Specimen 1 I did not take notes on this one. The red berries reminded me of some Araliaceae, but I don't think it is. Any ideas? Sorry for the poor pic. The plant in question is the one with serrate, palmately compound leaves. See pic 1. Specimen 2 Petals 5, yellow, much longer than sepals Ovary inferior Flowers actinomorphic, solitary, whorled around nodes, bisexual, nodding Leaves opposite, simple, entire Stamens 5 Plant about 3 feet tall, herbaceous Found in a wet woods Stem square Petioles distinctly hairy See pics 2-4 Specimen 3 I did not take notes for this one, but it looks distinct enough to be ID'ed by sight. See pics 5-8 Specimen 4 Again, no notes, sorry. See pics 9-11. Found along a railroad track between a river and a beech-maple forest.
