Don In this year’s Tree of the Year article DOUGLAS JUSTICE writes an account of the western red-cedar or giant arborvitae (tree of life), a species of conifers that, for centuries has been central to the lives of people of the Northwest Coast of America. “In a small clearing in the forest, a young woman is in labour. Two women companions urge her to pull hard on the cedar bark rope tied to a nearby tree. The baby, born onto a newly made cedar bark mat, cries its arrival into the Northwest Coast world. Its cradle of firmly woven cedar root, with a mattress and covering of soft-shredded cedar bark, is ready. The young woman’s husband and his uncle are on the sea in a canoe carved from a single red-cedar log and are using paddles made from knot-free yellow cedar.

Department of forfs't Sci e rt c*5 The University of British Columbia Vancouver, Canada Date April H , 2^003 DE-6 (2/88) Abstract Long-lived woody plants usually show high levels of outcrossing, inbreeding depression and genetic diversity compared to other plants. A review of the literature showed a mean oucrossing rate of 83.5 in conifers, and a positive, but weak, correlation between outcrossing and genetic diversity. Among conifers, western redcedar (Thuja plicata, Cupressaceae) has one of the highest rates of self-fertilization and lowest amount of genetic diversity, and thus offers the opportunity to study the evolution of inbreeding in a predominantly outcrossing group of plants.

  • Identification of Conifer Trees in Iowa This Publication Is Designed to Help Identify the Most Common Trees Found in Iowa
    Identification of Conifer Trees in Iowa This publication is designed to help identify the most common trees found in Iowa. It is based on vegetative characteristics including leaves, fruit, and bark. It is neither complete nor without possible oversights. Separate species are grouped by similar characteristics, mainly based on type and arrangement of leaves. These groups are; awl- or scale- like needles; single needles, flattened with rounded tips; single needles, square in cross section, with pointed tips; and needles in bundles or fasticles of two or more. Remember, vegetative character- istics are quite variable; use more than one specimen for comparison. Awl- or scale-like needles Juniperus Virginiana Eastern Red Cedar Leaves are dark green; leaves are both awl- and scale-like; cone is dark blue and berry-like. Thuja occidentalis Northern White Cedar Leaves are flattened and only of the scale type; cones have 4-6 scales; foliage is light green. Juniperus communis Common Juniper Leaves are awl shaped; cone is dark blue and berry-like. Pm-1383 | May 1996 Single needles, flattened with rounded tips Pseudotsuga menziesii Douglas Fir Needles occur on raised pegs; 3/4-11/4 inches in length; cones have 3-pointed bracts between the cone scales. Abies balsamea Abies concolor Balsam Fir White (Concolor) Fir Needles are blunt and notched at Needles are somewhat pointed, the tip; 3/4-11/2 inches in length. curved towards the branch top and 11/2-3 inches in length; silver green in color.

Franco from South-Eastern Poland Agnieszka Laskowska * , Karolina Majewska, Paweł Kozakiewicz , Mariusz Mami ´nskiand Grzegorz Bryk The Institute of Wood Sciences and Furniture, 159 Nowoursynowska St., 02-776 Warsaw, Poland; [email protected] (K.M.); [email protected] (P.K.); [email protected] (M.M.); [email protected] (G.B.) * Correspondence: [email protected] Abstract: Oriental arborvitae is not fully characterized in terms of its microscopic structure or physical or mechanical properties. Moreover, there is a lot of contradictory information in the literature about oriental arborvitae, especially in terms of microscopic structure. Therefore, the sapwood (S) and heartwood (H) of Platycladus orientalis (L.) Franco from Central Europe were subjected to examinations. The presence of helical thickenings was found in earlywood tracheids (E). Latewood tracheids (L) were characterized by a similar thickness of radial and tangential walls and a similar diameter in the tangential direction in the sapwood and heartwood zones. In the case of earlywood tracheids, such a similarity was found only in the thickness of the tangential walls. The volume swelling (VS) of sapwood and heartwood after reaching maximum moisture content (MMC) was 12.8% (±0.5%) and 11.2% (±0.5%), respectively. The average velocity of ultrasonic Citation: Laskowska, A.; Majewska, waves along the fibers (υ) for a frequency of 40 kHz was about 6% lower in the heartwood zone K.; Kozakiewicz, P.; Mami´nski,M.; than in the sapwood zone.

  • Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
    1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus).
