Tiny Purple Orchids

Although the flowers are tiny, this profuse mass of epiphytic orchids made a dazzling appearance this weekend! I remember this particular cascade "hitched" alongside a bird's nest fern that we bought some years back and mounted on a mango tree in the fern garden. Little did we know it will bloom this profusely! I don't even know what they are called, but I just wanted to post it right away even without properly identifying it.
