Bryophyte collections

The Museum's bryophyte herbarium is among the largest and most comprehensive in the world.

The collection provides a unique source of critical data for the international bryological community, supporting research on taxonomy, habitat conservation and environmental monitoring over historical periods of time.

Geographical range.

Global:Arctic, boreal-temperate, tropical, austral-temperate, Antarctic

Temporal range.

Late 17th Century - 21st Century

Strengths of the collection

Most of the collections were accumulated by notable bryologists in the late eighteenth to early twentieth centuries. These pioneers of bryophyte taxonomy described thousands of new taxa from every continent, and consequently, the herbarium is rich in original material.

The herbarium is also rich in the specimens of pioneering early plant collectors, such as H. von Handel-Mazzetti, who collected in China, Humboldt & Bonpland in South America, GHK Thwaites in Sri Lanka and JD Hooker in Antarctica, India, and New Zealand.

Extensive recent collections of tropical and subtropical bryophytes have been made over the last 60 years, many by museum bryologists. Most significantly, these include material from Malaysia, Indonesia, the Indian subcontinent, the Seychelles and Mascarenes, New Zealand, and Ascension Island.

At home, in the United Kingdom, the Museum holds a large and ever-growing representation of British and Irish bryophytes, with collections ranging from historical to the contemporary.

Important historical collections

Herbarium holdings range from the late 17th Century through significant landmarks in the history of bryophyte taxonomy, incorporating many of the earliest local and exotic collections and reflecting historical changes in the processes and rules of botanical nomenclature.

Worthy of note

The primary type material of some of the hundreds of new taxa described by the 19th century German bryologist Carl Müller (Hal.)was destroyed in World War II, but duplicates of a significant fraction of his original material are held in BM.
