This flower stalk was on a large tree growing along the driveway of a hotel in the cloud forest. I didn't see any with these buds open, so I don't know if they even do open. The color of these range from deep purple to lavender. The "flower" section was rather large - perhaps about 7-10" long
Looks like Medinilla sp. After the flowers you get these beautiful berries. medinilla - Google Search medinilla berries - Google Search:
