It is a pity we enjoyed today these flowers in Bloedel Conservatory and don't know their names. 1.Something just started to bloom 2. Bromeliads in bloom 3. Cactus? with transparent fruits 4. This is like a shrub on a long stalk 5. Tiny white flowers 6. It is a plant with 2 lobes leaves
Number 3 - I think I'm close if not totally there: How about Rhipsalis micrantha forma kirbergii? Here's the photo where I got that name: http://www.flickr.com/photos/80228239@N00/2614386627. There are some other Rhipsalis. Number 6 - a Bauhinia? I'd think you'd need to have more than just the leaves for an ID. I'm surprised no-one has answered Number 5. It's a common houseplant; I just can't remember the name.
I found Number 5: Pilea cadierei. Aluminum plant. I kept thinking the name had to do with some metal, but I was looking for iron something.
Wendy! I agree with 3,5,6 and I think 1 and 4 are the same plants. It is probably very popular plant, just I am not familiar with tropical plants Bromeliads are hard to identify without open flower
