Littleleaf Boxwood Scientific Name: Buxus Microphylla Order Common Name: Littleleaf Boxwood Scientific Name: Buxus microphylla Order: Euphorbiales Family: Buxaceae Description Littleleaf boxwood has a flat, thin, green leaf. The leaf is about 2 ½ inches long in most cases. The leaf has no hair and being the plant is an evergreen it stays green year around. Littleleaf boxwood produces a very small clumped to gather flowers. The flowers are similar to that of most grasses and are generally unnoticeable. It contains both female and male parts so it can reproduce without pollination from another plant located nearby. From the flower a very small fruit is produced. The fruit when matured has a green color and smaller than a dime. The fruit from the littleleaf boxwood is shaped much like an acorn and is very dry. The fruit is undesirable to birds, squirrels, and other small animals. Growth Habit Littleleaf boxwood is a woody shrub it can range from 3-10 Feet tall. It is not found in the wild and is grown as a shrub hedge so is often kept trimmed back. Littleleaf boxwood has a brown bark that does not flack. The plant does not have thorns as most plants do especially in the immature stage so it is a good use around the home. The diameter of the trunk does not exceed the size of a coffee mug. Under its leafy exterior are many small tangled branches can be found growing mangled. Hardiness Zone(s) Littleleaf boxwood originated from the continent of Asia. According to the USDA Boxwood Report, littleleaf boxwood grows best in USDA zones 7, 8. Littleleaf boxwood can be grown in USDA zones 5, 6, 7, 8, 9. Only certain hardy plants originating from Korea can survive in the colder climates of USDA zone 5 and 6. Anywhere with a climate colder than that of USDA zone 5 is too cold for the plant to survive. Culture Boxwoods are tolerant of shade and sunlight. It is best to plant them somewhere close to a house or structure where they receive direct sunlight for part of the day and shade for the other part of the day. Boxwoods are a hardy plant that can thrive in many different soil types they can grow in soil types from heavy clay to sandy loom. Best results can be found when planted in a heavy clay with high organic mature. Boxwoods need the equivalent of one inch of rain every ten days. During the summer months watering may only be required every few weeks. Boxwood needs to be in a well-drained soil. If the desired area is not well drained a smaller hole should be dug allowing dirt to be mounding up around the remaining exposed roots. The best time to fertilize Boxwoods is in late fall or early spring. The recommended fertilizer is 10-6-4 applied at a rate of two pounds per hundred square feet of surface soil. The Boxwood is a very dense plant and should have the outer layer trimmed so that the inner shoots can receive light and air. At least once a year the debris should be removed from the plant; this can be done most times by simply shaking the bush. If the debris is not cleaned out it can promote fungus growth in the bush. Diseases & Insects There are three different types of diseases that affect the littleleaf boxwood, one that affects the leaf, stem, and the root. All diseases that affect the plant are fungus related funguses. Multiple insects infect the leaves of the littleleaf boxwood. The main pest of this plant is the boxwood mite. The boxwood mite is the larva of a small fly that hollows out the leaf as it eats it. Pesticides can be used to prevent and kill the insects that threaten the littleleaf boxwood. Landscape Value Littleleaf boxwood is primarily used as a hedge. It has been grown for thousands of yours dating back to the ancient Egyptians. With proper care and pruning the littleleaf boxwood can make and excellent hedge for your home or other landscape area. References Downs, A. and E. Blain. 2004. Littleleaf Boxwood.

  • 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.

K. Schneid. A variety of systematic affil­ iations has been suggested for the genus Simmondsia. It has been placed in the order Euphorbiales as a member of the Euphorbiaceae (Bentham and Hooker 1883), as a member of a monotypic family, the Simmondsiaceae (Takhtajan 1969), or as a member of the Buxaceae (Cronquist 1968), al­ though other workers are dubious of a close alliance between Simmondsia and the Buxaceae (Wiger 1935; Wunderlich 1967). Additional workers have suggested membership in the orders Hamamelidales (Hutchinson 1959), Cel­ astrales (Baillon 1877), or the Chenopodiales (van Tieghem 1897). Still oth­ ers have suggested a close relationship with the Garryaceae (Nuttall 1844) or Simaroubaceae (R. F. Thorne, pers. comm.). Thorne (1976) has listed Simmondsia as a taxon incerta sedis. Earlier phytochemical work by Scogin and Brown (1979) showed the leaf flavonoids of Simmondsia to be of little utility as a systematic discriminant because of their uniqueness. The present study was undertaken to determine whether comparative serology would favor a particular systematic relation­ ship for Simmondsia among the plethora of suggested possibilities.

