Quick Summary

The subtribe Pleurothallidinae refers to a large group of orchids within the genus Pleurothallis, native to the Americas. These orchids, often called bonnet orchids, are known for their attractive, hooded flowers. While many are epiphytes (growing on other plants), some grow on the ground. Their flowers typically display shades of yellow, white, red, green, or brown. Some species are cultivated for their beauty, while others are grown as novelties due to their diminutive size. The Pleurothallidinae subtribe is notable for containing over 4,000 species, making it a significant group within the orchid family.123
