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.

We report here for the first time the occurrence of a member of the genus in China, Stillingia lineata subsp. pacifica. The distribution of the genus in China is apparently narrow, known only from Pingzhou and Wanzhou Islands of the Wanshan Archipelago in the South China Sea, which is close to the Pearl River estuary. This study updates our knowledge on the geographic distribution of the genus, and provides new palynological data as well. Key words: Island, Hippomaneae, South China Sea, Stillingia lineata Introduction During the last decade, hundreds of new plant species or new species records have been added to the flora of China. Nevertheless, newly described or newly recorded plant genera are not discovered and reported very often, suggesting that botanical expedition and plant survey at the generic level may be advanced in China. As far as we know, only six and eight angiosperm genera respectively have been newly described or newly recorded from China within the last ten years (Qiang et al.

Shirakia bleek eerder gegeven te zijn aan een fossiel varengeslacht uit Zuid-Korea en is dus volgens de Interna- tional Code of Botanical Nomenclature een homoniem. Toen dit in 1996 aan het licht kwam, moest er een nieuwe geslachtsnaam komen en dat werd Neoshirakia. Deze werd in 1998 door Esser gepubliceerd in het in Leiden door Naturalis uitgegeven weten- schappelijke tijdschrift Blumea.

  • Neoshirakia, (Euphorbiaceae) 1 Japonica (Siebold & Zucc.) Esser
    BLUMEA 43 (1998) 129-130 Neoshirakia, a new name for Shirakia Hurus. (Euphorbiaceae) Hans-Joachim Esser Rijksherbarium/Hortus Botanicus, P. O. Box 9514, 2300 RA Leiden, The Netherlands 1 Shirakia (Euphorbiaceae) was described by Hurusawa (1954) with three species. It was namedafter Croton shiraki, a nomen nudum used by Siebold& Zuccarini (1843) for the species currently known as S. japonica (Siebold & Zucc.) Hurus. Kruijt (1996) transferred five additional species to Shirakia. Esser et al. (1998) showed that S. ja- ponica, the type, differs in several characters from the remainder of the genus. In a phylogenetic analysis they concluded that all additional species have to be removed to other genera (Shirakiopsis Esser ined., TriadicaLour.), with Shirakia remaining as endemic and Asia. a monotypic genus to Japan adjacent East The name, however, is a later homonym of Shirakia S. Kawasaki, a fern fossil described in 1934 from South Korea. This informationis included in the WWW ver- sion of the Index Nominum Genericorum (Farr & Zijlstra, 1996 and onward). Be- cause this earlier homonym was published in a publication of very restricted distribu- tion, it was overlooked by recent workers (Kruijt, 1996;Esser et al., 1998). GeaZijlstra and John Wiersema kindly confirmed that a new name is still necessary for Shirakia Hurus., and this is provided herewith. NEOSHIRAKIA Esser, nom. now Excoecaria L. sect. Parasapium Mull.

Wallace Endowed Plant Propagation Intern Date: January 2020 Abstract: In this gap analysis of the Morris Arboretum’s Hydrangea collection, I will assess the hydrangea collection with a focus on the “fuzzy leaf” varieties that fall under two classifications: Section Asperae and Section Chinenses. Within these fuzzy leaf groupings, this project will include an analysis of the collection at the species and cultivar level and will outline which hydrangeas are missing from or underrepresented in our collection, as well as recommendations for suitable additions. These recommendations favor wild collected species and species available from the collections at regional arboreta. Discussion of the controversy over nomenclature verification methods, phylogenic treatments, and theories of biological classification systems are explored in the body of this paper. This project also entails seed propagation of target species growing at the Arboretum, and cutting propagation of desired species from local institutions to diversify this growing collection.

