MAY MEETING NOSSA Member and Conservationist Doug Bickerton presented a most interesting and informative talk on the six Caladenia species (C. argocalla, C. behrii, C. gladiolata, C. macroclava, C. zantholeuca and C. woolcockiorum) and the six Pterostylis species (Pt aff nana from Hale Conservation Park, Pt. aff. boormanii from Halbury Scrub, Pt. aff. biseta from Mount Brown, Pterostylis despectans from Mt Bryan, Pt. bryophila and Pt. uliginosa) that he is researching. The orchids are either threatened or endangered. The talk was well illustrated with 35mm slides. An excellent presentation. Doug will be conducting natural pollination surveys this year on the twelve species that he is researching. Therefore, Doug would be most appreciative if you would refrain from hand- pollinating any of the above species without first talking to Doug. We can look forward to an update on Doug's research in a later Journal.
