AFFINITIES. 



1 and 2. With E. tereticornis Sm. and E. rostrata Schlecht. 



" This is probably the same as E. rostrata, notwithstanding the differences 

 described in the bark." (B. Fl. iii, 241 ). 



E. exserta has for many years been erroneously included- under both E. rostrata 

 and E. tereticornis. Mueller in Eucalyptographia, under E. rostrata, says, " In respect 

 to the fruit E. exserta approaches closer to E. tereticornis than to E. rostrata, differing 

 from both in the persistency of its outside wrinkled and rough, inside somewhat fibrous 

 bark; both E. tereticornis and E. exserta have the stalklets often thicker and shorter 

 than E. rostrata." 



But a more obvious difference between this species and tereticornis and rostrata 

 lies in the brown (not red) timber of exserta. 



As regards E. tereticornis, Plate 128 (Part XXXI) may be referred to, and, as 

 regards E. rostrata, Plates 136 and 137 (Part XXXIII). The broad juvenile leaves of 

 both species (particularly the former) sharply accentuate them from E. exserta, and so 

 do the usually narrower mature leaves of the last. 



In the forest, the rough bark of E. exserta is a distinct character. 



While normally the buds of E. tereticornis and E. rostrata are different enough 

 from those of E. exserta, certain exceptional buds suggest caution. The fruits of 

 E. tereticornis more closely resemble those of E. exserta than do those of E. rostrata, the 

 latter being more hemispherical and with a sharper, flatter rim. In E. exserta, as 

 compared with E. tereticornis, the whole fruit is narrower, the rim is broader, and the 

 valves much more exsert. 



3. With E. rudis Endl. 



' There may be also some confusion in Oldfield's specimens (from the Murchison 

 River, Western Australia ), the larger-flowered ones may belong to E. rudis, which differs 

 in its large flowers, shorter pedicels, and in the much larger fruit with a flat rim." 

 (B. Fl. iii, 241). 



E. rudis is a Gum (not a Peppermint), having a smooth bark with a more or less 

 rough butt./ It has broad juvenile leaves, and the fruit tends to be hemispherical, and 

 is often urceolate. 



Oldfield's Murchison specimens that I have seen I would attribute to a large 

 fruiting form of E. rostrata, tending to E. rudis. 



4. With E. Morrisi R. T. Baker.
