This is a handsome and veiy distinct plant, with more the habit of growth of the European species than of the 

 larger and more leafy H. redolens or antarctica. It is very abundant in some parts of the islands now under consi- 

 deration, always growing in exposed situations, where its graceful habit and nodding panicles are a great ornament to 

 the dreary regions it inhabits.
