Fruits. — Three fruits are available, picked ofi the ground and somewhat weather-worn. Cylin- 

 droid, slightly constricted in the middle, with some indistinct ribs, in very low relief below the constriotion, 

 .7 cm. long, and about -4 cm. broad at the orifice. Tips of the valves not appearing above the orifice. 



Habitat. — The village of Dundas, Western Australia, after which the species is named, is situated 

 15 miles south of Norseman, on the Esperance road, and was the centre of the early mining operations on 

 the Xorseman field. 



AFFINITIES. 



I have not obtained additional material, although I have tried, at intervals 

 extending over a number of years. I cannot identify it with any described species, 

 and I think it should be given a name. 



A species cannot be satisfactorily defined unless its affinities are indicated, and 

 if the material and data {e.g., concerning the timber) fall short of completeness, the 

 suggestions as to affinities must of necessity be tentative. 



The present is one of the narrow hook-leaved species of which there are not a 

 few more or less uncinate, e.g., E. uncinata, Turcz. (in which the hooks were thought 

 to be characteristic of the species); E. oleosa F.v.M. (especially some of its narrow- 

 leaved forms); E. angustissima, F.v.M.; E. calycogona, Turcz. var. gracilis, Maiden; 

 E. cneorifolia, DC. ; E. Moorei, Maiden and Cambage. 



1. With E. Clelandi Maiden. 



This is another goldfields " Blackbutt," and it is depicted at Part XVI of my 

 ' Critical Revision." The species are quite distinct, E. Clelandi being glaucous, with 

 dull foliage, ribbed buds (particularly the opercula). The fruits of E. Clelandi are 

 nearer than the buds to those of E. Dundasi, but the former are not constricted in the 

 middle and otherwise differ somewhat in shape. The buds of E. Clelandi are immature, 

 and the immature anthers are, in that state, not dissimilar to the immature anthers of 

 E. Dundasi. 



2. With E. oleosa F.v.M. 



At Plate 66, fig. 2 of this work, a narrow-leaved form of this species is depicted, 

 which displays considerable superficial resemblance to the present form. It is an 

 aberrant form of E. oleosa, but one hesitates to give it a varietal name. It differs from 

 E. Dundasi in the anthers and also in the buds and fruits.
