Aquilegia Magazine of the Colorado Native Plant Society Volume 44 No. 1 Winter 2020 Aquilegia Volume 44 No. 1 Winter 2020 www.CoNPS.org 1 Mountain Ninebark, Physocarpus monogynus (Rosaceae). This shrub is common in elevations of 4,800-10,500’, generally in partially to fully shaded areas. It may be confused with Ribes sp. A key characteristic of the plant is the peeling bark of the older stems, which helps with identification even in the winter. In the summer, the white flowers are arranged in corymbs, with exerted stamens. In winter, the browned flowers usually remain attached to the stems. Leaves are palmately lobed and conspicuously veined. This is an attractive shrub for shady gardens. The flowers are a valuable source of nectar for native pollinators, particularly bees, and provide good cover for birds. Some American Indian tribes made a pain-relieving poultice by boiling the roots and placing the warmed plant material on the affected site. KA Map adapted from Ackerfield, J.

    P L a N T L I S T Water-Wise Trees and Shrubs for the High Plains

    P L A N T L I S T Water-Wise Trees and Shrubs for the High Plains By Steve Scott, Cheyenne Botanic Gardens Horticulturist 03302004 © Cheyenne Botanic Gardens 2003 710 S. Lions Park Dr., Cheyenne WY, 82001 www.botanic.org The following is a list of suitable water-wise trees and shrubs that are suitable for water- wise landscaping also known as xeriscapes. Many of these plants may suffer if they are placed in areas receiving more than ¾ of an inch of water per week in summer. Even drought tolerant trees and shrubs are doomed to failure if grasses or weeds are growing directly under and around the plant, especially during the first few years. It is best to practice tillage, hoeing, hand pulling or an approved herbicide to kill all competing vegetation for the first five to eight years of establishment. Avoid sweetening the planting hole with manure or compost. If the soil is needs improvement, improve the whole area, not just the planting hole. Trees and shrubs generally do best well with no amendments. Many of the plants listed here are not available in department type stores. Your best bets for finding these plants will be in local nurseries- shop your hometown first! Take this list with you. Encourage nurseries and landscapers to carry these plants! For more information on any of these plants please contact the Cheyenne Botanic Gardens (307-637-6458), the Cheyenne Forestry Department (307-637-6428) or your favorite local nursery.

The rancid odor of Arilus and other reduviids actually comes from Brindley's glands, which in the North (A. cristatus) and South (A. carinatus) American wheel bugs studied emit similar blends of 2-methylpropanoic, butanoic, 3-methylbutanoic, and 2-methylbutanoic acids.

    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.

Hazlett, Michael H. Schiebout, and Paulette L. Ford Hazlett, Donald L.; Schiebout, Michael H.; and Ford, Paulette L. 2009. Vascular plants and a brief history of the Kiowa and Rita Blanca National Grasslands. Gen. Tech. Rep. RMRS- GTR-233. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 44 p. Abstract Administered by the USDA Forest Service, the Kiowa and Rita Blanca National Grasslands occupy 230,000 acres of public land extending from northeastern New Mexico into the panhandles of Oklahoma and Texas. A mosaic of topographic features including canyons, plateaus, rolling grasslands and outcrops supports a diverse flora. Eight hundred twenty six (826) species of vascular plant species representing 81 plant families are known to occur on or near these public lands. This report includes a history of the area; ethnobotanical information; an introductory overview of the area including its climate, geology, vegetation, habitats, fauna, and ecological history; and a plant survey and information about the rare, poisonous, and exotic species from the area. A vascular plant checklist of 816 vascular plant taxa in the appendix includes scientific and common names, habitat types, and general distribution data for each species. This list is based on extensive plant collections and available herbarium collections. Authors Donald L. Hazlett is an ethnobotanist, Director of New World Plants and People consulting, and a research associate at the Denver Botanic Gardens, Denver, CO.

Baum Thesis Adviser Dr. Karen R. Hickman Dr. Dwayne Elmore ii ACKNOWLEDGEMENTS I would like to begin by thanking my advisor, Dr. Kristen Baum, for all of her guidance and expertise throughout this research project. She is an exemplary person to work with, and I am so grateful to have shared my graduate school experience with her. I would also like to recognize my committee members, Dr. Karen Hickman and Dr. Dwayne Elmore, both of whom provided valuable insight to this project. A huge thank you goes out to the Southern Plains Network of the National Park Service, specifically Robert Bennetts and Tomye Folts-Zettner. Without them, this project would not exist, and I am forever grateful to have been involved with their network and parks, both as a research student and summer crew member. A special thank you for Jonathin Horsely, who helped with plot selection, summer sampling, and getting my gear around. I would also like to thank the Baum Lab members, always offering their support and guidance as we navigated through graduate school. And lastly, I would like to thank my family, especially my fiancé Garrett, for believing in me and supporting me as I pursued my goals.
