Thanks John for the link to the habitat photos of the Amancay reserve in the Peruvian Lomas vegetation. Looks like they have really solved the problem of fading or blowing-away plant labels! 
  I was struck by the photo of a stone-carved label saying Tigridia grandiflora, which is usually considered a synonym of T pavonia. What is that species doing growing there? Is it native or was it introduced (like many plants) by the Inca in trade with Central American cultures? I imagine that it would have been a hot item, since it is edible. Has it evolved distinguishing features that differentiate it from the common forms of T pavonia? 
  T. pavonia is a common enough escaped plant in disturbed areas in Ecuador at 1800m, but the Peruvian lomas are much lower, much hotter, and much drier.  Anybody know anything about this plant?
