Governor General of Canada / Gouverneure générale du Canada On the inside / À l'intérieur I President's Message The past year has been a relatively uneventful one for the CBA President. Letters Page 30 were written on behalf of CBA to NSERC, concerning plant systematics members in grant Editors / La rédaction selection committes, and to the Smithsonian Instutution concerning changes in their CBA Section and Committee Chairs research focus in tropical ecosystems. Letters written by the chair of the Conservation Committee were endorsed and sent to various parties in PE.I concerning proposed changes to a local National Park, and in Newfoundland, concerning a proposed incinerator and its possible effect on a rare lichen.

There is one Congrès annuel de l'ABC 2001 Lawson nomination which will be carried over to next year for consideration. New nomi- nations should be sent to me, if possible, by the end of January 2002. Requirements for sub- mission of nominations for either the Lawson Medal or the Elliott Award will be found on the CBA website. Page 32 The George Lawson Medal The highlight of the year, as it always is, was the Annual Meeting, held this year The Mary E. Elliot Medal at Okanagan University College in Kelowna, BC. Everyone I have spoken to or have received comments from agreed that this was one of the most well organized and enjoyable Annual Meetings we have had. On behalf of all who attended, I want to thank Melanie Jones and all of the people on the local organizing committee for being such great hosts. I am Page 33 glad, however, that I don't have to hike up that hill to the student residences any more (OUC 2001 Award Winners students must be REALLY fit!!). We look forward now to the 2002 Annual Meeting, which will be one of our pe- Page 34 riodic joint meetings with the Botanical Society of America. Also meeting at the same time Poorly Known Economic Plants of Canada - 30. will be the American Fern Society, American Society of Plant Taxonomists, and the Butternut (Juglans cinerea) and black walnut Phycological Society of America. Both Jean and I attended the BSA Annual Meeting at (J. nigra) Albuquerque, New Mexico, where we were brought up-to-date on preparations for the 2002 Meeting. The Meeting will be held at the Pyle Center on the campus of the University of Wisconsin, Madison, August 3-7, 2002. At our Annual Meeting in Kelowna the CBA Page 40 Executive chose Jean Gerrath, University of Northern Iowa, as our "local" representative CBA Board of Directors / and Vice President. She has been active in committees of the BSA during the last few years and already knows many of the people with whom she will interact during the preparations Burcau de direction de l'ABC for the 2002 meeting.

State Street, West Lafayette, IN, 47907 Introduction Butternut (Juglans cinerea), also known as white wal- nut, is a native hardwood related to black walnut (Juglans nigra) and other members of the walnut family. Butternut is a medium-sized tree with alternate, pinnately com- pound leaves, that bears large, sharply ridged, cylindrical nuts inside sticky green hulls that earned it the nickname lemon-nut (Rink, 1990). The nuts, a preferred food of squirrels and other wildlife, were collected and eaten by Native Americans (Waugh, 1916; Hamel and Chiltoskey, 1975) and early settlers, who also valued butternut for its workable, medium brown-colored heartwood (Kel- logg, 1919), and as a source of medicine (Johnson, 1884; Lawrence, 1998), dyes (Hamel and Chiltoskey, 1975), and sap sugar. Butternut’s native range extends over the entire north- eastern quarter of the United States, including many states immediately west of the Mississippi River. Butter- nut is more cold-tolerant than black walnut, and it grows as far north as the Upper Peninsula of Michigan, New Brunswick, southern Quebec, and Ontario (Fig.1).

Year-round . (note: some plants have more than one part that is edible, and depending on what is being harvested may determine when that harvesting period is) TREES The wood of many native trees (especially oak) can be used to age beer on, whether it be barrels or cuttings. Woods can also be used to smoke the beers/malts as well. Eastern Hemlock (Tsuga Canadensis): Needles and young twigs can be brewed into a tea or added as ingredients in cooking, similar flavoring to spruce. Tamarack (Larix laricina): Bark and twigs can be brewed into a tea with a green, earthy flavor. Pine species (Pinus strobus, Pinus banksiana, Pinus virginiana): all pine species have needles that can be made into tea, all similar flavor. Eastern Red Cedar (Juniperus virginiana): mature, dark blue berries and young twigs may be made into tea or cooked with, similar in flavor to most other evergreen species. Pawpaw (Asimina triloba): edible fruit, often described as a mango/banana flavor hybrid. Sassafras (Sassafras albidum): root used to make tea, formerly used to make rootbeer. Similarly flavored, but much more earthy and bitter. Leaves have a spicier, lemony taste and young leaves are sometimes used in salads. Leaves are also dried and included in file powder, common in Cajun and Creole cooking. Northern Hackberry (Celtis occidentalis): Ripe, purple-brown fruits are edible and sweet. Red Mulberry (Morus rubra): mature red-purple-black fruit is sweet and juicy.

  • Juglandaceae (Walnuts)
    A start for archaeological Nutters: some edible nuts for archaeologists. By Dorian Q Fuller 24.10.2007 Institute of Archaeology, University College London A “nut” is an edible hard seed, which occurs as a single seed contained in a tough or fibrous pericarp or endocarp. But there are numerous kinds of “nuts” to do not behave according to this anatomical definition (see “nut-alikes” below). Only some major categories of nuts will be treated here, by taxonomic family, selected due to there ethnographic importance or archaeological visibility.

