Araucaria. 



Stock. — Araucaria imbricata or the Chilian species (Colymbea 

 imbricata) (from seed). Mode of Grafting. — Side-grafting with 

 an oblique cleft ; veneering (in February and August, under 

 glass) ; close to the ground. 



Remarks. — The genus Araucaria is sub -divided into Co- 

 lymbea, Eutacta, and Dammara. Colymbea imbricata and 

 the Brazilian species, Eutacta excelsa and E. Cunningharnii, 

 make excellent stocks for most kinds of Araucarias. When 

 there is a deficiency of stocks, varieties may be multiplied by 

 planting their leading shoots as cuttings ; however, as the 

 cutting of the leading shoot limits the number of branches 

 which will afterwards be produced, and as the success of 

 cuttings is not to be depended on so much as that of grafts, 

 it is much better in the first instance to plant cuttings of the 

 side-branches and, later on, to graft these cuttings with scions 

 taken from the upper part of the tree, and which have pushed 

 from the axils of the upper whorl of branches in consequence 

 of the pruning of the side -branches. 



Arbutus. 



Stock. — Arbutus pyrenaica (from seed). Mode of Grafting. 

 — Yeneering (in February and September, under glass) ; close 

 to the ground. 



Remarks. — Choose young stocks about two years old, as the 

 operation succeeds better when the tissues are tender. Place 

 the subjects, when grafted, under a cloche or frame, and 

 exclude the air for two months, which will assist the union 

 of the grafts. After this harden them off by degrees. 



Hawthorn. 



Stock— White Hawthorn (from seed). Mode of Grafting. 

 —Shield-budding (in July) ; cleft-grafting (in March) ; close 

 to the ground, and sometimes as standards.
