42443. Tamarix pentandra Pall. Tamaricacese. Tamarisk. 

 Received as Tamarix pallasii Desv., var. macrostachys Bunge. 



" This shrub or small tree is one of the most decorative tamarisks in 

 cultivation, flowering in great profusion in July and August. In the 

 wild state it ranges from the Balkan Peninsula through southern Russia 

 to Turkestan and from Asia Minor to Persia, adorning the banks of rivers, 

 particularly in their lower reaches and estuaries. Like other species of 

 this genus, it thrives well in saline soils, but is by no means dependent 

 on a more than ordinary amount of salts in the ground. The flowers are 

 usually rose colored, but sometimes white or nearly so." (Curtis' s 

 Botanical Magazine, pi. 8138.)
