46. The Angelica Tree or Shrubby Aralia. Aralia 



spinosa. 



We owe this curious plant to Mr. Gibb. "Whin growing 

 vigourously and in good condition it is highly ornamental, 

 but it is liable to have the terminal bud winter killed, and 

 it has a bad habit of spreading freely from the root. It 

 requires moist ground. Our best specimens have had to be 

 removed, and some have been planted in the rear of the 

 grounds near the Medical building. 



47. Paulownia. Paulownia imperialis. 



This tree produces magnificent leaves and is very orna- 

 mental, but unfortunately its large shoots are annually 

 killed down. It has been on the ground for about twelve 

 years and sends up vigorous shoots annually. It is deserving 

 of cultivation even as a herbaceous plant, because of the 

 beautiful foliage. Our best specimen has been destroyed but 

 a smaller one still survives. 



48. Shrubby Hydrangea. Hydrangea arborescens. 



This beautiful, shrub presented by Mr. G-ibb, has proved 

 quite hardy and flowers profusely. Its large cymes of 

 flowers are very showy in autumn, and if taken into the 

 house can be dried and will remain fresh over winter. It 

 has now been introduced into many private gardens. The 

 best specimens I have seen are in the grounds of Mr. J. H. 

 E. Molson. 



49. The Horse Chestnut. jEscuIus hippocastanum. 



Specimens of this tree, presented by Mr. Young, have 

 been growing for many years on the grounds and flower 

 freely. I had hoped also to introduce the red variety, so 

 much cultivated in England ; but the specimens imported 

 proved too tender to endure the winter, though Mr. Lunn, 

 perhaps from some difference in soil or exposure, was more 

 successful, and had vigorous specimens for many years.
