THE AMERICAN BOTANIST 29 



The loganberry is highly valued for making jam and jellies 

 and for canning, but one who is familiar with real raspberry 

 or blackberry jam is not likely to become enthusiastic over the 

 loganberry product. 



Valuable New Shrubs. — The shrubs commonly culti- 

 vated in Northern gardens, have been known for centuries. 

 Many are native species, possibly somewhat improved by cul- 

 tivation and the rest are introduced plants which travellers 

 have found cultivated in other regions. The discovery of 

 America supplied European gardens with a multitude of new 

 plants, while in our own country the discovery of China and 

 Siberia in a botanical sense, is having much the same effect. 

 In recent years a large number of promising shrubs have been 

 brought into the country, partly through the efforts of the 

 Arnold Arboretum and partly as the result of explorations 

 carried on by collectors, sent out by the National Government. 

 The flora of Siberia and China, though still little known, have 

 great interest for us from the fact that these countries have 

 a climate similar to our own and their plants, therefore, are 

 likely to prove hardy with us. In a list of the twelve best 

 shrubs recently introduced, we find several whose generic 

 names must be unfamiliar to the great army of flower growers. 

 Four of the twelve are species of Cotoneaster, namely C. 

 Jiu[^chcnsis, C. uiiilti flora, C. racenii flora and C. nit ens. The 

 first three have white flowers and when in bloom resemble 

 Spiraeas, to which in fact, they are closely related. The 

 fruits are red berries. Cotoneaster nitens has red flowers and 

 black fruits. A large yellow wild rose {R. Hugonis) and two 

 lilacs Syringa Szvegingozvii and (vS'. reflexa) are also on the 

 list. A species of bush honeysuckle (Dierz'illa florida var 

 venustuni) is reported to be the handsomest of all its race. 

 A yellow flowered shrub of early spring is P rinse pia Sinensis. 

 It has thorny stems and multitudes of blossoms and appears