    Persoonia 38, 2017: 136–155 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/003158517X694768 Juglanconis gen. nov. on Juglandaceae, and the new family Juglanconidaceae (Diaporthales) H. Voglmayr1, L.A. Castlebury2, W.M. Jaklitsch1,3 Key words Abstract Molecular phylogenetic analyses of ITS-LSU rDNA sequence data demonstrate that Melanconis species occurring on Juglandaceae are phylogenetically distinct from Melanconis s.str., and therefore the new genus Juglan- Ascomycota conis is described. Morphologically, the genus Juglanconis differs from Melanconis by light to dark brown conidia with Diaporthales irregular verrucae on the inner surface of the conidial wall, while in Melanconis s.str. they are smooth. Juglanconis molecular phylogeny forms a separate clade not affiliated with a described family of Diaporthales, and the family Juglanconidaceae is new species introduced to accommodate it. Data of macro- and microscopic morphology and phylogenetic multilocus analyses pathogen of partial nuSSU-ITS-LSU rDNA, cal, his, ms204, rpb1, rpb2, tef1 and tub2 sequences revealed four distinct species systematics of Juglanconis. Comparison of the markers revealed that tef1 introns are the best performing markers for species delimitation, followed by cal, ms204 and tub2. The ITS, which is the primary barcoding locus for fungi, is amongst the poorest performing markers analysed, due to the comparatively low number of informative characters. Melanconium juglandinum (= Melanconis carthusiana), M. oblongum (= Melanconis juglandis) and M. pterocaryae are formally combined into Juglanconis, and J. appendiculata is described as a new species. Melanconium juglandinum and Melanconis carthusiana are neotypified and M. oblongum and Diaporthe juglandis are lectotypified. A short descrip- tion and illustrations of the holotype of Melanconium ershadii from Pterocarya fraxinifolia are given, but based on morphology it is not considered to belong to Juglanconis.

  • Juglans Cinerea L
    R E S E A R C H A R T I C L E ABSTRACT: To mitigate the loss of native tree species threatened by non-native pathogens, managers need to better understand the conservation status of remaining populations and the conditions that favor successful regeneration. Populations of Juglans cinerea L. (butternut), a wide-ranging riparian species, • have been devastated by butternut canker, a disease caused by a non-native fungal pathogen. We as- sessed J. cinerea within Great Smoky Mountains National Park (GSMNP) to determine post-disease survivorship and health, recruitment history, environmental conditions associated with survival, and the Conservation Status extent of hybridization with a non-native congener. Monitoring records were used to locate and collect data for 207 J. cinerea trees in 19 watersheds. Tree cores were collected from a subset of individuals to of a Threatened Tree assess recruitment history. We sampled vegetation plots within areas that contained J. cinerea to assess site conditions and overstory species composition of characteristic habitat. We collected leaf samples for Species: Establishing genetic analysis to determine the frequency of hybridization. Our reassessment of monitoring records suggests that J. cinerea abundance in GSMNP has declined due to butternut canker and thirty years of a Baseline for poor regeneration. Populations displayed continuous recruitment following Park establishment (1934) until around 1980, after which regeneration declined drastically. Ordination analysis revealed that J. Restoration of Juglans cinerea in the contemporary forest was associated with greater distance from homesites and reduced basal area of competing species.

  • Vegetative Propagation of Butternut (Juglans Cinerea) Field Results
    Black Walnut in a New Century VEGETATIVE PROPAGATION OF BUTTERNUT (JUGLANS CINEREA) FIELD RESULTS Paula M. Pijut1 ABSTRACT—Juglans cinerea L. is a hardwood species valued for its wood and edible nuts. Butternut canker disease (Sirococcus clavigignenti-juglandacearum) threatens its survival. Vegetative propagation will be required to produce clones of genotypes selected for resistance to butternut canker disease. In 2000, 10 trees were randomly selected from a 6-year-old butternut plantation located in Rosemount, MN. Hardwood stem cuttings were collected in March, April, and May. Softwood cuttings were collected in June and July. Indole-3-butyric acid-potassium salt (K-IBA) at 0, 29, or 62 mM in water and indole-3-butyric acid (IBA) at 0, 34, or 74 mM in 70% ethanol were tested for root induction on cuttings. The basal end of cuttings were dipped in a treatment solution for 10 to 15 s, potted in a peat:perlite mixture and placed in a mist bed for 5 to 8 weeks. Rooted cuttings were gradually hardened off from the mist bed, allowed to initiate new growth, over-wintered in a controlled cold-storage environment, and then outplanted to the field. Rooting was greatest for hardwood cuttings taken in mid-May (branches flushed out), 22% with 62 mM K-IBA and 28% with 74 mM IBA. Softwood cuttings rooted best when taken in June (current season’s first flush of new growth or softwood growth 40 cm or greater) and treated with 62 mM K-IBA (77%) or 74 mM IBA (88%). One-hundred and seventy three (173) out of 186 rooted softwood cuttings (93%) survived over-wintering and acclimatization to the field.
