Rediscovery of Species. 



In our list of 1896 a number of species were noted which had 

 not been reported for several years. Some of these have since been 

 rediscovered. Gentiana puberula Michx. was found at Bushnell's 

 Basin in 1914, only to have the station entirely destroyed before an- 

 other year. Buchnera Americana L. has been found in two localities. 

 Spiraea toiuentosa L. has been discovered in Simpson's woods. Abies 

 balsamea Mill, was found at Springwater and Gulick, Ontario 

 county. Although these are not in all cases the original stations, it 

 shows that the species noted are still to be found within our terri- 

 tory, and it is possible that others which have not been re- 

 ported of late years will be brought to light by the persistent search 

 of our botanists. 



Noteworthy Trees in Rochester and Vicinity. 

 By John Dunbar. 



During the past sixty to seventy years the city of Rochester has 

 been an important nursery center. A number of progressive nur- 

 serymen introduced many trees from various foreign sources to be 

 tested in their grounds and sold to customers if they proved to be 

 sufficiently hardy. The firm of Ellwanger & Barry did a great 

 deal of work, at great expense, in introducing, testing and distribut- 

 ing many interesting trees from various parts of the world, and 

 many of these are now to be seen in the City of Rochester and 

 vicinity. 



The Valley of the Genesee in the vicinity of Rochester is par- 

 ticularly adapted, through favorable climatic conditions, for grow- 

 ing many of the hardy trees of the north temperate zone. For 

 example, the Chinese Magnolias, and hybrids derived from these 

 Magnolias, grow with remarkable success in Rochester and vicinity. 

 Perhaps there is no other city in the northeastern United States 

 where these Magnolias grow any more freely. Paulon.'nia impcrialis, 

 Sieb. & Zucc, from China and Japan, is well known to be a tender 

 tree and fails in many parts of the northern United States, but it 

 succeeds very well in Rochester.
