Seiridium Canker of Cypress Trees in Arizona Jeff Schalau
ARIZONA COOPERATIVE E TENSION AZ1557 January 2012 Seiridium Canker of Cypress Trees in Arizona Jeff Schalau Introduction Leyland cypress (x Cupressocyparis leylandii) is a fast- growing evergreen that has been widely planted as a landscape specimen and along boundaries to create windbreaks or privacy screening in Arizona. The presence of Seiridium canker was confirmed in Prescott, Arizona in July 2011 and it is suspected that the disease occurs in other areas of the state. Seiridium canker was first identified in California’s San Joaquin Valley in 1928. Today, it can be found in Europe, Asia, New Zealand, Australia, South America and Africa on plants in the cypress family (Cupressaceae). Leyland cypress, Monterey cypress, (Cupressus macrocarpa) and Italian cypress (C. sempervirens) are highly susceptible and can be severely impacted by this disease. Since Leyland and Italian cypress have been widely planted in Arizona, it is imperative that Seiridium canker management strategies be applied and suitable resistant tree species be recommended for planting in the future. The Pathogen Seiridium canker is known to be caused by three different fungal species: Seiridium cardinale, S. cupressi and S. unicorne. S. cardinale is the most damaging of the three species and is SCHALAU found in California. S. unicorne and S. cupressi are found in the southeastern United States where the primary host is JEFF Leyland cypress. All three species produce asexual fruiting Figure 1. Leyland cypress tree with dead branch (upper left) and main leader bodies (acervuli) in cankers. The acervuli produce spores caused by Seiridium canker. (conidia) which spread by water, human activity (pruning and transport of infected plant material), and potentially insects, birds and animals to neighboring trees where new Symptoms and Signs infections can occur. -

FEATURES Cupressus macrocarpa. Photographer: Peter de Medium sized tree to about 36 metres. Has distinctive fluted trunk when Lange mature, bark is thick, reddish brown beneath often becoming whitish on the surface. Adult foliage comprises many small dark green scales closely appressed to the branchlets, but not flattened. Juvenile foliage more needle like, and not appressed. Male cones up to about 3 mm long, yellow and knobbly arising on the tips of the branches. Female cone are also terminal, rosette-like at first, becoming a rounded brown cone with 8-14 scales when mature. Usually 10-20 small seeds per cone scale. SIMILAR TAXA The scales closely appressed on mature plants, but stems not becoming flattened separate Cupressus from other conifers. There are several Cupressus species in cultivation in New Zealand but C. macrocarpa is by far the most common, and can be identified by the blunt leaves lacking resin glands, and the shining brown mature cones.

America ETYMOLOGY cupressus: Classical name, said to be derived from the Greek kuo ‘to produce’ and pari ‘equal’, alluding to the symmetrical form of the Italian cypress; alternatively the name is derived from an ancient Latin word for box, the wood once being used for coffins. macrocarpa: Large fruit Reason For Introduction Forestry Life Cycle Comments Occasional and scattered cultivation escape in the vicinity of planted trees (Webb et al 1988). -
Non-Expressway Master Plant List
MASTER PLANT LIST GENERAL INTRODUCTION TO PLANT LISTS Plants are living organisms. They possess variety in form, foliage and flower color, visual texture and ultimate size. There is variation in plants of the same species. Plants change: with seasons, with time and with the environment. Yet here is an attempt to categorize and catalogue a group of plants well suited for highway and expressway planting in Santa Clara County. This is possible because in all the existing variety of plants, there still remains a visual, morphological and taxonomical distinction among them. The following lists and identification cards emphasize these distinctions. 1 of 6 MASTER PLANT LIST TREES Acacia decurrens: Green wattle Acacia longifolia: Sydney golden wattle Acacia melanoxylon: Blackwood acacia Acer macrophyllum: Bigleaf maple Aesculus californica: California buckeye Aesculus carnea: Red horsechestnut Ailanthus altissima: Tree-of-heaven Albizia julibrissin: Silk tree Alnus cordata: Italian alder Alnus rhombifolia: White alder Arbutus menziesii: Madrone Calocedrus decurrens: Incense cedar Casuarina equisetifolia: Horsetail tree Casuarina stricta: Coast beefwood Catalpa speciosa: Western catalpa Cedrus deodara: Deodar cedar Ceratonia siliqua: Carob Cinnamomum camphora: Camphor Cordyline australis: Australian dracena Crataegus phaenopyrum: Washington thorn Cryptomeria japonica: Japanese redwood Cupressus glabra: Arizona cypress Cupressus macrocarpa: Monterey cypress Eriobotrya japonica: Loquat Eucalyptus camaldulensis: Red gum Eucalyptus citriodora: Lemon-scented -
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). -
