332 A MANUAL 0! THE CONIFEEJ!. 



Sequoia semvpervirem, and Cwpressus macrocarpa (not included in the 

 above list), also attain their finest proportions within the influence of 

 the sea air, but require a sheltered south aspect and a moist loamy 

 soil. The common Yew, Spruce Fir, and the Larch Pine are the best 

 for chalk soils in an exposed situation. P. Strobus and P. excelsa are 

 dense on heavy soils; P. rigida, Abies nigra, Thuta occidentalis, and 

 Cupressus tliyoides are suitable for wet or moist places only. 



VII.— CONSERVATORY AND WINTER GARDEN. 



Coniferous trees and shrubs do not meet with much favour as 

 decorative plants for the Conservatory, except a few species, 

 limited chiefly to one genus (Araucaria), all of which are of 

 remarkably formal but elegant habit, and are densely furnished 

 with bright green foliage. To these may be added a few others 

 with distinct foliage that are too tender for out-door culture. The 

 following list includes all the tender Araucarias cultivated for con- 

 servatory decoration, with a few other kinds occasionally used for 

 the same purpose : — 



Araucaria excelsa 



„ „ glauca 



,, „ robusta and 



other varieties 



„ Cunninghami 



„ „ glauca 



,, Rulei 



„ „ elegans 



,, Cookii 



Araucaria Bidwilli 



„ brasiliensis 

 Callitris quadrivalvis 

 Libocedrus Doniana 

 Dacrydium elatum 



„ araucarioides 



Agathis robusta 

 „ australis 

 ,, Moorei 



VIII.— MEMORIAL TREES. 



The great age and size attained by many of the Coniferse, 

 together with their majestic aspect, render them especially appro- 

 priate for perpetuating the memory of events and circumstances. 

 The following list includes the most important trees remarkable 

 for longevity, stately aspect, and perfect hardiness in our climate. 

 None of them, however, will fulfil the object of a Memorial Tree 

 in the immediate vicinity of large towns. The antipathy of the 

 whole Order to the influence of smoke is irremediable.
