EirCALTPTtrS MELLIODORA. 



fiimisli about 2 lbs. 12 ozs. of pure potash, but nmcli more crude pearlasb, according to an 

 experiment instituted in my laboratory. 



The medullary rays are very distinct, occurring in four or less rows of elongated cells 

 longitudinally conjoint ; the vascular tubes show a diameter of only about 0-09 mm. or often less 

 width, with comparatively thick and copiously dotted walls. Dr. Josef Moeller first observed, 

 that the Parenchyma is more extensively developed in the wood of this species than ia that of 

 many other Eucalypts, contrasting well by its delicate ceU-walls and irregular contour with the 

 less wide and roundish transverse section of the wood-fibres, the diameter of the latter being only 

 about 0'012 mm. 



E. meUiodora differs as a species from E. Leucoxylon irrespective of the differences of the 

 wood, in the less deeply fiirrowed persistent portion of the bark and ia the yellowish tinge of its 

 inner layers, in usually smaller leaves, flowers and firuits, shorter flowerstalks and mostly also 

 less elongated stalklets, farther in more numerous flowers of the umbels with a tendency to a 

 partially paniculate disposition, often ia a less poiated lid and ia the fimit generally more 

 contracted at the orifice. 



The leaves of seedliags are scattered, often oval or oblong and slightly stalked, while ia 

 E. Leucoxylon they are as a rule opposite, sessile and broader towards the base ; but these 

 discriminations need to be stiU farther followed up.
