The -whole of this group, composed of the clan of Spruces, assume the 

 form of a spiry cone or pyramid. P. Menziesii, nigra, Picea, and Kliu- 

 trew are rather quick growing trees. The branches are more or less 

 horizontal, with pendulous branchlets ; in some sorts the branches, 

 though at first horizontal, become depressed, with slightly raised points ; 

 and in 58 the branches are horizontal with drooping points and branch- 

 lets, presenting a very graceful appearance. P. Jezoensis is a native of 

 China, and is described by Mr. Fortune as a singularly graceful tree. 

 The foliage -of 35, 39, 42, 53 is a dark green ; of 56 a vivid green ; of 41, 

 is a pale green ; and 32, 33, 36, of a white glaucous ; and 58, 59, of a 

 pale glaucous green. P. Jezoensis is said to retain its leaves for seven 

 years ; P. Menziesii often loses part of its foliage during the first year. 

 The majority of this group will thrive well on inferior lands, in poor 

 clays and boggy soils; but they luxuriate in porous soils, in a moist 

 mountain climate, and come to perfection at higher altitudes than almost 

 all others. The Himalayan species, Khutrow and Morinda, ' require 

 strong loamy soils ; when planted in warm sunny situations, in dry soils,
