    April 26, 2019 Theodore Payne Foundation’s Wild Flower Hotline is made possible by donations, memberships, and the generous support of S&S Seeds. Now is the time to really get out and hike the trails searching for late bloomers. It’s always good to call or check the location’s website if you can, and adjust your expectations accordingly before heading out. Please enjoy your outing, and please use your best flower viewing etiquette. Along Salt Creek near the southern entrance to Sequoia National Park, the wildflowers are abundant and showy. Masses of spring flowering common madia (Madia elegans) are covering sunny slopes and bird’s-eye gilia (Gilia tricolor) is abundant on flatlands. Good crops of owl’s clover (Castilleja sp.) are common in scattered colonies and along shadier trails, woodland star flower (Lithophragma sp.), Munz’s iris (Iris munzii), and the elegant naked broomrape (Orobanche uniflora) are blooming. There is an abundance of Chinese houses (Collinsia heterophylla) and foothill sunburst (Pseudobahia heermanii). This is a banner year for the local geophytes. Mountain pretty face (Tritelia ixiodes ssp. anilina) and Ithuriel’s spear (Triteliea laxa) are abundant. With the warming temperatures farewell to spring (Clarkia cylindrical subsp. clavicarpa) is starting to show up with their lovely bright purple pink floral display and is particularly noticeable along highway 198. Naked broom rape (Orobanche uniflora), foothill sunburst (Pseudobahia heermanii). Photos by Michael Wall © Theodore Payne Foundation for Wild Flowers & Native Plants, Inc. No reproduction of any kind without written permission. The trails in Pinnacles National Park have their own personality reflecting the unusual blooms found along them.

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

  • © 2020 Theodore Payne Foundation for Wild Flowers & Native Plants. No
    May 8, 2020 Theodore Payne Foundation’s Wild Flower Hotline is made possible by donations, memberships and sponsors. You can support TPF by shopping the online gift store as well. A new, pay by phone, contactless plant pickup system is now available. Details here. Widespread closures remain in place. If you find an accessible trail, please practice social distancing. The purpose for the Wild Flower Hotline now is NOT to send you to localities for wild flower viewing, but to post photos that assure you—virtually—that California’s wild spaces are still open for business for flowers and their pollinators. LA County’s Wildlife Sanctuaries are starting to dry up from the heat. This may be the last week to see flowers at Jackrabbit Flats and Theodore Payne Wildlife Sanctuaries near Littlerock in the high desert. Yellow is the dominant color with some pink and white scattered about. Parry’s linanthus (Linanthus parryae) and Bigelow’s coreopsis (Leptosyne bigelovii), are widespread. Small patches of goldfields (Lasthenia californica), and Mojave sun cups (Camissonia campestris) are still around. If you are visiting around dusk, the evening snow (Linanthus dichotomus) open up and put on a display that lives up to its name. Strewn around are Pringle’s woolly sunflower (Eriophyllum pringlei), white tidy tips (Layia glandulosa), owl’s clover (Castilleja sp.) and desert dandelion (Malacothrix glabrata). Underneath the creosote bushes, lacy phacelia (Phacelia tanacetifolia) is seeking out some shade. Theodore Payne Sanctuary has all these flowers, and because it has more patches of sandy alluvial soils, has some cute little belly flowers like Wallace’s wooly daisy (Eriophyllum wallacei) and purple mat (Nama demissa) too.

  • Nomenclature of the Main Subdivisions of Phlox (Polemoniaceae)
    NUMBER 4 GRANT: PHLOX NOMENCLATURE 25 NOMENCLATURE OF THE MAIN SUBDIVISIONS OF PHLOX (POLEMONIACEAE) Verne Grant Section of Integrative Biology and Plant Resources Center, The University of Texas, Austin, Texas 78712 Abstract: The task of finding the correct names for the main subdivisions of Phlox has been beset with difficulties in interpreting the intent of older authors, particularly Asa Gray. Gray divided Phlox into four main subgroups, some of which have been considered sections, but these are now seen to be only informal groups. Currently Phlox is subdivided into three sections: Phlox, Divaricatae Peter, and Occidentales A. Gray. The name Occidentales A. Gray was not validly published as a section; Gray used it only as part of a heading. The oldest valid name for what has been called sect. Occidentales is sect. Pulvinatae Peter. Recent papers have used the name sect. Annuae A. Gray in place of sect. Divaricatae, on grounds of priority. However, the name that Gray actually used was Annuae, Texenses, and it, like Occidentales, was not validly published. The sections of Phlox are being reconsidered at present in the light of new molecular evidence. Some changes will be needed, but old valid infra­ generic names will still have a role to play in new infrageneric classifications. Keywords: Phlox, nomenclature, Asa Gray. The genus Phlox has had a history of terms subgenus and section in the nine­ problems with the nomenclature of the teenth century. Some authors used the cat­ main infrageneric subgroups. Gray (1870, egory subgenus, others the category section, 1878, 1886) did not make it clear in his still others used both, or neither.

