AFFINITIES. 



This seems a hybrid in which E. rostrata appears to be concerned. What the 

 other parent is. if it.be a hybrid, is less clear. It appears to be E. ovata, which is common 

 in the district. 



1. With E. rostra ta Schlecht. 



The timber of the assumed hybrid may be described as resembling quickly- 

 grown rostrata, that is to say it is a little paler and a little more fissile than that of 

 normal rostrata. Comparison of the figures of E. rostrata as shown in Plates 136 and 137 

 of Part XXXIII, shows that there is considerable similarity in the mature leaves and 

 buds, and occasionally in the fruits, which are, however, larger in the hybrid. A wider 

 divergence is, however, seen in the juvenile foliage, which in E. rostrata is always thin 

 and glaucous, never puckered, rarely broad, and never, unless malformed, nearly 

 ovate. 



2. With E. ovata Labill. 



See Plates 113 and 114, Part XXVII, but particularly 2d of the latter plate, 

 which depicts the fruits of var. grandiflora, obtained from the Mount Gambier district 

 of South Australia. The timber of E. ovata is paler, and the resemblances in other 

 characters less close to the hybrid than is E. rostrata. 



3. With E. rudis Endl. 



For this species see Plates 138, 139, Part XXXIII. This is a Western Australian 

 species, with inferior, pale timber. The fruits of this species and of the hybrid are 

 sometimes not unlike ; the resemblance in the case of the buds is less close. The affinity 

 with E. rostrata is far closer.
