The Fascinating Biology of Orchids
Monday, September 23 @ 7:30 pm - 9:30 pmFree
How has the family, Orchidaceae, become the most successful and largest family of flowering plants? Larry will discuss features of orchid biology that have led to a family that includes over 25, 000 species. Topics include pollination mechanisms, associations with beneficial fungi, adaptations to a wide range of terrestrial habitats, and how numerous orchid species have taken to the trees as epiphytes. The amazing diversity in floral forms has resulted in a multi-million dollar horticultural industry. As a result of their popularity, many orchid species have been and continue to be, poached from the wild. Because of this, and destruction of habitats, over 300 species are listed as endangered or threatened.
