Dancing dolls - An apt name for this flower

Saw these flowers growing in one of the coffee planters house. The lady who planted this plant told me that it was known as "Dancing dolls". A very apt name,for these flowers look like small dancing toy dolls [ the type you would find in local shops in villages]. They grow in bunches and hang down from the tip of the plants. They resemble small bells to me, and they actually dance in the wind!
