Laelia anceps grows well and blooms well in cultivation. It grows in Mexico and Honduras. It is warm to hot growing, needs a dry winter rest and bright light. If it is dry it can winter outside if there is no hard freeze.
It is the perfect example of backbulb culture. There is the starting full-sized backbulb put in the pot of rocks. Over three generations it grew, each one larger. I expect the current new growth to be full-size again and probably bloom.
