CUPKESSTJS NUTKAENSIS. 235 



of the 0. macroearpa of Hartweg are of frequent occurrence, but that 

 the former and its modifications are the most numerous. 



Cupressus macroearpa is a beautiful tree, tolerably hardy in the south 

 and west of England. For the spreading or horizontal branched variety 

 a space having a radius of not less than 20 feet should be allowed ; 

 the lower branches of some of the finest specimens in England having 

 attained that length. C. macroearpa is patient of the knife, and may 

 be pruned or headed back without injury ; it is, therefore, a good 

 plant for forming tall evergreen hedges in a sheltered situation. 

 Although a grand tree it cannot be recommended for the formation 

 of avenues, on account of the diversity of habit which it assumes, 

 whether raised from seed or from cuttings. 



Cupressus nutkaensis. — The Nootka Sound Cypress, in its 

 native country, is said to be a tall tree attaining a height of 

 from 80 to 100 feet, and having a rounded top.* Under culti- 

 vation it is of elongated pyramidal or nearly columnar form. The 

 branches are sub-erect or spreading, the branchlets distichously 

 arranged, with the extremities elegantly recurved and densely 

 clothed with imbricated closely appressed leaves, which are keeled 

 at the back and sharply pointed. This Cypress greatly resembles 

 0. Lawsoniana, from which it may be distinguished by its having 

 sulphury-yellow instead of red male catkins, by its more robust 

 habit, and its paler green foliage. 



Habitat. — Vancouver's Island, British Columbia, and Oregon, chiefly 

 between the 45th and 55th parallels. 



Introduced about 1850, from the Botanic Garden at St. Peters- 

 burgh. 



Cupressus nutkaensis argenteo-variegata has many of its 

 terminal branchlets creamy-white, with the laterals more or less 

 spotted with the same colour. 



Cupressus nutkaensis aureo-variegata has the same habit as 

 the type, with its green foliage varied here and there by sprigs 

 of light yellow. 



Cupressus nutkaensis compacta is of dwarf dense growth, 



* Dr Newberry, Pacific Bailway Eeport, p. 63, describes the individuals be saw as " trees 

 of moderate size, having much the appearance of Thuia occidentalis, when growing under 

 the most unfavourable circumstances,"
