Plant biodiversity is threatened, yet many species remain undescribed. It is estimated that >50% of undescribed species have already been collected and are awaiting discovery in herbaria.

We partnered with various federal, state, and private interests to evaluate the floristic composition at the Garden City Terminal of the Port of Savannah, Georgia, USA.

Plant phenological responses to global warming are well studied. However, while many locations are experiencing increased temperatures, some locations are experiencing climate cooling.

Natural history museums are unique spaces for interdisciplinary research and for educational
innovation. Through extensive exhibits and public programming and by hosting rich

Davallia solida (G. Forst.) Sw. (Davalliaceae), Phlebodium aureum (L.) J. Sm. (Polypodiaceae), Phlebodium pseudoaureum (Cav.) Lellinger (Polypodiaceae), and Rumohra adiantiformis (G.

Studies in plant phenology have provided some of the best evidence for large-scale responses to recent climate change.

Herbarium specimens are increasingly recognized as an important resource for conservation

Major international herbaria, natural history museums and universities have recently begun to digitise their collections to facilitate studies and improve access to collections.

The Systematics Collections Committee of the American Society of Plant Taxonomists has updated the recommendations on herbarium practices and ethics that were previously published by the Society in 1958 and 1973.

This Online Herbaria Guide was assembled by the Plant Nomenclature & Taxonomy Community. It provides a list of herbaria for research purposes.
