What is an
Orchid?
Orchids are monocots which evolved 40 - 80 million years ago from a
lily-like relative. As a group, the orchid family is a young, rapidly evolving
family. Many species have complex pollination mechanisms, such as pollinator-specific
structures; these include parts for insect mimicry, pollinator traps, and/or
nectar rewards. These mechanisms suggest co-dependent relationships between
plant and pollinator.
Orchids occur on the ground (terrestrials), on rocks (lithophytes) and on trees (epiphytes). Epiphytes do not damage or derive any nutrients from
their tree hosts. All of Indiana's 43 species of orchids are terrestrial.
