 (Walp. Repert. ii. 924; Suppl. i., 1845.) 



The type is in the Vienna herbarium (Herb. Musei Caesarei 

 Palatini Vindobonensis). It is in plump bud and expanded 

 flower. It bears a label, in Schauer's handwriting, " Eucalyptus 

 Baueriana, Schauer, in Walp. Repert.," and also the words " E. 

 Baueriana, Schauer," written over a label "Eucalyptus rhombi- 

 folia, Tausch." 



Access to the type has enabled me to settle the identity of 

 Schauer's plant. Collected by Ferdinand Bauer, it was doubtless 

 obtained in the Port Jackson district; and it is the Lignum-vitae 

 or Poplar-leaved Box which was always looked upon by Mueller 

 as a form of E. jyolyantheinos, Schauer, and w^iich, later on, was, 

 as will be indicated presently, recognised as a distinct species. 



Bentham (B.Fl. iii. 214, under E. polyanlhemos) says: — "The 

 tropical specimens to which, from the character given, belongs E, 

 Baueriana^ Schau , in Walp. Pvep. ii. 924, have generally smaller 

 flowers and fruits than the southern ones, but do not otherwise 

 diff-er." 



I am not clear as to the allusion to " tropical specimens." 

 There is no evidence that Bauer obtained the specimens, described 

 by Schauer, in the tropics, or was, in fact, in troj^ical Australia
