Common Name is Lady of the Night Orchid
Brassavola is a genus of 20 orchids (family Orchidaceae).
The name comes from the Venetian nobleman and physician Antonio Musa Brassavola.
These species are native to the lowlands of Central America and tropical South America.
They are epiphytes (an organism that grows upon or attached to a living plant.)
Most Brassavola orchids are very fragrant, attracting pollinators with their citrusy smell.
But they are only fragrant at night, in order to attract the right moth.
In 1698 Brassavola nodosa was the first tropical orchid to be brought from the Caribbean island Curaçao to Holland.
Thus began the propagation of this orchid and the fascination for orchids in general. (Wikipedia)
I cut this specimen from the mango tree in my back yard.
