Notes on a Hybrid Spearwort, Ranunculus Flammula L. X R
Watsonia, 16, 383-388 (1987) 383 Notes on a hybrid spearwort, Ranunculus flammula L. x R. reptans L. R. J. GORNALL Botany Department, The University, Leicester, LE] 7RH ABSTRACT Hybrid Creeping Spearworts (Ranunculus flammula L. x R. reptans L.) are given the binomial Ranunculus x levenensis Druce ex Gornall, hybr. novo The character most useful in distinguishing the hybrid from its parents is the relative length of the achene beak. In the British Isles, hybrids occur sporadically on a few northern lake shores; they also occur in southern Scandinavia, northern·central Germany and the Alps. Their presence in the British Isles is due to hybridization between native R. flammula and plants of R. rep tans that have probably been dispersed to these islands by waterfowl migrating from Iceland, Scandinavia and the northern part of the U.S.S.R. INTRODUCTION Padmore (1957) and Candlish [nee Padmore] (1975) concluded that the Creeping Spearworts in the British Isles are hybrid derivatives of Ranunculus flammula L. and R. reptans L. (Ranunculaceae). This hybrid hypothesis, which can be traced to Druce (1913), has received substantial experimental support (Gibbs & Gornall1976). Since most British collections are of the hybrid, rather than of R. reptans, it seems desirable to validate the binomial bestowed on them as a nomen nudum by Druce (1929a,b), so as to provide them with a convenient name. DESCRIPTION Ranunculus x levenensis Druce ex Gornall, hybr. novo TYPUS: Damp, sandy, and gravelly margin of Loch Leven, Kinross, Aug. 1912, G. C. Druce (Holotypus: OXF! Isotypi: BM' E! OXF! STA! and probably elsewhere). Specimens of artificially synthesized hybrids have been placed in LTR and STA. -

Fort Valley Experimental Forest-A Century of Research 1908-2008
Vascular Plant Checklist of the Chimney Spring and Limestone Flats Prescribed Burning Study Areas Within Ponderosa Pine Experimental Forests in Northern Arizona Catherine Scudieri, School of Forestry, Northern Arizona University, Flagstaff, AZ, USFS, Rocky Mountain Research Station, Flagstaff, AZ; James F. Fowler, Carolyn Hull Sieg, USFS, Rocky Mountain Research Station, Flagstaff, AZ; Laura Williams, Department of Biological Sciences, Northern Arizona University, Flagstaff, AZ; and Sally M. Haase, USFS, Pacific Southwest Research Station, Riverside, CA Abstract—This paper presents a vascular plant species list for two sites that are part of a long-term study exploring the effects of varying fire intervals on forest characteristics includ- ing the abundance and composition of understory vegetation. The Chimney Spring study area is on the Fort Valley Experimental Forest near Flagstaff, AZ, and the Limestone Flats study area is on the Long Valley Experimental Forest, 90 km (56 mi) southeast of Flagstaff. Since 1976 (Chimney Spring) and 1977 (Limestone Flats), three replicates of each of seven burn intervals (1, 2, 4, 6, 8, 10 years, plus unburned) have been maintained by the USFS Pacific Southwest Research Station. Each study area encompasses approximately 40 to 48 ha (99 to 119 acres) of dense ponderosa pine (Pinus ponderosa) forest. Our plant species list was generated through systematic sampling of the understory vegetation in 2006 and 2007 as well as surveys of the entire study areas for additional species. We documented a total of 147 species, with 96 species found at Chimney Spring and 123 species at Limestone Flats. There are eight introduced species on the list, with six introduced species found at Chimney Spring and seven found at Limestone Flats. -

