CALABAR OF ECONOMIC PLANTS. 77 



a large tree of the Star Apple family (Sapotacese). The fruit is 

 about 3 inches long, similar to the Sappodilla Plum, but the

Cajeput Oil {Melaleuca minor), a moderate-sized tree of the 

 Myrtle family (Myrtaceae), native of the islands of the Indian 

 Archipelago, and Eastern and ISTorthern Australia. It is called 

 the White Tree on account of the colour of its bark, which is 

 white and in layers, like thin paper. It is used by the natives 

 for many domestic purposes. The leaves of the tree, which are 

 smooth and myrtle-like, by fermentation and distillation yield a 

 green oil known as Cajeput. It is highly valued in medicine 

 as a carminative, stimulant, sudorific, and antispasmodic ; also 

 externally in chronic rheumatism, and is much used as a cure for 

 cholera. A species of Melaleuca, with white papery bark 

 (probably M. minor), is described by Drummond as growing 

 in West Australia.

 at the apex, and bearing short racemes of sweet-scented flowers. 

 The fruit is drupe-like, containing a single seed, which yields an 

 oil fit for lamps. In Brazil the wood is called Santa Maria

 has since been discarded.

 climber of the Bean family (Leguminosse), having a woody 

 stem 2 inches in diameter, attaining a great length. The pods 

 are about 6 or 7 inches long, and contain several seeds of a 

 kidney shape, about an inch in length, of a dark chocolate brown 

 colour, approaching black. They are highly poisonous. The 

 plant is a native of Old Calabar, and is there used by the natives 

 as an ordeal, and is generally known as the Ordeal Bean of Old 

 Calabar. In 1864 a quantity of these beans was imported into
