Members’ reports on summer botanizing
At the first of the Philadelphia Botanical Club fall meetings, members are invited to share photos and news from our botanizing during the summer. We would like to see your photos!
If you are planning to show your photos at the meeting, please have them ready to email by noon on the 24th. If possible, consolidate your photos into a single PDF or PowerPoint file, but individual photos are also OK. We ask that you limit your slides to a maximum of 6, and your comments to at most 6 minutes.

Pond Scum Diaries: Connecting green algae, the origin of land plants, and an iconic collection at the Academy of Natural Sciences

Dr. Richard McCourt, Botany Curator Emeritus of Botany at the Academy of Natural Sciences of Drexel University, has spent his career investigating the diversity and evolution of green algae. He also has a long-standing interest in the plant collection of the Lewis and Clark expedition, made on their iconic expedition in 1804-06, now housed primarily at the Academy of Natural Sciences. His talk will combine both themes, with an overview of the conjugating green algae such as Spirogyra and its relatives and their relationship to land plants, and a report on algae encountered on the Lewis and Clark expedition. He will also report on a recent find of some surprising Lewis and Clark specimens in London.
