AFFINITIES. 



1. With E. incrassata, Labill. 



Mr. Luehmann drew attention to this. The coiTugation in the organs of 

 E. incrassata can be seen in Plate 14. After the first proofs of Plate 70 had been 

 printed off I found a few immature stamens in my Southern Cross specimens and 

 figured them at 7c. The anthers are what I know as "incrassata " anthers. 



2. With E. Le Souefii, Maiden. (See Plate 69.) 



In this case the operculum is very different, as has been pointed out {ante 

 p. 188). Here are two forms, and there are others, which belong to the E. incrassata 

 group, and different botanists may hold different opinions as to whether we should 

 constitute a wider E. incrassata, with many varieties. Until Westei*n Australia (not 

 to mention other States) is very much better explored botanically, it seems desirable 

 •to give specific names to some of these forms. 



3. With E. paehyphijlla, P.v.M. 



Mr. Luehmann drew attention to this, but he did not give the name of the 

 author. It is not, however, E. pachyphylla, P.v.M., p. 101, Part IV, nor E. paehy- 

 phijlla, A. Cunn , p. 103 of the same Part, both of which are forms of E. incrassata. 



It is doubtless another E. pachyphylla, P.v.M., viz., that which is figured in 

 the Eacalyptographia, and which is thought by some to be a form of E. pyriformis, 

 Turcz. It has been figured at (ia and 6b of Plate 75, which will be published in 

 Part XVII of this work. Fruits, buds and anthers are very different ; the two species 

 have raised ribs on buds and fruits ; this presents their greatest similarity. 



4. With E. goniantha, Turcz. 



Diels and Pritzel (Engler's Jahrb., XXXV (1905), p. 443) drew attention to the 

 strong affiaity between these two species. The buds and flowers of E. goniantha are 

 alone known. As will be seen from fig. la, Plate 18, Part IV, the opercula and the 

 buds generally are very different.
