A good working handbook of the (oer has been much wanted both 
by botanists and gardeners. The last general résumé, the Supplement to 
Count Sternberg’s well-known elaborate illustrated Monograph, is now forty 
years old ; and during these forty years a mass ew species has been 
added from the Mediterranean region, the Himalayas, and North America. 
Since the taste for Alpine gardening has spread, a much closer attention 
has been paid to the subordinate forms of the Alps and Pyrenees, and many 
of these, which were before included under the old types, have been 
published by Boissier, Schott, and others under specific names. We are 
told that one collection i iu England now eee 150 different forms in a
