EUCALYPTUS MELLIODOEA. 



farnisli about 2 lbs. 12 ozs. of pure potash, but mucli more crude pearlash, accordiDg to an 

 experiment instituted in my laboratory. 



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

 longitudinally conjoint ; tie 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 in that of 

 many other Eucalypts, contrasting well by its delicate cell-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. melliodora differs as a species from E. Leucoxylon irrespective of the differences of the 

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

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

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

 partially paniculate disposition, often in a less pointed lid and in the fruit generally more 

 contracted at the orifice. 



The leaves of seedlings are scattered, often oval or oblong and slightly stalked, while in 

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

 discriminations need to be still further followed up. 



Explanation of Analytic Details. — 1, summit of calyx, lid detached ; 2, longitudinal section of unexpanded 

 flower ; 3, some sterile and fertile stamens in situ ; 4 and 5, front- and back-view of anther ; 6, style and stigma ; 

 7 and 8, longitudinal and transverse section of fruit ; 9, seeds ; 10, portion of a leaf; all variously magnified.
