Hi All!
I'm hoping for some help with cactus ID. Have I got the labels right on these? Selenicereus anthonyanus and Epiphyllum anguliger? Thank you so much for any help!

They look correct to me.

Okay, thanks Tiffany!

I have not know the name of this plant until today when I came across it here. For years I have always called her my "PREHISTORIC PLANT" due to her looks. Whilst I have noted the actual name I think I will continue calling it my prehistoric plant as even my grand kids now know it as that. Mine has never flowered although I do recall my parents one did bloom when they were still around, white I think it was I am going to try the various tips and , well, lets see...

I am looking for various Disocactus Ackermannii in different colours. Anyone know where I can acquire? I have the deep red and snow white but now see yellows, mauve, pinks...all manner of beautiful colours. Any help would be appreciated. I live in Johannesburg, South Africa.

I don't know about this! I went and looked at my plant which came to me as 'Ric Rac Orchid Cactus'. It's showing both those growth forms. The problem for me is they are growing off the same stem-like structure. One on one side and one on the other. I'd say most of the growth more resembles what is seen in the top illustration, but there is some growth the is more like the lower illustration.

Makes it all really confusing!

I agree it's hard to tell them apart. I'm waiting for mine to bloom, as I've been told that's the best way. If it's white it's the Epiphyllum and if it's red with some cream petals it's the Selenicereus. Also from what I've read, I think the Selenicereus might be a little thicker and firmer than the Epi. I sure would love to actually be able to compare them. I don't think fishbone and ric rac are the best way to refer to them, as i've seen both names used for both plants. Most of these type plants also like to be somewhat root bound before blooming. They are night bloomers. I've had mine for two years, but it was already fairly large when I got it. I'm hoping for blooms next year. I think it's the Selenicereus, but not positive. Here's a picture of mine.

Look at all those air roots!! Such a cool appearing plant. Mine looks a lot like that. Bringing it inside for the winter is going to be a problem. It takes up a lot of air space and I'm short on space. Plants have to share that.

Common names often get applied to different plants. One of the big problems using them. In this case, I think the distinction in appearance would be to minor for anyone but a knowledgeable expert to differentiate. On the other hand, most folks would just be rolling their eyes at you if using the scientific terms. I know. I tend to use what I've learned first, whether it's the accepted name scientifically or one that's been changed and is no longer correct or the common name. It's really hard for me to switch from a name I've learned to something different.

Hi! New here! I just purchased this unique little guy from a local nursery. There was no ID on it other than Cactus.
With some quick google searches, I've figured out it is some sort of "zig zag" "ric rac" or "fishbone" cactus? I'm having some trouble confidently identifying which it looks to be and the correct care for it since I've seen two very different care instructions online. THANKS
