Begonia sp. Plant to the left, in pic is Sansevieria trifasciata. http://www.google.co.uk/imgres?q=Sa...100&start=0&ndsp=24&ved=1t:429,r:18,s:0,i:105
Plant near middle appears to be an Angle wing Begonia. Which I couldn't say. Check out the link below http://www.pbase.com/missy_gardenwhimsy/angel_wing_begonias
