Some plants just don't want to be classified by humans without putting up a good fight. Here are some examples of really amazing variations of Cactus Plants found in NW Argentina.


These Soehrensia plants are growing within 50 miles of one another. the first set of pictures is what we normally look for as Soehrensia bruchii. The next grow on another hill not 5 miles from the first. The third is of plants that grow about 40 miles away, but over a ridge and in a pass that provises growing condiditons that are more humid. The pass elevation traps moisture in the form of fogs and low clouds frequently. thus the softer growth form and more red color of the flower.
These have decidedly yellow flower parts.
These have very few spines and the flower color is red, not orange.
