In Trans. Roy. Soc. S. Austr. 1903 (pp. 240-252) I published a 

 paper on E. odorata, Behr. Examination of some tj^pe-specimens 

 which have come into my hands since 1902 (the year the above 

 paper was written); recognition of the fact that under ^. odorata 

 two series of plants, — those with broadish and those with narrow 

 suckers — have for many years been included; and acceptance of 

 the fact of hybridisation in the genus, have all contributed to 

 modification of some of the views expressed in that paper. 



E. odorata is usually a tree, the " Peppermint " of South Aus- 

 tralia. It may be also a Mallee, The narrow-suckered forms 

 may be Mallees, or less commonly trees. The hybrids are usually 

 trees. 



Let me arrange certain trees in the following ways : — 



A. — Red timbers. 



1. E. odorata, Behr. 



2. The Ironbark Boxes. 



3. E. cajuputea, F.v.M. 



4. E. acacioides, A. Cunn. 

 B. — Pale or brown timbers.

2. E. hemiphloia, F.v.M., var. 7nicrocarpa, Maiden. 

 A^. — Plants with broadish suckers. 



a. E. odorata, Behr (typica), Syn. E. calcicultrix, F.v.M. 



b. E. hemijMoia, F.v.M., var. microcarpa, Maiden. 



c. The Ironbark Boxes. 



B^. — Plants wIth narrow suckers. 



a. E. cajuputea, F.v.M., Syn. E. polyhractea, R. T. Baker. 



b. E. acacioides, A. Cunn., Syn. E. viridis, R. T. Baker;
