CANADIAN WEEDS: SCOTCH BROOM - CYTISUS SCOPARIUS
Peterson, D.J. and Prasad, R. 1998. THE BIOLOGY OF CANADIAN
WEEDS, 109. Cytisus scoparius (L.) Link. Canadian Journal of
Plant Science 78: 497-504.
Abstract: Scotch broom (Cytisus scoparius) is an exotic peren-
nial, leguminous, deciduous shrub, which during the past century
has greatly expanded its range along the Pacific and Atlantic
coasts of North America, and in Australia, New Zealand. South
Africa, Chile, Iran and India. This shrub rapidly invades dis-
turbed areas, forming dense thickets, which can suppress and
inhibit native vegetation, including economically important
conifer seedlings. The development characteristics whereby
Scotch broom invades new sites include specialized stem
photosynthesis, prolific seed production, longevity of seeds in
the soil, and nitrogen fixation. Human activities such as plant-
ing along highways for beautification and prevention of soil
erosion have accelerated the problem of rapid geographical
dispersal. Various methods of control (chemical, manual, and
biological) together with habitat morphology, reproductive
biology, growth and development are discussed.
PHRAGMITES CONFERENCE - TREBON, CZECH REPUBLIC, APRIL 1999
The International conference on Phragmites-dominated wetlands,
their functions and sustainable use. Trebon, Czech Republic,
April 18-23, 1999. Convener: Institute of Botany of the Academy
of Sciences of the Czech Republic.
All aspects of the biology and ecology of Phragmites and
Phragmites-dominated wetlands will be considered. The following
topics will be given priority:
1. Biogeochemical cycling in Phragmites-dominated ecosystems
2. Growth dynamics of Phragmites
3. Ecophysiology of Phragmites
4. Direct and indirect effects of eutrophication on Phragmites-
dominated ecosystems
5. Effects of environmental factors (e.g., salinity and water)
6. Effects of stochastic effects (e.g., fire and harvesting)
7. Genetic variability within and between Phragmites popula-
tions
8. Management and rehabilitation

REQUEST FOR PHOTOGRAPHS OF THE PACIFIC NORTHWEST PLANTS
From: Marie Fontaine <ocotillo@hotmail.com>
We need a few plant slides at the British Columbia Conservation
Data Centre; these plants are rare in our province, but may be
common in your area:
Sporobolus compositus
Castilleja pallescens
Orobanche corymbosa subsp. mutabilis
Pyrrocoma carthamoides
These slides would be used to illustrate a brochure on grassland
species at risk in British Columbia, put out by the B.C. Minis-
try of Environment, Lands & Parks. If you have any good slides
of these species in your collection, please contact me at:
ocotillo@hotmail.com
Thank you for your help.

The Michigan State University, East Leasing, seeks a full-time 2
year Collections Assistant for Lichens. The salary ($23,566
minimum, depending on experience) will be funded by a National
Science Foundantion grant for physical and curatorial improve-
ments to lichen collection. The MSU Herbarium houses one of the
largest lichen collection in the world and has strong repre-
sentation from Southern Hemisphere. During the two-year grant
period the Collections Assistant will be responsible for
processing our backlog of lichen species, overseeing a shift of
the lichen specimens in the herbarium, assisting visiting scien-
tists, coordinating our lichen exchange and loan programs, and
assisting with curation of the lichen collection. The position
