Excerpt from Collecting Data and Specimens for Study of Economic Plants Only rarely can a satisfactory answer be given to inquiries about some native plant when nothing more is known than its local or vernacular name. A native name for a plant in a foreign country may not have any more significance than would a common name in the United States. A plant called brown daisy in one State may well be known as blue eyed marigold in another. In Latin American countries, also, the common name Of a plant Often varies from one locality to another. For this reason, the local name is not a sufficient clue to the botanical iden tity Of a plant. Likewise, people Often send in a single leaf, a piece Of stem, or a root only to learn that small fragments are inadequate. Bota nists need a sufficient portion Of a plant, with flowers or fruits, some times both, -in order to identify it and to assign the correct botanical name. The specimen must be pressed flat and dried before shipping. Fresh plants wrapped in Oilpaper for mailing usually arrive completely decayed. A plant tucked into an envelope arrives in a shriveled condi tion or else shattered to bits. The best method Of assuring safe shipment is to protect the dried specimen with two pieces Of stout cardboard. Insect and diseased-plant specimens, as well as analysis and propaga tion material, also must be adequate in quantity, properly prepared, and carefully packed. Fungi and insects should never be shipped from one country to another while still. Alive, unless specifically requested by specialists; and in that event special arrangements would need to be made to conform with the quarantine laws Of the countries concerned.

As climate change continues to dominate the international environmental agenda, phenology – the study of the timing of recurring biological events – has received increasing research attention, leading to an emerging consensus that phenology can be viewed as an ‘early warning system’ for climate change impact. A multidisciplinary science involving many branches of ecology, geography and remote sensing, phenology to date has lacked a coherent methodological text. This new synthesis, including contributions from many of the world’s leading phenologists, therefore fills a critical gap in the current biological literature. Providing critiques of current methods, as well as detailing novel and emerging methodologies, the book, with its extensive suite of references, provides readers with an understanding of both the theoretical basis and the potential applications required to adopt and adapt new analytical and design methods. An invaluable source book for researchers and students in ecology and climate change science, the book also provides a useful reference for practitioners in a range of sectors, including human health, fisheries, forestry, agriculture and natural resource management.

Excerpt: ... Vol. VIII, No. 13, July 19, 1918 BOTANICAL SOCIETY OF WASHINGTON The 129th regular meeting of the Society was held at the Cosmos Club at 8 p.m., Tuesday, May 7, 1918; 31 members and 3 guests present. Prof. A. S. Hitchcock presided. The following scientific program was given. William A. Dayton: Collecting data on National Forest range plants. For nine years past the Forest Service has conducted a study of the distribuation, natural habits, and'economic importance of its range flora. Approximately 35,000 plant specimens, representing about 4,800 species, have been collected on National Forests and Purchase Areas. Ecological and economic data have been furnished by the collectors of most of these specimens, and this material has been supplemented by much detailed data procured by grazing experts of the Service. The specimens have been identified by experts of the Bureau of Plant Industry. Economic notes are compiled in the Washington office and distributed among Forest officers. These data have application to many phases of range-management, e.g., intensive range-utilization especially with a view to minimum interference with the requirements of the important forage plants, and the utilization of each type at the time and by the class of stock to which it is best adapted; detection, eradication, fencing, etc. of poisonous-plant areas; natural range reseeding; studies in carrying capacity, plant indicators, plant succession, artificial reseeding, etc. W. W. Eggleston: Nathaniel Jarvis Wyeth and his influence on western botany, with a sketch of his return trip from Oregon in 1838. Capt. N. J. Wyeth was born in Cambridge, Massachusetts, in 1802. His father was a Harvard graduate. Captain Wyeth received a business training, was one of the pioneers in the ice busi..
