EUCALYPTUS MACROCARPA. 



Youngiana of E. pyriformis the stalklets are almost wanting, though fruitstalks are always 

 developed. This is one of the largest-fruited of all Eucalypts, thus the specific name is well 

 chosen. 



The first notice of this remarkable species occurs in Sir William Hooker's Journal of Botany, 

 1840, p. 360, from a letter of Mr. James Drummond, who discovered the plant in the previous 

 year. It has claims for ornamental culture, especially when scenic effect is desired, as the flowers 

 are so large and handsome, while the ashy grey of the foliage contrasts remarkably with the 

 ordinary green of shrubberies. As this bush is only sparsely distributed in its own region, it is 

 to be feared, that in course of time, by the methodic " burning off," to which the " scrub-lands " 

 are subjected by the settlers, it will pass altogether out of natural existence like so many other 

 local plants of Australia, to make space for the upgrowth of pastoral vegetation. Hence the 

 desirability of giving this Eucalypt a permanent footing in horticulture abroad. While travelling 

 through regions of its growth, I found that this species most readily ignites. The accomplished 

 Miss North prepared, during her recent stay in West-Australia, among the oil-paintings illustra- 

 tive of indigenous vegetation, also a picture of this Eucalypt for the art-gallery, which she 

 generously provides for the large museum of the Royal Botanic Garden of Kew, under Sir 

 Joseph Hooker. 



Already in 1849, while illustrating this species, Sir Joseph Paxton observed, that this and 

 other Eucalypts " may be easily propagated by cuttings of the half-ripened wood, planted in sand 

 under a hand-glass." This process may readily be resorted to, when especially in conservatory- 

 culture any Eucalyptus should fail to mature seeds.
