I received this in a trade several years ago as Bulbophyllum evrardii. It isn't even close although it looks like the photo on IOSPE and Jay says it is NOT evrardii. The little "fishing poles" on the dorsal sepals bounce around with any air movement perhaps to lure the pollinator (?). Anyway, I'm thinking perhaps B. amplifolium, picturatum or pseudopicturatum. I am open to suggestions. I wouldn't rule out a hybrid but would be surprised. The flowers are about 2 inches long, largest pseudobulb about 2 inches and the longest leaf 10". Grown bright, intermediate to warm temps.
