AFFINITIES. 



1. With E. macrocarpa, Hook. 



E. pyriformis is closely akin to E. macrocarpa, but any whitish bloom on it is confined to the calyces 

 and their stalks, the leaves are always narrower and gradually attenuated at the base, only exceptionally 

 opposite and even then obviously stalked, the flowers stand seldom singly, and are never absolutely sessile, 

 the calyx has not an even surface, the upper portion of the fruit from the edge of the calyx-tube to the 

 rim of the disc is more elevated, and at the summit more contracted, reaching beyond the base of the 

 valves. (" Eucalyptographia," under E. pyriformis.') 



I will institute a comparison between the two species when I figure 

 E. macrocarpa (in Part XVIII). 



The anther of E. pyriformis is remarkable, and may be described as very 

 irregular in shape and peculiarly curved. Further, they are not strictly uniform 

 amongst themselves. There is a gland in front, near the top, and the dehiscence is 

 extensive, being fully from top to bottom. The attachment of the filament is nearly 

 at the base. The drawings of the anthers of E. pyriformis have been made from dry 

 specimens, and the curvature is partly a matter of shrinkage. 



The anthers of all the varieties of E. pyriformis are similar, and have flat, 

 ribbon-like filaments in addition. The anthers of E. macrocarpa are similar. Those 

 of E. orbifolia are closely allied, but the material available is too scanty to be 

 satisfactory. The anthers of E. Oldjieldii are allied. 



2. With E. Preissiana, Schauer. 



This is a large- fruited species with yellow filaments, hut the fruit is smaller 

 and of quite a different shape to that of E. pyriformis. The leaves and anthers are 

 both different. E. Preissiana will be dealt with in Part XVIII. 



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



Bentham, speaking of E. pacliyphylla, F.v.M., says : — 



The specimens are insufficient to determine the affinities of this species. In some respects they 

 resemble K. cosmophylla and its allies; but the fruit, the seeds and, perhaps, the inflorescence are 

 different, (B.F1. iii, l':V7.) 



It will be more convenient to deal with this matter when I figure E. cosmophylla. 



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



I have a note on E. pyriformis, var. minor (E. pacliyphylla, F.v.M.), and this 

 species above, page 225.
