Abstract
Species Data
Species names follow the nomenclature in USDA PLANTS, with the exception of State-listed taxa (which follow the nomenclature of the Pennsylvania Natural Heritage Program). Species in red are non-native to the lower 48 States. Note: this likely will not be evident on copies printed in black and white. In this instance, refer to the 'Origin' field. Synonyms are those that appear in the various floristic studies at the GNA that were used in compiling the checklist. Species is said to be resistant or tolerant to deer. The species is said to be ant-dispersed and/or have seeds with elaiosomes. State-listed species (Pennsylvania Natural Heritage Program) Species with known alleopathic properties. Of specific value to native bees, bumblebees, honeybees, and/or predatory or parasitoid insects that prey upon pest insects. 'Wintergreen' species: Herbaceous species who's leaves emerge in late fall and are present throughout the winter. Note: The largest portion of the data comes from a study of the 'wintergreen flora' of Ohio, hence, some species that are categorized as 'wintergreen' may possess a different phenology in Pennsylvania. Spring ephemeral species.
