Floral Trait and Mycorrhizal Similarity between an Endangered Orchid and Its Natural Hybrid

Hybridization can often lead to the formation of novel taxa which can have traits that resemble either or both parental species. Determining the similarity of hybrid traits to parental taxa is particularly important in plant conservation, as hybrids that form between rare and common taxa may more cl...
