E-mail: [email protected] In the present investigation we studied the essential oil contents and compositions of three individual plants from Cupressaceae family cultivated in Vietnam. The air-dried plants were hydrodistilled and Tran D. Thang the oils analysed by GC and GC-MS. The components were identified by MS libraries and their RIs. Faculty of Biology, Vinh University, The wood essential oil of Calocedrus rupestris Aver, H.T. Nguyen et L.K.

Plant List 2016
Established 1990 PLANT LIST 2016 European mail order website www.crug-farm.co.uk CRÛG FARM PLANTS • 2016 Welcome to our 2016 list hope we can tempt you with plenty of our old favourites as well as some exciting new plants that we have searched out on our travels. There has been little chance of us standing still with what has been going on here in 2015. The year started well with the birth of our sixth grandchild. January into February had Sue and I in Colombia for our first winter/early spring expedition. It was exhilarating, we were able to travel much further afield than we had previously, as the mountainous areas become safer to travel. We are looking forward to working ever closer with the Colombian institutes, such as the Medellin Botanic Gardens whom we met up with. Consequently we were absent from the RHS February Show at Vincent Square. We are finding it increasingly expensive participating in the London shows, while re-branding the RHS February Show as a potato event hardly encourages our type of customer base to visit. A long standing speaking engagement and a last minute change of date, meant that we missed going to Fota near Cork last spring, no such problem this coming year. We were pleasantly surprised at the level of interest at the Trgrehan Garden Rare Plant Fair, in Cornwall. Hopefully this will become an annual event for us, as well as the Cornwall Garden Society show in April. Poor Sue went through the wars having to have a rush hysterectomy in June, after some timely results revealed future risks. -

Athyrium Niponicum 'Pictum'
A Horticulture Information article from the Wisconsin Master Gardener website, posted 30 Jan 2004 Athyrium niponicum ‘Pictum’ The Perennial Plant Association has named Athyrium niponicum ‘Pictum’ the 2004 Perennial Plant of the Year. This perennial low-maintenance Japanese painted fern is one of the showiest ferns for shade gardens. It is popular due to its hardiness nearly everywhere in the United States, except in the desert and northernmost areas in zone 3. ‘Pictum’ grows 18 inches tall and as it multiplies can make a clump that is more than two feet wide. ‘Pictum’ produces 12- to 18-inch fronds that are a soft shade of metallic silver-gray with hints of red and blue. This lovely fern, which prefers partial to full shade, makes an outstanding combination plant for adding color, texture, and habit to landscape beds and containers. Landscape Uses The magnifi cent texture and color of the fronds electrify shady areas of the garden and make the fern a wonderful companion for a variety of shade plants. Japanese painted fern provides a nice contrast to other shade-loving perennials such as hosta, bleeding heart, columbine, Fronds of Athyrium niponicum ‘Pictum’ astilbe and coral bells. A popular combination is Japanese painted fern with Hosta ‘Patriot’ and ‘Ginko Craig’. For something different, try Hosta sieboldiana ‘Elegans’. Another friendly companion plant for the Japanese painted fern is Tiarella (foam fl ower). One of the most unique possibilities is to use this fern with sedges. Carex (sedges) are shade-loving, easy-to-grow grasslike plants. Try Carex morrowii ‘Variegata’ or Carex siderosticha ‘Silver Sceptre’. -
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). -

GENOME EVOLUTION in MONOCOTS a Dissertation
GENOME EVOLUTION IN MONOCOTS A Dissertation Presented to The Faculty of the Graduate School At the University of Missouri In Partial Fulfillment Of the Requirements for the Degree Doctor of Philosophy By Kate L. Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field. -
