Orchid Diversity in Mediterranean-Type Climate Regions in the World

Dear Colleagues,

This Special Issue of Plants focuses on the fascinating diversity of orchids in regions with Mediterranean-type climates, which are renowned for their unique flora and high levels of endemism. The Orchidaceae family is a diverse group of plants and one of the most abundant among angiosperms, with over 28,000 species and 763 genera. Many of these species are endemic to small areas and are considered rare and endangered. Orchids also play diverse and ecologically significant roles in these ecosystems, of which they are often considered good bioindicators. This Special Issue aims to explore various aspects of orchid biology, including taxonomy, cytogenetics, conservation, hybridization, and ecological interactions, with a particular emphasis on threatened species and their conservation status.

We invite contributions that address the following themes:

• Orchid diversity, distribution, and endemism in Mediterranean-type climates;
• Cytogenetic and evolutionary studies of orchid species;
• Conservation strategies for threatened orchids and their habitats;
• Ecological roles and interactions of orchids in Mediterranean ecosystems.

We welcome original research articles, reviews, and perspectives that contribute to advancing our understanding of orchid diversity and conservation in Mediterranean-type climates.
