except that it has a larger number of leaves than is seen in

Plants iised as Medicines and in the Arts. — The Malagasy 

 have from time immemorial been acquainted with numerous 

 roots, herbs, and trees which they believe to be efficacious in 

 medicine and surgery. These are largely connected with that 

 belief in charms which is the groundwork of their idola-

 aloe (called vdhana) is found plentifully on the bare summits 

 of the hills. The leaves are edged with red, and it bears a 

 tall spike of red and yellow flowers. 



In travelling through the skirts of the great forest on the 

 eastern coast, one passes continually through dense thickets 

 of a plant called longdzy. This is a species of cardamom 

 {Amomum cardamomum) ; the stem is a tall tapering rod, five 

 or six feet high, with a number of long simple leaves. The 

 fruit is a kind of scarlet pod, found near the base of the stem, 

 and contains a sweetish acid pulp of a silky white appearance ; 

 but if one of the small purplish black seeds is accidentally 

 crushed by the teeth, a most unpleasant burning sensation is
