AUSTRALIAN lichenology begins with this century. 
In 1791 M. Labillardiere accompanied Amiral d’Entrecasteaux 
in his expedition in search of La Pérouse, and, on returning to 
France, he published the results of his collection in his “ Novee 
Hollandize Plantarum Specimen,” 1804. He gives description 
and drawings of one lichen from Cape Van Diemen, New 
Holland, which he named 4eomyces reteporus. Acharius calls it 
Cenomyce retipora, Syn. Meth., 1814. Acharius mentions only 
another lichen from New Holland, Col/ema tremelloides, vay. 
pichneum, sent to him by Thunberg. 
In 1802 Mr. Robert Brown accompanied Captain Flinders in 
his investigation of the coasts of New Holland; and of the 
lichens collected by him he gives a list of 58 species common 
to Australia and Europe, in Appendix 3 to “ Flinders’ Voyage 
to Terra Australis,” 1814. Brown’s collection lay in the British 
Museum for nearly 80 years, until Rev. Mr. Crombie revised 
it, and published the names of 73 lichens, inclusive of 12 new 
species described by him.—/ourn. Lin. Soc., Lond., 1880. 
In 1817 M. Gaudichaud accompanied Amiral Freycinet in his 
expedition to the South Seas, and on returning to France 
published the results of his collection in the botanical part of 
Freycinet’s “ Voyage Autour du Monde.” The lichens were 
determined by Persoon, and 4 of them were gathered in 
Australia. 
In 1827 Sprengel’s “Systema Vegetarum” mentions only 2 
Australian lichens. 
In 1838 Herr Ludovic Preiss, visiting Swan River, met there 
a botanical resident, James Drummond, who took Preiss through 
the neighbouring country. When he returned to Europe he
