Sassafras variifolium, Comiwox Sassafras. This sjiecies is nearly at its 

 iforthern geographical limit in Amherst. From tin;e to time it suffers from 

 severe winter weather. A few fine large trees forty feet in height were 

 killed by the severe winter of 1917-18. This is especially attractive for its 

 beautiful autumn colors. It makes a splendid showing in woodland borders. 

 Such plantations represent its highest decorative use. 



Scladopitj/s verticUlata, Ujibrella-pixe. This beautiful oriental conifer was 

 early introduced to the campus and the college still has two exceptionally 

 fine specimens. It is a most attractive novelty and well worth using, either 

 as a specimen or in general coniferous plantations. 



Shepherdia arijentea. Silver Buffalobeury. A rather interesting, hardy, 

 large-growing shrub with silvery foliage, offering a striking contrast in mixed 

 plantings. Quite useful in its way. 



Sorharia arborea, Tree-spirea. A large lusty-growing shrub witii strong 

 pinnate leaves and large trusses of gorgeous white flowers. This seems to 

 be perfectly hardy and worthy of recommendation. 



So7'hus americana, American Mountaix-asii. This species is somewliat 

 less formal and symmetrical than the European mountain-ash and better 

 adapted to planting in woodland borders and garden borders generally. 



Sorbus aucuparia, Ei'ropean Mouxtain-ash. A well-known small tree, in- 

 teresting and useful for jilanting as single specimens on small grounds. At- 

 tractive for its fruit. 



Spiraea arguta, Garlaxd Spirea. One of the best of the small spireas, of 

 good habits and good foliage and -fairly attractive flowers. Suitable for gen- 

 jeral massing and grouping on lawns. One of the first to blossom in the 

 spring. 



Spiraea billiardi, Billiard Spirea. This species has been v idely sold and 

 used but seems to be less attractive than several of tiie other spireas. 



Spiraea bumaJda, Bu."MALnA Spirea. Another \\e]l-kno\\n sj)ecies for \\ liich 

 one might better substitute something else. 



Spiraea heriri/i, Hexry Spirea. A rather tall upright shrub of good foli- 

 age and an abundance of flowers. Good as a background plant in shrui)- 

 beries or foundation plantings. 



Spiraea latifolia, Pixk Meadow Spirea. A hardy native species suited to 

 rather moist land. 



Spiraea media, Oriextal Spirea. Much like the Henry spirea in all re- 

 spects, except not so tall, and may be used in like situations. 



Spiraea prunifoJia plena, Dot-rle Bridalwueatii. An old favorite and 

 most attractive when in good health. It is not entirely hardy, however, and 

 cannot be recommended for general planting in this latitude. 



Spiraea tomentosa. Hardiiack. A coarse, tough, hardy native species suit- 

 able for ])lanting in wild gardens. 



Spiraea thunbergi, Tiiuxherg Spirea. One of the most popular, small to 

 Hiedium in height, of pleasing habit and attractive foliage, which takes on a 

 fine rich color in autumn. The flowers are somewhat si)arse but pretty. The 

 whole plant is well worth using in spite of the fact that it is not entirely 

 hardy. The shoots kill back at the tips nearly every winter, but by removing
