Crenate Orchid Cactus (Epiphyllum crenatum)

Crenate Orchid Cactus
Epiphyllum crenatum

A new clipping in my garden

Xenomorf, what you have there is E. crenatum, not E. anguliger. E. anguliger looks like this picture below.

But my stems don't look like these:

or these:

they look more like this pict you posted here.

Xenomorf, I was referring to the picture of the cutting posted on June 17. Perhaps you could post a more current picture. I know that Epiphyllums can vary in their leaf shape, but the thickness of your cutting's lines isn't typical of the shape of E. anguliger. The wavy shape is representative of E. crenatum. I would be interested in seeing a current picture of this one of yours.

Here is my E. crenatum below. The shapes are irregular like your cutting above, and it also produces wavy leaves but not as indented as E. anguliger. E. anguliger on the other hand, rarely deviates in its leaf shape. E. anguliger wouldn't produce a shape such as you have above. E. crenatum, however, frequently has that shape.

Did the nursery that you bought that from identify it for you? If so, I believe it is incorrectly identified.

Here is another picture of my E. crenatum when it was little. You can see the resemblance here of my plant to your picture.

Here is E. anguliger. This plant has a cutting of Selenicereus anthonyanus stuck in it in the bottom right corner, which is a species with much deeper indentation and rounded ends.

By the way, E. crenatum flowers much more willingly than E. anguliger, and the flowers are much bigger as well. The flowers also look very different on the two so that is another way to tell them apart.

Here's a picture of E. anguliger again, showing consistent shape.

I've probably not explained it well. It's the irregular shape of your leaf there that makes it look like E. crenatum. E. anguliger has a consistent wavy shape for the most part. Here is a great link that shows both: http://www.ecology.org/tropicals/#Epis

I tried pulling up the ecology.org link you posted, but my security said it had a virus, so I couldn't access it.
My plant died that summer, it couldn't stand the heat.
It seems that you're more sure about this than I am about the identification, since you've grown more Epi's than me.
So yes, I authorize the movement of the photo to the correct page.

Thanks for working this out. The photo has been moved.
