Scots Pine. See Pinus sylvestris. 



Scots or Wych Elm. See Ulmus montana. 



Sea Buckthorn. See Hippopha rhamnoides. 



Sequoia gigantea (syn. Wellingtonia gigantea), 

 Mammoth Tree. Although many fine specimens 

 may be seen, this cannot be classed as one of the 

 most successful trees for planting in this country, 

 especially in some parts of the north. It grows 

 rapidly under good conditions and makes a fine 

 specimen. Often after a time it becomes rather 

 stunted in growth and loses its lower branches, 

 which spoils its appearance. A good soil-prepara- 

 tion is necessary previous to planting. It appears 

 to thrive best in deep, open, or rather sandy soils, 

 and under conditions of perfect drainage and in 

 an open situation. If it is planted anywhere near 

 the coast it must be sheltered, but it cannot be 

 recommended. This in its native habitat is a 

 gigantic tree. A specimen, which was known as 

 the " Father of the Forest," measured 435 feet in 

 height and no feet in circumference ; these were 

 the measurements of trunk of the tree when lying 

 on the ground, and it is stated that it must have 

 been much taller when living. Others are re- 

 corded upwards of 300 feet high. Evergreen ; 

 North- West America, 1853. 



Siberian Crab. See Pyrus pruni folia. 



Silver Fir. The popular name of Abies 

 pectinata.
