Anatomy of Flowering Plants
This page intentionally left blank Anatomy of Flowering Plants Understanding plant anatomy is not only fundamental to the study of plant systematics and palaeobotany, but is also an essential part of evolutionary biology, physiology, ecology, and the rapidly expanding science of developmental genetics. In the third edition of her successful textbook, Paula Rudall provides a comprehensive yet succinct introduction to the anatomy of flowering plants. Thoroughly revised and updated throughout, the book covers all aspects of comparative plant structure and development, arranged in a series of chapters on the stem, root, leaf, flower, seed and fruit. Internal structures are described using magnification aids from the simple hand-lens to the electron microscope. Numerous references to recent topical literature are included, and new illustrations reflect a wide range of flowering plant species. The phylogenetic context of plant names has also been updated as a result of improved understanding of the relationships among flowering plants. This clearly written text is ideal for students studying a wide range of courses in botany and plant science, and is also an excellent resource for professional and amateur horticulturists. Paula Rudall is Head of Micromorphology(Plant Anatomy and Palynology) at the Royal Botanic Gardens, Kew. She has published more than 150 peer-reviewed papers, using comparative floral and pollen morphology, anatomy and embryology to explore evolution across seed plants.

Approved Conservation Advice for Acacia Recurvata (Recurved Wattle)
This Conservation Advice was approved by the Minister / Delegate of the Minister on: 1/10/2008 Approved conservation advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for Acacia recurvata (Recurved Wattle) This Conservation Advice has been developed based on the best available information at the time this conservation advice was approved; this includes existing plans, records or management prescriptions for this species. Description Acacia recurvata, Family Mimosaceae, also known as Recurved Wattle, is a dense domed spreading shrub growing to 2.5 m high and 1–3 m across (Cowan & Maslin, 1999; Orchard & Wilson, 2001). The dark green to dull grey-green leaf-like phyllodes are narrow, growing to 2.5-4 cm long and 4-8 mm wide (Orchard & Wilson, 2001; World Wide Wattle, 2005). The small, golden, globular flower heads are paired (Brown et al., 1998) and borne in June–July (Brown et al., 1998; Cowan & Maslin, 1999; Patrick & Brown, 2001). Young pods have been collected in September (Patrick & Brown, 2001) and mature pods in October (Cowan & Maslin, 1999). Conservation Status Recurved Wattle is listed as endangered. This species is eligible for listing as endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as, prior to the commencement of the EPBC Act, it was listed as endangered under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). The species is also listed as rare (declared rare flora – extant) under the Wildlife Conservation Act 1950 (Western Australia). Distribution and Habitat Recurved Wattle is endemic to Western Australia, where it is restricted to four locations in the Coorow–Three Springs area, south-east of Geralton (Orchard & Wilson, 2001; Patrick & Brown, 2001; Western Australian Herbarium, 2007).

Biodiversity Summary: Avon, Western Australia
Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.

Fire and Reseeding Effects on Arizona Upland Plant Community Composition and A
Fire and Reseeding Effects on Arizona Upland Plant Community Composition and a Preliminary Floristic Inventory of Cave Creek Regional Park by Kara Lynn Barron A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science Approved November 2018 by the Graduate Supervisory Committee: Juliet Stromberg, Co-Chair Kathleen Pigg, Co-Chair Elizabeth Makings Kimberlie McCue ARIZONA STATE UNIVERSITY December 2018 ABSTRACT Baseline community composition data provides a snapshot in time that allows changes in composition to be monitored more effectively and can inform best practices. This study examines Arizona Upland plant community composition of the Sonoran Desert through three different lenses: floristic inventory, and fire and reseeding effects. A floristic inventory was conducted at Cave Creek Regional Park (CCRP), Maricopa County, AZ. One hundred fifty-four taxa were documented within Park boundaries, including 148 species and six infraspecific taxa in 43 families. Asteraceae, Boraginaceae, and Fabaceae accounted for 40% of documented species and annuals accounted for 56% of documented diversity. Fire effects were studied at three locations within McDowell Sonoran Preserve (MSP), Scottsdale, AZ. These fires occurred throughout the 1990s and recovered naturally. Fire and reseeding effects were studied at the site of a 2005 fire within CCRP that was reseeded immediately following the fire. Two questions underlie the study regarding fire and reseeding effects: 1) How did fire and reseeding affect the cover and diversity of the plant communities? 2) Is there a difference in distribution of cover between treatments for individual species or growth habits? To address these questions, I compared burned and adjacent unburned treatments at each site, with an additional reseeded treatment added at CCRP.
