BOTANY BC '97 - AUGUST 1ST TO 3RD, 1997, CATHEDRAL LAKES

The  BC Conservation Data Centre is organizing this year's meet-
ing and we are excited to offer an opportunity to do  some  high
country  botany at Cathedral Lakes Park. We have booked space at
Cathedral Lakes Lodge,  and  space  is  limited  in  the  lodge,
chalets,  and  cabins.  There are camping sites in the park, and
the lodge can accommodate limited numbers of campers for  meals.
We  are still working on the details, but the registration forms
will be mailed out early next week.


ACAULON - A NEW BRYOPHYTE GENUS IN BRITISH COLUMBIA
From: "D. Ross Priddle" <yb396 at freenet.victoria.bc.ca>

One Sunday afternoon in February of 1997 I went for  a  walk  at
McNeil  Bay,  Victoria,  B.C.  I walked east and north along the
rocky shoreline. A ways along (before the point) and  back  from
the  shore  at  the  vegetation margin on the sandy soil beneath
small shrubs I discovered a tiny bulbiform moss  which  appeared
to  have  included  sporophytes.  I collected a small sample and
later  identified it  as Acaulon muticum var. rufescens  (Jaeg.)
Crum.  I  sent  the  specimen  to Dr. R.H. Zander at the Clinton
Herbarium in the Buffalo Museum of Science, New York  (BUF)  who
confirmed my identification and deposited the specimen there.

This  moss has not been previously reported in British Columbia.
Crum & Anderson (1981) illustrate this taxon and give the  range
as  "Quebec  to  Michigan, Iowa, Kansas and south to Florida and
Texas; California and (according  to  Grout)  Arizona."  On  the
Canadian  Checklist (Ireland et al., 1987) the taxon is verified
only for Ontario, with literature reports from  Quebec and  Sas-
katchewan.

Dr. Zander is the recognized expert on Pottiaceae and is working
on  the  treatment of Acaulon for the forthcoming Flora of North
America. He offers this key:


1. Leaves awned; laminal cells papillose abaxially
   .............  1. Acaulon schimperianum (Sull.) Sull. & Lesq.

1. Leaves cuspidate or blunt; laminal cells smooth.

   2. Plant  often  three-angled,  about  1.0 mm  high;   leaves
      keeled; seta about as long as the diameter of the capsule;
      spores about 30 um, finely papillose
      .....................  2. Acaulon triquetrum (Spruce) C.M.

   2. Plants  flattened-globose  or three-angled; leaves broadly
      channeled; seta short,  about  0.3  the  diameter  of  the
      capsule; spores 30-50 um, smooth or papillose
      .........................  3. Acaulon muticum (Hedw.) C.M.

      3. Spores  shortly  ellipsoidal, brown, densely papillose-
         roughened
         .....................  3a. Acaulon muticum var. muticum

      3. Spores nearly spherical, yellow, smooth
         ......  3b. Acaulon muticum var. rufescens (Jeag.) Crum

Acaulon muticum var. muticum seems to be rare in North  America,
although  it  is  more  common  in  northern and central Europe.
Acaulon muticum var. rufescens seems to be common plant in parts
of North America (see above).

BRYOLOGICAL EXCURSION, 10 MAY 1997, SWAN VALLEY, MONTANA
Toby Spribille <Spribille_Toby/r1_kootenai at fs.fed.us>

A  bryological excursion day is planned for 10 May 1997 near the
northwest Montana  town  of  Bigfork,  led  by  Drs.  Dale  Vitt
(University of Alberta, Edmonton) and Lars Soederstroem (Univer-
sity  of  Trondheim, Norway). The object of the field trip is to
bring together people with interest in mosses and liverworts  to
meet  and  exchange ideas and information while inventorying the
bryoflora of the bottoms of the Porcupine  Creek  drainage  just
southeast  of  the town of Bigfork in the beautiful Swan Valley.
This is an area with high  species  diversity  and  many  unique
phytogeographic  elements,  including  boreal and coastal. There
are several calcareous fens in  the  area.  The  excursion  will
include  guided  visits to these unique habitats as well as sur-
rounding upland terrain.

Excursion participants will meet at the  Forest  Service  Ranger
Station  in Bigfork at 8:00 AM on the morning of the 10th of May
and will carpool to go to the  field  sites.  The  excursion  is
planned to last until about 4:00 PM. Participants are advised to
bring  raingear and rubber boots, a boxed lunch, collecting bags
and hand lenses.

Accommodations and restaurants are found in abundance in Bigfork
and nearby Kalispell.

Registration is free of charge. To register, please provide your
name, mailing address (incl. e-mail!) and phone/fax to

vicinity maps to registrants to help them plan their attendance.

ORCHIDS OF THE OTTAWA DISTRICT, ONTARIO, CANADA
From: Marilyn Light <mlight at aix1.uottawa.ca>

Reddoch, Joyce M. & Allan H. Reddoch. 1997. The orchids  in  the
   Ottawa   District:   Floristics,  phytogeography,  population
   studies and historical review. Special Issue of The  Canadian
   Field-Naturalist, vol 111, no. 1: 1-186.

This  186-page  work  describes  the 44 orchid species that have
been found within 50 km of Canada's National  Parliament  Build-
ings  in Ottawa. It contains information on identification, past
abundance, population changes, development cycles  and  relative
stability  of colonies. It is presented as a baseline study from
which to design further research and prepare effective  planning
measures to protect wild orchid populations.

The Introduction describes the history of collecting and record-
ing  since  1856,  principal orchid habitats, local distribution
patterns, rare species, colour forms, capsules and seeds, bloom-
ing dates and other topics.

Each species account provides detailed information on the  above
topics,  as  well as a brief description of the plant. A drawing
and a spot distribution map accompany each account. Correlations
of some species with the Canadian Shield  or  the  St.  Lawrence
Lowlands,  or  with  calcareous rock, sandstone or sand deposits
are shown. Long-lived colonies of many  species  are  described,
and  population  studies  are included for Corallorhiza striata,
Goodyera pubescens, G. tesselata, Platanthera  hookeri,  P.  or-
biculata and Spiranthes cernua.
