 Cattleyanum of Brazil. The Malay-Apple and Eose- 

 Apple are the fruits of Ikigienia malaeeends and E.

 of E. pimenta of the West Indies, gathered and dried 

 before ripening, is the Pimento, or Allspice, in common 

 use. E. aromatioa is the Clove-tree of the Moluccas, 

 whose flower-buds are collected and dried, and constitute 

 the cloves of commerce. The Brazil-nuts are the rough

 Mia excelsa, a Tropical American tree one hundred tO' one 

 hundred and fifty feet high. The hard-mottled wood of 

 Myrtus communis, the Myrtle-tree of Western Asia, is much 

 used in turnery. Various species of the vast genus JEmco- 

 lyptus, of Australia and Tasmania, are large and important 

 timber trees; the wood is tough and durable, and much 

 used in structures exposed to sea-water. The Blue-Gum 

 (£. ghbulua) is now being planted in California^ From
