under the title of " Plants Preissianae." A small West Austra- 

 lian gum-tree, KiicKli/jitu.s Preis.siami, Sciiauer., is named after 

 him. 



1839. — James Drummond, one of the most zealous of 

 Australian botanic collectors, began work in 1839 and continued 

 for sixteen years, and to his labours we owe most of our know- 

 ledge of the West Australian tiora. His first collection was 

 mostly determined and published by Dr. Lindley ; some, however, 

 were published by the Kussian botanist, P. K. N. Turczaninow, 

 in the " Bulletin de la Societe Imperiale des Naturalistes de 

 Moscou." Kneah/jdHs Drunniiomlii, Benth., is named in honor 

 of this excellent collector, but in Queensland his name is better 

 known as bemg attached to the little " caustic creeper " 

 Eujilidrhid nnaniiiondii, Boiss. About this time, also, Capt. 

 Mangles collected many species of West Australian plants, 

 several of which have his name attached to them — the one best 

 known in garden culture, is probably Dr. Lindley's Wmdanthe 

 2[iiniilisu, or, as it is now known, Helipteruin Mdnijlfsn, F.v.M. 

 During the year 1839 also, Capt. D'Urville visited Sydney and 

 Tasmania, and the medical officers of his expedition, MM. 

 Hombron and Jacquinot, managed to secure a few herbarium 

 specimens. 



1839. — The United States Exploring Expedition under Com- 

 modore Wilkes also visited Sydney this year, and the party made 

 large collections of the plants in the neighbourhood of Sydney ; 

 these specimens were determined and published in Professor Asa 

 Gray's " Botany of the United States Exploring Expedition." 

 The botanist of this voyage was W. D. Brackenridge. and a 

 genus of Ochnacefe, Dnickmridncd, Gray, was named in his 

 honour. 



In the same year, .John l^ailey, the Colonial ]]otanist of the 

 then young colony of South Australia, arrived at Adelaide, and 

 made collections of plants about the town and district. These 

 were principally sent to his old friends, the Messrs. Loddiges, of 

 London, in a live state, or as seeds. The native Hora of the 

 Adelaide district is probably the least interesting of the Aus- 

 tralian colonies ; it cannot be wondered at, therefore, that we 

 find his energy directed more towards the introduction of useful
