Orchidaceae is a massive family of flowering plants that includes over 800 genera and estimates of up to 30,000 wild species. The number of catalogued hybrids is even larger.
The greatest diversity of orchids occur in the tropics. There are 300+ genera in the tropical Americas, but only 20 or so genera in North American. There are only 18 known species of native Orchids in Utah. Many of these are rare and getting rarer as we rapidly develop their habitat.
Although the number of orchids is massive, and this is one of the most beautiful plants on the planet; this particular gallery will probably not grow much beyond a less than inspiring collection of images of Bog Orchids.
