January 15, 1994 - Fern Growth and Identification by Judith Jones, manager of Fancy Fronds, a national wholesale grower of ferns. January 29, 1994 - Ecology of the Lowland Forest by Dave Peter, Forest Ecologist with the Olympic National Forest. February 19, 1994 - Moss Identification by Kelly McGrew, amateur bryologist. February 26, 1994 - Flora of the Puget Sound and It's Origins by John Gamon, Botanist at the Natural Heritage Program of the Department of Natural Resources. All workshops will be held at South Puget Sound Community Col- lege. Sessions begin at 8:30 AM and will last until ap- proximately noon. If there is interest, some instructors will offer a second workshop in the afternoon from 1:00 PM until approximately 4:30 PM. There is no charge for these workshops but priority seating will be given to WNPS members. Because seating is limited you must sign up in advance. To sign up please call Kelly McGrew at 206-953-8533 or e-mail to 1994 JOINT FIELD MEETING of The Botanical Society of America, The Torrey Botanical Club, and The Philadelphia Botanical Club. The 1994 Joint Field Meeting will take place Sunday afternoon to Thursday morning, June 26-30, at Frostburg State University in western Maryland. The field trips will examine plants of shale barrens, swamps, old-growth forests, bogs and Triassic uplands. Evening programs will deal with aspects of the the flora visited, with the geology of the region, and with the management of the threatened species. The price is $175.00 per person. This includes housing, meals, bus transportation, trip leadership and evening programs.

The weevil has been associated with declining populations of watermilfoil in the northeastern United States. Robert Creed and Sallie Sheldon (Dept. of Biology, Middlebury College, Vermont) found that all life stages of the weevil are associated with Eurasian watermilfoil. Adults lay their eggs on the meristems; larvae burrow into and feed on the meristems before moving down and into the stem. Pupation occurs inside the stem. Adults feed on the stems, leaves and leaflets of watermil- foil, and mate on the plant. They appear to concentrate feeding on the upper portions of the plant, removing significant amounts of photosynthetic tissue. Also, stem damage from both adults and larvae causes watermilfoil to lose its buoyancy and sink. The researchers suggest that the loss of buoyancy may be more sig- nificant in controlling the plant than the loss of leaves. The weevils appear to prefer the exotic Myriophyllum spicatum over the native milfoil (M. sibiricum = exalbescens). Creed and Sheldon suggest that the weevil may have either expanded its diet to include M. spicatum or undergone a host shift from the native plant to the exotic one. Ref.: Creed, R.P., Jr. & S.P. Sheldon. 1993. The effect of feeding by a North American weevil, Eurhychiopsis lecontei on Eurasian watermilfoil (Myriophyllum spicatum). Aquatic Botany 45: 245-256.

K.R. Adams of the Crow Canyon Archeological Center in Cortez, Colorado, sampled a dozen of cigarettes and confirmed previous suggestions: the 600-year-old smokes are made from the stem of the giant reed (Phragmites australis), and contain tobacco (Nicotiana spp.). The reed "barrel" of the cigarette was stuffed with tobacco. The tobacco was lit and smoked; the tough reed exterior did not burn, and was used again. In her review of other research, the author found that other "historic North America groups" (Hopi, Comanche, etc.) smoked parts of at least 13 kinds of plants and at least one kind of bird feathers.

AQUAPHYTE Aquaphyte is a newsletter published by the Center for Aquatic Plants and the Aquatic Plant Information Retrieval System (APIRS) of the University of Florida (7922 N.W. 71st Street, Gainesville, FL 32606, USA). It is sent to 5,000 managers, researchers and agencies in 87 countries [and it seems to be free-of-charge !]. Besides articles on aquatic plants and vegetation, Aquaphyte publishes excerpts from APIRS bibliog- raphic data base, book reviews, and announcements of meetings. THE ALASKA VEGETATION CLASSIFICATION Viereck, L.A., C.T. Dyrness, A.R. Batten & K.J. Wenzlick. 1992. The Alaska vegetation classification. Gen. Tech. Rep. PNW-GRT- 286, Portland, OR. 278 p. Abstract: The Alaska vegetation classification presented here is a comprehensive, statewide system that has been under develop- ment since 1976. The classification is based, as much as pos- sible, on the characteristic s of the vegetation itself and is designed to categorize existing vegetation, not potential vegetation. A hierarchical system with five levels of resolution is used for classifying Alaska vegetation. The system, an ag- glomerative one, starts with 888 known Alaska plant communities, which are listed and referenced ... [Glossary of terms, list of species mentioned, and 480 references. Great book!