  • Palouse Forbs for Landscaping
    More Palouse Forbs for Landscaping. by David M. Skinner, Paul Warnick, Bill French, and Mary Fauci November, 2005 The following is an additional list of native forbs which may be found in the Palouse region. These forbs may be less suitable for the landscape because of growth habit, aggressiveness, difficulty in propagating and growing, rarity, or it simply may be that we haven’t yet tried to do anything with them. For a list of Palouse forbs which may be more suitable for landscaping and about which we have more information to share, please see “Characteristics and Uses of Native Palouse Forbs in Landscaping.” Nomenclature used in this document also follows Hitchcock, C. Leo, and Arthur Cronquist. 1973. Flora of the Pacific Northwest. Univ. of Washington Press. Seattle, WA. In order to facilitate searching for a particular species, we have included some common names and alternate scientific names, but this is by no means intended to be a comprehensive source of common names or synonyms. Detailed information on propagation of many native species can be found at <http://nativeplants.for.uidaho.edu/network/search.asp?SearchType=Continental> Agastache urticifolia is probably too large a plant for a small garden. Requires a moist site. Easy to grow from seed. Plants have a minty smell and a very interesting flower. Common names include nettle-leafed giant hyssop, horsemint. Agoseris grandiflora is not a particularly attractive plant, it looks rather like a weed. Short-lived and attracts rodents, which eat the taproot and kill the plants. Easy to grow from seed, which is wind-borne and goes everywhere.

  • Chromosome Numbers in the Polemoniaceae Representatives Of
    1937 171 Chromosome Numbers in the Polemoniaceae By Walter S. Flory Division of Horticulture, Texas Agricultural Experiment Station This family is divided by systematists into two subfamilies. Cobaeoideae is composed of the genera Cantua, Huthia, and Cobaea which are tall shrubs, trees, or vines. The approximately fourteen other (herbaceous or low shrubby) genera comprise the subfamily Polemonioideae. From the standpoint of number of included species the most important of these latter genera are Gilia, Phlox, Polemo nium, and Collomia. The genera Phlox and Polemonium are each quite distinct and their species are seldom confused with those of other genera, but the remaining twelve genera of this subfamily apparently do not have taxonomic boundaries of equivalent distinctness. Certain species have been placed in one genus by one author, and in one or more different genera by others. The genus Gilia has been ex tended by some writers to include practically all species of the Polemonioideae outside of the genera Phlox and Polemonium. This was first pointed out to me by Professor Edgar T. Wherry who is making a taxonomic and geographic study of the Polemoniaceae, and was increasingly emphasized as literature sources and herbarium specimens were consulted and examined. It has been the purpose of the work herein presented to secure data on all obtainable polemoniaceous species with respect to chro mosome numbers, size, and general morphology. Especial attention has been given to securing information of significance from a taxono mic standpoint. Since several factors combine to make the immedi ate completion of the original program impossible it seems desirable, meanwhile, to present the accumulated data, together with suggested conclusions.

  • Survey and Analysis of Plant Community Types of Writing-On-Stone Provincial Park
    Survey and Analysis of Plant Community Types of Writing-on-Stone Provincial Park Survey and Analysis of Plant Community Types of Writing-on-Stone Provincial Park FINAL REPORT Prepared for Alberta Sustainable Resource Development Resource Data Branch Edmonton, Alberta Prepared by Wildlands Ecological Consulting Ltd. #60 Neal Close, Red Deer, AB T4P 1N4 Office: (403) 346-1057 Fax: (403) 346-3257 March 29, 2004 ABSTRACT Identification and monitoring of biological diversity in Alberta is the primary mandate of Alberta Natural Heritage Information Centre (ANHIC). A fundamental strategy in the preservation of functional ecosystems is to identify and preserve a full compliment of habitat types, which in return support a diversity of animals, plants, and other life forms. Vegetation is an integral component of habitat and provides a relatively easy means of inventory and monitoring of ecosystem health both spatially and temporally. The current study, in Writing-on-Stone Provincial Park, focuses on the identification of unique riparian and coulee plant associations, or plant community type. The study area is situated approximately 8 km north of the USA border and 40 km east of the town of Milk River and occurs at the interface between the Mixedgrass and Dry Mixedgrass Natural Subregions. Priority research is currently required to address gaps in the identification, description and distribution of plant associations within the coulee and riparian zones of these Subregions. Many of these communities recur over the landscape but may occur as very small patches of 1m2 or less. Alberta Sustainable Resource Development (ASRD) Resource Data Division contracted Wildlands Ecological to complete an inventory of natural/semi-natural plant communities, statistically analyse the data, and describe potential plant community or association types.

Hooker was so impressed with the young Scot that for“P myself some 70 years later. With grants from the Native he recommended Douglas to the Royal Horticultural Society of Plant Society of Oregon and the North American Rock Garden London as a botanical collector (Hooker 1836).
