set of specimens. Upon arriving in the Daintree area Webb and Tracey stopped at a small watercourse called Oliver Creek, a short distance south of Cape Tribulation, where they were soon able to locate a number of the trees in full flower amidst the riparian forest. They collected samples of the plant including a piece of bark as well as samples from other trees with which they were unfamiliar. These included a number of species which had not previously been recorded in Australia such as Ryparosa javanica and Gardenia actinocarpa as well the then undescribed Lepiderema hirsuta. Upon analysis of the bark sample that Webb and Tracey had collected at Oliver Creek, chemists were able to isolate an alkaloid called Calycanthine which initially suggested that Stan Blake was correct in his assumptions about the identity of the plant. Upon closer inspection of the fruit and the flower specimens together, along with details of the size of the tree, it soon became apparent to Blake that the poisonous fruit did not belong to a Calycanthus despite it being a part of the Calycanthaceae family which represents a very primitive line of angiosperms. Blake determined that the specimen was so different from the rest of the Calycanthaceae family that a new genus called Idiospermum was erected with Idiospermum australiense as the sole species.
