those of the Pomegranate have a fleshy coat, and those of Ejnlobium are furnished 

 with hairs. The Myrtales are distributed over all quarters of the globe. The 

 Chamselauceae and Leptospermacese are natives of Australia and the islands of 

 the Pacific Ocean. Several species of this family help to form Australian bush, 

 whilst others, especially species of the genus Eucalyptus, constitute entire forests 

 (see Plate XVI.). The Lecythidaceae grow chiefly in South America. The Myrtacese 

 are most abundant in America, and occur also in Asia and Africa. Europe only 

 possesses one species, Myrtus com/munis, which belongs to the Mediterranean Flora. 

 The Fuchsias are indigenous to Central and South America. The Epilobiums and

 The number of species ascertained to exist at the present day is about 2500.
