Who: Arthur Haines is a plant biologist specializing in the taxonomy and identification of New England tracheophytes. He is currently employed by the New England Wild Flower Society as a research botanist and is involved in writing a new tracheophyte flora of New England.  Lately much of his focus has been on hawthorns and he is preparing a revised treatment for New England.  Besides from being a highly recognized and astute botanist he is a skilled and approachable teacher.

What: This will be an advanced intensive weekend studying Crataegus of the central NY region. The weekend will consist of presentations, indoor study of specimens, and plenty of field work. Participants will learn the characters useful to identifying and distinguishing between the numerous species of Crataegus that occur in central New York. There will also be time to work on specimens that participants bring to study. Most of the confusion with Crataegus has been borne in the lab and not in the field (i.e. name proliferation and poor description of morphological characters) making this group inapproachable to most people. Hawthorn researchers have often used relative statements in keys, even when the features they were discussing could be objectively quantified. Using close-up  photography and clear wording, Arthur will try to help participants understand these features making it much easier to learn the species and groups within the genus.

When: Friday May 29th 7PM to Sunday May 31st 12 Noon, 2009.

 Where: Ithaca, New York. We will be based out of the Bailey Hortorium at Cornell University and will spend time both indoors and in the field in the Ithaca area.

 Cost: Cost includes the entire weekend program and a group dinner at a local restaurant Saturday evening. Other meals and housing are the obligation of the participants. Total cost is $95 for NYFA member or $120 for non-NYFA members. Participants are encouraged to become NYFA members ($20 membership/year). What to bring: a 10x hand lens is a must, field journal, appropriate clothing to be outside most of the day, Crataegus specimens, and bag lunches for Saturday (this can be purchased locally, in the morning).
