Vili CONCLUDING PREFACE. 
It is now my pleasing duty gratefully to acknowledge the handsome | 
manner in which Baron von Mueller has fulfilled his promise of afford- | 
ing me every assistance in the prosecution of the arduous task I had | 
undertaken. He has regularly transmitted to me, arranged for each 
volume, the vast stores of Australian specimens collected by his own 
exertions, as wellas by the able collectors he has employed and the 
numerous residents and other correspondents whom he had inspired | 
with a love for the science. I have been able also to take full ad- 
vantage of the results of his own previous study of the specimens, a8 
published in his Fragmenta, the sheets of which he has regularly for- 
warded to me as printed off. The specimens, after having been worked 
up, have been successively returned, and the numerous consignments 
have reached Melbourne without a single loss, the last of the Graminex 
and the ferns alone being still on their way home. 
To the various other sources enumerated in the Preface to the first 
volume, as having supplied me with materials for this work, the most 
important additions I have to record are the valuable collections made 
by M. Schultz, at Port Darwin, and by some of the recent explorers — 
of Central Australia, of which Dr. Schomburgk, the active Director 
of the Botanical Gardens of Adelaide, has transmitted to me almost 
complete sets, and a number of interesting specimens, chiefly from 
the northern districts of New South Wales and from Lord Howe’s 
Island, sent to me by Dr. Moore, Director of the Sydney Botanic 
rden. 
December, 1877.
