Afflinities. 



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 figure of such material as is 

 available will be given in my "Critical Revision" in due 

 course. 



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. calyeogona, Turcz. var. gracilis, Maiden ; E. cnerifolia, 

 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 con- 

 stricted in the middle and otherwise differ somewhat in 

 shape. The buds of E. Clelandi are immature, and the im- 

 mature 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
