TWO PLANTS NEW TO THE FLORA OF BRITISH COLUMBIA
From: Hans Roemer <hroemer at galaxy.gov.bc.ca>
During field work for the BC Conservation Data Centre this past
summer I had the privilege to record occurrences of two vascular
species that were new to me and are apparently new to the BC
TRICHOSTEMA OBLONGUM (Labiatae-Lamiaceae) has up to now remained
unmentioned in the provincial botanical literature. Hitchcock
and Cronquist (1973) give the range of this plant as "Wn and
adj Ida to Cal and W Nev".
Trichostema oblongum Benth. is a small, annual member of the
mint family (Lamiaceae) with strongly aromatic, oval leaves
and small blue flowers in the leaf axils. Distinctive fea-
tures of the plant are the odd upward bend of the flower and
the bundled style and filaments arching over the corolla from
the back. Our plants were only 2.5 to 5 cm tall at flowering
time. Collections and photographs of this species were ob-
tained by Ron Walker and myself on July 12, 1996, ca. 10 km
west of Castlegar. The habitat was a vernally moist site
within a large, south-facing forest opening caused by shallow
soils over bedrock. Trichostema grew in a carpet of moss
(Aulacomnium androgynum) together with scattered Cystopteris
fragilis, Juncus cf. bufonius, Perideridia gairdneri,
Dodecatheon pulchellum, Deschampsia danthonioides, Mimulus
guttatus, Orobanche uniflora, Lomatium spp., etc. Other rare
species in the same opening, but not directly associated with
Trichostema were Heterocodon rariflorum, Mimulus breweri,
Botrychium simplex and an as yet unidentified terrestrial
ERIGERON OCHROLEUCUS VAR. SCRIBNERI (Compositae-Asteraceae) was
reported by Henry (1915) to occur in British Columbia.
However, "no collections are known to date" (Douglas, 1989).
Douglas included this taxon in his treatment of the As-
teraceae of BC as "yet to be collected in British Columbia",
as it is known from several stations just east of the
BC/Alberta border (Douglas, 1995).
Erigeron ochroleucus Nutt. is a linear-leaved, smallish
fleabane (our specimens ca. 8 cm tall) with short, grayish
foliage, a single, large head, and woolly involucral bracts.
The short ray flowers are variably light coloured (in our
specimens light blue). Our plants belong to var. scribneri
(Rydb.) Cronq. Jenifer Penny and I collected this plant in
the Rocky Mountains on the south- and southeast-facing slopes
of Mt. Gass between 2300 and 2500 m elevation. The plants
were consistently found on wind-exposed, stony limestone
slopes bearing only a short, discontinuous cover of vegeta-
tion. Associated species on these dry sites were primarily
Dryas octopetala and Kobresia myosuroides, sometimes also
Erigeron grandiflorus, Townsendia parryi, Oxytropis sericea,
and Antennaria alpina.
Any information on these two species from British Columbia would
be appreciated by the author <HROEMER at galaxy.gov.bc.ca> or the
BC Conservation Data Centre <GWDOUGLAS at fwhdept.env.gov.bc.ca>.

1793: JOHANN FRIEDRICH ESCHSCHOLTZ is born at Dorpat, now Tartu,
Estonia. Following education at Dorpat University, now Tartu
University, Eschscholtz will serve as naturalist and physician
on Kotzebue's voyages around the world from 1815 to 1818. His
specimens from the voyage will be given to Dorpat University,
and he will become curator of the Dorpat zoological collections
1880: ALFRED LOTHAR WEGENER is born in Berlin. In 1912 he will
read a paper titled "Die Herausbildung der Grossformen der
Erdrinde (Kontinente und Ozeane) auf geophysikalischer
Grundlage" ["The geophysical basis of the evolution of large-
scale features of the earth's crust"] before the Geological
Association of Frankfurt am Main. It will be expanded in 1915
into "Die Entstehung der Kontinente und Ozeane" ["The Origin of
Continents and Oceans"], the first comprehensive account of the
theory of continental drift. On this day in 1930, his fiftieth
birthday, while on an expedition to Greenland, Wegener will
leave his base camp for the western coast and will not be seen

UPROAR ON THE LICHENS-L DISCUSSION LIST AND REQUEST FOR SUPPORT
From: "Professor David Richardson, Dean of Science"
<DRICHARD at Science.stmarys.ca>
I received a note from Sylvia Sharnoff thanking me and others in
the lichen discussion group for help on her National Geographic
article. She asked me whether we could give her some more and
urgent help. As many of you know Steve and Sylvia Sharnoff are
collaborating with Ernie Brodo to produce a richly colour-
illustrated book on Lichens of North America.
The Middle Management of the Canadian Museum of Nature
have declared that guidebooks must be fully funded from
outside sources and have forbidden Ernie to finish it
except on his own time. They have also cut contract nego-
tiations with Yale University Press. Ernie will be meeting
the Interim President of the museum Mr Colin Eades on
November 7th. Between now and then we need to generate as
much support as possible.
If you are willing, Please E mail or send a letter of
Mr Colin Eades <ceades at mus-nature.ca>

Request for funding for "Lichens of North America"
For the past three and a half years, Irwin M. Brodo of the
Canadian Museum of Nature (CMN) has been working with California
photographer/lichenologists Steve and Sylvia Sharnoff on a
popular, illustrated guide to the lichens of North America. The
plan is to produce a treatment of 790 illustrated macro- and
microlichens, with comparative notes on many others. Descrip-
tions, keys and distribution maps would be provided for each
illustrated species. Introductory chapters would cover morphol-
ogy, chemistry, phytogeography, uses, methods for lichen study,
and basic classification.
The CMN policy regarding the production of guidebooks, requires
researchers to completely fund such projects from outside
sources to cover all operational and labour costs (i.e., includ-
ing salaries of all staff working on the book). In the case of
the "Lichens of North America" project, the remaining work is
estimated to cost CAN$53,540 (ca. US$40,000). Work on the book
may not proceed until the complete funding is in place.
At this point, all the photography has been completed and the
photographs selected. The introductory chapters are in 1st draft
stage (130 pages). Species treatments are complete for 219
species, and the writing of keys has begun. Data for almost all
the distribution maps have been gathered, and final maps have
been drawn for ca. 260 species. It is estimated that about nine
months of additional work is needed to complete the manuscript.
Donors or supporters will, of course, be acknowledged in the
book. Anyone knowing of potential sources of funding is urged to
contact the museum's Grants Officer, Ms. Martha Johnson,
Canadian Museum of Nature, P.O. Box 3443, Station 'D', Ottawa,
Ontario K1P 6P4, with a copy to Irwin Brodo, Research Division,
at the same address.
From: Darrell Wright <dwright at emf.net>
Lichen students the world over are groaning at the decision of
the Canadian Museum of Nature to withdraw support for Dr.
Brodo's efforts to bring The Lichens of North America book to
publication. It is particularly needed at this time as a tool
for conservationists who, with the help of excellent materials
like this, will eventually be able to obtain regulatory protec-
tion for these remarkable organisms. It would be a first class
tribute to the Canadian Museum of Nature to help with its publi-
cation. Please ensure that the Museum supports this effort.
