Ware working out at Kew the collection of botanical specimens which I 
gathered mainly on my travels in the North and the interior of Queensland in 
1909-1910, I obtained permission to study the unnamed Australian material in 
the Herbarium of the Royal Botanic Gardens at Kew. In the present paper 
I propose to give descriptions of new species and varieties found in those 
collections, and also to enumerate others which were already described, and 
especially such as are remarkable for their variability or were up to the 
present imperfectly known. 
The bulk of the material consisted of two very valuable and interesting 
collections of plants—one from North-Western Australia (between the 
Ashburton and De Gray Rivers) made by Dr. E. Clement, and the other 
from Western Australia by Capt. А. A. Dorrien-Smith, D.S.O. Dr. Clements 
collections prove that the flora of the region he explored is quite different in 
character from that of extra-tropical Western Australia, and much more 
similar to the plant-formations of Northern Australia and North-Eastern 
Queensland. Only a few of the characteristic species extend to extra- 
tropical Western Australia, which region is now fairly well known, more 
especially since Dr. L. Diels’s standard work, * Die Pflanzenwelt von West- 
Australien südlieh des Wendekreises " (Veget. der Erde, vii. Leipzig, 1906). 
Capt. A. А. Dorrien-Smith, however, found several new and very interesting 
species, some even in localities previously visited by botanists or botanical 
collectors, and there seems to be in this region of the world praetically no 
limit to the number of allied though distinct species especially in the sand- 
plains. 
For the full aecount of the description of the localities visited by Capt. A. 
A. Dorrien-Smith I refer to his own report in the Journal of the Royal 
Horticultural Society (vol. xxxvi. (1910) pp. 285-293: “A Botanizing 
Expedition to West Australia in the Spring (October, 1909) 7), which is 
accompanied by some views of the vegetation. 
In the present contribution I include only Monocotyledons, Ferns, and 
the Casuarina ; for practical reasons I thought it advisable to follow 
3entham’s * Flora Australiensis’ in the systematic arrangement. I hope 
later on te work out the numerous Dicotyledons brought by Dr. Clement
