@LarryC, it looks like you have some decent sized plants there, great growing!
@coboro, Wow, really gorgeous Epi's! Love, love, love the pink one in your first photo that you refer to as The Beast!
Your plant in the 3rd photo reminds me a lot of
Hybrid Epiphyllum (Epiphyllum 'Fruhlingsgold')
I don't currently grow Epiphyllum but seeing all these gorgeous photos on this forum has me thinking I need a few!