An Illustrated Key to the Ferns of Oregon
AN ABSTRACT OF THE THESIS OF Helen Patricia O'Donahue Pembrook for the Master of Arts (Name) (Degree) Systematic Botany (Major) Date thesis is presented March 8, 1963 Title AN ILLUSTRATED KEY TO THE FERNS OF OREGON Abstract approved IIIII (Major professor) The purpose of the work is to enable students of botany to identify accurately Oregon ferns, both as living plants and as dried speci- mens. Therefore, it provides vegetative keys to the families, genera and species of the ferns (Class FILICINAE) found in Oregon. Correct names have been determined using the latest available information and in accordance with 1961 edition of the International Code of Botan- ical Nomenclature. The synonomy, a description, and original draw- ings of each species and subspecific taxon are included. An illustrated glossary and a technical glossary have been prepared to explain and clarify the descriptive terms used. There is also a bibliography of the literature used in the preparation of the paper. The class FILICINAE is represented in Oregon by 4 families, 20 genera, 45 or 46 species, 4 of which are represented by more than one subspecies or variety. One species, Botrychium pumicola Coville, is endemic. The taxa are distributed as follows: OPHIO- GLOSSACEAE, 2 genera: Botrychium, 7 species, 1 represented by 2 subspecies, 1 by 2 varieties; Ophioglossum, 1 species. POLYPODI- ACEAE, 15 genera: Woodsia., 2 species; Cystopteris, 1 species; Dryopteris, 6 species; Polystichum, 5 species, 1 represented by 2 distinct varieties; Athyrium, 2 species; Asplenium, 2 species; Stru- thiopteris, 1 species; Woodwardia, 1 species; Pitrogramma, 1 spe- cies; Pellaea, 4 species; Cheilanthes, 3 or 4 species; Cryptogramma, 1 species; Adiantum, 2 species; Pteridium, 1 species; Polypodium, 2 species, 1 represented by 2 varieties. -
WETLAND PLANTS – Full Species List (English) RECORDING FORM
WETLAND PLANTS – full species list (English) RECORDING FORM Surveyor Name(s) Pond name Date e.g. John Smith (if known) Square: 4 fig grid reference Pond: 8 fig grid ref e.g. SP1243 (see your map) e.g. SP 1235 4325 (see your map) METHOD: wetland plants (full species list) survey Survey a single Focal Pond in each 1km square Aim: To assess pond quality and conservation value using plants, by recording all wetland plant species present within the pond’s outer boundary. How: Identify the outer boundary of the pond. This is the ‘line’ marking the pond’s highest yearly water levels (usually in early spring). It will probably not be the current water level of the pond, but should be evident from the extent of wetland vegetation (for example a ring of rushes growing at the pond’s outer edge), or other clues such as water-line marks on tree trunks or stones. Within the outer boundary, search all the dry and shallow areas of the pond that are accessible. Survey deeper areas with a net or grapnel hook. Record wetland plants found by crossing through the names on this sheet. You don’t need to record terrestrial species. For each species record its approximate abundance as a percentage of the pond’s surface area. Where few plants are present, record as ‘<1%’. If you are not completely confident in your species identification put’?’ by the species name. If you are really unsure put ‘??’.

Mississippi Natural Heritage Program Special Plants - Tracking List -2018
MISSISSIPPI NATURAL HERITAGE PROGRAM SPECIAL PLANTS - TRACKING LIST -2018- Approximately 3300 species of vascular plants (fern, gymnosperms, and angiosperms), and numerous non-vascular plants may be found in Mississippi. Many of these are quite common. Some, however, are known or suspected to occur in low numbers; these are designated as species of special concern, and are listed below. There are 495 special concern plants, which include 4 non- vascular plants, 28 ferns and fern allies, 4 gymnosperms, and 459 angiosperms 244 dicots and 215 monocots. An additional 100 species are designated “watch” status (see “Special Plants - Watch List”) with the potential of becoming species of special concern and include 2 fern and fern allies, 54 dicots and 44 monocots. This list is designated for the primary purposes of : 1) in environmental assessments, “flagging” of sensitive species that may be negatively affected by proposed actions; 2) determination of protection priorities of natural areas that contain such species; and 3) determination of priorities of inventory and protection for these plants, including the proposed listing of species for federal protection.

