Here is a photo! Sorry for the blurry image... It still gives the distinctive shape of the plant. http://i.imgur.com/fix6JC6.png Thank you!
Thanks for posting that, fstevens. Andrey, is that what this is? It's one I have unidentified at Kapi'olani Community College cactus garden in Honolulu.
Could be. I was just browsing google images and whenever I come to something close, it usually called E. lactea.
It's hard to say what it is from the photo. Something "cristata" anyway. cristata cristata image search euphorbia lactea cristata
