It blooms in spring and occurs in wet meadows and streamsides in the mountains and valleys over much of northern Utah. Hesperochiron can be distinguished from other members of the waterleaf family (Hydrophyllaceae) by having a basal rosette of en- tire, spoon-shaped leaves. Recent biosystematic research suggests that the Hydrophyllaceae is nested within the larger borage family and should be lumped with it (a position taken by some taxonomists in the 19th and early 20th centuries based on morphological grounds).

The flowers are white to cream and up to 1 inch across with few to many in the leaf axils. Male and female flowers are on separate plants. The female plants are the most attractive with fruits having feathery styles to 2 inches long. The plants occur naturally along road- sides or in thickets usually climbing on fences, trees, or shrubs in the ba- sins, valleys, and plains. They prefer full sun or partial shade and moist to dry, well-drained soil. This is a vigor- ous grower but can be pruned heavily if desirable. It can be grown from seed after removing the styles.

Calochortiana Volume 2 Deadline: The deadline for submissions for the second edition of the Utah Native Plant Society’s annual technical journal, Calochortiana, has been extended to 15 October 2013 to better accommodate authors and reviewers. The inaugural issue is posted on the UNPS homepage (www.unps.org). Calochortiana provides a forum for articles on the natural history of native plants of Utah, protocols on growing native species, floristic checklists, and other contributions that are not readily accepted in other journals—and at no cost to contributors! Space is limited, however. For more information on format and review requirements, potential authors should contact Calo- chortiana editor, Walter Fertig ([email protected]). Volume 2 of the journal is slated for December 2013. Wetland Plant Guide Available: The Colorado Natural Heritage Program is excited to announce the completion of the Field Guide to Colorado’s Wetland Plants: Identification, Ecology, and Conservation. The field guide combines available wetland information into an easy-to-use resource designed for both the lay person as well as the wetland scientist to not only identify wetland plants, but to apply that knowledge towards proactive conservation and protection of one of Colo- rado’s most valuable resources. The Field Guide contains botanical descriptions of over 600 wetland plants as well as information on priority wildlife species and other wetland-dependent animals, wildlife and vegetation ecology, and rare or sensitive plants. The Guide not only assists with identifying a wetland plant, but includes information on its wetland indicator status, classification, conservation status, rarity, and ecology. The Field Guide is available for $39.95 plus tax and shipping from CHNP’s website: http://www.cnhp.colostate.edu/cwic/ident/fieldGuide.aspx. Unidentified Flowering Object This month’s UFO was provided by John Toolen of the BLM Grand Junction Field Office, who took the photo on Mancos Shale of northwestern Colorado. This annual is also found in badlands habitats in Grand and Uintah coun- ties in Utah. It can be taller than the photo shows, but the (mostly) entire leaves are distinctive. Any guesses? The July UFO photo was a close-up of the inflorescence of Rigid spineflower (Chorizanthe rigida). This 1-4 inch tall annual has spiny bracts below the greenish flowers that form a bur-like skeleton that persists long after the plant has set seed and died. In the interests of full disclo- sure, I took the photo this spring south of Mesquite, Ne- vada. In Utah Rigid spineflower is restricted to warm de- sert and Joshua tree habitats in the Beaver Dam Wash area. Congratulations to Lee Hughes for submitting the first correct response.

Bot. 21 (1): 01-09. Tehran. Piptatherum denaense is described as a new species from south west of Iran, Dena Mountain. It is close to P. laterale but differs from it by having glabrous lemma in lower half and toward the apex, narrower vegetative shoots and unbearded anthers. Piptatherum holciforme subsp. holciforme var. glabrum is not accepted as a distinct variety. Piptatherum sphacelatum formerly known as a synonym of P. molinioides is established as a separate species due to having distinct morphological characters as well as molecular differences based on literature. Thus, the number of taxa in the genus Piptatherum changes to 9 species, 2 subspecies and 4 varieties in Iran. An identification key to Piptatherum taxa occuring in Iran is provided.

    Preliminary Report on the Reproductive Biology of the Threatened Chisos Mountain Hedgehog Cactus BONNIE B. AMOS and CHRISTOS VASSILIOU Angelo State University, Texas Abstract: The Chisos Mountain hedgehog cactus (Echinocereus chisoensis, Cactaceae) is a narrow endemic restricted to an approximately 100 square mile area in Big Bend National Park, Texas. It was listed as threatened in 1987 as Echinocereus chisoensis var. chisoensis. An investigation of the reproductive biology and pollination ecology conducted in 1999 and 2000 revealed the taxon to be homogamous, self-incompatible, xenogamous, and heavily dependent upon the cactus oligolectic bee, Diadasia rinconis (Anthophoridae) for pollination. Despite infrequent bee visitation, fruit set from open pollination is high and fruits produce large numbers of seeds. Predation in 2002, probably from rodents as a result of severe drought conditions, was severe on plants, flower buds, and fruits. The Chisos Mountain hedgehog cactus, or Chisos jillo (Opuntia leptocaulis DC.), ocotillo (Fouquieria pitaya (Echinocereus chisoensis W. Marshall), is 1 of splendens K.