W. Mennega Nationaal Herbarium Nederland, Utrecht University branch, Heidelberglaan 2, 3584 es Utrecht, The Netherlands SUMMARY The wood anatomy was studied of 82 species from 34 out of 54 genera in the subfamily Euphorbioideae, covering all five tribes recognized in this subfamily. In general the woods show a great deal of similarity. They are charac­ terized by a relative paucity of vessels, often arranged in short to long, dumbbell-shaped or twin, radial multiples, and by medium-sized to large intervessel pits; fibres often have gelatinous walls; parenchyma apotracheal in short, wavy, narrow bands and diffuse-in-aggregates; mostly uni- or only locally biseriate rays, strongly heterocellular (except Hippomane, Hura and Pachystroma). Cell contents, either silica or crystals, or both together, are nearly always present and often useful in distinguishing between genera. Radiallaticifers were noticed in most genera, though they are scarce and difficult to trace. The laticifers are generally not surrounded by special cells, except in some genera of the subtribe Euphorbiinae where radiallaticifers are comparatively frequent and conspicuous. Three ofthe five tribes show a great deal of conformity in their anatomy. Stomatocalyceae, however, stand apart from the rest by the combination of the scarcity of vessels, and mostly biseriate, vertically fused and very tall rays. Within Euphorbieae the subtribe Euphorbiinae shows a greater vari­ ation than average, notably in vessel pitting, the frequent presence of two­ celled parenchyma strands, and in size and frequency of the laticifers.

  • Vascular Flora of The
    VASCULAR FLORA OF THE UPPER ETOWAH RIVER WATERSHED, GEORGIA by LISA MARIE KRUSE (Under the Direction of DAVID E. GIANNASI) ABSTRACT The Etowah River Basin in North Georgia is a biologically diverse Southern Appalachian River system, threatened by regional population growth. This is a two-part botanical study in the Upper Etowah watershed. The primary component is a survey of vascular flora. Habitats include riparian zones, lowland forest, tributary drainages, bluffs, and uplands. A total of 662 taxa were inventoried, and seventeen reference communities were described and mapped. Small streams, remote public land, and forested private land are important for plant conservation in this watershed. In the second component, cumulative plant species richness was sampled across six floodplain sites to estimate optimal widths for riparian buffer zones. To include 90% of floodplain species in a buffer, 60-75% of the floodplain width must be protected, depending on the stream size. Soil moisture influences species richness, and is dependent on upland water sources. An optimal buffer would protect hydrologic connections between floodplains and uplands.

Issued April, 1930 PLANT MATERIAL INTRODUCED BY THE OFFICE OF FOREIGN PUNT INTRODUCTION, BUREAU OF PLANT INDUSTRY, OCTOBER 1 TO DECEMBER 31,1928 (NOS. 77596 TO 78508) CONTENTS Paare Introductory statement 1 Inventory 3 Index of common and scientific names 45 INTRODUCTORY STATEMENT This inventory for the period from October 1 to December 31, 1928, contains a large amount of material which was brought in for experimental purposes, and will affect the final cooperative experiments very little, if at all. This is largely true of the plants obtained by the various expeditions that have been in the field for specific purposes. From R. K. Beattie, who is still in the Orient, have been received consider- able collections of Japanese persimmon varieties (Diospyros kaki, Nos. 78487 to 78503), Castanopsis spp. (Nos. 78312 to 78316), and Japanese chestnuts (Gas- tanea crenata, Nos. 78003 to 78031), as well as miscellaneous ornamentals and trees. From the Brandes collecting trip in New Guinea has been brought back a large collection of sugarcanes {Saccharum spp., Nos. 77710 to 77816). From Madagascar, Charles F. Swingle has brought back not only Euphorbia intisy (No. 78169), a source of rubber, but a large miscellaneous collection of other species, some of them possibly also sources of rubber, and others merely of interest as ornamentals. Among the latter the most curious and interesting are the Kalanchoes (Nos. 77907 to 77917, 78423 to 78438, and possibly others), which will probably be useful out of doors in the warmest parts of the United States and as pot plants throughout the rest of the country.
