Anguloa dubia

Anguloa dubia, taken from the front of the flower.  Anguloa dubia produces a profusion of five or six, yellow, scented blooms (per bulb!) that are a bit smaller than other Anguloa species but make up for it in numbers.  The frangrance has been described as alternately like Wintergreen oil or perhaps lemon oil, in either case, fairly pleasant.  In San Diego it blooms in the February/March timeframe, similar to the season in its native Columbia.  They seem to grow outside in San Diego without issue although a bit of protection from the cold Winter rains is probably a good idea.

Ida fragrans

Ida fragrans, a native of Ecuador and Columbia where it grows at around 5000 ft., blooming in the greenhouse.  True to Oakeley's description, it has the fragrance of hyacinths at night (yes, I had to go out into the greenhouse at night to smell it to see if it was really true!).  Much thanks to Dr. Henry Oakeley for the very helpful description (and the autograph on my copy of Lycaste, Ida and Anguloa).  Notably, the picture of Ida fragrans in Orchidencyclopedia.com appears to be of something else (which ultimately forced me to look things up in Oakely, which I should have done in the first place).