S. HITCHCOCK z rit erV ^-C?^ 1 " WASHINGTON GOVERNMENT PRINTING OFFICE 1908 BULLETIN OF THE UNITED STATES NATIONAL MUSEUM Issued June 18, 1908 ii PREFACE The accompanying paper, by Prof. A. S. Hitchcock, Systematic Agrostologist of the United States Department of Agriculture, u entitled Types of American grasses: a study of the American species of grasses described by Linnaeus, Gronovius, Sloane, Swartz, and Michaux," is an important contribution to our knowledge of American grasses. It is regarded as of fundamental importance in the critical sys- tematic investigation of any group of plants that the identity of the species described by earlier authors be determined with certainty. Often this identification can be made only by examining the type specimen, the original description being inconclusive. Under the American code of botanical nomenclature, which has been followed by the author of this paper, "the nomenclatorial t}rpe of a species or subspecies is the specimen to which the describer originally applied the name in publication." The procedure indicated by the American code, namely, to appeal to the type specimen when the original description is insufficient to identify the species, has been much misunderstood by European botanists. It has been taken to mean, in the case of the Linnsean herbarium, for example, that a specimen in that herbarium bearing the same name as a species described by Linnaeus in his Species Plantarum must be taken as the type of that species regardless of all other considerations.

    APPENDIX D.2 Plant Survey Memorandum Athos Memo Report To: Aspen Environmental Group From: Lehong Chow, Ironwood Consulting, Inc. Date: April 3, 2019 Re: Athos Supplemental Spring 2019 Botanical Surveys This memo report presents the methods and results for supplemental botanical surveys conducted for the Athos Solar Energy Project in March 2019 and supplements the Biological Resources Technical Report (BRTR; Ironwood 2019) which reported on field surveys conducted in 2018. BACKGROUND Botanical surveys were previously conducted in the spring and fall of 2018 for the entirety of the project site for the Athos Solar Energy Project (Athos). However, due to insufficient rain, many plant species did not germinate for proper identification during 2018 spring surveys. Fall surveys in 2018 were conducted only on a reconnaissance-level due to low levels of rain. Regional winter rainfall from the two nearest weather stations showed rainfall averaging at 0.1 inches during botanical surveys conducted in 2018 (Ironwood, 2019). In addition, gen-tie alignments have changed slightly and alternatives, access roads and spur roads have been added. PURPOSE The purpose of this survey was to survey all new additions and re-survey areas of interest including public lands (limited to portions of the gen-tie segments), parcels supporting native vegetation and habitat, and windblown sandy areas where sensitive plant species may occur. The private land parcels in current or former agricultural use were not surveyed (parcel groups A, B, C, E, and part of G). METHODS Survey Areas: The area surveyed for biological resources included the entirety of gen-tie routes (including alternates), spur roads, access roads on public land, parcels supporting native vegetation (parcel groups D and F), and areas covered by windblown sand where sensitive species may occur (portion of parcel group G).

    Vascular Plant Species Diversity of Mt. Etna

    Vascular plant species diversity of Mt. Etna (Sicily): endemicity, insularity and spatial patterns along the altitudinal gradient of the highest active volcano in Europe Saverio Sciandrello*, Pietro Minissale* and Gianpietro Giusso del Galdo* Department of Biological, Geological and Environmental Sciences, University of Catania, Catania, Italy * These authors contributed equally to this work. ABSTRACT Background. Altitudinal variation in vascular plant richness and endemism is crucial for the conservation of biodiversity. Territories featured by a high species richness may have a low number of endemic species, but not necessarily in a coherent pattern. The main aim of our research is to perform an in-depth survey on the distribution patterns of vascular plant species richness and endemism along the elevation gradient of Mt. Etna, the highest active volcano in Europe. Methods. We used all the available data (literature, herbarium and seed collections), plus hundreds of original (G Giusso, P Minissale, S Sciandrello, pers. obs., 2010–2020) on the occurrence of the Etna plant species. Mt. Etna (highest peak at 3,328 mt a.s.l.) was divided into 33 belts 100 m wide and the species richness of each altitudinal range was calculated as the total number of species per interval. In order to identify areas with high plant conservation priority, 29 narrow endemic species (EE) were investigated through hot spot analysis using the ``Optimized Hot Spot Analysis'' tool available in the ESRI ArcGIS software package. Results. Overall against a floristic richness of about 1,055 taxa, 92 taxa are endemic, Submitted 7 November 2019 of which 29 taxa are exclusive (EE) of Mt.
