I translate from a letter lately received from Dr. Charles Bolle of Berlin, the following information concerning the fastigiate Silver Poplar, which has been called P. alba Bolleana, and which thanks to my correspondent will soon be tested in this country. Dr. Bolle's information is derived from a correspondent living at Teflis in Southern Russia. This gentleman says: "several very finely grown specimens of the pyramidal Silver Poplar may be seen in the public garden of Teflis. As the garden was laid out and planted by a, fugitive Persian Prince, whose name it still bears, it is probable that this tree was originally brought from Persia. The fastigiate Poplar is perfectly hardy in this climate where the thermometer falls to 4° Fahrenheit. It grows rapidly in any slightly moist soil, and is particularly noticeable for its habit and great size, completely dwarfing the Italian Poplar with which it is associated. The bark, even in old specimens is smoothed out as if it were polished; it is of a clear bluish green color without spots or cracks. The ramification is strong and characteristic.
The brilliant white of the lower side of the leaves, which remains unchanged in its purity throughout the summer, makes a strong contrast with the dark green of the upper side, producing a striking effect, and rendering this tree visible at a long distance. The wood of the fastigiate Poplar is of finer quality and more highly esteemed here than that of the other poplars. It is an ornamental tree of the first order, and I cannot too highly recommend it".
