From the Family Rubiaceae which includes the common Ixora, this plant from Brazil has a common name Needle Flower Tree. It is known that such deep throated flowers are often pollinated by moths, or hawkmoths in this case.
It is such a delight to see and plant this rare plant in a garden worthy of its beauty. A link on this plant is attached here:
