    While it's hard to pick indicator plant species there is something that many of the tropical plants share. That is a drip tip on the ends of the leaves (below). This pointed tip promotes drainage from the surface of the leaf, and thus helps keep the leaf surface clean of epiphytes and fungi in the humid forest.

  • Plants as indicators of gold mineralization at Watson Bar

    Elevated values of gold were determined in plants from specific sites which were often accompanied by high arsenic concentrations. As determined by neutron activation analysis, the highest gold concentrations (as much as 55 ppb) were found in the cyanogenic species P. sericca. This gold was lost by dry ashing the plant at 550 degrees C.
