Oh my ... y'alls photo's make me want to go plant shopping!
The only thing I've added to my collection this year is the recent purchase of a Pink Trumpet Vine:
Tiffany: Is that Kalanchoe in your photo the
Kalanchoe (Kalanchoe tetraphylla)
The one you show as Rhipsalis I at first thought was possibly
Rhipsalis elliptica but the more I look at your photo and the length of those leaves it looks more like
Queen of the Night (Epiphyllum oxypetalum) but once you get blooms the identify will be obvious.
Plants are so addictive and whenever I see pictures of one I don't have I think "I really need that!" Then I have to talk myself out of it because I have so many to take care of as it is.
