    Insert as an Additional Taxa For Ardisia japonica: Ardisia crenata J. Sims Coralberry (Ardisia crenulata) C This is species is also known as Spiceberry; Coralberry is a larger version of A. japonica forming a rounded woody evergreen shrub 3N to 5N(6N) tall; the 4O to 6O(8O) long elliptic-lanceolate to oblanceolate lustrous dark green leaves have crenate-undulate margins; the foliage tends to be bunched toward the ends of the stems; the specific epithet refers to these crenate leaves. C Plants have small ¼O long white to pink inverted urn-shaped flowers in cymes in spring to summer; however, the species’ primary asset is the massed clusters of bright shiny red fruits; they are extremely showy, contrasting handsomely with the dark green foliage, ala a holly mimic. C Originating from Japan and Southeast Asia, this species has limited cold tolerance, but good heat tolerance’ it is effective in USDA zones 8(7) to 10 landscapes; plants are prolific seed producers and have naturalized extensively in eastern portions of the Gulf Coast; they are often found along woodland edges, but can tolerate full sun where adequate moisture is available; growth is best in well drained, moist, fertile, acidic to neutral soils; unfortunately, A. crenata can become weedy in favorable environments. C Ardisia crispa (C. Thunberg) A.P. de Candolle, Coral Ardisia, is a similar, but less cold hardy groundcover sometimes encountered along the Gulf Coast in South Texas or as an interiorscape plant.

  • The Problem of Identifying Mudan 牡丹and the Tree Peony in Early
    Asian Medicine 5 (2009) 108–145 brill.nl/asme The Problem of Identifying Mudan 牡丹 and the Tree Peony in Early China Teruyuki Kubo Abstract The tree peony is a flowering plant found in China, and well-known in Britain. Its root cortex is often used in Chinese traditional prescriptions, such as Dahuang mudan tang, Liuwei dihuang wan, and Jiawei shaoyao san. In contemporary Chinese, the tree peony is called ‘mudan’, and although its beauty was largely ignored until the Kaiyuan era (713–41 CE), a drug of the same name is mentioned in medical texts of the Eastern Han period (25–220 CE). The early authori- tative materia medica, Xinxiu bencao (659 CE), also describes a plant called ‘mudan’, but it is different from the tree peony in form. Curiously, although the tree peony is not considered to be native to Japan, it is described as a specialty plant in the early Japanese gazetteer, Izumonokuni Fudoki (733 CE). This study demonstrates that in early texts mudan’‘ referred to a different plant from the tree peony, and that ‘mudan’ had two remarkable aliases, ‘bailiangjin’ in China and ‘yamatachihana’ in Japan. Today, both aliases are used to refer to Ardisia species. Furthermore, I will demonstrate that the Xinxiu bencao’s description of the mudan closely matches that of the Ardisia, especially the A. japonica species. My investigations therefore suggest that early prescriptions may have used the Ardisia species, not the tree peony. This raises further questions: when and how did the tree peony come to replace the Ardisia? This paper presents the most likely progression of this transition by tracing the expansion of cultivation of mudan for ornamental purposes.

China ABSTRACT A new, effective and economical method to extract ardicrenin from Ardisia crenata Sims collected in the Wolong natural reserve, Sichuan, China, is established. Ardisia crenata Sims powder is counter-current extracted with 80% methanol reflux, decompressively enriched and centrifuged to defat. Supernatant is applied to macroporous resin column (AB-8) with 80% methanol, ardicrenin is isolated by silica gel chromatography with dichlormethane-aceto- acetate-methanol (4:1.5:1) washing, and recrystallized in methanol. The final product which proved to be ardicrenin by analytic procedure including Furier transform infrared (FTIR) and ultraviolet spectrum (UV), mass spectroscopy (MS), nuclear magnetic resonance (NMR) and high performance liquid chromatography (HPLC) is white amor- phous powder with yield of 1.59 ± 0.02%.

  • Ardisia Japonica – Established and Spreading in the Wild in Florida by Robert Simons
    Ardisia japonica – Established and Spreading in the Wild in Florida by Robert Simons The genus Ardisia is well known to Florida natural area land managers. One native species (A. escallonioides) is common in southern and central peninsular Florida, and two introduced species have been designated as FLEPPC Category I invasive plant species (A. elliptica and A. crenata). Another species, Ardisia japonica (often called Japanese ardisia in the horticultural trade) can be purchased from nurseries scattered about the United States, and has been cultivated locally (Alachua County, Florida) at San Felasco Nursery and at Kanapaha Botanical Garden. It has never previously been reported to escape from cultivation and establish populations in the wild. n November 1, 2008, Cara Gwalthney (Florida Park Ser- vice District 2) and I discovered three patches of Ardisia Ojaponica in San Felasco Hammock Preserve State Park and had samples identified by Kent Perkins at the University of Florida herbarium. The patches ranged from approximately 6 meters to 60 meters in diameter and were roughly circular in shape. They The appearance of Ardisia japonica is were not connected to or near each other or any other populations distinct from other species of Ardisia of the species, and thus appeared to have either originated from that are reported to occur in the wild in seed or to have been planted.

  • ABSTRACT the First Through Fifth Instars of the Gypsy Moth Were Tested for Development to Adults on 326 Species of Dicotyledonous Plants in Laboratory Feeding Trials
    LABORATORY FEEDING TESTS ON THE DEVELOPMENT OF GYPSY MOTH LARVAE WITH REFERENCE TO PLANT TAXA AND ALLELOCHEMICALS JEFFREY C. MILLER and PAUL E. HANSON DEPARTMENT OF ENTOMOLOGY, OREGON STATE UNIVERSITY, CORVALLIS, OREGON 97331 ABSTRACT The first through fifth instars of the gypsy moth were tested for development to adults on 326 species of dicotyledonous plants in laboratory feeding trials. Among accepted plants, differences in suitability were documented by measuring female pupal weights. The majority of accepted plants belong to the subclasses Dilleniidae, Hamamelidae, and Rosidae. Species of oak, maple, alder, madrone, eucalyptus, poplar, and sumac were highly suitable. Plants belonging to the Asteridae, Caryophyllidae, and Magnoliidae were mostly rejected. Foliage type, new or old, and instar influenced host plant suitability. Larvae of various instars were able to pupate after feeding on foliage of 147 plant species. Of these, 1.01 were accepted by first instars. Larvae from the first through fifth instar failed to molt on foliage of 151 species. Minor feeding occurred on 67 of these species. In general, larvae accepted new foliage on evergreen species more readily than old foliage. The results of these trials were combined with results from three previous studies to provide data on feeding responses of gypsy moth larvae on a total of 658 species, 286 genera, and 106 families of dicots. Allelochemic compositions of these plants were tabulated from available literature and compared with acceptance or rejection by gypsy moth. Plants accepted by gypsy moth generally contain tannins, but lack alkaloids, iridoid monoterpenes, sesquiterpenoids, diterpenoids, and glucosinolates. 2 PREFACE This research was funded through grants from USDA Forest Service cooperative agreement no.
