Morphological characterization of the artificial hybrid between Stanhopea costarricensis and Stanhopea cirrhata (Orchidacea)
We report the production of a hybrid between Stanhopea costaricensis and S. cirrhata by artificial pollination. The hybrid plant and flowers are described. The flowers were normal and inherited morphological characteristics of both parent species. It is postulated that species of plants, like in the genus Stanhopea, that have very specific pollinators, have not evolved genetic mechanisms of isolation.
