Predicting the flowering times of angiosperm taxa is a goal of mounting importance in the face of future climate change, with applications not only in plant biology and ecology, but also horticulture, agriculture, and invasive species management.

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

The Plant Phenology Ontology (PPO) was originally developed to integrate phenology observations of whole plants across different global observation networks.

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.
