The first photo is of a pair of dracaena, fairly common. The tall one is commonly, and incorrectly, called "Lucky Bamboo". It's not really bamboo. Also, it's pronounced DRA-SEE-NA.

Next is a small cactus of unknown species next to a Crassula ovata "Gollum" my doctor was kind enough to give me.

This is just a large shot of most of the succulents and cacti. Basic Crassula ovata in the middle, with two Sanseveria on the left side.

This is a small pitcher from the Nepenthes alata. The pitcher is not a separate organ, yet a change in the leaf structure. This one has what I think are several fruit flies in the bottom.

Another dracaena, I forget what it's called. Something about having golden speckle leaves. Actually quite nice looking. Also some variegated "bamboo" and a mahogany sapling.
