This is pretty great, a real botanizing effort to find and photograph all of the orchids native to Indiana, unless by now they are extinct! Here's the link to the U-tube slide show complements of the Get Your Botany On! blog (see the side bar). That's over 11 mins. of orchid pictures; hope you can stand it. One of the first pictures is Calopogon, the grass pink (note: it's neither grass nor a pink) and it looks upside down, but it's actually a right-side up orchid; almost all other orchids are resupinate, i.e., twisted 180 degrees on their flower stalks so that they are upside down. TPP has seen almost all of these, but over many years, and in many places. Enjoy.
