Oncidium nudum

After I got one of the electronic rodent repellent it has grown undisturbed. It bloomed last year and now has bloomed again. I was worried about the two weeks where the Southern Burner was waiting for parts. I had a 1500 watt electric going that didn't really get the job done for the warm to hot growers like this one.

Oncidium nudum grows in northern South America in hot, humid wetlands. It blooms in winter and has an inflorescence that extends almost two feet. The flowers last a very long time.

The spike started to develop in October. There are just a few more buds and it will be fully open. The spike is about six inches short of the two feet mentioned as proper spike length, but I am happy.
