VanDusen Botanical Garden presents: "Botanic gardens & conservation" - A Special Lecture with Timothy Walker, Superintendent of the University of Oxford Botanic Garden.
As we approach the next millennium, botanical gardens world-wide are taking a leading role in plant conservation. Join Timothy Walker as he explores botanical gardens that have turned to their own backyards to conserve and study local flora, and are now working together to preserve plant diversity and protect threatened and endangered species.
Monday, June 23, 1997 at 8 pm in VanDusen Botanical Garden's Floral Hall. Tickets: $10 (Canadian) VanDusen Members; $15 (Canadian) Non-members.

All species in the family Hypericaceae that are known to grow in British Columbia can be found within a relatively small area around the Fraser River delta near Vancouver. Although there are only two or three native species in British Columbia, a growing number of introduced species have complicated what was once an easy family to key out. I hope the following key will be useful.
Key was adapted from The Flora of Canada Part 3, H.J. Scoggan 1978-79, Flora of the British Isles, Clapham, Tutin and Moore l989, and my own observations.

The new Alaska Region brochure entitled WILDFLOWERS OF THE NATIONAL FORESTS IN ALASKA has just been published. About 150,000 copies were printed and sent to Forest Service units throughout the Alaska Region for distribution to the public.
WILDFLOWERS OF THE NATIONAL FORESTS IN ALASKA contains color photographs and descriptive information highlighting 50 of the most common wildflowers occurring in southern Alaska.
The production of the brochure was coordinated by the Alaska Region Botany Program in response to numerous wildflower identification questions from the public. They were also developed enhance people's awareness of Alaska's flora.
