INTRODUCTIOX. 
Ihis paper contains descriptions of fifty new species of plants collected 
during recent years. It rei^resents a portion of the unpublished species which 
w^ere discovered during the work of the reorganisation of the State 
Herbarium, Perth, and is only a part of the total material aAvaiting descrip- 
tion. Since the publication of Conlrihiitiones X, six species 'were described 
at Kew in Hooker’s leones Plantarum tt 3378-3384, 1939. 
The material described in this paper consists in the main of selections 
from the collections of Dr. W. E. Blackall, and of specimens which we con- 
jointly collected during a tour undertaken in 1931, which covered a large 
tract of country in South-AVestern Australia. In addition there are a few 
species collected in the North- Almost between the Gascoyne and Fortescue Rivers 
in 1932 when I accompanied the Minister for Lands and Agriculture on an 
investigational tour during August of that year. 
Alore recently, whilst engaged on critical comparative studies in the 
Ilerbaiium of the Royal Botanic Gardens, Kew, and the Berlin Herbarium, 
further new species Avere brought to light, and some changes in nomenclature 
have been necessitated. Only a few of these have been incorporated in this 
paper; others will follow in the next Contribution. The collections of Mr. 
G. E. Brockway, District Forests Officer at Kalgoorlie have resulted in the 
discovery of some new species of Eucalyptus, and the recording of a hitherto 
little known s])ecies Avhich has been fully described. 
In jiresenting this paiier for publication, I desire to thank in the first 
place, Sir Arthur Hill, Director of the Roj^al Botanic Gardens, Kew, wiio 
extended to me every facility and courtesy in my studies there which occupied 
two years, and Avho so generously presented to the Stale Herbarium portions 
of type s]>ecimcns which are of inestimable Aalue. I am also indebted to 
Dr. L. Diels of the Berlin Herbarium, for the generous gift oi‘ numerous 
type fragments of specimens Avhieh he, in company with Dr. E. Pritzcl, 
collected in AA^'estern Australia in 1901 and 1902. 
Finally I Avish to express my thanks to Dr. AAR E. Blackall who has 
assisted mo by placing at my disposal the whole of his herbarium, and for 
the donation to the State Ilerbarinm of all the undescribed specimens which 
form the tyjie material of many of tlie species herein described.