  • 2 ANGIOSPERM PHYLOGENY GROUP (APG) SYSTEM History Of
    ANGIOSPERM PHYLOGENY GROUP (APG) SYSTEM The Angiosperm Phylogeny Group, or APG, refers to an informal international group of systematic botanists who came together to try to establish a consensus view of the taxonomy of flowering plants (angiosperms) that would reflect new knowledge about their relationships based upon phylogenetic studies. As of 2010, three incremental versions of a classification system have resulted from this collaboration (published in 1998, 2003 and 2009). An important motivation for the group was what they viewed as deficiencies in prior angiosperm classifications, which were not based on monophyletic groups (i.e. groups consisting of all the descendants of a common ancestor). APG publications are increasingly influential, with a number of major herbaria changing the arrangement of their collections to match the latest APG system. Angiosperm classification and the APG Until detailed genetic evidence became available, the classification of flowering plants (also known as angiosperms, Angiospermae, Anthophyta or Magnoliophyta) was based on their morphology (particularly that of the flower) and their biochemistry (what kinds of chemical compound they contained or produced). Classification systems were typically produced by an individual botanist or by a small group. The result was a large number of such systems (see List of systems of plant taxonomy). Different systems and their updates tended to be favoured in different countries; e.g. the Engler system in continental Europe; the Bentham & Hooker system in Britain (particularly influential because it was used by Kew); the Takhtajan system in the former Soviet Union and countries within its sphere of influence; and the Cronquist system in the United States.

  • Phylogenetic Classifications
    C.A.Bessy C. A. Bessey (1845-1915) was an American botanist, who laid the foundations of modern phylogenetic classifications. He was a student of Asa Gray and later became Professor of botany at the University of Nebraska. He was the first American to make a major contribution to plant classification, and also the first botanist to develop intentional phylogenetic classification. He based his classification on Bentham and Hooker, modified in the light of his 28 dicta and published in Ann. Mo. Bot. Gard. under the title‘The phylogenetic taxonomy of flowering plants’ (1915). Bessey considered angiosperms to have evolved monophyletically from Cycadophyta belonging to implied bennettitalean ancestry. He was the pioneer to consider that the large-sized bisexual flowers of Magnoliaceae with spirally arranged floral parts represent the most primitive conditionin angiosperms, a theory followed by many subsequent authors. Bessey believed in the strobiloid theory of the origin of the flower, the latter having originated from a vegetative shoot with spiral phyllomes, of which some modified to form sterile perianth, fertile stamens and carpels. Two evolutionary lines from such a flower formed strobiloideae (Ranalian line) with connation of like parts and cotyloideae (Rosalian line) with connation of unlike parts. Ranales in dicots and Alismatales in monocots were considered to be the most primitive in each group, a fact recognized by most subsequent authors. Ranalian plants were considered to be primitive angiosperms having given rise to monocots, but unfortunately monocots were placed before dicots. Bessey also initiated the representation of evolutionary relationships through an evolutionary diagram, a phylogram with primitive groups at the base and the most advanced at the tips of branches.

  • Simmondsia Chinensis Simmondsiaceae (Link) Schneider
    Simmondsia chinensis (Link) Schneider Simmondsiaceae LOCAL NAMES English (coffeeberry,quinine plant,wild hazel,pig nut,jojoba,gray box bush,goat nut,deer nut,coffee bush) BOTANIC DESCRIPTION Simmondsia chinensis is a leafy, xerophytic, woody evergreen dioecious shrub or small multi-stemmed tree that grows to a height of 0.5–1 m in the wild, occasionally to 6 m tall with taproots to 12 m long. Leaves opposite, oval or lanceolate, grey green or bluish-green, leathery, Leaves (©J.S. Peterson. USDA NRCS oblong, opposite, 2.5–3.5 cm long and contain special tissue with a high NPDC. Quail Botanical Garden, San Diego concentration of phenol compounds. Co., CA.) Flowers apetalous, dioecious; the male flowers are yellow, larger, and occur in clusters with 10–12 stamens per flower; female flowers small, usually solitary in the axils or in clusters at the nodes, pale green with 5 greenish sepals, soft and hairy. Fruits green capsules, ovoid, usually dehiscent with 1-3 seeds. Seed peanut-sized, dark brown, the endosperm scanty or absent The first taxonomic description of this species appeared in 1822, when Johann Link named it as Buxus chinensis but later changed to Simmondsia californica in 1844 by Thomas Nuttall. In 1912, the Austrian botanist, Camillo Karl Schneider, renamed it as Simmondsia chinensis. Although earlier botanists placed jojoba in the family Buxaceae, many other botanists believe that it should be placed in its own family due to its morphological and anatomical distinctiveness. BIOLOGY Jojoba is a dioecious, wind-pollinated shrub. Flower buds form in the axiles of leaves. Anthesis occurs in March to June when the soil and air temperature rise to above 15°C.
