Hi! The bulbs and the attached leaves do appear to belong to a Coelogyne, but not the Coelogyne mayeriana in linked picture. The flowers pictured comes from a Coelogyne whose rhizomes (which connect the pseudobulbs) are unusually long -- about 1 foot long. I also have a Coelogyne mooreana whose p-bulbs are much closer to each other, and look to be more like the one you have. The flowers, however, are very different -- pure white. Unlike the C. mayeriana, the C. mooreana didn't like the move to Hawaii -- I believe (but I'm not certain) that it prefers intermediate temperatures for both growth and blooming.