RESOLVING THE ANOMALY OF LOMATIUM ANOMALUM: DISCOVERY OF A NEW SPECIES IN SOUTHWESTERN IDAHO (U.S.A.), LOMATIUM ANDRUSIANUM (APIACEAE) Mckayla Stevens, Donald H. Mansfield James F. Smith The College of Idaho Boise State University 2112 Cleveland Blvd. 1910 W. University Drive Caldwell, Idaho 83605, U.S.A. Boise, Idaho 83725, U.S.A. Mary Ann E. Feist University of Wisconsin-Madison 430 Lincoln Drive Madison, Wisconsin 53706, U.S.A. ABSTRACT Apparent polyphyly within the unresolved clade of Lomatium (Apiaceae) containing L. triternatum, L. anomalum, L. thompsonii, and L. pack- ardiae suggests conflict among current taxonomic classification schemes. To recover this clade and more clearly define species boundaries, we examined populations of L. anomalum from three geographic regions in Idaho and adjacent Oregon. Using phylogenetic, morphological, and ecological data, we conclude that the L. anomalum complex currently circumscribes multiple species. Phylogenetic analysis of the nuclear ribosomal ITS and ETS, and cpDNA rpl32-trnLUAG, rps-16 intron, trnD-trnT, ndhA intron, and psbA-trnH recovered populations from the Boise foothills as a distinct, monophyletic clade. Principal Components Analysis of 30 reproductive and vegetative characters show two distinct groups: one of Boise foothills and one of the combined Mann Creek and Camas Prairie vicinities. Principal Components Analysis of 16 soil characteristics show that soils occupied by Boise foothills populations are distinct from those occupied by Mann Creek and Camas Prairie populations. Based on phylogenetic, morphometric, and ecologic criteria, populations of what had been considered L. anomalum from the Boise foothills and vicinity are here described as a new species—Lomatium andrusianum. -

The Problems. t is a well-known fact that rainy weather may have a very I injurious effect on many flowers. The fructification becomes poor and many flowers may be completely ruined during showers of rain because petals are beaten off, stamens and styles rot, and pollen is spoilt and washed away while at the same time visits by insects are prevented. In nature finer flowers (e. g. those of grasses) may be injured by rain in a similar way as flowers in gardens. In the literature there is plenty of information about such structural features as serve to protect flowers from the injurious influence of rain. All these questions forced themselves upon me during a year’s stay in the Faroes (1922—23), where it is raining—little or much— on most of the days of the year. I have even witnessed that it has been raining incessantly there for five days running. -
Lomatium Ravenii Var. Paiutense and Lomatium Bentonitum Donald H
Th e Discovery of Two New Tufted Desertparsleys from Southeastern Oregon: Lomatium ravenii var. paiutense and Lomatium bentonitum Donald H. Mansfi eld Department of Biology, Th e College of Idaho Caldwell, Idaho 83605 nyone who has ever tried to identify a biscuitroot or desertparsley (Lomatium) Aor springparsley (Cymopterus) can ap- preciate how variable these plants can be. As a consequence of my fl oristic study of southeast- ern Oregon, most recently the Owyhee region, I often encounter unusual forms of plants. Sometimes these forms are just minor variations within the range of what might be expected for a given species, and other times the variations seem diff erent enough to warrant a closer look. Further investigation may include more fi eld observations, locating additional populations with the unusual characters, careful measure- ments and comparisons of these characters between closely related species, greenhouse or experimental manipulations, or even phyloge- netic analysis of DNA sequence data. At the small liberal arts college where I teach, some of these aberrant populations that “don’t read the books” make for fun research projects for keen undergraduate students. Th at was the case in the mid-2000s when I suggested to my student, Kim Carlson, that she make some measurements on specimens of three species of Lomatium from southeastern Oregon and southwestern Idaho. Flowers in these “apioids” (Apiaceae, the carrot and parsley family) are small and rather nondescript white, yellow, or sometimes purplish, reddish, or brownish- green. Easily recognized by the characteristic umbel, members of the genera Lomatium Figure 1.
