10 ANNIVERSARY ADDRESS, 
that out of upwards of 400 species which it contains there is 
single orchid amongst them. The Baron’s report of the forest 
sources of Western Australia, of which there is a copy in the li 
of this Society, is a valuable contribution to our knowledge of 
vegetable economical resourcesof that Colony, and as a labourotk 
that gentleman has published, at his own expense, an index to 
first edition of the “Species Plantarum” of Linnezus. This 
was published in 1753, and is exceedingly rare, and the inde 
be the more valuable as it is from the second edition of that 
lished in 1762 and 1763 that quotations are made in the 
recent descriptive works on botany. I would also refer to 
botanical researches of Mr. Bailey, F.L.S., of Brisbane, who 
done much, under considerable difficulties, in investigating 
botanical resources of Queensland. His works on the grasses 
ferns of that colony are most creditable and highly interesting | 
ductions ; and in an address recently delivered by that distin- . 
guished geologist and naturalist, the Rev. J. E. Tenison-W' 
F.G.S., F.L.S., we learn that Mr. Bailey is now engaged in 
ing up the lower order of the Australian flora. I must also aeV 
to and award my tribute of praise to the ability and research ¢ 
played by Mr. R. D. Fitzgerald, our Deputy Surveyor Gen 
the publication of his work on Australian orchids. When 
considered tat this gentleman, during the time unoccupied by ! 
public duties, has furnished with his own hand carefully * 
accurately drawn figures of the complete plant, and sections 
parts of the flower, and has given an excellent diagnosis of all 
species which he has so beautifully illustrated, some faint 
may be formed of the industry required in carrying out 5° far t 
very valuable work. 
While making this brief and very imperfect referene?” 
what has been and is being accomplished in botanical p" 
_ I may be pardoned in drawing attention to the very 
necessity which now and has long existed of ascertaining thes 
and economic value of the Australian flora. The knowledge 
we possess of the properties of the greater number of the p 
the Colony is most imperfect. How little, for instance, is ©
