"White-topped Messmate," Kangaloon. "Grows on rich soil; inferior 

 timber. Carefully distinguished locally between " Black-topped Messmate," a 

 good timber which grows on poor soil" (J. Bruce). I can see no botanical difference 

 in the two sets of specimens, and Mr. Brace's observation is an illustration of what 

 has been often remarked " Good timber, poor soil," and vice versa. 



" White Ash." Hoskinstown (W. Daniel) ; Box Point to Barber's Creek, 

 also Nye's Hill, Wingello (J. L. Boorman and J.H.M.) ; Bowral to Bullio (U. II. 

 Cambage and J.H.M.) ; " Stringybark," Mittagong (W. W. Froggatt) ; Berrima 

 (J. L. Boorman and J.H.M.) ; Hill Top (J.H.M.) ; Appin (J.H.M.). 



Western Localities. — Has on the Blue Mountains a range very similar to 

 that of E. piperita, and is confined to the more barren parts of the mountains. 



Mt. Wilson (Jesse Gregson) ; Jenolan Caves and Black Range generally 

 (W. Blakely). 



I have seen specimens from the Mudgee district (Forester C. Marriott), but 

 there are none in this Herbarium. 



I have seen no E. Sieberiana specimens north of the above localities, but 

 certainly expect to hear of such in the mountain ranges going north from the places 

 named. 



AFFINITIES. 



1. With E. virgata, Sieb. 



This has been dealt with under E. virgata, in Part IX. 



2. With E. Luehmanniana, F.v.M., var. altior, Deane and Maiden. 



Dealt with under E. Luehmanniana in Part IX. E. Sieberiana has a rugged 

 black bark ; the variety of Luehmanniana is a Ribbony Gum. Sometimes the 

 unripe fruit and herbarium specimens generally very strongly resemble those of 

 E. Sieberiana, but I think the drawings in the last and present Parts will put 

 botanists on their guard. 



3. With E. Consideniana, P.v.M. 



Will be dealt with under E. Consideniana. 



4. With E. hcemastoma, Sm. 



Mueller, in "Eucalyptographia," speaking of E. Sieberiana and E. h(Bmastoma, 

 states that " the stem bark of the former is far more ridged than that of the latter, 

 the veins of the leaves of E. Sieberiana are less spreading and less prominent, while 

 the fruit is usually longer, more exactly semiovate and never verging towards an
