Myrmecodia platytyrea ssp. antoinii, an epiphyte from Southeast Asia with a symbiotic relationship with ants.
At next month's meeting of the Connecticut Cactus and Succulent Society, I'll be giving at talk about "Tropical Succulents." I'll be covering plants that grow in dry microhabitats in otherwise moist tropical forests, which sometimes have well-developed water storage tissues. Most of these rainforest succulents are epiphytes that grow without soil, clinging to branches high in the treetops. I'll have examples of myrmecophytes (ant-house plants) like Hydnophytum and Myrmecodia, orchids, jungle cacti like Rhipsalis and Selenicereus wittii, some unusual peperomias and hoyas, and others.
The meeting will be at Lauray of Salisbury, which will have a wide array of interesting succulents, begonias and orchids on sale. The trip through the Litchfield hills to Lauray should be nice in early October, too; I'd expect the fall foliage to be near its peak.
