barks. The superficial appearance of the barks of the trees 

 does not command a ready assent to Von Mueller's cortical 

 arrangement of them. The bark of Eucalyptus robusta or 

 Eucalyptus corymbosa is, in looks, not at all like that of 

 Eucalyptus cornuta, but these are classed together in the 

 "Rhytiphloiae. Nor is the bark of Eucalyptus rostrata out- 

 wardly even suggestive of that of Eucalyptus globulus, 

 though these two stand cortically together in Leiophloiae. 

 Prof. Maiden writes me from Sydney that he considers 

 the ' cortical classification the best for field use.
