This is one of the most decorative Tamarisks in cultiva- 
tion, 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 that 
genus it thrives well in saline soil; but itis by no means 
dependent on a more than ordinary amount of salts in the 
ground. The flowers are usually rose-coloured; some- 
times, however, also white, or nearly so. Bunge described 
no fewer than eight varieties of 7’. Pallasi in his mono- 
graph, and Boissier added one more. Most of them are 
based on slight, and possibly inconstant, modifications of 
the inflorescences, whilst one or two represent evidently 
June Ist, 1907.
