Upon stimulation, plants elicit electrical signals that can travel within a cellular network analogous to the animal nervous system. It is well-known that in the human brain, voltage changes in certain regions result from concerted electrical activity which, in the form of action potentials (APs), travels within nerve-cell arrays. Electro- and magnetophysiological techniques like electroencephalography, magnetoencephalography, and magnetic resonance imaging are used to record this activity and to diagnose disorders. Here we demonstrate that APs in a multicellular plant system produce measurable magnetic fields. Using atomic optically pumped magnetometers, biomagnetism associated with electrical activity in the carnivorous Venus flytrap, Dionaea muscipula, was recorded. Action potentials were induced by heat stimulation and detected both electrically and magnetically. Furthermore, the thermal properties of ion channels underlying the AP were studied. Beyond proof of principle, our findings pave the way to understanding the molecular basis of biomagnetism in living plants. In the future, magnetometry may be used to study long-distance electrical signaling in a variety of plant species, and to develop noninvasive diagnostics of plant stress and disease.
I picked this up at the Houston Orchid Show in 2019, it’s mid May 2020 and it has its first blooms. the blooms have a strong, sweet smell, which should be obvious given its name. I’ve found it needs far more water and sun than the usual house orchids. This window gives it strong morning sun for several hours in all but the winter months.
Gongoras were first mentioned in the mid 1800s after being discovered by Spanish explorers in their native Ecuador, Columbia and Venezuela.
Gongoras are true epiphytes, I find growing epiphytes in semi-hydro works extremely well. ( a clear shallow bowl, pebbles and about 1″-2″ of water keep in the bottom of the container ). As you can see from the tips of the leaves, it found the winter too dry in here, even in Houston. It’ll probably need a greenhouse in drier parts of the world. It also loves warmth, There is no winter hibernation for this orchid.
Gongoras like the rest of the Stanhopeinae subtribus grow large, this one has doubled in size in a year and I hope it’ll continue to do so for several years. Blooms come in the spring.
They are pollinated by solitary male bees, solitary bees are native to the Americas, the hive bees were imported by the Europeans.

… more photos and info as it gets larger and I learn more about it
