MENZIESIA - A NEW BOTANICAL PERIODICAL IN BRITISH COLUMBIA
From: Adolf Ceska [email@example.com]
Menziesia is a relatively new botanical journal, a newsletter of the NPSBC Native Plant Society of British Columbia. With its latest issue (Volume 4, Issue 4, Fall 1999), Menziesia reached its maturity. Its editor, Harry Hill, has come up with an interesting set of articles wrapped in a pleasant format. In the past, and in this issue as well, several articles have been reprinted from BEN. In the last issue of Menziesia, James B. Phipps provided a significant update to his hawthorn (Crataegus) key originally published in the issue of BEN dedicated to Dr. Chris Brayshaw ( BEN # 209). His new key and his notes to individual species is a nice summary of several taxonomical papers published in botanical journals by Dr. Phipps and his co-workers. From the original articles, "Development of a Code of Ethics" gives an insight in the work of the Native Plant Society, Malcolm Martin's article "So where are all the rarities" summarizes Malcolm's experience with botanical explorations in the northern Okanagan Valley, and David Williams' column "What's in a name" explains the origin of plant names. Elisabeth Beaubien gives you an overview of the Canada-wide "Plantwatch" phenological program with the instructions on how to join the network. It is great to see a broad variety of topics, many thanks, Harry.
The NPSBC Native Plant Society of British Columbia was established in 1997 "to encourage knowledge, appreciation, responsible use and conservation of British Columbia's native plants and habitats." At this time, NPSBC has about 300 members. The Society sponsors symposia, lectures, slide shows, field trips and various workshops. Last year (1999) there were four workshops (native plant propagation, grass and willow identification and ethnobotany), and many more workshops will be offered this year (2000).

EPHEMERAL INTRODUCTIONS OF VASCULAR PLANTS AROUND VANCOUVER, BRITISH COLUMBIA (PART 1)
From: Frank Lomer c/o [email@example.com]
I have collected the following species in the Vancouver area during the last twelve years. These species cannot be considered part of our flora because they have not persisted, or if they still exist, they have not spread from their original locations. The voucher specimens are deposited in the University of British Columbia herbarium (UBC).
- Acnida tamariscina (Nutt.) Wood - Amaranthaceae
Loc.: Railroad tracks west of North Rd. near Brunette River,
Burnaby; Nov. 3, 1992; # 92320.
Like Amaranthus, but plants are dioecious (see Sauer, 1955). A single multibranched female plant was found growing in ballast between railroad tracks.
- Artemisia scoparia Waldst. & Kit. - Asteraceae
Loc.: Evans Ave. near CN railroads, Vancouver. Nov. 15, 1990; # 90203.
A biennial plant which shows up as casual in various places outside its native range in Europe and Asia. A single plant along the road in an industrial area near railroad tracks. In North America it has been previously reported only from ore piles in Maryland (Reed, 1964).
- Bromus diandrus Roth - Poaceae
Loc.: South of Marine Way, Burnaby; May 26, 1992; # 92040.
European annual grass similar to Bromus rigidus, but generally larger and with a spreading panicle, not dense as is usual in B. rigidus. Growing in a rubble pile. Site is now an industrial park. In British Columbia, Pavlick (1995) refers to it as "reported from Victoria."
- Carex frankii Kunth - Cyperaceae
Loc.: Railroad tracks west of North Rd. near Brunette River, Burnaby; July 4, 1993; # 93085.

- Cicer arietinum - Fabaceae
Loc.: CN Railroads, east of Main St., Vancouver; Oct. 12, 1993; # 93317.
Although just about every commercial grain or seed plant will sprout up from time to time along railroad tracks (sunflower, buckwheat, lentil, soybean, corn, etc.), chickpeas are rare here. Many plants grew in disturbed sandy ground when the old Main St. railroads were being dug up.
- Conyza bonariensis (L.) Cronq. - Asteraceae
Loc.: Labatt's Brewery, Columbia St., New Westminster; Aug. 16, 1996; # 96139.

About 1/2 dozen plants showed up one year by the Greyhound Bus Terminal in New Westminster. Also collected on the shore of Lost Lagoon in Stanley Park where it probably arose from bird seed. Scoggan (1978) lists it from Nanaimo based on a specimen in CAN.
- Erechtites hiericiifolia (L.) Raf. ex DC. - Asteraceae
Loc.: Near Westwood Rd. & Kingsway, Port Coquitlam; Sept. 30, 1994; # 94230.
"A widespread American weed, occasionally introduced w. Cascades" (Hitchcock & Cronquist, 1974). A large plant producing ripe seeds was collected in disturbed ground at a railroad switch point in Port Coquitlam. Numerous plants were also found in a railroad switching area about 9 km southwest of this site in Coquitlam, but these developed too late to even flower.
