AFFINITIES. 



Mr. Andrews has observed that E. diptera does not appear to have any very 

 close ally, and while it certainly has allies, we cannot say what they are at present. 

 The figure on Plate 71 has been prepared from the whole of the material at his 

 disposal. There are no juvenile leaves, no opercula, and the fruit is not perfectly 

 ripe. But it can be seen that it is a very distinct species. 



1. With E. incrassata, Labill., var. conglobata. 



Buds in this variety are sometimes winged ; we know nothing of the opercula 

 of E. diptera. Tlie fruit of U. diptera is very different, and the leaves are wider. 



2. E. obcordata, Turcz., var. nutans, has winged buds and fruits, but it has also 

 strap-shaped peduncles, and many other differences. 



3. With E. Oldfieldii, F.v.M. 



The nearly sessile-flowered twig of E. Oldfieldii var., figured on the right 

 hand of the E. Oldfieldii plate of the " Encalyptographia," bears a superficial 

 resemblance to E. diptera so far as we know it, but only superficial. 



4. With E. Griff ithsii, Maiden. 



This also is a winged species, so far as the bud is concerned, but reference to 

 Plate 71 shows that there is no further resemblance.
