Native of Australia (Victoria) and Tasmania; introduced by Sir Joseph Banks to Kew in 1780. There was once a very healthy plant at Lanarth in Cornwall, which reached a height of 20 ft and as much in spread, and bloomed in April and May. It is very beautiful every spring in the Australian House at Kew and is distinct among the acacias here described by the short prickly 'leaves' being arranged in whorls, but there are several other species in the genus that are similar in that respect.
