  • California's Native Ferns
    CALIFORNIA’S NATIVE FERNS A survey of our most common ferns and fern relatives Native ferns come in many sizes and live in many habitats • Besides living in shady woodlands and forests, ferns occur in ponds, by streams, in vernal pools, in rock outcrops, and even in desert mountains • Ferns are identified by producing fiddleheads, the new coiled up fronds, in spring, and • Spring from underground stems called rhizomes, and • Produce spores on the backside of fronds in spore sacs, arranged in clusters called sori (singular sorus) Although ferns belong to families just like other plants, the families are often difficult to identify • Families include the brake-fern family (Pteridaceae), the polypody family (Polypodiaceae), the wood fern family (Dryopteridaceae), the blechnum fern family (Blechnaceae), and several others • We’ll study ferns according to their habitat, starting with species that live in shaded places, then moving on to rock ferns, and finally water ferns Ferns from moist shade such as redwood forests are sometimes evergreen, but also often winter dormant. Here you see the evergreen sword fern Polystichum munitum Note that sword fern has once-divided fronds. Other features include swordlike pinnae and round sori Sword fern forms a handsome coarse ground cover under redwoods and other coastal conifers A sword fern relative, Dudley’s shield fern (Polystichum dudleyi) differs by having twice-divided pinnae. Details of the sori are similar to sword fern Deer fern, Blechnum spicant, is a smaller fern than sword fern, living in constantly moist habitats Deer fern is identified by having separate and different looking sterile fronds and fertile fronds as seen in the previous image.

  • NATIVE PLANT FIELD GUIDE Revised March 2012
    NATIVE PLANT FIELD GUIDE Revised March 2012 Hansen's Northwest Native Plant Database www.nwplants.com Foreword Once upon a time, there was a very kind older gentleman who loved native plants. He lived in the Pacific northwest, so plants from this area were his focus. As a young lad, his grandfather showed him flowers and bushes and trees, the sweet taste of huckleberries and strawberries, the smell of Giant Sequoias, Incense Cedars, Junipers, pines and fir trees. He saw hummingbirds poking Honeysuckles and Columbines. He wandered the woods and discovered trillium. When he grew up, he still loved native plants--they were his passion. He built a garden of natives and then built a nursery so he could grow lots of plants and teach gardeners about them. He knew that alien plants and hybrids did not usually live peacefully with natives. In fact, most of them are fierce enemies, not well behaved, indeed, they crowd out and overtake natives. He wanted to share his information so he built a website. It had a front page, a page of plants on sale, and a page on how to plant natives. But he wanted more, lots more. So he asked for help. I volunteered and he began describing what he wanted his website to do, what it should look like, what it should say. He shared with me his dream of making his website so full of information, so inspiring, so educational that it would be the most important source of native plant lore on the internet, serving the entire world.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

  • Corydalis Incisa (Fumariaceae) in Bronx and Westchester Counties, New York

CORYDALIS INCISA (FUMARIACEAE) IN BRONX AND WESTCHESTER COUNTIES, NEW YORK DANIEL ATHA and JESSICA A. SCHULER The New York Botanical Garden Bronx, New York 10458 [email protected] SARAH LUMBAN TOBING NYC Parks Arsenal North 1234 Fifth Avenue, Room 229 New York, New York 10029 ABSTRACT Spontaneously growing plants of the East Asian Corydalis incisa (Thunb.) Pers. (Fumariaceae) are reported from Westchester Co., New York, for the first time. The species was previously only known from a small area along the Bronx River in Bronx Co., New York. The Westchester County plants documented here represent the second known wild population in North America. This discovery increases the number of Corydalis species in North America from ten to eleven and from four to five in the northeastern USA. It is the only spontaneous, purple- or white- flowered species in the Northeast. Corydalis incisa (Thunb.) Pers growing outside of cultivation in North America were first discovered on the floodplain of the Bronx River, near the Burke Avenue Bridge in Bronx Park, New York, by Michael Sundue during the 2005 Bronx River BioBlitz (Sundue, pers. comm). No voucher specimens were collected. Soon after, Steve Glenn collected the species at the same locality and noted "dozens" of individuals along both banks of the River, reported for the first time as naturalized in North America by Lamont et al. (2011). The population has since persisted and expanded. In 2014, a second population was discovered by the authors and is detailed below.

  • 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. OFFICIALPUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution’s annual report, Smithsonian Year.
