January 17 (Sunday)
Botany in the Winter: Nottingham County Park, Chester County, PA
Nottingham Park, encompassing one of the largest of Pennsylvania's State Line Serpentine Barrens, contains one of the richest floras in southeastern Pennsylvania, including a plethora of woody species. Our goals are first to see how many species we can identify at this time of year using identifying marks such as buds, bark, old leaves, and remnant fruiting material, and second to learn how to identify plants when they are not in leaf or flower.
Directions: The Park Headquarters is 150 Park Road, Nottingham, PA 19362. We will meet in the main parking lot.
Leaders: Jack Holt and Janet Ebert, (610) 459-0585, email

Unionville Barrens, Chester County, PA
Joint field trip with the Muhlenberg Botanical Society
One of Pennsylvania's highest-quality serpentine barrens, the Unionville Barrens finally received long-sought protection in 2008 from Natural Lands Trust as part of the nearly 1,100-acre ChesLen Preserve. The grasslands and blackjack oak-post oak woodlands are remnants of a landscape managed for centuries by American Indians using fire. With fire exclusion, the species-rich serpentine grasslands have shrunk from nearly 60 acres in 1937 to less than 9 acres today. The loss in area has led to species extirpation: 16 state-listed species occur there now but 4 more seen historically are gone. N.L.T. plans to restore and maintain at least 40 acres of oak savanna. A 2005 report, "Protecting the Unionville Barrens" (available at Roger Latham's web site under Publications) describes the site's history, flora and ecology. Appendix A is a survey by Janet Ebert listing 174 vascular plant species. We will see the globally rare serpentine aster (Symphyotrichum depauperatum) and many species in flower or fruit, likely including Carex bicknellii, C. richardsonii, Deschampsia cespitosa, Dichanthelium oligosanthes, D. villosissimum, Helianthemum bicknellii, Packera anonyma, Quercus nigra and Scleria pauciflora. Meet at 1 PM. Wear footgear suitable for wet walking.

Program: Field trips, by bus, will include Mt. Greylock, the highest mountain in Massachusetts with its own unique sub-alpine boreal forest and rare plants, and Bartholomew's Cobble, National Natural Landmark, which has one of North America's greatest diversity of fern species and many interesting plants amid the unusual geology of the cobbles. Other trips will depend on the best botanical locations at the time. There will be a variety of evening lectures. Leaders are Pam Weatherbee, Berkshire County Botanist, and Dr. C. Barre Hellquist, Biology Professor Emeritus, Massachusetts College of Liberal Arts.
Housing, meals, and cost: Accommodations are in the school dormitory rooms, though other options are available (see the invitation for details). The price of the field meeting will be $350 including four nights lodging and meals from Sunday night thru Thursday breakfast.

July 22 (Thursday), 7:30 to 9:30 PM
Fern Identification Workshop
Southeast Pennsylvania and New Jersey offer a high diversity of fern species, and ferns are becoming an ever more important part of our flora (since they are largely unaffected by deer browsing). In this workshop, you can learn to identify the characteristic ferns of our area. The workshop will cover both woodland ferns (such as lady fern, silvery glade fern, and the woodferns) and rock-dwellers (such as purple cliffbrake, blunt-lobed woodsia, and the bulblet and bladder ferns). The emphasis will be on learning characteristics to identify ferns in the field. By examining fresh frond specimens, you can learn the characteristics needed to identify ferns in the field. In addition, microscopes will be available so that you can get a good like at the fine details, such as glands and sori. If you have a fern you want identified, bring a frond to the workshop.
Registration: The workshop is open only to members of the Philadelphia Botanical Club. Space is limited, so you must register with the leader, Janet Novak, at 215-248-2642 or
Location: The Academy of Natural Sciences in Philadelphia
