Western localities-. — " Red Blackbutt," timber with straight grain, reddish 

 in colour, stem decidedly rougli, and black from the ground. Sunny Corner (J. L. 

 Boorman) ; " Blackbutt," rough, soft bark, clean ribbony tips, a good timber, which 

 is in demand for palings, leaves thick. Sunny Corner (No. 5, J. L. Boorman); 

 " Blackbutt," Bui-raga (R. H. Cambage) ; " Blackbutt," 15 miles southerly from 

 Oheron cross roads (R. H. Cambage); " Messmate," Tarana (A. Murphy) ; Jenolan 

 Caves, with rather thick foliage (W. ¥. Blakeley) ; Mount Wilson, Mount Irvine, 

 &c., all have wliite tops (Jesse Gregson and J.H.M.) ; the giant tree at Mount 

 Tomah is of this species ; diameter at ground, 17 ft. 6 in. ; 3 feet up, 16 feet 3 in. ; 

 height (estimated), 150 feet (J.H.M.) ; Hassan's Walls, Bowenfels (J.H.M.) ; at 

 the foot of Govett's Leap, Blackheath (R. H. Cambage). 



Nurllierii localiti/. — Yarrowitch, New England (J.LIM.) These specimens 

 absolutely match tlie type regiians, but the bark is i"0ugh. Most of the trees I 

 observed are small, though a few are 3 feet in diameter. Some of the umbels have 

 a double operculum. This New England record was made in 18'J8 {Proc. Aust. 

 Ass. Aitv. Science, vii, 539), and it remains to ascertain other northern localities, 

 and to connect them with the western ones. The following specimen is probably 

 one of such connecting localities : In general appearance resembles E. piiierita, but 

 seems of more sturdy and irregular growth ; generally is branchy and hollow, and 

 I should think of little value. On mountain tops, Upper Paterson and Allyn Rivers, 

 &c. (A. Rudd(;r, May, 1890). The fruits with valves not exsert, and leaves rather 

 coriaceous. 



AFFINITIES. 



1. Witli E. amygdalina, Labill. 



This has been incidentally referred to. The seedlings and juvenile leaves 

 (quite narrow in E. ainygdaUna) sharply separate the two species. Tbe mature 

 leaves also are usually broader. Turning to the fruits, those of E. amygdalina are 

 usually hemispherical, and those of E. regnans conoid. It is hoped that Plates 29 

 and 33 will make the principal differences between the two species clear, but there 

 is no doubt there are transit forms. 



2. E. vitellina, Naudin, and E. vitrea, R. T. Baker. 



See p. 189. Note also the specimens. Delegate River (W. Baiierien) and 

 Sunny Corner (No. 5, J. L. Boorman), placed under E. regnans.
