Speaker/Topic/Location: TBD

VERY LATEST: The San Francisco Orchid Society has invited the SF Fern Society to sponsor a table at their upcoming Orchids in the Park event on July 27 and 28. Of course we've accepted and will display an assortment of special ferns (and a few orchids to round out the display). You might want to stop by during the weekend to see the brilliant orchid and fern displays -- and perhaps shop for a special orchid (or even a fern!) to take home. See for details.

EVEN NEWER: KQED Deep Look with production/research assistance from the UC Botanical Garden at Berkeley (and one of our officers!) created this delightful short (3:44) video about fern reproduction:

NEWER: The presentation archive page is now up to date. We recently added Wendy Born's slideshow on spore propagation from the February 2024 meeting, Tom Mudge's presentation about Ferns of New Zealand from the May 2023 meeting, and Dan Yansura's presentation about the Polypodiaceae Fern Family from the November 2023 meeting.

NEW: Alex Adams provided a link to the short video (37 seconds) he talked about at the May 2022 meeting. From Alex: "It is of my Lecanopteris mirabilis doing what ant ferns do, providing a home for an ant colony. The video recorded me telling my wife that they are attacking my hand and my phone and that I was turning it off. They really do provide a good defense for the plant!"

Slideshows from past meetings have been moved to their own page because this page was looking way too cluttered.

Two pages are under construction: a fern photos page and a links page.
