During the final hlO hundred years guy has replaced from dwelling in equilibrium with the wildlife which sustained him, to a brand new place within which he's now its undisputed ruler - and intensely frequently out of equilibrium - capable in an issue of hours to minimize miles of woodland to devastated, strength wasteland. This damaging and wasteful skill has increas~d dramatically over fresh years. whilst but the desire for conservation, quite of crops as a source for the longer term, has additionally develop into obvious, besides the realisation that complicated applied sciences can produce extra from latest agricultural and wooded area areas. this can to some degree relieve the heavy strain at the susceptible parts the place brief time period over-exploitation ends up in everlasting destruction of complete ecosystems, and the attendant loss, for ever, of a number of the animals and vegetation which initially lived there. There nonetheless is still at the present time an enormous variety of plant species whose capability is unknown. perhaps they're going to by no means have greater than aesthetic price to mankind. yet who understands the place, for instance, the following anti­ melanoma agent might be stumbled on. And besides destiny generations will not be able to settle for such anthropocentric values, and the choices could be stored open for the philosophical idea that all lifestyles in the world has a correct to exist and that guy has none to exterminate.

To help solve these problems the existing international network of botanic gardens can play and is now, in part, playing an increasingly valuable role by developing public awareness in plant conservation, creating and managing ecosystem reserves,. establishing propagating and distributing endangered plants, and forming seed banks. Equally important is the creation of facilities for fully documented autecological studies on threatened plants. For such is the scale of the problem that we neither know what we are losing nor even its potential value.

R. Suringar, the sixteenth director of the Hortus, had had a medical training but became the country's first professor of biology. At present, this separation is sometimes a matter of mild regret; medical students no longer come to the garden to learn about plants (",i th the exception of an occasional student with homoeopathic inclinations), although the pharmacology students still come to study plant collections at the beginning of their training. 1'iID PLANT HUNTING, TH~ GROHERS (NURSERYI1AN) The introduction of' private plant collecting was closely related to the expanding trade of the seventeenth and eighteenth centuries.

FUTURE: INTEGRATED INTERNATIONAL POLICIES R. L. Shaw Royal Botanic Garden Edinburgh, Scotland INTRODUCTION The more I think about this subject the more incompetent I feel. For a number of reasons a Curator's post these days leaves less and less time for horticulture in association with botany and becomes embroiled in general management matters, many of them wrongly placed and others quite trivial that, in earlier days, required or received little or no attention. Now with a more liberal, even a permissive industrial atmosphere what was quite constant and firm has become as insecure as shifting sand.
