For more information on the habitat and vegetation of Ravenna Park and on the weather of the day this was observed, please see the journal entry for April 24, 2012 here on iNaturalist. This fern was growing all over Ravenna Park and some of the plants did not have all of their fronds completely unfurled yet. The fern I observed was about 3 feet tall and had at least 15-20 different fronds. Each little leaf on each frond was divided into many smaller parts, as shown by the up close picture I took.
