  • Alplains 2013 Seed Catalog P.O
    ALPLAINS 2013 SEED CATALOG P.O. BOX 489, KIOWA, CO 80117-0489, U.S.A. Three ways to contact us: FAX: (303) 621-2864 (24 HRS.) email: [email protected] website: www.alplains.com Dear Growing Friends: Welcome to our 23rd annual seed catalog! The summer of 2012 was long, hot and brutal, with drought afflicting most of the U.S. Most of my botanical explorations were restricted to Idaho, Wash- ington, Oregon and northern California but even there moisture was below average. In a year like this, seeps, swales, springs, vestigial snowbanks and localized rainstorms became much more important in my search for seeding plants. On the Snake River Plains of southern Idaho and the scab- lands of eastern Washington, early bloomers such as Viola beckwithii, V. trinervata, Ranunculus glaberrimus, Ranunculus andersonii, Fritillaria pudica and Primula cusickiana put on quite a show in mid-April but many populations could not set seed. In northern Idaho, Erythronium idahoense flowered extensively, whole meadows were covered with thousands of the creamy, pendant blossoms. One of my most satisfying finds in the Hells Canyon area had to be Sedum valens. The tiny glaucous rosettes, surround- ed by a ring of red leaves, are a succulent connoisseur’s dream. Higher up, the brilliant blue spikes of Synthyris missurica punctuated the canyon walls. In southern Oregon, the brilliant red spikes of Pedicularis densiflora lit up the Siskiyou forest floor. Further north in Oregon, large populations of Erythronium elegans, Erythronium oregonum ssp. leucandrum, Erythro- nium revolutum, trilliums and sedums provided wonderful picture-taking opportunities. Eriogonum species did well despite the drought, many of them true xerics.

  • Germination and Seedling Establishment of Spiny Hopsage (Grayia Spinosa [Hook.] Moq.)
    AN ABSTRACT OF THE THESIS OF Nancy L. Shaw for the degree of Doctor of Philosophy in Crop and Soil Sciences presented on March 19, 1992 Title: Germination and Seedling Establishment of Spiny Hopsage (Grayia Spinosa [Hook.] Moq.) Abstract approved:_Redactedfor Privacy von r. ULdUe Reestablishment of spiny hopsage(Grayia spinosa [Hook.] Moq.) where depleted or lost on shrub steppe sites can improve forage, plant cover, and soil stabilization. The objectives of this study were to: 1) determine direct-seeding requirements; 2) develop optimum germination pretreatments; and 3) examine dormancy mechanisms in spiny hopsage fruits and seeds. The effects of seed source, planting date,and site preparation method onseed germination and seedling establishment (SE) were examined at Birds of Prey and Reynolds Creek in southwestern Idaho. Three seed sources were planted on rough or compact seedbeds on 4 dates in 1986-87 and 3 dates in 1987-88. Exposure to cool-moist environments improved spring SE from early fall (EF) and late fall (LF) plantings. Few seedlings emerged from early (ESp) or late spring (LSp) plantings. SE was low at: 1 site in 1986-87 and atboth sites in 1987-88, probably due to lack of precipitation. For the successful 1986-87 planting, seedling density was greater on rough compared to compact seedbeds in April andMay, possiblydue to improved microclimate conditions. Growth rate varied among seed sources, but seedlings developed a deep taproot (mean length 266 mm) with few lateral roots the first season. Seeds were planted on 3 dates in 1986-87 and 1987-88, andnylon bags containing seeds were planted on 4 dates each year to study microenvironment effects on germination (G), germination rate (GR), and SE.

  • CDFG Natural Communities List
    Department of Fish and Game Biogeographic Data Branch The Vegetation Classification and Mapping Program List of California Terrestrial Natural Communities Recognized by The California Natural Diversity Database September 2003 Edition Introduction: This document supersedes all other lists of terrestrial natural communities developed by the Natural Diversity Database (CNDDB). It is based on the classification put forth in “A Manual of California Vegetation” (Sawyer and Keeler-Wolf 1995 and upcoming new edition). However, it is structured to be compatible with previous CNDDB lists (e.g., Holland 1986). For those familiar with the Holland numerical coding system you will see a general similarity in the upper levels of the hierarchy. You will also see a greater detail at the lower levels of the hierarchy. The numbering system has been modified to incorporate this richer detail. Decimal points have been added to separate major groupings and two additional digits have been added to encompass the finest hierarchal detail. One of the objectives of the Manual of California Vegetation (MCV) was to apply a uniform hierarchical structure to the State’s vegetation types. Quantifiable classification rules were established to define the major floristic groups, called alliances and associations in the National Vegetation Classification (Grossman et al. 1998). In this document, the alliance level is denoted in the center triplet of the coding system and the associations in the right hand pair of numbers to the left of the final decimal. The numbers of the alliance in the center triplet attempt to denote relationships in floristic similarity. For example, the Chamise-Eastwood Manzanita alliance (37.106.00) is more closely related to the Chamise- Cupleaf Ceanothus alliance (37.105.00) than it is to the Chaparral Whitethorn alliance (37.205.00).

