Hi I > 



il! 



seen in the Botanic Garden, St. Petersburg; a tree 25 feet in 

 height and apparently quite hardy. F. Matitchurica, a fine tree, 

 quite hardy at St, Petersburg, and grows to a diameter of three feet 

 in its native land. 



GLYOYRRHIZA. 



G. ECHiNATA. — A shrub like a Bastard Indigo, bearing large 

 balls of rough tufted seeds. A very curious shrub, which we saw 

 in the Botanic Gardens at Kazan. 



G. Glabra is not so striking. 



HIPPOPHAE. 



The grey silky foliage of these shrubs makes them very attrac- 

 tive. Are they hardy ? I asked Dr. Regel. " I received them 

 from Central Europe and they proved tender ; I then procured 

 seed from Siberia, botanically the same, and they are quite hardy." 

 Such was Dr. Kegel's reply, the same old story, his experience 

 and mine, as far as I may be said to have any. 



The Hippophae salicifolia, which we saw at Proskau, was much 

 like a Rosemary Willow, and lacking in that white lustre which 

 others usually have. Siberica is more like the argeniea of Proskau, 

 bright and very ornamental.

W-M, 



In the Riga nurseries we first saw Siberica and Europcca grow- 

 ing side by siac. Siberica much the faster grower in nursery, 

 foliage slightly longer, more fringy, and clothing the branches 

 better than on Europoea. This larch was from the Ural Moun- 

 tains. Again at the Petrovskoe Academy there is a very fine 

 avenue of Siberica, a quarter of a mile or half a mile long. The 

 foliage very light in color ; the outline much less sharply conir 

 than other varieties. An avenue of even-sized trees about 30 feet 

 in height. In the Botanic Gardens at St. Petersburg we see it in 

 old age, a few old trees about 70 feet high. Alongside of it is
