Plants Seen in Peru:

This beautiful fern-like plant was seen on the hike up to Waynapicchu

This plant was seen at Machu Picchu and has attractive lavender flowers. I would guess some type of
terrestrial orchid, a very large one at that.  This reached six feet tall.

These next 3 plants were seen in the Amazon Jungle part of Peru.  They look as if they could have potential as house plants.
