E. pfychocarpa is a species Avith ribloed fruits, the fruits being large individually. 

 Such a species is also E. miniaia A. Cunn. ; see Plate 96, Part XXII. Those of 

 E. miniata are sessile, often more elongate and narrow, sometimes hardly constricted at 

 the orifice, but in other cases more constricted than in E. piychocarpa, and with the ribs 

 thicker. They differ also in the much smaller leaves of E. miniata and in the venation 

 of them, but I know of no closer affinity for E. ptychocarpa. 



2. With E. Ahergiana F.v.M. 



" Its affinity is with E. Ahergiana and E. miniata ; from the former it can be distinguished by its 

 longer leaves, with a still paler lower page, by its also still larger flowers, which are pro%*ided with usually 

 long stalklets (although Bentham describes the latter as occasionally also very short), and most particularly 

 by the fruit longitudinally traversed by about eight narrow, ridgps." (" Eucalyptographia," under 

 E. ptychocarpa.) 



For E. Ahergiana, see Plate 170, Part XLI, when it will be seen that the two 

 species are not very closely related. 



3. With E. Forrestiana Diels. 



This is a ribbed, large-fruited species, but the fruits are only four-ribbed, while 

 there are other differences (see Plate 95, Part XXII) which show that it is more removed 

 ■from E. ptychocarpa, than is E. miniata. 



4. With E. Planehoniana F.v.M. 



Although. E. Planehoniana has been referred to in Part IX, I have not figured it, 

 since Mueller had figured it in" Eucalyptogr-apliia," and I had nothing of importance 

 to add. I have, however, figured it in Plate 90, Part XXIV of my " Forest Flora of 

 New South Wales," to which I beg to refer my readers. It will be see that 

 E. PlancJioniana is a large-fruited species, Avith some ribbing of the buds and fruits, 

 more marked in my plate than in I\lueller's. E. Planehoniana is an Easte]-n Australian 

 tree, whose affinities are not close to those of E. ptychocarpa.
