whitewind Posted November 9, 2012 Labelled 'Epiphyllum' but has narrow, 3-ribbed stems. The flower is about as large as my outstretched hand from thumb to little finger. 3 Share this post Link to post Share on other sites
0 Sallubrious Posted November 9, 2012 I was going suggest Hylocerus, but it doesn't quite fit the bill. Share this post Link to post Share on other sites
0 Mr. Bowser Posted November 9, 2012 Looks kinda like a selenicereus flower to me, but the stem looks very much like a hylocereus. I wonder if hybrids between the two are possible. Share this post Link to post Share on other sites
0 shortly Posted November 9, 2012 I have a several different Epi's that swing back & forth between the 2 growth forms, sometimes on the same stem, i just put it down to environmental factors. Share this post Link to post Share on other sites
0 Stillman Posted November 9, 2012 (edited) Looks like the big old Night queen flower to me? Epiphyllum oxypetalum ( I know it can't be but I bet there is some of its genetics amongst it). Apparently they interbreed shockingly. We have a heap of different species all next to each other and pods on everything. From my understanding none are self fertile so I image I will have some interesting Hybrid seed in a month or so. Edited November 9, 2012 by Stillman Share this post Link to post Share on other sites
0 whitewind Posted November 11, 2012 This is a wild collected plant from South America so if is a hybrid it is a natural one. I haven't seen any other type of growth form on that plant, although I have seen other Epi's change growth habit a bit. It's not setting any fruit, sadly.

0 Jox Posted November 21, 2012 Hey whitewind, That looks a lot like selenicereus megalanthus (yellow dragon fruit), the stems, flowers location were it was collected all fit. HURRY UP & FRUIT!!! Share this post Link to post Share on other sites
0 whitewind Posted November 21, 2012 Won't self! No fruit set. The stems don't quite look like dragonfruit, softer but fuller in cross-section (as in properly triangular), much narrower (about 1cm across) and no spines at the nodes. Share this post Link to post Share on other sites
0 Jox Posted November 21, 2012 Can you get more photos of the plant? S. megalanthus can be quit variable, I have cuttings here that look very similar to yours & I'm positive of there ID because we ate the fruit the same day I took the cuttings. Need to see more pics, I will take some on in a couple of days & put them up here for you to compere. Cheers jox Share this post Link to post Share on other sites
0 whitewind Posted November 21, 2012 Cactus flowers get me off ! Alright Jox I will try and get some close-ups it may take a couple of days. All the flowers come in waves, last time I saw it there was nothing. Share this post Link to post Share on other sites
0 zelly Posted November 22, 2012 It's definitely not a selenicereus megalanthus, pictured below: with greenish sepals & skinny white petals, it looks somewhat like a hylocereus minutiflorus or hylocereus escuintlensis, both pictured in The New Cactus Lexicon, 2006 Edition Pics of the floral tube would help 2 Share this post Link to post Share on other sites
0 Jox Posted November 23, 2012 Sorry! Bad call on the flower , my apologies. Share this post Link to post Share on other sites
0 whitewind Posted December 21, 2012 Eek it caught me by surprise today, went to take some cutting and caught my hand on an old dead flower, covered in spines. I didn't think Epi's had spiny fruit - maybe that will help with the ID? Share this post Link to post Share on other sites
0 whitewind Posted December 21, 2012 So, like, does the vestigial spination on some rainforest cacti mean that they are more recently developed species, or did the whole desert cacti thing evolve as an offshoot from plants which already produced spines for protecting the fruit and some species stems? I reckon it's the former, is there any written research done on this already, anyone know? Share this post Link to post Share on other sites
