CBA/ABC ought to be able to represent itself at all levels. Indeed, Article 2 of the Constitution states, "The object of the Association shall be to encourage research and education in botany and to represent its members both nationally and internationally" (Italics mine). I cannot help but feel that, OFFICERS OF THE CBA/ABC SECTIONS 1975-76 no matter how well-intentioned the Biological Ecology Council of Canada and the Royal Society of Chairman: Canada are, their positions on matters of Dr. H. van Groenewoud national or international importance are not Maritime Forest Research Centre likely to coincide entirely with the position P.O.

BCC regional panels. At the end of the second day of meetings, Chairman: Dr. W.A. Fuller, I got the impression that the Biological De p artment of Zoology, Council of Canada was on the track so to speak University of Alberta, as far as the representation of several groups Edmonton, Alberta T6G 2E9. of Canadian biologists is concerned. The evidence for this is twofold. First we had Members: Dr. V.J. Krajina, distributed to us a penultimate draft of Department of Botany, "Tomorrows Biology - A National Statement on University of British Columbia, Basic Biology in Canadian Universities", Vancouver, B.C. V6T 1W5. familiarly known as the Mettrick-Walden report. The most significant aspect of the Dr. G.H. LaRoi, report is the fact that under the auspices of Department of Botany, the Science Council of Canada, three Canadian University of Alberta organizations representing different Edmonton, Alberta T6G 2E9. professional societies in the biological sciences coo p erated to synthesize the report. Dr. J.S. Rowe, The three organizations are: The Biological Department of Plant Ecology, Council of Canada, Canadian Committee of University of Saskatchewan, University Biology Chairmen, and the Canadian Saskatoon, Saskatchewan STN OWO. Federation of Biological Societies. Getting these three organizations to agree on the Dr. J.M. Shay, contents and presentation in the "statement" Department of Botany, is, I think we will agree, an important University of Manitoba, forward step for Canadian biologists. Winnipeg, Manitoba R3T 2N2. The "statement" in the penultimate stage is, in my opinion, well written and achieves a Dr. J.B. Falls, level that is easily understood by the layman. Department of Zoology, The presentation is based o n the thesis that Uniyersity of Toronto, governmental - "support for research in basic Toronto, Ontario M5S 1A1. biology has seriously deteriorated".

Compiled by Linda Kershaw and J.K. Morton, Department of Biology, University of Waterloo, Waterloo, Ontario N2L 3G1, Canada.

In assembling information for a list of endangered species in Canada it has become increasingly apparent that there are several levels of concern, each of which will generate its own q uite different list. 1) Canadian endemics of restricted range and species which are very rare throughout their range - ie. a list of what is "unique" to Canada. Such a list recognizes no national or provincial boundaries and should be of international significance. 2) A national list of plants which are very rare and/or very restricted in Canada. This list includes many species which, though common and often widespread in the U.S., are very rare and restricted in Canada. Its significance is primarily to Canadian botanists. 3) Provincial lists. These contain many species which, though common across neighbouring state or provincial borders, are rare or restricted in that province. 4) Local lists. Many of the species on these lists, though rare and rightly of concern to local botanists and naturalists, are nevertheless common in other parts of Canada and the adjoining United States. Each of these types of list has its own purpose and value. In our work we have concentrated on the first two types. The list that follows is of Canadian endemics of restricted range and includes species which occur in other countries (usually the U.S.) but are very rare throughout their range. Also included are major disjunct populations when these are of small size; a disjunction of 500 miles or more being the criterion for inclusion. The reason for including disjuncts is the fact that many are genetically distinct and of considerable phytogeographic as well as taxonomic significance. Aliens and adventives have been excluded from the list, as also have members of the two critical genera Crataegus and Rubus. Major problems in assembling the lists centre around synonomy and taxonomy. These problems are far from being resolved, and are probably greater in the Canadian flora because most of our endemics appear to be of recent origin and are closely related to other more widespread species. The list is of species, but some major infraspecific variations have been included and we have no doubt that others should be added to the list. Unfortunately there is frequent disagreement amongst botanists as to the status of this variation -- species, subspecies or variety. We are of the opinion that the list should not be encumbered by the inclusion of minor variation. Our list is based on the literature, an examination of several of the larger herbaria, on the provincial lists produced by Dr. Argus and others, and on personal communications from many of you. It is only intended as a preliminary list and we are sure it will prove to be incomplete and to contain taxa which do not warrant inclusion. However, we are at the stage where further searching of the literature and of herbaria is progressively less productive and the list needs the input of botanists and naturalists across Canada. For this reason we are publishing it in the Bulletin so as to reach as many of you as quickly as possible. We hope it will stimulate comment and criticism and that you will help us to produce a revised and more com p lete list. We consider that it is important for Canadians to know what is unique in their flora, and is thus deserving of the highest concern for its protection and continued survival. We also have compiled a national list which is available, as a computer print out, on request. Its size (some 1400 species are listed) makes p ublication prohibitive, at least in preliminary form. A high proportion of the species on this national list, though rare and restricted in Canada are common across the border in the U.S. and we are inclined to question the value of such a list. We feel that the concerns over these species are probably best handled at the local level.
