H.Columnaris is endemics to the mascareigne islands. Rare, spotted in some reserves in Mauritius and in Reunion island. It is a protected species and is called "Mahot Rempart" . The flowers are completely yellow with a thick and long pistil . Leaf has yellow veins , which gives it green-yellow look and is rather fuzzy (slighlty sandpapery) . The bark is brown at base and dark green on the top part. It can now be found in nurseries specialised in endemics plants in Mauritius.
