afterwards employed in the Sydney Botanical Gardens until his 

 death. 



In most of these expeditions valuable botanical collections 

 were made, and were afterwards dealt with by Mueller. 



About 1847, Mr. William Archer, of Tasmania, who had 

 collected an excellent herbarium, placed it at the disposal of Sir 

 Joseph Hooker, and contributed liberally to the cost of its pub- 

 lication. 



In 1848, Mr. James S. Roe, who had accompanied King in 

 his expeditions of 1818 and 1821, and was afterwards appointed 

 Surveyor-General of Western Australia, and took part in nearly 

 every exploring expedition sent forth in that colony, conducted 

 an expedition into the interior, extending over 1800 miles: he 

 was evidently an enthusiastic botanist, and we find his name 

 occurring frequently in the specific nomenclature of the plants of 

 Western Australia. 



In 1851, Mr. John Carne Bidwill, a surveyor, who in 1841 

 published an interesting book, " Rambles in New Zealand," and 

 was for a short time Curator of the Sydney Botanical Gardens, 

 afterwards went to Queensland, where he successfully used his 

 opportunities for doing good botanical service, and was the 

 discoverer of the Bunya Bunya, Araucaria Bidwilli. He formed 

 an excellent herbarium, which was transmitted after his death 

 to Sir William Hooker. He died the same year from the effects 

 of over-exertion when cutting his way through the forests of 

 Eastern Australia, between Wide Bay and Moreton Bay, where 

 he lost his way, and though rescued after eight days' starvation, 

 succumbed in acute pain to the injuries he had sustained. 



But the greatest of all contributors to Australian botanical 

 knowledge was undoubtedly the late Baron von Mueller, who, 

 after his arrival in Adelaide in 1847, removed to Melbourne, was 

 appointed Colonial Botanist to Victoria, and devoted many years 

 to uninterrupted exertion in travelling and collecting. 



In 1853 he visited Fuller's Range, May-day Hills, the Buffalo 

 Ranges, Mounts Aberdeen and Buller, and the Yarra Banges, 

 descending to the coast of Gippsland, and returning to Melbourne
