Non-hardy gymnosperms from the Southern Hemisphere

The collection contains Coniferae and Cycadales from South America, Australia, New Zealand and South Africa. With an outstanding composition of specimens of an extraordinarily high quality, it documents the morphological diversity of this group of plants. A third of the species in this collection are listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora. The plants are regularly used for morphological and systematic studies, and they illustrate continental drift (Gondwana flora, living fossils).
