Passerina-likc Tamarisk. Shrub. 



Cult. Tamarix is a genus of very pretty and delicate shrubs. 

 The hardy species are fit ornaments for decorating shrubberies ; 

 they will grow well in any soil or situation, and cuttings planted 

 out in the open ground in autumn or early in spring strike root 

 readily. The stove and greenhouse kinds succeed well in a 

 mixture of loam and peat; and cuttings of them root freely in 

 sand under a hand-glass, those of the former in heat.

 Tamarisk, especially this species, is sometimes used abroad in 

 obstructions of the lower viscera, and especially in diseases of 

 the spleen. By combustion it yields a considerable quantity of 

 fixed salt, which is diuretic and aperient, and approaches to 

 Glauber's salts. The bark of the root is the most efficacious 

 part. A decoction of this is given in doses of 2 or 3 drachms, 

 or even an ounce ; of the wood and leaves double that quantity 

 may be taken.
