AFFINITIES. 



The history of the specimens is as follows : — 



' The trees from which herbarium specimens Nos. 2,735 and 2,736 were taken 

 were raised with plants of Eucalyptus saligna ([?] E. grandis (Hill) Maiden, " 'Flooded 

 Gum,' J.H.M.) from seeds collected from trees of this species growing in a shelter belt, 

 together with E. globulus, at the Kokstad Plantation (Transkei). It has not, however, 

 been possible to trace the origin of the shelter belt of trees." (J. J. Kotze.) Also 

 " Insizwa Plantation, Mount Ay lift district, Cape Province." 



1. With E. rebusta Sm. . . , >r , 



It seems to me that its closest affinity is with this species. Compare Part XXIII, 

 Plates 97 and 98. E. robusta is, however, only occasionally three-flowered; the juvenile 

 fobage does not closely resemble that of the hybrid, while the mature leaves have a 

 greater resemblance. There is a resemblance, though not a close one, in the buds, 

 but it is in the size and shape of the fruits that the resemblance is closest, but those of 

 E. robusta are not ribbed. The smoothness of the bark of the hybrid removes it from 

 E. robusta. 



2. With E. longifolia Link and Otto. 



Some of the remarks under E. robusta would apply to the present species. 

 E. longifolia has flowers in threes, and sometimes there is a tendency to ribbing of the 

 calyx-tube. 



3. With E. grandis (Hill) Maiden. 



In its general glaucousness and smoothness of its bark, the hybrid shows some 

 affinity to the above species. Compare Part XXIII, Plate 100. 



4. With E. globulus Labill. 



E. globulus has been mentioned ; it is growing near an E. globulus plantation, and 

 in its glaucousness and pale timber, and in the general appearance of its buds and fruits, 

 it presents a distant similarity to that species.
