These Orcliidese, and several more wbich correspond by their forms to those 

 of Europe, or are even identical with them, characterize all the subalpine re- 

 gions. The Orchidese are among the most characteristic plants, in a geographi- 

 cal point of view, for their forms vary in a striking manner, the more we 

 descend towards the warmer latitudes, where they assume more and more 

 brilliant colors, whilst their flowers become larger and more diversified.
