The living collection, used by Renz as a research collection, is maintained
by the Botanical Garden of the University. It contains ca. 1'700 species
(represented by ca. 2'400 specimens), and is a representative collection of
mainly tropical epiphytes, although also containing some terrestrial and European
species. This is one of the finest collections of orchid species in Europe,
and has the potential to provide a resource for ex-situ conservation and propagation,
as well as providing valuable material to contribute to contemporary evolutionary
studies based on molecular systematics.
