A large flowered species from Sichuan Province, and described in 1998. Close to E.membranaceum, the large flowers have the narrow sepals and long petal spurs
pressed close together like a single structure, and the petal lamina reduced to insignificance, so the whole thing is just four long curved horns.
I have two clones of the species. This one is slightly paler and has less extravagantly horned flowers.
This is the second clone of the species that I grow. Collected by Mikinori Ogisu under the number OG 92114, it is deeper yellow and oozes like exotic glassware
or something that fell out of a lava lamp.
