Most twayblades and adder's-mouths are relatively small plants with tiny green flowers, but a few have richly colored blooms or particularly interesting habits that attract the native orchid enthusiast. Most of these species are easy to identify based upon their general appearance, range, and time of flowering. Answering three simple questions--when, where, and how does it grow?--and comparing the living plant with the striking photos in the backpack-friendly laminated guide should enable both professional and amateur naturalists to achieve the satisfaction of identifying a specific orchid.
