I received this Epi several years ago as a bonus I received in an order of cuttings. It bloomed this past year, but for the life of me, I can't find the tag or remember the name. Does anyone know what cultivar it might be?

This is the bloom:


Here you can see some of the leaf with the bloom:

The narrow petals remind me of Hooker's Orchid Cactus (Epiphyllum hookeri)

Ooo, Lin, I think you're right! I'd forgotten that difference in the bloom! *Blush*

I used to have huge plants of both and remembered the oxypetalum had wide petals and the hookerii had narrow petals. They are both apparently very fragrant (especially E. oxypetalum) but I have a weird nose and have never detected much scent. My husband says they smell really good! Green Grin!

Lin is correct ! Epiphyllum hookeri, aka Epiphyllum strictum.

Ursula, thanks for the confirmation! I wasn't real sure since I couldn't see the pistil (or whatever that pink part of the bloom is called.) Green Grin!

Linn and Ursula (and all) - I skimmed through photos doing a search of white blooming epis and thought it might be Epiphyllum hookeri, but I did NOT remember that name as one I had received. When Ursula said "Strictum", I immediately remembered that name and said THAT'S IT!!!! Thank you, thank you, thank you! It was bothering me something awful that I remembered the few cultivars I had received except THAT one plant. Whew.... I was hoping someone here would mention a name that would ring a bell for me. Thanks for your help in IDing this epi for me!!!!

I have several oxypetalum, so I knew it wasn't that one. And I will concur that the scent of oxypetalum is one of the most intoxicating flower scents I have ever smelled in my life. BUT .... the scent is only present at the height of it's bloom which for me is right around midnight during that single night. Before and after that time .... the scent is not there. My guess is that detectable scent is when the bloom is most fertile and the scent may attract the pollinators. The blooms on Epiphyllum hookeri are too high in the air hanging from my large arbor/pergola for me to smell and it usually blooms at the same time as oxypetalum so I can not distinguish a scent of that cultivar/species. I might have to stand on a chair and cut one of the blooms off to smell it to see if it too is scented. I love these plants! It is an EVENT when they have their bloom flushes several times a year!

Thanks for the correct ID!!!! I really appreciate it! Thank You! Thank You! Thank You! Thank You! Thank You! Thank You!

I had mine ID'd on DG years ago and I forgot that it had a synonym of strictum. Smiling

Becky, don't forget to add your photo to the DB. Green Grin! Hooker's Orchid Cactus (Epiphyllum hookeri)

According to The Plant List, strictum is indeed a synonym of hookeri.

I submitted a proposal to list that synonym in this plant's DB entry here.
