hile visiting Hidalgo, I hitch-hiked a ride with the man who delivers the dynamite every morning to the mines in the Toliman canyon. He was very curious to see what amazing plant it was that brought this gringo all the way down into the canyon, so after he unloaded his delivery he and I drove deep down into the canyon, down the river bed. After a very narrow bend in the canyon, we encountered the famous colonies of P. agnata and P. elizabethiae. One colony of each, perhaps 20 meters from one another, but not mixing. In early September the P. aganta were just beginning to bloom, while P. elizabethiae were in full force. My friend the dynamite delivery man did not appreciate at all why I would find these little weeds of interest! Oddly, while the "Toliman Canyon" is a famous site for CP'ers, the locals in Zimapan don't recognize the name at all. No one in the city seemed to have ever heard of the canyon being called that.
It doesn't shock me that the locals didn't recognize the name. People (particularly those from Europe and the United States) tend to have their own official names for areas that have little to no relevance to people who actually live by or in those areas. The locals probably have their own name for the area, if any name at all.
Nothing compares to the joy of growing a plant from seed and watch it prosper.
Unfortunately, the short answer is "no" on sites near the US/Mexican border. Some species that are found in the northern reaches of the Sierra Madre Oriental might be reached in one day from the south Texas border; but you would have to spend at least a night there. But don't let that discourage you! There are very reasonably priced flights direct to Mexico City and / or Guadalajara (preferable) daily from many locations in the US, car rental is not horribly expensive, and driving (outside of Mexico City- I will never again try to maneuver my way through "DF" again!) is easy. Many Pinguiculas can be seen right along the roads, you just have to learn how to look for them.
Thanks for the reply. Darn, I'm from southern California so I thought maybe I could drive down there for a few days and look at Pinguicula. Oh well, guess there aren't any CPs within driving distance for me.
