knowledge of the use of the plants as therapeutic resources. Three quadrat frames (1x1 m), which was labeled as Set 1, 2 and 3 was developed, in each set consists of 4 plots (A, B, C and D). Characteristics of plant species were recorded, identified and classified into their respective groups. Our findings show that the most representative classes were Magnoliopsida with the total value of 71.43%, followed by Liliopsida (17.86%) and Lecanoromycetes (10.71%). A total of 28 plant species belonging to 18 families were identified in all sets with the largest family of Rubiaceae.

Author for correspondence: Paul E. Berry, [email protected] Abstract Euphorbia subg. Chamaesyce contains around 600 species and includes the largest New World radiation within the Old World-centered genus Euphorbia. It is one of the few plant lineages to include members with C3, C4 and CAM photosyn- thesis, showing multiple adaptations to warm and dry habitats. The subgenus includes North American-centered groups that were previously treated at various taxonomic ranks under the names of “Agaloma ”, “Poinsettia ”, and “Chamaesyce ”. Here we provide a well-resolved phylogeny of Euphorbia subg. Chamaesyce using nuclear ribosomal ITS and chloroplast ndhF sequences, with substantially increased taxon sampling compared to previous studies. Based on the phylogeny, we discuss the Old World origin of the subgenus, the evolution of cyathial morphology and growth forms, and then provide a formal sectional classification, with descriptions and species lists for each section or subsection we recognize.

  • Hoover's Spurge 0 5 10 20 30 40 50 60
    Madera Irrigation District (Stebbins et al. 1995, California Natural Diversity Data Base 2003), and (5) the small population in San Joaquin County that is on land used for educational purposes by the University of California Cooperative Extension (California Natural Diversity Data Base 2003). 2. CHAMAESYCE HOOVERI (HOOVER’S SPURGE) a. Description and Taxonomy Taxonomy.—Hoover’s spurge is a member of the spurge family (Euphorbiaceae). This plant was originally named Euphorbia hooveri, based on a specimen collected by Hoover in Yettem, Tulare County (Wheeler 1940). At that time, the genus Euphorbia was viewed as comprising several subgenera, including Chamaesyce and Euphorbia. Webster (1975) subsequently elevated the subgenus Chamaesyce to the rank of genus based on growth patterns and physiology. The currently accepted scientific name, Chamaesyce hooveri, was validated when Koutnik (1985) published the new combination. Several other species of Chamaesyce have ranges similar to that of Chamaesyce hooveri and may occur in the same habitats. Chamaesyce ocellata ssp. ocellata (yerba golondrina) is yellowish-green, has untoothed leaves, and lacks appendages on the glands. Chamaesyce ocellata ssp. rattanii (Stony Creek spurge) has hairy stems and leaves and the gland appendages are entire. Chamaesyce serpyllifolia (thyme-leaved spurge) also has entire appendages and further differs from C. hooveri in microscopic characters of the female flower (Wheeler 1941, Munz and Keck 1959, Koutnik 1993). Description and Identification.—Chamaesyce hooveri (Figure II-3) trails along the ground, forming gray-green mats 5 to 100 centimeters (2.0 to 39.4 inches) in diameter (Broyles 1987, Stone et al. 1988). The stems are hairless and contain milky sap.

    The Herbaceous Vascular Plants of Blackacre Preserve A Preliminary List December 3, 2010 Submitted to: Kentucky State Nature Preserves Commission Submitted by: William E. Thomas Herbarium Indiana University Southeast Photo: Spiked Crested Coralroot by Richard Lyons 1 Scope The aim of this survey was to compile a rough list of herbaceous vascular plant species on the below described tract and was conducted from July 11, 2010 through the end of the growing season. In addition any extensive populations of invasive alien species were noted. Locale Description The Blackacre Preserve website states that the property consists of 170 acres in eastern Jefferson County Kentucky. It is the authors understanding that some additional acreage (size?) was appended to the southern border of the original 170 acre tract. The property is located at 3200 Tucker Station Rd. The tract is bordered on all sides by housing and urban areas; a railroad track runs along the north border. The terrain is of mostly gentle slopes with some wooded areas and open fields formerly used for pasture or crops. There are several ponds on the property; a limestone glade area constitutes the northeast corner of the tract. A small creek flows east to west across the tract north of the center. There are numerous foot trails, some designated and some rogue. An old section of Mann’s Lick road runs northward about midway in the tract. Map #1 from the Blackacre Preserve website provides a general layout of this tract. Map #2 is a topographic map with a NAD83 UTM 16 grid superimposed and the foot trails plotted in various colors.

  • Checklist of the Washington Baltimore Area
    Annotated Checklist of the Vascular Plants of the Washington - Baltimore Area Part I Ferns, Fern Allies, Gymnosperms, and Dicotyledons by Stanwyn G. Shetler and Sylvia Stone Orli Department of Botany National Museum of Natural History 2000 Department of Botany, National Museum of Natural History Smithsonian Institution, Washington, DC 20560-0166 ii iii PREFACE The better part of a century has elapsed since A. S. Hitchcock and Paul C. Standley published their succinct manual in 1919 for the identification of the vascular flora in the Washington, DC, area. A comparable new manual has long been needed. As with their work, such a manual should be produced through a collaborative effort of the region’s botanists and other experts. The Annotated Checklist is offered as a first step, in the hope that it will spark and facilitate that effort. In preparing this checklist, Shetler has been responsible for the taxonomy and nomenclature and Orli for the database. We have chosen to distribute the first part in preliminary form, so that it can be used, criticized, and revised while it is current and the second part (Monocotyledons) is still in progress. Additions, corrections, and comments are welcome. We hope that our checklist will stimulate a new wave of fieldwork to check on the current status of the local flora relative to what is reported here. When Part II is finished, the two parts will be combined into a single publication. We also maintain a Web site for the Flora of the Washington-Baltimore Area, and the database can be searched there (http://www.nmnh.si.edu/botany/projects/dcflora).
