E. tereticornisj Sm., non var. lati/olia, Benth., B.Fl. iii. 242. 

 Suggested that it might perhaps be a form of var. lati/olia, Benth., 

 by Maiden in Bull. Herb. Boissier, 1902, p. 571; Forest Flora, 

 N.S. Wales, Part xi. p. 7. 



I am satisfied that this " Swamp Gum " or " Broad-leaf Blue 

 Gum " is a distinct species. In its commonest form it is a small 

 or medium-sized tree, inclined to a crooked stem and scrambling 

 branches, with long, narrow, horned or tapering opercula (the 

 arrangement of the buds is usually stellate) and small fruit, the 

 valves well exserted and numerous in the head. It is common 

 in damp situations in Western New South Wales and Queensland, 

 but may occur in dry rocky places. The juvenile foliage is 

 always broad and often with the venation very marked. The 

 mature foliage may be broad or lanceolate; its texture varies, 

 but it is usually coriaceous. Its transit to normal tereticornis 

 appears (in one direction) to be through E. angulosa, Naudin, a 

 form I cannot recognise as of specific value. 



I hope to make some observations concerning E. cimicina, R.Br.; 

 and E. tereticornis, Sm., var. lati/olia, Benth., in my next paper. 



22. E. TERETICORNIS, Sm., var. dealbata, Deane and Maiden. 



In these Proceedings for 1901 (p. 204) Mr. R. H. Cambage 

 has drawn attention to the occurrence of this variety in Mallee- 

 like form at Wirlong near Nymagee. Mr. J. L. Boorman has 

 recently found the same variety in Mallee-form at Gungal near 

 Merriwa. He has two forms which in the National Herbarium 

 are called A and B respectively. A is not so robust as B, and 

 with rather narrower leaves. The fruits of B are larger and 

 more urceolate than those of A.

It is sometimes difficult to discriminate between this species 

 and E. tereticornis, Sm. The seedling leaves of the former species 

 are narrow, while those of the latter are much broader.