  • Chromosome Numbers in Compositae, XII: Heliantheae
    SMITHSONIAN CONTRIBUTIONS TO BOTANY 0 NCTMBER 52 Chromosome Numbers in Compositae, XII: Heliantheae Harold Robinson, A. Michael Powell, Robert M. King, andJames F. Weedin SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Robinson, Harold, A. Michael Powell, Robert M. King, and James F. Weedin. Chromosome Numbers in Compositae, XII: Heliantheae. Smithsonian Contri- butions to Botany, number 52, 28 pages, 3 tables, 1981.-Chromosome reports are provided for 145 populations, including first reports for 33 species and three genera, Garcilassa, Riencourtia, and Helianthopsis. Chromosome numbers are arranged according to Robinson’s recently broadened concept of the Heliantheae, with citations for 212 of the ca. 265 genera and 32 of the 35 subtribes. Diverse elements, including the Ambrosieae, typical Heliantheae, most Helenieae, the Tegeteae, and genera such as Arnica from the Senecioneae, are seen to share a specialized cytological history involving polyploid ancestry. The authors disagree with one another regarding the point at which such polyploidy occurred and on whether subtribes lacking higher numbers, such as the Galinsoginae, share the polyploid ancestry. Numerous examples of aneuploid decrease, secondary polyploidy, and some secondary aneuploid decreases are cited. The Marshalliinae are considered remote from other subtribes and close to the Inuleae. Evidence from related tribes favors an ultimate base of X = 10 for the Heliantheae and at least the subfamily As teroideae.

  • Literature Cited
    Literature Cited Robert W. Kiger, Editor This is a consolidated list of all works cited in volumes 19, 20, and 21, whether as selected references, in text, or in nomenclatural contexts. In citations of articles, both here and in the taxonomic treatments, and also in nomenclatural citations, the titles of serials are rendered in the forms recommended in G. D. R. Bridson and E. R. Smith (1991). When those forms are abbre- viated, as most are, cross references to the corresponding full serial titles are interpolated here alphabetically by abbreviated form. In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”. Works missing from any suffixed sequence here are ones cited elsewhere in the Flora that are not pertinent in these volumes.

  • Notes on the Occurrence of Erigeron Sumatrensis (Asteraceae) in Georgia
    Nesom, G.L. 2018. Notes on the occurrence of Erigeron sumatrensis (Asteraceae) in Georgia. Phytoneuron 2018-66: 1–5. Published 1 October 2018. ISSN 2153 733X NOTES ON THE OCCURRENCE OF ERIGERON SUMATRENSIS (ASTERACEAE) IN GEORGIA GUY L. NESOM 2925 Hartwood Drive Fort Worth, Texas 76109 [email protected] ABSTRACT A survey for Erigeron sumatrensis in central Georgia indicates that it is densely distributed on the the coastal plain there, suggesting that its occurrence may be similar from South Carolina to Louisiana. Vouchers and a distribution map for the Georgia records are provided. A recent study (Nesom 2018) documented the occurrence of Erigeron sumatrensis Retz. across the southeastern USA (Fig. 1). Current herbarium collections suggest that it is common in coastal counties but sporadic in more inland areas. The present report indicates that the species probably is more densely distributed through the coastal plain from South Carolina to Louisiana. On 9-10 September, 2018, I surveyed a broad loop in central Georgia and added 14 county records to the distribution of Erigeron sumatrensis . Figure 2 shows the more geographically saturated distribution the species has attained there. The tall columnar habit (characteristically 4-6 feet tall) of Erigeron sumatrensis makes it conspicuous (Figs. 3-5). In central Georgia I found it along roadsides and fencerows and at edges of cultivated and fallow fields. It is local in occurrence, usually as only 1 or a few plants (but sometimes up to 10-15 in a cluster), often growing with more abundant and continuously distributed E. canadensis . Erigeron sumatrensis in September is at the end of its growing season and mostly in fruit, while many plants of E.
