Trees on McGill University Grounds. 425 



36. The Dogwood. Gornus. (Species.) 



Of our different species of dogwood, that which seems 

 most deserving of cultivation as an ornamental tree is C. 

 paniculata. A fine tree-shaped specimen with very spread- 

 ing branches is in the grounds, and is still vigorous though 

 thirty years of age. 



37. The Elders. Sambucus canadensis and S. racemosa. 



Both species are cultivated in the College grounds. The 

 latter is perhaps the most important. It grows very vigor- 

 ously, is the first shrub to put forth its leaves and its not 

 very showy blossoms in spring, and when in fruit is gay 

 with its bunches of scarlet berries. It tends to have a 

 straggling habit of growth, but is easily pruned and kept 

 in shape. Its early vegetation in spring entitles it to 

 special consideration in our climate; and though it prefers 

 somewhat rich ground, it will grow well on dry banks. 



38. The High Cranberry. Viburnum opulus. 



Two specimens of this plant presented by the late C. 

 Dunkin, Esq., still exist in the grounds, and their fruit, 

 remaining over winter, produces a pretty appearance and 

 provides a meal to winter birds. The double variety known 

 as the snowball is a common ornamental shrub everywhere, 

 but the brilliant berries of the single variety entitle it to 

 consideration as an ornamental plant, though its flowers 

 are much less showy. 



39. The Sheep-Berry. Viburnum lentago. 



This species, indigenous on the mountain, is the only 

 other viburnum we have cultivated except the common 

 snowball. It grows well and flowers and fruits freely, and 

 is among other shrubs a pretty variety. In some parts of 

 the country its berries are used as fruit, but are of little 

 value.
