The site was originally designed by Aki Peltonen (Stonehaven Innovations) and was modified and transferred to Lakehead University Faculty of Natural Resources Management in the spring of 2002. The site will continue to evolve with new additions such as international forestry and materials aimed at a young audiences.
To adequately protect plants and their habitats, conservation efforts and public awareness of these efforts must improve. Canadian Botanical Gardens host over 4.5 million visitors per year and are important science and educational facilities, providing leadership in plant conservation and public education.
The Botanical Society of America is a membership society whose mission is to: promote botany, the field of basic science dealing with the study and inquiry into the form, function, development, diversity, reproduction, evolution, and uses of plants and their interactions within the biosphere.
The society traces its origins back to 1836, when it was founded as the Botanical Society of London. From its earliest days it has welcomed both professional and amateur members, and it remains the biggest and most active organisation devoted to the study of botany in the British Isles.
The group is a collaboration between, but not exclusive to, former local groups representing The Botanical Society of the British Isles and The British Pteridological Society (ferns). Some members also belong to other societies such as The Wild Flower Society and the British Bryological Society (mosses and liverworts) and belong to charities such as Plantlife.
The Society is a registered not for profit organization that has 30 000 members spread across the world.
The Head Office of the Society is situated at Kirstenbosch where a small group of core personnel service and support the branches and manage projects along with the normal administration functions required by a large organization. By being a member of the Society one is part of a large group of individuals from around the world that support the mission and objectives of the Society.
The first Annual of the Society was published in 1938 under the heading of THE FUCHSIA ANNUAL 1938. The official publication of THE FUCHSIA SOCIETY.
However, it was during 1937 that the idea of a Fuchsia Society was born, when Clara Lady Boothby met several other Fuchsia enthusiasts, I therefore quote her opening Presidents Address to the Society published in the first Annual.

CactiGuide.com went live on May 5, 2002. Once I had the basic architecture of CactiGuide.com built, the next step was to gather content. I started taking pictures of plants that grew wild around Southern California and those that I had growing in my back yard. I then visited local cactus nurseries and local botanical gardens that I knew had cactus collections. I've also visited the Desert Botanical Garden and the Boyce Thompson Arboretum in Arizona and the Southern Arizona cactus-filled parks: Saguaro and Organ Pipe Cactus. I have been fortunate to explore cacti in Baja California and hope that some day I might visit mainland Mexico, then Central America, and ultimately the countries of South America. Admittedly, these are lofty goals for a man of my means and they won't be realized for years. Hence, CactiGuide.com will continue to be a work-in-progress long into the future. Last, but not least, there have been many other cacti enthusiasts who have joined with me to help provide images and other information to help "complete" the guide sooner.

OUR MISSION STATEMENT? We want to interest the expert rosarian and help the novice.
The Canadian Artists Rose Program was born out of a vision for the defunct Agriculture Canada rose breeding program. The bank of more than 15,000 rose cells in Agriculture Canada's plant vault was too important a collection to be set aside. The Program has since been driven by a series of successes in providing Canadian gardeners with the best choice of tough roses for our diverse climatic conditions, beginning with the introductions of 'Emily Carr' and 'Felix Leclerc'.
Biologically, the world is an astoundingly diverse place. It contains tens of millions of species, only a fraction of which have been identified. Canada's diversity of lifeforms and ecosystems is also large. Its landforms range from rainforest to desert, with mountains and plains, and each has species adapted to the conditions present there. Despite this diversity of life and land, most people have little idea of how diverse the country really is.
The Canadian Botanical Conservation Network's (CBCN) objective is to preserve the biological diversity of Canada's rare and endangered native plant species, wild habitats and ecosystems through the education and conservation programs of its members, including botanical gardens and arboreta.
In order to protect Canada's resource base the following pests are regulated. Pests in this list are linked to the policy directives that are available electronically from 1994 on, but some may also be referred to in directives dated prior to 1994. The list may be revised at any time.

Co's Digital Flora of the Philippines is actually a checklist of vascular plants native to the Philippine archipelago. Leonard Co worked his entire life updating the checklist produced by Merrill in the 1920s. As such, it is not an actual flora where one typically finds keys and descriptions of each species. Many species entries are also accompanied by other information such as distributions within and outside of the Philippines, flowering and fruiting times, and economic uses. We have called this a Digital Flora because the checklist is supplemented with thousands of photographs of the plants
Very little information about Coleus cultivars is published in books and articles, but a lot of information can be found on the internet. This information is very scattered and sometimes difficult to find though.
This portal has the goal to aggregate this scattered information together, to get a clear overview of the existing cultivars and their availability and also to get some clues about the correct naming of the cultivars.

China's plant life is enormously rich. Some 31,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. By comparison, the United States and Canada combined contain about 20,000 native plant species.
China is the only country on Earth where there are unbroken connections among tropical, subtropical, temperate, and boreal forests.
This unbroken connection has led to the formation of rich plant associations rarely seen elsewhere in the world. Many genera of plants which are known only from fossil records in North America and Europe are represented in China by living members. China also has the most diverse flora of any country in the North Temperate zone.
Mainland China and the continental United States share a common latitude and similar-sized land areas. The climates in much of the two regions are also similar, especially in the eastern halves. Many plant species that were once widespread throughout the entire northern hemisphere were wiped out by glaciation in North America but survived in China. Nearly 120 genera in 60 families of plants have disjunct populations in eastern Asia and temperate North America, relicts of the once widespread flora.

Unambiguous names for organisms are essential for effective scientific communication; names can only be unambiguous if there are internationally accepted rules governing their formation and use. The rules that govern scientific naming in botany (including phycology and mycology) are revised at Nomenclature Section meetings at successive International Botanical Congresses. The present edition of the International code of botanical nomenclature embodies the decisions of the XVII International Botanical Congress held in Vienna in 2005 and supersedes the Saint Louis Code, published six years ago subsequent to the XVI International Botanical Congress in St Louis, Missouri, U.S.A. It is written entirely in (British) English. The St Louis Code was translated into Chinese, French, Japanese, Portuguese, Russian, Slovak, and Spanish; it is therefore anticipated that the Vienna Code, too, will become available in several languages in due course.
